This version no longer piggy backs on ttyS0 (it # actually doesn't touch any files outside arch/alpha/kernel at all). It # does use a dynamic major for the tty piece of the driver. From # userspace, /dev/console is ok for most uses, but because of the 'noctty # = 1' at tty_tio.c:1329 (in the IS_SYSCONS_DEV section) using # /dev/console cannot result in a controlling tty so some things, like # 'resize' and bash job control don't work. For those uses, however, it's # easy enough to parse /proc/devices on the way up to get the major number # and create the specific device for the tty side of the driver. # # I made a distinction in kernel options as well. "srmcons" specifically # requests the early prints (as before) and "console=srm" requests the # full driver, including the early prints. The two options can be # combined with "console=srm" behavior resulting. The other change is that # if "console=srm" is specified, I don't unregister_srm_console before # console_init any more - that only happens in the "srmcons" case. That # way preferred console selection remains stable and "console=srm" doesn't # result in the early messages being repeated when the driver # re-registers. The use of "srmcons_allowed" is also eliminated due to the # "srmcons" vs. "console=srm" distinction. # -------------------------------------------- # 03/01/20 Jeff.Wiedemeier@hp.com 1.925.19.6 # [PATCH] remove srmcons_allowed implementation from marvel # # Remove unused marvel_srmcons_allowed implementation. # # /jeff # -------------------------------------------- # 03/01/20 Jeff.Wiedemeier@hp.com 1.925.19.7 # [PATCH] use CONFIG_EARLY_PRINTK to turn off "srmcons" prints # # Use CONFIG_EARLY_PRINTK to trigger disable_early_printk() call in # console_init (tty_io.c) to turn off "srmcons" prints rather than the # existing code in time.c. # # /jeff # -------------------------------------------- # 03/01/20 agrover@groveronline.com 1.925.1.27 # ACPI: Move more headers to include/acpi, and delete an unused header. # -------------------------------------------- # 03/01/20 agrover@groveronline.com 1.925.1.28 # CPUFREQ: Break out ACPI Perf code into its own module, under cpufreq # (Dominik Brodowski) # -------------------------------------------- # 03/01/20 agrover@groveronline.com 1.925.1.29 # ACPI: acpiphp.h includes both linux/acpi.h and acpi_bus.h.

This way it is much easier for software to # | tell that, for example, a scsi copy command will not work between two # | ATAPI devices. More importantly, hot plugging should theoretically # | work now, since Scsi_hosts are allocated and deallocated as ATAPI # | devices are added or removed. # | # | This change eliminates the idescsi_drives[] array and the # | ide_driver_t.id field that was used to index it. # | # | The idescsi_scsi_t data structure is now allocated at # | the end of the struct Scsi_Host rather than being a separate # | memory allocation. The calculation of various private pointers # | are changed slightly as a result. # | # | Other minor nits include making all global routines # | static and adding some missing error branches in # | init_idescsi_module. # | # | I've verified that I can at least read raw data # | from a DVD-ROM with with this change. # | # | When I unload this ide-scsi module, the stock ide-scsi module # | or the stock ide-cd modules in 2.5.56, I get what appears to be the # | same kernel bad memory reference, apparently due to some generic # | device device added to drivers/ide/ide.c.

Task B will then # sleep on the buffer and task A will loop, will run unlock_buffer() and then # wake task B. # # This state will continue until I/O completes against the buffer and kjournal # changes jh->j_list. # # Unless task A and task B happen to both have realtime scheduling policy - if # they do then kjournald will never run. The state is never cleared and your # box locks up. # # # The fix is to not do the `goto repeat;' until the buffer has been taken of # the shadow list. So we don't go and wake up the other waiter(s) until they # can actually proceed to use the buffer. # # The patch removes the exported sleep_on_buffer() function and simply exports # an existing function which provides access to a buffer_head's waitqueue # pointer. Which is a better interface anyway, because it permits the use of # wait_event(). # # This bug was introduced introduced into 2.4.20-pre5 and was faithfully ported # up. # -------------------------------------------- # 03/02/02 akpm@digeo.com 1.925.36.11 # [PATCH] slab poison checking fix # # Spotted by Andries Brouwer.

So when we're unmapping the # vma's of the old image, we are running under the new image's personality. # # This causes PPC64 to pass a 32-bit TASK_SIZE to unmap_vmas(), even when the # execing process had a 64-bit image. Because unmap_vmas() is not provided # with the correct virtual address span it does not unmap all the old image's # vma's and we go BUG_ON(mm->map_count) in exit_mmap(). # # The early SET_PERSONALITY() is required before we look up the interpreter # because the lookup of the executable has to happen under the alternate root # which SET_PERSONALITY() may set. # # Unfortunately this means that we're running flush_old_exec() under the new # exec's personality. Hence this bug. # # So what the patch does is to simply pass ~0UL into unmap_vmas(), which tells # it to unmap everything regardless of current personality. Which is what the # old open-coded VMA killer was doing. # # There remains the problem that some architectures are sometimes passing the # incorrect TASK_SIZE into tlb_finish_mmu(). They've always been doing that. # -------------------------------------------- # 03/02/02 akpm@digeo.com 1.925.36.30 # [PATCH] fix show_task oops # # Patch from Russell King # # show_task() attempts to calculate the amount of free space which hasn't been # written to on the kernel stack by reading from the base of the kernel stack # upwards. # # However, it mistakenly uses the task_struct pointer as the base of the stack, # which it isn't, and this can cause an oops. # # Here is a patch which uses the task thread pointer instead, which should be # located at the bottom of the kernel stack.

The code flow is now much # clearer, as more work is done from the USB probe/detach functions than # from auxillary functions. # (o) Names have been changed for newer conventions # (o) GUIDs have been removed # (o) The linked-list of devices has been removed, and it's associated # semaphore # (o) All code dealing with re-attaching a device to it's old association has # been removed # (o) Some spaces changed to tabs # (o) usb-storage now takes one directory under /proc/scsi instead of # one per virtual-HBA # (o) All control threads now have the same name. This could be changed back # to the old behavior, if enough people want it. # # Known problems: # (o) Testing, testing, testing # (o) More dead code needs to be cut # (o) It's a unclear how a LLD is supposed to cut off the flow of # commands, so that the unregister() call always succeeds.

We run clusters. Imagine a two node # cluster. Node1 pauses completely for some reason. There are multiple # reasons this can happen. A bad driver can udelay() for 90 seconds (qla used # to do this). zVM on S/390 can page Linux out for minutes at a time. # Anything that causes the box to freeze. Jiffies does *not* count during # this, so when Node1 returns it feels that no time has passed. # # Node2, however, has been counting time. When Node1 goes away, the Oracle # cluster manager starts looking for it. After a timeout, it gives up. It # then recovers any in-progress transactions from Node1. After that, it # starts new operations, modifying the data in ways that Node1 has no idea # about (it's still out to lunch). # # When Node1 finally returns (udelay() ends, zVM pages it in, whatever), any # I/O that it has queued or is about to queue will get sent to the disk. # Oops, you've just corrupted your shared data. # # hangcheck-timer should catch this and reboot the box. # # This is why Oracle wants this driver. We figure that such functionality # would be beneficial to others as well, so we posted to l-k. We'd all hope # that driver writers don't udelay() for 90s, but S/390 with zVM is still # around. Some folks might want to notice when it happens.

If so, it increments # jiffies appropriately. # # I was concerned that we'd be better off finding and fixing the misbehaving # drivers, but it turns out that the main culprits are system management cards # over which the kernel has no control. # # However John has added some debug code which will drop a backtrace on the # first five occurrences which will allow us to find-and-fix bad drivers if # overruns _are_ due to Linux software.

If one process is performing # a huge linear write, other processes end up waiting for a very long time # indeed. It appears that this is because the writing process just keeps on # hogging the CPU, returning to userspace, generating more dirty data, writing # it out, sleeping in get_request_wait, etc. All other throttled dirtiers get # starved. # # So just remove the wait altogether if it is just a memory-cleansing writeout. # The calling process will then throttle in balance_dirty_pages()'s call to # blk_congestion_wait(). # -------------------------------------------- # 03/02/04 akpm@digeo.com 1.925.40.29 # [PATCH] fix i_sem contention in sys_unlink() # # Truncates can take a very long time.

That's # somewhat significant. It means that the kernel is leaving stuff in the # queue, plugged, for too long. This testing was with a uniprocessor # preemptible kernel, which is particularly vulnerable to unplug latency # (submit some IO, get preempted before the unplug). # # This patch permits the removal of a lot of rather lame unplugging in # page reclaim and in the writeback code, which kicks the queues # (globally!) every four megabytes to get writeback underway. # # This patch doesn't use blk_run_queues(). It is able to kick just the # particular queue. # # The patch is not expected to make much difference really, except for # AIO. AIO needs a blk_run_queues() in its io_submit() call. For each # request. This means that AIO has to disable plugging altogether, # unless something like this patch does it for it.

This email includes some of our findings # about the way the interrupts are getting moved in the 2.5.52 kernel. # Also there is discussion and a patch for a new implementation. Let # me know what you think at nitin.a.kamble@intel.com # # Current implementation: # ====================== # We have found that the existing implementation works well on IA32 # SMP systems with light load of interrupts. Also we noticed that it # is not working that well under heavy interrupt load conditions on # these SMP systems. The observations are: # # * Interrupt load of each IRQ is getting balanced on CPUs independent # of load of other IRQs. Also the current implementation moves the # IRQs randomly. This works well when the interrupt load is light. But # we start seeing imbalance of interrupt load with existence of # multiple heavy interrupt sources. Frequently multiple heavily loaded # IRQs gets moved to a single CPU while other CPUs stay very lightly # loaded. To achieve a good interrupts load balance, it is important to # consider the load of all the interrupts together. # This further can be explained with an example of 4 CPUs and 4 # heavy interrupt sources. With the existing random movement approach, # the chance of each of these heavy interrupt sources moving to separate # CPUs is: (4/4)*(3/4)*(2/4)*(1/4) = 3/16. It means 13/16 = 81.25% of # the time the situation is, some CPUs are very lightly loaded and some # are loaded with multiple heavy interrupts. This causes the interrupt # load imbalance and results in less performance. In a case of 2 CPUs # and 2 heavily loaded interrupt sources, this imbalance happens # 1/2 = 50% of the times. This issue becomes more and more severe with # increasing number of heavy interrupt sources. # # * Another interesting observation is: We cannot see the imbalance # of the interrupt load from /proc/interrupts. (/proc/interrupts shows # the cumulative load of interrupts on all CPUs.) If the interrupt load # is imbalanced and this imbalance is getting rotated among CPUs # continuously, then /proc/interrupts will still show that the interrupt # load is going to processors very evenly. Currently at the frequency # (HZ/50) at which IRQs are moved across CPUs, it is not possible to # see any interrupt load imbalance happening. # # * We have also found that, in certain cases the static IRQ binding # performs better than the existing kernel distribution of interrupt # load. The reason is, in a well-balanced interrupt load situations, # these interrupts are unnecessarily getting frequently moved across # CPUs. This adds an extra overhead; also it takes off the CPU cache # warmth benefits. # This came out from the performance measurements done on a 4-way HT # (8 logical processors) Pentium 4 Xeon system running 8 copies of # netperf. The 4 NICs in the system taking different IRQs generated # sizable interrupt load with the help of connected clients. # # Here the netperf transactions/sec throughput numbers observed are: # # IRQs nicely manually bound to CPUs: 56.20K # The current kernel implementation of IRQ movement: 50.05K # ----------------------- # The static binding of IRQs has performed 12.28% better than the # current IRQ movement implemented in the kernel. # # * The current implementation does not distinguish siblings from the # HT (Hyper-Threading(tm)) enabled CPUs. It will be beneficial to # balance the interrupt load with respect to processor packages first, # and then among logical CPUs inside processor packages. # For example if we have 2 heavy interrupt sources and 2 processor # packages (4 logical CPUs); Assigning both the heavy interrupt sources # in different processor packages is better, it will use different # execution resources from the different processor packages. # # # # New revised implementation: # ========================== # We also have been working on a new implementation. The following # points are in main focus. # # * At any moment heavily loaded IRQs are distributed to different # CPUs to achieve as much balance as possible. # # * Lightly loaded interrupt sources are ignored from the load # balancing, as they do not cause considerable imbalance. # # * When the heavy interrupt sources are balanced, they are not moved # around. This also helps in keeping the CPU caches warm. # # * It has been made HT aware. While distributing the load, the load # on a processor package to which the logical CPUs belong to is also # considered. # # * In the situations of few (lesser than num_cpus) heavy interrupt # sources, it is not possible to balance them evenly. In such case # the existing code has been reused to move the interrupts. The # randomness from the original code has been removed. # # * The time interval for redistribution has been made flexible. It # varies as the system interrupt load changes. # # * A new kernel_thread is introduced to do the load balancing # calculations for all the interrupt sources. It keeps the balanace_maps # ready for interrupt handlers, keeping the overhead in the interrupt # handling to minimum. # # * It allows the disabling of the IRQ distribution from the boot loader # command line, if anybody wants to do it for any reason. # # * The algorithm also takes into account the static binding of # interrupts to CPUs that user imposes from the # /proc/irq/{n}/smp_affinity interface. # # # Throughput numbers with the netperf setup for the new implementation: # # Current kernel IRQ balance implementation: 50.02K transactions/sec # The new IRQ balance implementation: 56.01K transactions/sec # --------------------- # The performance improvement on P4 Xeon of 11.9% is observed. # # The new IRQ balance implementation also shows little performance # improvement on P6 (Pentium II, III) systems. # # On a P6 system the netperf throughput numbers are: # Current kernel IRQ balance implementation: 36.96K transactions/sec # The new IRQ balance implementation: 37.65K transactions/sec # --------------------- # Here the performance improvement on P6 system of about 2% is observed. # # # --------------------- # # Andrew Theurer did some testing of this patch on a quad # P4: # # # I got a chance to run the NetBench benchmark with your patch on 2.5.54-mjb2 # kernel. NetBench measures SMB/CIFS performance by using several SMB # clients (in this case 44 Windows 2000 systems), sending SMB requests to a # Linux server running Samba 2.2.3a+sendfile. Result is in throughput, # Mbps. Generally the network traffic on the server is 60% recv, 40% tx. # # I believe we have very similar systems. Mine is a 4 x 1.6 GHz, 1 MB L3 P4 # Xeon with 4 GB DDR memory (3.2 GB/sec I believe). The chipset is "Summit". # I also have more than one Intel e1000 adapters. # # I decided to run a few configurations, first with just one adapter, with # and without HT support in the kernel (acpi=off), then add another adapter # and test again with/without HT. # # Here are the results: # # 4P, no HT, 1 x e1000, no kirq: 1214 Mbps, 4% idle # 4P, no HT, 1 x e1000, kirq: 1223 Mbps, 4% idle, +0.74% # # I suppose we didn't see much of an improvement here because we never run # into the situation where more than one interrupt with a high rate is # routed to a single CPU on irq_balance. # # 4P, HT, 1 x e1000, no kirq: 1214 Mbps, 25% idle # 4P, HT, 1 x e1000, kirq: 1220 Mbps, 30% idle, +0.49% # # Again, not much of a difference just yet, but lots of idle time. We may # have reached the limit at which one logical CPU can process interrupts for # an e1000 adapter. There are other things I can probably do to help this, # like int delay, and NAPI, which I will get to eventually. # # 4P, HT, 2 x e1000, no kirq: 1269 Mbps, 23% idle # 4P, HT, 2 x e1000, kirq: 1329 Mbps, 18% idle +4.7% # # OK, almost 5% better! Probably has to do with a couple of things; the fact # that your code does not route two different interrupts to the same # core/different logical cpus (quite obvious by looking at /proc/interrupts), # and that more than one interrupt does not go to the same cpu if possible. # I suspect irq_balance did some of those [bad] things some of the time, and # we observed a bottleneck in int processing that was lower than with kirq. # # I don't think all of the idle time is because of a int processing # bottleneck. I'm just not sure what it is yet :) Hopefully something will # become obvious to me... # # Overall I like the way it works, and I believe it can be tweaked to work # with NUMA when necessary. I hope to have access to a specweb system on a # NUMA box soon, so we can verify that. # -------------------------------------------- # 03/02/06 akpm@digeo.com 1.925.49.10 # [PATCH] Fix futexes in huge pages # # Using a futex in a large page causes a kernel lockup in __pin_page() - # because __pin_page's page revalidation uses follow_page(), and follow_page() # doesn't work for hugepages. # # The patch fixes up follow_page() to return the appropriate 4k page for # hugepages. # # This incurs a vma lookup for each follow_page(), which is considerable # overhead in some situations.

If the user's address is in a huge page we're # elevting the refcount of a constituent 4k page, not the head page of the # high-order allocation unit. # # To solve this, a generic way of handling higher-order pages has been # implemented: # # - A higher-order page is called a "compound page". Chose this because # "huge page", "large page", "super page", etc all seem to mean different # things to different people. # # - The first (controlling) 4k page of a compound page is referred to as the # "head" page. # # - The remaining pages are tail pages. # # All pages have PG_compound set. All pages have their lru.next pointing at # the head page (even the head page has this). # # The head page's lru.prev, if non-zero, holds the address of the compound # page's put_page() function. # # The order of the allocation is stored in the first tail page's lru.prev. # This is only for debug at present. This usage means that zero-order pages # may not be compound. # # The above relationships are established for _all_ higher-order pages in the # page allocator.

It consists of a biggest set of changes from Roland, to # make threaded signals work. There were still tons of testcases and # boundary conditions (mostly in the signal/exit/ptrace area) that we did # not handle correctly. # # Roland's thread-signal semantics/behavior/ptrace fixes: # # - fix signal delivery race with do_exit() => signals are re-queued to the # 'process' if do_exit() finds pending unhandled ones. This prevents # signals getting lost upon thread-sys_exit(). # # - a non-main thread has died on one processor and gone to TASK_ZOMBIE, # but before it's gotten to release_task a sys_wait4 on the other # processor reaps it. It's only because it's ptraced that this gets # through eligible_child. Somewhere in there the main thread is also # dying so it reparents the child thread to hit that case. This means # that there is a race where P might be totally invalid. # # - forget_original_parent is not doing the right thing when the group # leader dies, i.e. reparenting threads to init when there is a zombie # group leader. Perhaps it doesn't matter for any practical purpose # without ptrace, though it makes for ppid=1 for each thread in core # dumps, which looks funny. Incidentally, SIGCHLD here really should be # p->exit_signal. # # - one of the gdb tests makes a questionable assumption about what kill # will do when it has some threads stopped by ptrace and others running. # # exit races: # # 1. Processor A is in sys_wait4 case TASK_STOPPED considering task P. # Processor B is about to resume P and then switch to it. # # While A is inside that case block, B starts running P and it clears # P->exit_code, or takes a pending fatal signal and sets it to a new # value. Depending on the interleaving, the possible failure modes are: # a. A gets to its put_user after B has cleared P->exit_code # => returns with WIFSTOPPED, WSTOPSIG==0 # b. A gets to its put_user after B has set P->exit_code anew # => returns with e.g. WIFSTOPPED, WSTOPSIG==SIGKILL # # A can spend an arbitrarily long time in that case block, because # there's getrusage and put_user that can take page faults, and # write_lock'ing of the tasklist_lock that can block. But even if it's # short the race is there in principle. # # 2. This is new with NPTL, i.e. CLONE_THREAD. # Two processors A and B are both in sys_wait4 case TASK_STOPPED # considering task P. # # Both get through their tests and fetches of P->exit_code before either # gets to P->exit_code = 0. => two threads return the same pid from # waitpid. # # In other interleavings where one processor gets to its put_user after # the other has cleared P->exit_code, it's like case 1(a). # # # 3. SMP races with stop/cont signals # # First, take: # # kill(pid, SIGSTOP); # kill(pid, SIGCONT); # # or: # # kill(pid, SIGSTOP); # kill(pid, SIGKILL); # # It's possible for this to leave the process stopped with a pending # SIGCONT/SIGKILL. That's a state that should never be possible. # Moreover, kill(pid, SIGKILL) without any repetition should always be # enough to kill a process. (Likewise SIGCONT when you know it's # sequenced after the last stop signal, must be sufficient to resume a # process.) # # 4. take: # # kill(pid, SIGKILL); // or any fatal signal # kill(pid, SIGCONT); // or SIGKILL # # it's possible for this to cause pid to be reaped with status 0 # instead of its true termination status. The equivalent scenario # happens when the process being killed is in an _exit call or a # trap-induced fatal signal before the kills. # # plus i've done stability fixes for bugs that popped up during # beta-testing, and minor tidying of Roland's changes: # # - a rare tasklist corruption during exec, causing some very spurious and # colorful crashes. # # - a copy_process()-related dereference of already freed thread structure # if hit with a SIGKILL in the wrong moment. # # - SMP spinlock deadlocks in the signal code # # this patchset has been tested quite well in the 2.4 backport of the # threading changes - and i've done some stresstesting on 2.5.59 SMP as # well, and did an x86 UP testcompile + testboot as well. # -------------------------------------------- # 03/02/06 markh@osdl.org 1.925.48.11 # [PATCH] fix megaraid driver compile error # # This moves access of the host element to device since host has been # removed from struct scsi_cmnd. # -------------------------------------------- # 03/02/06 drow@nevyn.them.org 1.925.22.5 # Signal handling bugs for thread exit + ptrace # -------------------------------------------- # 03/02/06 colpatch@us.ibm.com 1.925.48.12 # [PATCH] Broken CLEAR_BITMAP() macro # # The CLEAR_BITMAP() macro in include/linux/types.h is broken and doesn't # round the bitmap size to the proper 'long' boundary. # # This fixes it by creating a macro BITS_TO_LONGS that just rounds a # number of bits up to the closest number of unsigned longs.

While at it, I noticed that one of the races I fixed in the # TASK_STOPPED case actually can happen earlier. Between read_unlock and # write_lock_irq, another thread could reap the process and make P invalid, # so now I do get_task_struct before read_unlock and then the existing race # checks catch all scenarios. # # Aside from the aforementioned race tweak, the code should be the same as # in the previous patch (that Ingo and I have tested more thoroughly) # modulo being moved into functions and some reformatting and comment # changes. # # Oh, my old patch had one case where it failed to retake the read lock after # a race bailout that I just noticed reading over it.

This table contains one entry for each system call. +By default, a system call is handled by fsys_fallback_syscall(). This +routine takes care of entering (full) kernel mode and calling the +normal Linux system call handler. For performance-critical system +calls, it is possible to write a hand-tuned fsyscall_handler. For +example, fsys.S contains fsys_getpid(), which is a hand-tuned version +of the getpid() system call. + +The entry and exit-state of an fsyscall handler is as follows: + +** Machine state on entry to fsyscall handler: + + - r10 = 0 + - r11 = saved ar.pfs (a user-level value) + - r15 = system call number + - r16 = "current" task pointer (in normal kernel-mode, this is in r13) + - r32-r39 = system call arguments + - b6 = return address (a user-level value) + - ar.pfs = previous frame-state (a user-level value) + - PSR.be = cleared to zero (i.e., little-endian byte order is in effect) + - all other registers may contain values passed in from user-mode + +** Required machine state on exit to fsyscall handler: + + - r11 = saved ar.pfs (as passed into the fsyscall handler) + - r15 = system call number (as passed into the fsyscall handler) + - r32-r39 = system call arguments (as passed into the fsyscall handler) + - b6 = return address (as passed into the fsyscall handler) + - ar.pfs = previous frame-state (as passed into the fsyscall handler) + +Fsyscall handlers can execute with very little overhead, but with that +speed comes a set of restrictions: + + o Fsyscall-handlers MUST check for any pending work in the flags + member of the thread-info structure and if any of the + TIF_ALLWORK_MASK flags are set, the handler needs to fall back on + doing a full system call (by calling fsys_fallback_syscall). + + o Fsyscall-handlers MUST preserve incoming arguments (r32-r39, r11, + r15, b6, and ar.pfs) because they will be needed in case of a + system call restart. Of course, all "preserved" registers also + must be preserved, in accordance to the normal calling conventions. + + o Fsyscall-handlers MUST check argument registers for containing a + NaT value before using them in any way that could trigger a + NaT-consumption fault. If a system call argument is found to + contain a NaT value, an fsyscall-handler may return immediately + with r8=EINVAL, r10=-1. + + o Fsyscall-handlers MUST NOT use the "alloc" instruction or perform + any other operation that would trigger mandatory RSE + (register-stack engine) traffic. + + o Fsyscall-handlers MUST NOT write to any stacked registers because + it is not safe to assume that user-level called a handler with the + proper number of arguments. + + o Fsyscall-handlers need to be careful when accessing per-CPU variables: + unless proper safe-guards are taken (e.g., interruptions are avoided), + execution may be pre-empted and resumed on another CPU at any given + time. + + o Fsyscall-handlers must be careful not to leak sensitive kernel' + information back to user-level. In particular, before returning to + user-level, care needs to be taken to clear any scratch registers + that could contain sensitive information (note that the current + task pointer is not considered sensitive: it's already exposed + through ar.k6). + +The above restrictions may seem draconian, but remember that it's +possible to trade off some of the restrictions by paying a slightly +higher overhead. For example, if an fsyscall-handler could benefit +from the shadow register bank, it could temporarily disable PSR.i and +PSR.ic, switch to bank 0 (bsw.0) and then use the shadow registers as +needed. In other words, following the above rules yields extremely +fast system call execution (while fully preserving system call +semantics), but there is also a lot of flexibility in handling more +complicated cases. + +* Signal handling + +The delivery of (asynchronous) signals must be delayed until fsys-mode +is exited. This is acomplished with the help of the lower-privilege +transfer trap: arch/ia64/kernel/process.c:do_notify_resume_user() +checks whether the interrupted task was in fsys-mode and, if so, sets +PSR.lp and returns immediately. When fsys-mode is exited via the +"br.ret" instruction that lowers the privilege level, a trap will +occur. The trap handler clears PSR.lp again and returns immediately. +The kernel exit path then checks for and delivers any pending signals. + +* PSR Handling + +The "epc" instruction doesn't change the contents of PSR at all. This +is in contrast to a regular interruption, which clears almost all +bits. Because of that, some care needs to be taken to ensure things +work as expected.

These variables - are ancient! They are also specific to the i386 architecture. - They really should be replaced with CONFIG_* options. - - MAKEBOOT - - This variable is defined and used only inside the main arch - Makefiles. The top Makefile should not export it. - - INSTALL_PATH - - This variable defines a place for the arch Makefiles to install - the resident kernel image and System.map file. + Example: + obj-y += foo.o - INSTALL_MOD_PATH, MODLIB + This tell kbuild that there is one object in that directory named + foo.o. foo.o will be build from foo.c or foo.S. - $(INSTALL_MOD_PATH) specifies a prefix to $(MODLIB) for module - installation. This variable is not defined in the Makefile but - may be passed in by the user if desired. + If foo.o shall be built as a module, the variable obj-m is used. + Therefore the following pattern is often used: - $(MODLIB) specifies the directory for module installation. - The top Makefile defines $(MODLIB) to - $(INSTALL_MOD_PATH)/lib/modules/$(KERNELRELEASE). The user may - override this value on the command line if desired. + Example: + obj-$(CONFIG_FOO) += foo.o - CONFIG_SHELL + $(CONFIG_FOO) evaluates to either y (for built-in) or m (for module). + If CONFIG_FOO is neither y nor m, then the file will not be compiled + nor linked. - This variable is private between Makefile and Rules.make. - Arch makefiles and subdirectory Makefiles should never use this. +--- 3.2 Built-in object goals - obj-y - MODVERFILE + The kbuild Makefile specifies object files for vmlinux + in the lists $(obj-y). These lists depend on the kernel + configuration. - An internal variable. This doesn't need to be exported, as it - is never used outside of the top Makefile. + Kbuild compiles all the $(obj-y) files. It then calls + "$(LD) -r" to merge these files into one built-in.o file. + built-in.o is later linked into vmlinux by the parent Makefile. - MAKE, MAKEFILES + The order of files in $(obj-y) is significant. Duplicates in + the lists are allowed: the first instance will be linked into + built-in.o and succeeding instances will be ignored. - Some variables internal to GNU Make. + Link order is significant, because certain functions + (module_init() / __initcall) will be called during boot in the + order they appear. So keep in mind that changing the link + order may e.g. change the order in which your SCSI + controllers are detected, and thus you disks are renumbered. - $(MAKEFILES) in particular is used to force the arch Makefiles - and subdirectory Makefiles to read $(TOPDIR)/.config without - including it explicitly. (This was an implementational hack - and could be fixed). + Example: + #drivers/isdn/i4l/Makefile + # Makefile for the kernel ISDN subsystem and device drivers. + # Each configuration option enables a list of files. + obj-$(CONFIG_ISDN) += isdn.o + obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o +--- 3.3 Loadable module goals - obj-m + $(obj-m) specify object files which are built as loadable + kernel modules. -=== 5 The structure of an arch Makefile + A module may be built from one source file or several source + files. In the case of one source file, the kbuild makefile + simply adds the file to $(obj-m). + Example: + #drivers/isdn/i4l/Makefile + obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o + Note: In this example $(CONFIG_ISDN_PPP_BSDCOMP) evaluates to 'm' ---- 5.1 Architecture-specific variables + If a kernel module is built from several source files, you specify + that you want to build a module in the same way as above. -The top Makefile includes one arch Makefile file, arch/$(ARCH)/Makefile. -This section describes the functions of the arch Makefile. + Kbuild needs to know which the parts that you want to build your + module from, so you have to tell it by setting an + $(-objs) variable. -An arch Makefile extends some of the top Makefile's variables with -architecture-specific values. + Example: + #drivers/isdn/i4l/Makefile + obj-$(CONFIG_ISDN) += isdn.o + isdn-objs := isdn_net_lib.o isdn_v110.o isdn_common.o - SUBDIRS + In this example, the module name will be isdn.o. Kbuild will + compile the objects listed in $(isdn-objs) and then run + "$(LD) -r" on the list of these files to generate isdn.o. - The top Makefile defines $(SUBDIRS). The arch Makefile extends - $(SUBDIRS) with a list of architecture-specific directories. + Kbuild recognises objects used for composite objects by the suffix + -objs, and the suffix -y. This allows the Makefiles to use + the value of a CONFIG_ symbol to determine if an object is part + of a composite object. Example: + #fs/ext2/Makefile + obj-$(CONFIG_EXT2_FS) += ext2.o + ext2-y := balloc.o bitmap.o + ext2-$(CONFIG_EXT2_FS_XATTR) += xattr.o + + In this example xattr.o is only part of the composite object + ext2.o, if $(CONFIG_EXT2_FS_XATTR) evaluates to 'y'. - # arch/alpha/Makefile - - SUBDIRS := $(SUBDIRS) arch/alpha/kernel arch/alpha/mm \ - arch/alpha/lib arch/alpha/math-emu - - This list may depend on the configuration: + Note: Of course, when you are building objects into the kernel, + the syntax above will also work. So, if you have CONFIG_EXT2_FS=y, + kbuild will build an ext2.o file for you out of the individual + parts and then link this into built-in.o, as you would expect. - # arch/arm/Makefile +--- 3.4 Objects which export symbols - export-objs - ifeq ($(CONFIG_ARCH_ACORN),y) - SUBDIRS += drivers/acorn - ... - endif + When using loadable modules, not every global symbol in the + kernel / other modules is automatically available, only those + explicitly exported are available for your module. - CPP, CC, AS, LD, AR, NM, STRIP, OBJCOPY, OBJDUMP - CPPFLAGS, CFLAGS, CFLAGS_KERNEL, MODFLAGS, AFLAGS, LDFLAGS + To make a symbol available for use in modules, to "export" it, + use the EXPORT_SYMBOL() directive in your source. In + addition, you need to list all object files which export symbols + (i.e. their source contains an EXPORT_SYMBOL() directive) in the + Makefile variable $(export-objs). - The top Makefile defines these variables, and the arch Makefile - extends them. + Example: + #drivers/isdn/i4l/Makefile + # Objects that export symbols. + export-objs := isdn_common.o - Many arch Makefiles dynamically run the target C compiler to - probe supported options: + since isdn_common.c contains - # arch/i386/Makefile + EXPORT_SYMBOL(register_isdn); - # prevent gcc from keeping the stack 16 byte aligned - CFLAGS += $(shell if $(CC) -mpreferred-stack-boundary=2 \ - -S -o /dev/null -xc /dev/null >/dev/null 2>&1; \ - then echo "-mpreferred-stack-boundary=2"; fi) + which makes the function register_isdn available to + low-level ISDN drivers. + There exist a EXPORT_SYMBOL_GPL() variant with similar functionality, + but more restrictive with what may use that symbol. The requirement + to list the .o file in export-objs is the same. - And, of course, $(CFLAGS) can depend on the configuration: +--- 3.5 Library file goals - L_TARGET - # arch/i386/Makefile + Instead of building a built-in.o file, you may also + build an archive which again contains objects listed in $(obj-y). + This is normally not necessary and only used in lib/ and + arch/$(ARCH)/lib directories. + Only the name lib.a is allowed. - ifdef CONFIG_M386 - CFLAGS += -march=i386 - endif + Example: + #arch/i386/lib/Makefile + L_TARGET := lib.a + obj-y := checksum.o delay.o - ifdef CONFIG_M486 - CFLAGS += -march=i486 - endif + This will create a library lib.a based on checksum.o and delay.o. - ifdef CONFIG_M586 - CFLAGS += -march=i586 - endif +--- 3.6 Descending down in directories - Some arch Makefiles redefine the compilation commands in order - to add architecture-specific flags: + A Makefile is only responsible for building objects in its own + directory. Files in subdirectories should be taken care of by + Makefiles in these subdirs. The build system will automatically + invoke make recursively in subdirectories, provided you let it know of + them. - # arch/s390/Makefile + To do so obj-y and obj-m are used. + ext2 lives in a separate directory, and the Makefile present in fs/ + tells kbuild to descend down using the following assignment. - LD=$(CROSS_COMPILE)ld -m elf_s390 - OBJCOPY=$(CROSS_COMPILE)objcopy -O binary -R .note -R .comment -S + Example: + #fs/Makefile + obj-$(CONfIG_EXT2_FS) += ext2/ + If CONFIG_EXT2_FS is set to either 'y' (built-in) or 'm' (modular) + the corresponding obj- variable will be set, and kbuild will descend + down in the ext2 directory. + Kbuild only uses this information to decide that it needs to visit + the directory, it is the Makefile in the subdirectory that + specifies what is modules and what is built-in. + It is good practice to use a CONFIG_ variable when assigning directory + names. This allows kbuild to totally skip the directory if the + corresponding CONFIG_ option is neither 'y' nor 'm'. ---- 5.2 Vmlinux build variables +--- 3.7 Compilation flags -An arch Makefile cooperates with the top Makefile to define variables -which specify how to build the vmlinux file.

This includes generated files such as host programs. +Kbuild knows targets listed in $(host-progs) and $(EXTRA_TARGETS) and +they are all deleted during "make clean". +Files matching the patterns "*.[oas]", "*.ko", plus some additional files +generated by kbuild are deleted all over the kernel src tree when +"make clean" is executed. - The subdirectory Makefile specifies object files for vmlinux - in the lists $(obj-y). These lists depend on the kernel - configuration. +Additional files can be specified by means of $(clean-files). - Rules.make compiles all the $(obj-y) files. It then calls - "$(LD) -r" to merge these files into one .o file with the name - $(O_TARGET). This $(O_TARGET) is later linked into vmlinux by - a parent Makefile. + Example: + #drivers/pci/Makefile + clean-files := devlist.h classlist.h - The order of files in $(obj-y) is significant. Duplicates in - the lists are allowed: the first instance will be linked into - $(O_TARGET) and succeeding instances will be ignored. +When executing "make clean", the two files "devlist.h classlist.h" will +be deleted. Kbuild knows that files specified by $(clean-files) are +located in the same directory as the makefile. - Link order is significant, because certain functions - (module_init() / __initcall) will be called during boot in the - order they appear. So keep in mind that changing the link - order may e.g. change the order in which your SCSI - controllers are detected, and thus you disks are renumbered. +Usually kbuild descends down in subdirectories due to "obj-* := dir/", +but in the architecture makefiles where the kbuild infrastructure +is not sufficent this sometimes needs to be explicit. Example: + #arch/i386/boot/Makefile + subdir- := compressed/ - # Makefile for the kernel ISDN subsystem and device drivers. - - # The target object and module list name. - - O_TARGET := vmlinux-obj.o +The above assignment instructs kbuild to descend down in the +directory compressed/ when "make clean" is executed. - # Each configuration option enables a list of files. +To support the clean infrastructure in the Makefiles that builds the +final bootimage there is an optional target named archclean: - obj-$(CONFIG_ISDN) += isdn.o - obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o + Example: + #arch/i386/Makefile + archclean: + $(Q)$(MAKE) $(clean)=arch/i386/boot - # The global Rules.make. +When "make clean" is executed, make will descend down in arch/i386/boot, +and clean as usual. The Makefile located in arch/i386/boot/ may use +the subdir- trick to descend further down. - include $(TOPDIR)/Rules.make +Note 1: arch/$(ARCH)/Makefile cannot use "subdir-", because that file is +included in the top level makefile, and the kbuild infrastructure +is not operational at that point. ---- 7.3 Library file goals +Note 2: All directories listed in core-y, libs-y, drivers-y and net-y will +be visited during "make clean". - L_TARGET +=== 6 Architecture Makefiles - Instead of building an O_TARGET object file, you may also - build an archive which again contains objects listed in - $(obj-y). This is normally not necessary and only used in - the lib, arch/$(ARCH)/lib directories. +The top level Makefile sets up the environment and does the preparation, +before starting to descend down in the individual directories. +The top level makefile contains the generic part, whereas the +arch/$(ARCH)/Makefile contains what is required to set-up kbuild +to the said architecture. +To do so arch/$(ARCH)/Makefile sets a number of variables, and defines +a few targets. +When kbuild executes the following steps are followed (roughly): +1) Configuration of the kernel => produced .config +2) Store kernel version in include/linux/version.h +3) Symlink include/asm to include/asm-$(ARCH) +4) Updating all other prerequisites to the target prepare: + - Additional prerequisites are specified in arch/$(ARCH)/Makefile +5) Recursively descend down in all directories listed in + init-* core* drivers-* net-* libs-* and build all targets. + - The value of the above variables are extended in arch/$(ARCH)/Makefile. +6) All object files are then linked and the resulting file vmlinux is + located at the root of the src tree. + The very first objects linked are listed in head-y, assigned by + arch/$(ARCH)/Makefile. +7) Finally the architecture specific part does any required post processing + and builds the final bootimage. + - This includes building boot records + - Preparing initrd images and the like ---- 7.4 Loadable module goals - obj-m +--- 6.1 Set variables to tweak the build to the architecture - $(obj-m) specify object files which are built as loadable - kernel modules. + LDFLAGS Generic $(LD) options - A module may be built from one source file or several source - files. In the case of one source file, the subdirectory - Makefile simply adds the file to $(obj-m) + Flags used for all invocations of the linker. + Often specifying the emulation is sufficient. Example: + #arch/s390/Makefile + LDFLAGS := -m elf_s390 + Note: EXTRA_LDFLAGS and LDFLAGS_$@ can be used to further customise + the flags used. See chapter 7. + + LDFLAGS_MODULE Options for $(LD) when linking modules - obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o + LDFLAGS_MODULE is used to set specific flags for $(LD) when + linking the .ko files used for modules. + Default is "-r", for relocatable output. - If a kernel module is built from several source files, you specify - that you want to build a module in the same way as above. + LDFLAGS_vmlinux Options for $(LD) when linking vmlinux - However, the build system of course needs to know which the parts - are that you want to build your module of, so you have to tell it - by setting an $(-objs) variable. + LDFLAGS_vmlinux is used to specify additional flags to pass to + the linker when linking the final vmlinux. + LDFLAGS_vmlinux uses the LDFLAGS_$@ support. Example: + #arch/i386/Makefile + LDFLAGS_vmlinux := -e stext - obj-$(CONFIG_ISDN) += isdn.o - - isdn-objs := isdn_net.o isdn_tty.o isdn_v110.o isdn_common.o - - In this example, the module name will be isdn.o. Rules.make - will compile the objects listed in $(isdn-objs) and then run - "$(LD) -r" on the list of these files to generate isdn.o - - Note: Of course, when you are building objects into the kernel, - the syntax above will also work. So, if you have CONFIG_ISDN=y, - the build system will build an isdn.o for you out of the individual - parts and then link this into the $(O_TARGET), as you'd expect. - + LDFLAGS_BLOB Options for $(LD) when linking the initramfs blob ---- 7.5 Objects which export symbols - - export-objs + The image used for initramfs is made during the build process. + LDFLAGS_BLOB is used to specify additional flags to be used when + creating the initramfs_data.o file. + Example: + #arch/i386/Makefile + LDFLAGS_BLOB := --format binary --oformat elf32-i386 - When using loadable modules, not every global symbol in the - kernel / other modules is automatically available, only those - explicitly exported are available for your module. + OBJCOPYFLAGS objcopy flags - To make a symbol available for use in modules, to "export" it, - use the EXPORT_SYMBOL() directive in your source. In - addition, you need to list all object files which export symbols - (i.e. their source contains an EXPORT_SYMBOL() directive) in the - Makefile variable $(export-objs). + When $(call if_changed,objcopy) is used to translate a .o file, + then the flags specified in OBJCOPYFLAGS will be used. + $(call if_changed,objcopy) is often used to generate raw binaries on + vmlinux.

This tree is designed only for compilation on 2.5 or + later environment. The latter, alsa-driver, contains many subtle + files for compiling the ALSA driver on the outside of Linux + kernel like configure script, the wrapper functions for older, + 2.2 and 2.4 kernels, to adapt the latest kernel API, + and additional drivers which are still in development or in + tests. The drivers in alsa-driver tree will be moved to + alsa-kernel (eventually 2.5 kernel tree) once when they are + finished and confirmed to work fine. + + + + The file tree structure of ALSA driver is depicted below. Both + alsa-kernel and alsa-driver have almost the same file + structure, except for core directory.

+ core/oss + + + The codes for PCM and mixer OSS emulation modules are stored + in this directory. The rawmidi OSS emulation is included in + the ALSA rawmidi code since it's quite small. The sequencer + code is stored in core/seq/oss directory (see + + below). + +
+ +
+ core/ioctl32 + + + This directory contains the 32bit-ioctl wrappers for 64bit + architectures such like x86-64, ppc64 and sparc64. For 32bit + and alpha architectures, these are not compiled. + +
+ +
+ core/seq + + This and its sub-directories are for the ALSA + sequencer. This directory contains the sequencer core and + primary sequencer modules such like snd-seq-midi, + snd-seq-virmidi, etc. They are compiled only when + CONFIG_SND_SEQUENCER is set in the kernel + config. + +
+ +
+ core/seq/oss + + This contains the OSS sequencer emulation codes. + +
+ +
+ core/seq/instr + + This directory contains the modules for the sequencer + instrument layer. + +
+
+ +
+ include directory + + This is the place for the public header files of ALSA drivers, + which are to be exported to the user-space, or included by + several files at different directories. Basically, the private + header files should not be placed in this directory, but you may + still find files there, due to historical reason :) + +
+ +
+ drivers directory + + This directory contains the non-architecture-specific + codes. For example, the dummy pcm driver and the serial MIDI + driver are found in this directory. In the sub-directories, + there are the codes for components which are independent from + bus and cpu architectures. + + +
+ drivers/mpu401 + + The MPU401 and MPU401-UART modules are stored here. + +
+ +
+ drivers/opl3 + + The OPL3 FM-synth stuff is found here. + +
+
+ +
+ i2c directory + + This contains the ALSA i2c components. + + + + Although there is a standard i2c layer on Linux, ALSA uses its + own i2c codes for some cards, because the soundcard needs only a + simple operation and the standard API is too complicated for + such a purpose. + + +
+ i2c/l3 + + This is a sub-directory for ARM L3 i2c. + +
+
+ +
+ synth directory + + This contains the synth middle-level modules. + + + + So far, there is only Emu8000/Emu10k1 synth driver under + synth/emux sub-directory. + +
+ +
+ pci directory + + This and its sub-directories hold the top-level card modules + for PCI soundcards. + + + + The drivers compiled from a single file is stored directly on + pci directory, while the drivers with several source files are + stored on its own sub-directory (e.g. emu10k1, ice1712). + +
+ +
+ isa directory + + This and its sub-directories hold the top-level card modules + for ISA soundcards. + +
+ +
+ arm, ppc, and sparc directories + + These are for the top-level card modules which are + architecture specific. + +
+ +
+ usb directory + + This contains the USB-audio driver. On the latest version, the + USB MIDI driver is integrated together with usb-audio driver. + +
+ +
+ pcmcia directory + + The PCMCIA, especially PCCard drivers will go here. CardBus + drivers will be on pci directory, because its API is identical + with the standard PCI cards. + + + + At this moment, only VX-pocket driver exists. + +
+ +
+ oss directory + + The OSS/Lite source files are stored here on Linux 2.5 (or + later) tree. (In the ALSA driver tarball, it's empty, of course :) + +
+ + + + + + + + Basic Flow for PCI Drivers + +
+ Outline + + The minimum flow of PCI soundcard is like the following: + + + define the PCI ID table (see the section + PCI Entries + ). + create probe() callback. + create remove() callback. + create pci_driver table which contains the three pointers above. + create init() function just calling pci_module_init() to register the pci_driver table defined above. + create exit() function to call pci_unregister_driver() function. + + +

+ +
+ Constructor + + The real constructor of PCI drivers is probe callback. The + probe callback and other component-constructors which are called + from probe callback should be defined with + __devinit prefix. You + cannot use __init prefix for them, + because any PCI device could be a hotplug device. + + + + In the probe callback, the following scheme is often used. + + +
+ 1) Check and increment the device index. + + + += SNDRV_CARDS) + return -ENODEV; + if (!enable[dev]) { + dev++; + return -ENOENT; + } +]]> + + + + where enable[dev] is the module option. + + + + At each time probe callback is called, check the + availability of the device. If not available, simply increment + the device index and returns. dev will be incremented also + later (step + 7). + +
+ +
+ 2) Create a card instance + + + + + + + + + + The detail will be explained in the section + + Management of Cards and Components. + +
+ +
+ 3) Create a main component + + In this part, the PCI resources are allocated. + + + + + + + + The detail will be explained in the section PCI Resource + Managements. + +
+ +
+ 4) Create other components, such as mixer, MIDI, etc. + + Here you define the basic components such as + PCM, + mixer (e.g. AC97), + MIDI (e.g. MPU-401), + and other interfaces. + Also, if you want a proc + file, define it here, too. + +
+ +
+ 5) Set the driver ID and name strings. + + + +driver, "My Chip"); + strcpy(card->shortname, "My Own Chip 123"); + sprintf(card->longname, "%s at 0x%lx irq %i", + card->shortname, chip->ioport, chip->irq); +]]> + + + + The driver field holds the minimal ID string of the + chip. This is referred by alsa-lib's configurator, so keep it + simple but unique. + Even the same driver can have different driver IDs to + distinguish the functionality of each chip type. + + + + The shortname field is a string shown as more verbose + name. The longname field contains the information which is + shown in /proc/asound/cards. + +
+ +
+ 6) Register the card instance. + + + + + + + + + + Will be explained in the section Management + of Cards and Components, too. + +
+ +
+ 7) Set the PCI driver data and return zero. + + + + + + + + In the above, the chip record is stored. This pointer is + referred in the remove callback and power-management + callbacks, too. + If the card doesn't support the suspend/resume, you can store + the card pointer instead of the chip pointer, so that + snd_card_free can be called directly + without cast in the remove callback. But anyway, be sure + which pointer is used. + +
+
+ +
+ Destructor + + The destructor, remove callback, simply releases the card + instance. Then the ALSA middle layer will release all the + attached components automatically. + + + + It would be typically like the following: + + + +card); + pci_set_drvdata(pci, NULL); + } +]]> + + + + The above code assumes that the chip is allocated + with snd_magic stuff and + has the field to hold the card pointer (see the next + section). + +
+ +
+ Header Files + + For the above example, at least the following include files + are necessary. + + + + + #include + #include + #include + #include + #define SNDRV_GET_ID + #include +]]> + + + + where the last twos are necessary only when module options are + defined in the source file. If the codes are split to several + files, the file without module options don't need them. + + + + In addition to them, you'll need + <linux/interrupt.h> for the interrupt + handling, and <asm/io.h> for the i/o + access. If you use mdelay() or + udelay() functions, you'll need to include + <linux/delay.h>, too. + + + + The ALSA interfaces like PCM or control API are define in other + header files as <sound/xxx.h>. + They have to be included after + <sound/core.h>. + + +
+ + + + + + + + Management of Cards and Components + +
+ Card Instance + + For each soundcard, a card record must be allocated. + + + + A card record is the headquarters of the soundcard. It manages + the list of whole devices (components) on the soundcard, such as + PCM, mixers, MIDI, synthesizer, and so on. Also, the card + record holds the ID and the name strings of the card, manages + the root of proc files, and controls the power-management states + and hotplug disconnections. The component list on the card + record is used to manage the proper releases of resources at + destruction. + + + + As mentioned above, to create a card instance, call + snd_card_new(). + + + + + + + + + + The function takes four arguments, the card-index number, the + id string, the module pointer (usually + THIS_MODULE), + and the size of extra-data space. The last argument is used to + allocate card->private_data for the + chip-specific data. Note that this data + is allocated by + snd_card_new(). + +
+ +
+ Components + + After the card is created, you can attach the components + (devices) to the card instance. On ALSA driver, a component is + represented as a snd_device_t object. + A component can be a PCM instance, a control interface, a raw + MIDI interface, etc. Each of such instances has one component + entry. + + + + A component can be created via + snd_device_new() function. + + + + + + + + + + This takes the card pointer, the device-level + (SNDRV_DEV_XXX), the data pointer, and the + callback pointers (&ops). The + device-level defines the type of components and the order of + registration and de-registration. For most of components, the + device-level is already defined. For a user-defined component, + you can use SNDRV_DEV_LOWLEVEL. + + + + This function itself doesn't allocate the data space. The data + must be allocated manually beforehand, and its pointer is passed + as the argument. This pointer is used as the identifier + (chip in the above example) for the + instance. + + + + Each ALSA pre-defined component such as ac97 or pcm calls + snd_device_new() inside its + constructor. The destructor for each component is defined in the + callback pointers. Hence, you don't need to take care of + calling a destructor for such a component. + + + + If you would like to create your own component, you need to + set the destructor function to dev_free callback in + ops, so that it can be released + automatically via snd_card_free(). The + example will be shown later as an implementation of a + chip-specific data. + +
+ +
+ Chip-Specific Data + + The chip-specific information, e.g. the i/o port address, its + resource pointer, or the irq number, is stored in the + chip-specific record. + Usually, the chip-specific record is typedef'ed as + xxx_t like the following: + + + + + + + + + + You might have objections against such a typedef, but this + typedef is necessary if you use a magic-cast + (explained later). + + + + In general, there are two ways to allocate the chip record. + + +
+ 1. Allocating via <function>snd_card_new()</function>. + + As mentioned above, you can pass the extra-data-length to the 4th argument of snd_card_new(), i.e. + + + + + + + + whether mychip_t is the type of the chip record. + + + + In return, the allocated record can be accessed as + + + +private_data; +]]> + + + + With this method, you don't have to allocate twice. But you + cannot use magic-cast for this record pointer, + instead. + +
+ +
+ 2. Allocating an extra device. + + + After allocating a card instance via + snd_card_new() (with + NULL on the 4th arg), call + snd_magic_kcalloc(). + + + + + + + + Once when the record is allocated via snd_magic stuff, you + can use magic-cast for the void pointer. + + + + The chip record should have the field to hold the card + pointer at least, + + + + + + + + + + Then, set the card pointer in the returned chip instance. + + + +card = card; +]]> + + + + + + Also, you need to define a magic-value for mychip_t. + + + + + + + (the detail will be described in the + + next subsection). + + + + Next, initialize the fields, and register this chip + record as a low-level device with a specified + ops, + + + + + + + + snd_mychip_dev_free() is the + device-destructor function, which will call the real + destructor. + + + + + +device_data, + return -ENXIO); + return snd_mychip_free(chip); + } +]]> + + + + where snd_mychip_free() is the real destructor. + +
+ +
+ Not a magic but a logic + + Now, you might have a question: What is the advantage of the + second method? Obviously, it looks far more complicated. + + As I wrote many times, the second method allows a + magic-cast for mychip_t. If you + have a void pointer (such as + pcm->private_data), the pointer type + is unknown at the compile time, and you cannot know even if a + wrong pointer type is passed. The compiler would accept + it. The magic-cast checks the pointer type at the runtime (and + whether it's a null pointer, too). Hence, the cast will be + much safer and good for debugging. + + + + As you have already seen, allocation with a magic-header can + be done via snd_magic_kmalloc() or + snd_magic_kcalloc(). + + + + + + + + The difference of these two functions is whether the area is + zero-cleared (kcalloc) or not + (kmalloc). + + + + The first argument of the allocator is the type of the + record. The magic-constant has to be defined for this type + beforehand. In this case, we'll need to define + mychip_t_magic, for example, as already + seen, + + + + + + + + The value is arbitrary but should be unique. + This is usually defined in + <include/sndmagic.h> or + <include/amagic.h> for alsa-driver tree, + but you may define it locally in the code at the early + development stage, since changing + sndmagic.h will lead to the recompilation + of the whole driver codes. + + + + The second argument is the extra-data length. It is usually + zero. The third argument is the flags to be passed to kernel + memory allocator, GFP_XXX. Normally, + GFP_KERNEL is passed. + + + + For casting a pointer, use + snd_magic_cast() macro: + + + + + + + + where source_pointer is the pointer to + be casted (e.g. pcm->private_data), and + action is the action to do if the cast + fails (e.g. return -EINVAL). + + + + For releasing the magic-allocated data, you need to call + snd_magic_kfree() function instead of + kfree(). + + + + + + + + + + If you call kfree() for the + magic-allocated value, it will lead to memory leaks. + When the ALSA drivers are compiled with + CONFIG_SND_DEBUG_MEMORY kernel config (or + configured with ), the + non-matching free will be checked and you'll see warning + messages. + + + + If you are 100% sure that your code is bug-free, you can + compile the driver without + CONFIG_SND_DEBUG_MEMORY kernel config, + so that the magic-allocator and the magic-cast will be + replaced to the normal kmalloc and cast. + +
+
+ +
+ Registration and Release + + After all components are assigned, register the card instance + by calling snd_card_register(). The access + to the device files are enabled at this point. That is, before + snd_card_register() is called, the + components are safely inaccessible from external side. If this + call fails, exit the probe function after releasing the card via + snd_card_free(). + + + + For releasing the card instance, you can call simply + snd_card_free(). As already mentioned, all + components are released automatically by this call. + + + + As further notes, the destructors (both + snd_mychip_dev_free and + snd_mychip_free) cannot be defined with + __devexit prefix, because they may be + called from the constructor, too, at the false path. + + + + For a device which allows hotplugging, you can use + snd_card_free_in_thread. This one will + postpone the destruction and wait in a kernel-thread until all + devices are closed. + + +
+ + + + + + + + + PCI Resource Managements + +

+ +
+ Some Hafta's + + The allocation of PCI resources is done in the + probe() function, and usually an extra + xxx_create() function is written for this + purpose. + + + + In the case of PCI devices, you have to call at first + pci_enable_device() function before + allocating resources. Also, you need to set the proper PCI DMA + mask to limit the accessed i/o range. In some cases, you might + need to call pci_set_master() function, + too. + + + + Suppose the 28bit mask, and the code to be added would be like: + + + + + + + +
+ +
+ Resource Allocation + + The allocation of ports and irqs are done via standard kernel + functions. Unlike ALSA ver.0.5.x., there are no helpers for + that. And these resources must be released in the destructor + function (see below). Also, on ALSA 0.9.x, you don't need + allocate (pseudo-)DMA for PCI like 0.5.x. + + + + Now assume that this PCI device has an I/O port with 8 bytes + and an interrupt. Then mychip_t will have the + following fields: + + + + + + + + + + For an i/o port (and also a memory region), you need to have + the resource pointer for the standard resource management. For + an irq, you have to keep only the irq number (integer). But you + need to initialize this number as -1 before actual allocation, + since irq 0 is valid. The port address and its resource pointer + can be initialized as null by + snd_magic_kcalloc() automatically, so you + don't have to take care of it. + + + + The allocation of an i/o port is done like this: + + + +port = pci_resource_start(pci, 0); + if ((chip->res_port = request_region(chip->port, 8, + "My Chip")) == NULL) { + printk(KERN_ERR "cannot allocate the port 0x%lx\n", + chip->port); + snd_mychip_free(chip); + return -EBUSY; + } +]]> + + + + + + It will reserve the i/o port region of 8 bytes of the given + PCI device. The returned value, chip->res_port, is allocated + via kmalloc() by + request_region(). The pointer must be + released via kfree(), but there is some + problem regarding this. This issue will be explained more below. + + + + The allocation of an interrupt source is done like this: + + + +irq, snd_mychip_interrupt, + SA_INTERRUPT|SA_SHIRQ, "My Chip", + (void *)chip)) { + snd_mychip_free(chip); + printk(KERN_ERR "cannot grab irq %d\n", pci->irq); + return -EBUSY; + } + chip->irq = pci->irq; +]]> + + + + where snd_mychip_interrupt() is the + interrupt handler defined later. + Note that chip->irq should be defined + only when request_irq() succeeded. + + + + On the PCI bus, the interrupts can be shared. Thus, + SA_SHIRQ is given as the interrupt flag of + request_irq(). + + + + The last argument of request_irq() is the + data pointer passed to the interrupt handler. Usually, the + chip-specific record is used for that, but you can use what you + like, too. + + + + I won't define the detail of the interrupt handler at this + point, but at least its appearance can be explained now. The + interrupt handler looks usually like the following: + + + + + + + + Again the magic-cast is used here to get the correct pointer + from the second argument. + + + + Now let's write the corresponding destructor for the resources + above. The role of destructor is simple: disable the hardware + (if already activated) and release the resources. So far, we + have no hardware part, so the disabling is not written here. + + + + For releasing the resources, check-and-release + method is a safer way. For the i/o port, do like this: + + + +res_port) { + release_resource(chip->res_port); + kfree_nocheck(chip->res_port); + } +]]> + + + + + + As you can see, the i/o resource pointer is also to be freed + via kfree_nocheck() after + release_resource() is called. You + cannot use kfree() here, because on ALSA, + kfree() may be a wrapper to its own + allocator with the memory debugging. Since the resource pointer + is allocated externally outside the ALSA, it must be released + via the native + kfree(). + kfree_nocheck() is used for that; it calls + the native kfree() without wrapper. + + + + For releasing the interrupt, do like this: + + + +irq >= 0) + free_irq(chip->irq, (void *)chip); +]]> + + + + And finally, release the chip-specific record. + + + + + + + + + + The chip instance is freed via + snd_magic_kfree(). Please use this function + for the object allocated by + snd_magic_kmalloc(). If you free it with + kfree(), it won't work properly and will + result in the memory leak. Also, again, remember that you cannot + set __devexit prefix for this destructor. + + + + We didn't implement the hardware-disabling part in the above. + If you need to do this, please note that the destructor may be + called even before the initialization of the chip is completed. + It would be better to have a flag to skip the hardware-disabling + if the hardware was not initialized yet. + + + + When the chip-data is assigned to the card using + snd_device_new() with + SNDRV_DEV_LOWLELVEL , its destructor is + called at the last. that is, it is assured that all other + components like PCMs and controls have been already released. + You don't have to call stopping PCMs, etc. explicitly, but just + stop the hardware in the low-level. + + + + The management of a memory-mapped region is almost as same as + the management of an i/o port. You'll need three fields like + the following: + + + + + + + + and the allocation would be (assuming its size is 512 bytes): + + + +iobase_phys = pci_resource_start(pci, 0); + chip->iobase_virt = (unsigned long) + ioremap_nocache(chip->iobase_phys, 512); + if ((chip->res_port = request_mem_region(chip->port, 512, + "My Chip")) == NULL) { + printk(KERN_ERR "cannot allocate the memory region\n"); + snd_mychip_free(chip); + return -EBUSY; + } +]]> + + + + and the corresponding destructor would be: + + + +iobase_virt) + iounmap((void *)chip->iobase_virt); + if (chip->res_iobase) { + release_resource(chip->res_iobase); + kfree_nocheck(chip->res_iobase); + } + .... + } +]]> + + + + +

+ PCI Entries + + So far, so good. Let's finish the rest of missing PCI + stuffs. At first, we need a + pci_device_id table for this + chipset. It's a table of PCI vendor/device ID number, and some + masks. + + + + For example, + + + + + + + + + + The first and second fields of + pci_device_id struct are the vendor and + device IDs. If you have nothing special to filter the matching + devices, you can use the rest of fields like above. The last + field of pci_device_id struct is a + private data for this entry. You can specify any value here, for + example, to tell the type of different operations per each + device IDs. Such an example is found in intel8x0 driver. + + + + The last entry of this list is the terminator. You must + specify this all-zero entry. + + + + Then, prepare the pci_driver record: + + + + + + + + + + The probe and + remove functions are what we already + defined in + the previous sections. The remove should + be defined with + __devexit_p() macro, so that it's not + defined for built-in (and non-hot-pluggable) case. The + name + field is the name string of this device. Note that you must not + use a slash / in this string. + + + + And at last, the module entries: + + + + + + + + + + Note that these module entries are tagged with + __init and + __exit prefixes, not + __devinit nor + __devexit. + + + + Oh, one thing was forgotten. If you have no exported symbols, + you need to declare it on 2.2 or 2.4 kernels (on 2.5 kernels + it's not necessary, though). + + + + + + + + That's all! + +
+ + + + + + + + PCM Interface + +
+ General + + The PCM middle layer of ALSA is quite powerful and it is only + necessary for each driver to implement the low-level functions + to access its hardware. + + + + For accessing to the PCM layer, you need to include + <sound/pcm.h> above all. In addition, + <sound/pcm_params.h> might be needed + if you access to some functions related with hw_param. + + + + Each card device can have up to four pcm instances. A pcm + instance corresponds to a pcm device file. The limitation of + number of instances comes only from the available bit size of + the linux's device number. Once when 64bit device number is + used, we'll have more available pcm instances. + + + + A pcm instance consists of pcm playback and capture streams, + and each pcm stream consists of one or more pcm substreams. Some + soundcard supports the multiple-playback function. For example, + emu10k1 has a PCM playback of 32 stereo substreams. In this case, at + each open, a free substream is (usually) automatically chosen + and opened. Meanwhile, when only one substream exists and it was + already opened, the succeeding open will result in the blocking + or the error with EAGAIN according to the + file open mode. But you don't have to know the detail in your + driver. The PCM middle layer will take all such jobs. + +

+ Constructor + + A pcm instance is allocated snd_pcm_new() + function. It would be better to create a constructor for pcm, + namely, + + + +card, "My Chip", 0, 1, 1, + &pcm)) < 0) + return err; + pcm->private_data = chip; + strcpy(pcm->name, "My Chip"); + chip->pcm = pcm; + .... + return 0; + } +]]> + + + + + + The snd_pcm_new() function takes the four + arguments. The first argument is the card pointer to which this + pcm is assigned, and the second is the ID string. + + + + The third argument (index, 0 in the + above) is the index of this new pcm. It begins from zero. When + you will create more than one pcm instances, specify the + different numbers in this argument. For example, + index = 1 for the second PCM device. + + + + The fourth and fifth arguments are the number of substreams + for playback and capture, respectively. Here both 1 are given in + the above example. When no playback or no capture is available, + pass 0 to the corresponding argument. + + + + If a chip supports multiple playbacks or captures, you can + specify more numbers, but they must be handled properly in + open/close, etc. callbacks. When you need to know which + substream you are referring to, then it can be obtained from + snd_pcm_substream_t data passed to each callback + as follows: + + + +number; +]]> + + + + + + After the pcm is created, you need to set operators for each + pcm stream. + + + + + + + + + + The operators are defined typically like this: + + + + + + + + Each of callbacks is explained in the subsection + + Operators. + + + + After setting the operators, most likely you'd like to + pre-allocate the buffer. For the pre-allocation, simply call + the following: + + + +pci, pcm, + 64*1024, 64*1024); +]]> + + + + It will allocate up to 64kB buffer as default. The details of + buffer management will be described in the later section Buffer and Memory + Management. + + + + Additionally, you can set some extra information for this pcm + in pcm->info_flags. + The available values are defined as + SNDRV_PCM_INFO_XXX in + <sound/asound.h>, which is used for + the hardware definition (described later). When your soundchip + supports only half-duplex, specify like this: + + + +info_flags = SNDRV_PCM_INFO_HALF_DUPLEX; +]]> + + + +
+ +
+ ... And the Destructor? + + The destructor for a pcm instance is not always + necessary. Since the pcm device will be released by the middle + layer code automatically, you don't have to call destructor + explicitly. + + + + The destructor would be necessary when you created some + special records internally and need to release them. In such a + case, set the destructor function to + pcm->private_free: + + + PCM Instance with a Destructor + +private_data, return); + // free your own data + kfree(chip->my_private_pcm_data); + // do what you like else... + } + + static int __devinit snd_mychip_new_pcm(mychip_t *chip) + { + snd_pcm_t *pcm; + .... + // allocate your own data + chip->my_private_pcm_data = kmalloc(...); + // set the destructor + pcm->private_data = chip; + pcm->private_free = mychip_pcm_free; + .... + } +]]> + + + +
+ +
+ Operators + + OK, now let me explain the detail of each pcm callback + (ops). In general, every callback must + return 0 if successful, or a negative number with the error + number such as -EINVAL at any + error. + + + + The callback function takes at least the argument with + snd_pcm_substream_t pointer. For retrieving the + chip record from the given substream instance, you can use the + following macro. + + + + + + + + + + It's expanded with a magic-cast, so the cast-error is + automatically checked. You should define chip_t at + the beginning of the code, since this will be referred in many + places of pcm and control interfaces. + + +
+ open callback + + + + + + + + This is called when a pcm substream is opened. + + + + At least, here you have to initialize the runtime hardware + record. Typically, this is done by like this: + + + +runtime; + + runtime->hw = snd_mychip_playback_hw; + return 0; + } +]]> + + + + where snd_mychip_playback_hw is the + pre-defined hardware record. + + + + + + + + + + The similar struct exists on ALSA 0.5.x driver, so you can + guess the values if you already wrote a driver. + + + + The info field contains the type and + capabilities of this pcm. The bit flags are defined in + <sound/asound.h> as + SNDRV_PCM_INFO_XXX. Here, at least, you + have to specify whether the mmap is supported and which + interleaved format is supported. + When the mmap is supported, add + SNDRV_PCM_INFO_MMAP flag here. When the + hardware supports the interleaved or the non-interleaved + format, SNDRV_PCM_INFO_INTERLEAVED or + SNDRV_PCM_INFO_NONINTERLEAVED flag must + be set, respectively. If both are supported, you can set both, + too. + + + + In the above example, MMAP_VALID and + BLOCK_TRANSFER are specified for OSS mmap + mode. Usually both are set. Of course, + MMAP_VALID is set only if the mmap is + really supported. + + + + The other possible flags are + SNDRV_PCM_INFO_PAUSE and + SNDRV_PCM_INFO_RESUME. The + PAUSE bit means that the pcm supports the + pause operation, while the + RESUME bit means that the pcm supports + the suspend/resume operation. If these flags + are set, the trigger callback below + must handle the corresponding commands. + + + + formats field contains the bit-flags + of supported formats (SNDRV_PCM_FMTBIT_XXX). + If the hardware supports more than one format, give all or'ed + bits. In the example above, the signed 16bit little-endian + format is specified. + + + + rates field contains the bit-flags of + supported rates (SNDRV_PCM_RATE_XXX). + When the chip supports continuous rates, pass + CONTINUOUS bit additionally. + The pre-defined rate bits are only for typical rates. If your + chip supports unconventional rates, you need to add + KNOT bit and set up the + constraint manually (explained later). + + + + There have been many changes of terminology between + ALSA 0.5.x and 0.9.x. + On the ALSA 0.9.x world, period means what is + known as fragment in the OSS. It's the least + size of (a part of) the buffer to generate an interrupt. + + + + Now, taking the new terminology into account, the other fields + are self-explanatory (I hope). Please note that here, both + min/max buffer and period sizes are specified in bytes. + + + + Some drivers allocate the private instance for each pcm + substream. It can be stored in + substream->runtime->private_data. + Since it's a void pointer, you + should use magic-kmalloc and magic-cast for such an object. + + + +runtime->private_data = data; + .... + } +]]> + + + + + + The allocated object must be released in the close callback below. + +
+ +
+ close callback + + + + + + + + Obviously, this is called when a pcm substream is closed. + + + + Any private instance for a pcm substream allocated in the + open callback will be released here. + + + +runtime->private_data); + .... + } +]]> + + + +
+ +
+ ioctl callback + + This is used for any special action to pcm ioctls. But + usually you can pass a generic ioctl callback, + snd_pcm_lib_ioctl. + +
+ +
+ hw_params callback + + + + + + + + This and hw_free callbacks exist + only on ALSA 0.9.x. + + + + This is called when the hardware parameter + (hw_params) is set + up by the application, + that is, once when the buffer size, the period size, the + format, etc. are defined for the pcm substream. + + + + Many hardware set-up should be done in this callback, + including the allocation of buffers. + + + + Parameters to be initialized are retrieved by + params_xxx() macros. For allocating a + buffer, you can call a helper function, + + + + + + + + snd_pcm_lib_malloc_pages() is available + only when the DMA buffers have been pre-allocated. + See the section + Buffer Types for more details. + + + + Note that this and prepare callbacks + may be called multiple times per initialization. + For example, the OSS emulation may + call these callbacks at each change via its ioctl. + + + + Thus, you need to take care not to allocate the same buffers + many times, which will lead to memory leak! Calling the + helper function above many times is OK. It will release the + previous buffer automatically when it was already allocated. + + + + Another note is that this callback is non-atomic + (schedulable). This is important, because the + prepare callback + is atomic (non-schedulable). That is, mutex or any + schedule-related functions are available only in + hw_params callback. + Please see the subsection + + Atomicity for details. + +
+ +
+ hw_free callback + + + + + + + + + + This is called to release the resources allocated via + hw_params. For example, releasing the + buffer via + snd_pcm_lib_malloc_pages() is done by + calling the following: + + + + + + + + + + This callback may be called multiple times, too. + Keep track whether the resource was already released. + +
+ +
+ prepare callback + + + + + + + + + + This callback is called when the pcm is + prepared. You can set the format type, sample + rate, etc. here. The difference from + hw_params is that the + prepare callback will be called at each + time + snd_pcm_prepare() is called, i.e. when + recovered after underruns, etc. + + + + As mentioned above, this callback is atomic. + + + + In this and the following callbacks, you can refer to the + values via the runtime record, + substream->runtime. + For example, to get the current + rate, format or channels, access to + runtime->rate, + runtime->format or + runtime->channels, respectively. + The physical address of the allocated buffer is set to + runtime->dma_area. The buffer and period sizes are + in runtime->buffer_size and runtime->period_size, + respectively. + + + + Note that the period and the buffer sizes are stored in + frames. In the ALSA world, 1 frame = channels + * samples-size. For conversion between frames and bytes, you + can use the helper functions, + frames_to_bytes() and + bytes_to_frames(). + + + +period_size); +]]> + + + + + + Be careful that this callback will be called many times at + each set up, too. + +
+ +
+ trigger callback + + + + + + + + This is called when the pcm is started, stopped or paused. + + + + Which action is specified in the second argument, + SNDRV_PCM_TRIGGER_XXX in + <sound/pcm.h>. At least, + START and STOP + commands must be defined in this callback. + + + + + + + + + + When the pcm supports the pause operation (given in info + field of the hardware table), PAUSE_PUSE + and PAUSE_RELEASE commands must be + handled here, too. The former is the command to pause the pcm, + and the latter to restart the pcm again. + + + + When the pcm supports the suspend/resume operation, + SUSPEND and RESUME + commands must be handled, too. Obviously it does suspend and + resume of the pcm substream. Usually, the + SUSPEND is identical with + STOP command and the + RESUME is identical with + START command. + + + + This callback is also atomic. + +
+ +
+ pointer callback + + + + + + + + This callback is called when the PCM middle layer inquires + the current hardware position on the buffer. The position must + be returned in frames (which was in bytes on ALSA 0.5.x), + ranged from 0 to buffer_size - 1. + + + + This is called usually from the buffer-update routine in the + pcm middle layer, which is invoked when + snd_pcm_period_elapsed() is called in the + interrupt routine. Then the pcm middle layer updates the + position and calculates the available space, and wakes up the + sleeping poll threads, etc. + + + + This callback is also atomic. + +
+ +
+ copy and silence callbacks + + These callbacks are not mandatory, and can be omitted in + most cases. These callbacks are used when the hardware buffer + cannot be on the normal memory space. Some chips have their + own buffer on the hardware which is not mappable. In such a + case, you have to transfer the data manually from the memory + buffer to the hardware buffer. Or, if the buffer is + non-contiguous on both physical and virtual memory spaces, + these callbacks must be defined, too. + + + + If these two callbacks are defined, copy and set-silence + operations are done by them. The detailed will be described in + the later section Buffer and Memory + Management. + +
+ +
+ page callback + + + This callback is also not mandatory. This callback is used + mainly for the non-contiguous buffer. The mmap calls this + callback to get the page address. Some examples will be + explained in the later section Buffer and Memory + Management, too. + +
+
+ +
+ Interrupt Handler + + The rest of pcm stuff is the PCM interrupt handler. The + role of PCM interrupt handler in the sound driver is to update + the buffer position and to tell the PCM middle layer when the + buffer position goes across the prescribed period size. To + inform this, call snd_pcm_period_elapsed() + function. + + + + There are several types of sound chips to generate the interrupts. + + +
+ Interrupts at the period (fragment) boundary + + This is the most frequently found type: the hardware + generates an interrupt at each period boundary. + In this case, you can call + snd_pcm_period_elapsed() at each + interrupt. + + + + snd_pcm_period_elapsed() takes the + substream pointer as its argument. Thus, you need to keep the + substream pointer accessible from the chip instance. For + example, define substream field in the chip record to hold the + current running substream pointer, and set the pointer value + at open callback (and reset at close callback). + + + + If you aquire a spinlock in the interrupt handler, and the + lock is used in other pcm callbacks, too, then you have to + release the lock before calling + snd_pcm_period_elapsed(), because + snd_pcm_period_elapsed() calls other pcm + callbacks inside. + + + + A typical coding would be like: + + + Interrupt Handler Case #1 + +lock); + .... + if (pcm_irq_invoked(chip)) { + // call updater, unlock before it + spin_unlock(&chip->lock); + snd_pcm_period_elapsed(chip->substream); + spin_lock(&chip->lock); + } + .... + spin_unlock(&chip->lock); + } +]]> + + + +
+ +
+ High-frequent timer interrupts + + This is the case when the hardware doesn't generate interrupts + at the period boundary but do timer-interrupts at the fixed + timer rate (e.g. es1968 or ymfpci drivers). + In this case, you need to check the current hardware + position and accumulates the processed sample length at each + interrupt. When the accumulated size overcomes the period + size, call + snd_pcm_period_elapsed() and reset the + accumulator. + + + + A typical coding would be like the following. + + + Interrupt Handler Case #2 + +lock); + .... + if (pcm_irq_invoked(chip)) { + unsigned int last_ptr, size; + // get the current hardware pointer (in frames) + last_ptr = get_hw_ptr(chip); + // calculate the processed frames since the + // last update + if (last_ptr < chip->last_ptr) + size = runtime->buffer_size + last_ptr + - chip->last_ptr; + else + size = last_ptr - chip->last_ptr; + // remember the last updated point + chip->last_ptr = last_ptr; + // accumulate the size + chip->size += size; + // over the period boundary? + if (chip->size >= runtime->period_size) { + // reset the accumulator + chip->size %= runtime->period_size; + // call updater + spin_unlock(&chip->lock); + snd_pcm_period_elapsed(substream); + spin_lock(&chip->lock); + } + } + .... + spin_unlock(&chip->lock); + } +]]> + + + +
+ +
+ On calling <function>snd_pcm_period_elapsed()</function> + + In both cases, even if more than one period are elapsed, you + don't have to call + snd_pcm_period_elapsed() many times. Call + only once. And the pcm layer will check the current hardware + pointer and update to the latest status. + +
+
+ +
+ Atomicity + + One of the most important (and thus difficult to debug) problem + on the kernel programming is the race condition. + On linux kernel, usually it's solved via spin-locks or + semaphores. In general, if the race condition may + happen in the interrupt handler, it's handled as atomic, and you + have to use spinlock for protecting the critical session. If it + never happens in the interrupt and it may take relatively long + time, you should use semaphore. + + + + As already seen, some pcm callbacks are atomic and some are + not. For example, hw_params callback is + non-atomic, while prepare callback is + atomic. This means, the latter is called already in a spinlock + held by the PCM middle layer. Please take this atomicity into + account when you use a spinlock or a semaphore in the callbacks. + + + + In the atomic callbacks, you cannot use functions which may call + schedule or go to + sleep. The semaphore and mutex do sleep, + and hence they cannot be used inside the atomic callbacks + (e.g. prepare callback). + For taking a certain delay in such a callback, please use + udelay() or mdelay(). + + + + This atomicity problem appears also in the initialization of the + hardware when the power-management is supported. The functions + for suspending and resuming the chip must be atomic, i.e. no + mutex nor sleep can be used in them. + + +
+
+ Constraints + + If your chip supports unconventional sample rates, or only the + limited samples, you need to set a constraint for the + condition. + + + + For example, in order to restrict the sample rates in the some + supported values, use + snd_pcm_hw_constraint_list(). + You need to call this function in the open callback. + + + Example of Hardware Constraints + +runtime, 0, + SNDRV_PCM_HW_PARAM_RATE, + &constraints_rates); + if (err < 0) + return err; + .... + } +]]> + + + + + + There are many different constraints. You can even define your + own constraint rules. I won't explain the details here, rather I + would like to say, Luke, use the source. + +
+ + + + + + + + + Control Interface + +
+ General + + The control interface is used widely for many switches, + sliders, etc. which are accessed from the user-space. Its most + important use is the mixer interface. In other words, on ALSA + 0.9.x, all the mixer stuff is implemented on the control kernel + API (while there was an independent mixer kernel API on 0.5.x). + + + + ALSA has a well-defined AC97 control module. If your chip + supports only the AC97 and nothing else, you can skip this + section. + + + + The control API is defined in + <sound/control.h>. + Include this file if you add your own controls. + +
+ +
+ Definition of Controls + + For creating a new control, you need to define the three + callbacks: info, + get and + put. Then, define a + snd_kcontrol_new_t record, such as: + + + Definition of a Control + + + + + + + + Most likely the control is created via + snd_ctl_new1(), and in such a case, you can + add __devinitdata prefix to the + definition like above. + + + + The iface field specifies the type of + the control, + SNDRV_CTL_ELEM_IFACE_XXX. There are + MIXER, PCM, + CARD, etc. + + + + The name is the name identifier + string. On ALSA 0.9.x, the control name is very important, + because its role is classified from its name. There are + pre-defined standard control names. The details are described in + the subsection + + Control Names. + + + + The index field holds the index number + of this control. If there are several different controls with + the same name, they can be distinguished by the index + number. This is the case when + several codecs exist on the card. If the index is zero, you can + omit the definition above. + + + + The access field contains the access + type of this control. Give the combination of bit masks, + SNDRV_CTL_ELEM_ACCESS_XXX, there. + The detailed will be explained in the subsection + + Access Flags. + + + + The private_values field contains + an arbitrary long integer value for this record. When using + generic info, + get and + put callbacks, you can pass a value + through this field. If several small numbers are necessary, you can + combine them in bitwise. Or, it's possible to give a pointer + (casted to unsigned long) of some record to this field, too. + + + + The other three are + + callback functions. + +
+ +
+ Control Names + + There are some standards for defining the control names. A + control is usually defined from the three parts as + SOURCE DIRECTION FUNCTION. + + + + The first, SOURCE, specifies the source + of the control, and is a string such as Master, + PCM, CD or + Line. There are many pre-defined sources. + + + + The second, DIRECTION, is one of the + following strings according to the direction of the control: + Playback, Capture, Bypass + Playback and Bypass Capture. Or, it can + be omitted, meaning both playback and capture directions. + + + + The third, FUNCTION, is one of the + following strings according to the function of the control: + Switch, Volume and + Route. + + + + The example of control names are, thus, Master Capture + Switch or PCM Playback Volume. + + + + There are some exceptions: + + +
+ Global capture and playback + + Capture Source, Capture Switch + and Capture Volume are used for the global + capture (input) source, switch and volume. Similarly, + Playback Switch and Playback + Volume are used for the global output gain switch and + volume. + +
+ +
+ Tone-controls + + tone-control switch and volumes are specified like + Tone Control - XXX, e.g. Tone Control - + Switch, Tone Control - Bass, + Tone Control - Center. + +
+ +
+ 3D controls + + 3D-control switches and volumes are specified like 3D + Control - XXX, e.g. 3D Control - + Switch, 3D Control - Center, 3D + Control - Space. + +
+ +
+ Mic boost + + Mic-boost switch is set as Mic Boost or + Mic Boost (6dB). + + + + More precise information can be found in + alsa-kernel/Documentation/ControlNames.txt. + +
+
+ +
+ Access Flags + + + The access flag is the bit-flags which specifies the access type + of the given control. The default access type is + SNDRV_CTL_ELEM_ACCESS_READWRITE, + which means both read and write are allowed to this control. + When the access flag is omitted (i.e. = 0), it is + regarded as READWRITE access as default. + + + + When the control is read-only, pass + SNDRV_CTL_ELEM_ACCESS_READ instead. + In this case, you don't have to define + put callback. + Similarly, when the control is write-only (although it's a rare + case), you can use WRITE flag instead, and + you don't need get callback. + + + + If the control value changes frequently (e.g. the VU meter), + VOLATILE flag should be given. This means + that the control may be changed without + + notification. Applications should poll such + a control constantly. + + + + When the control is inactive, set + INACTIVE flag, too. + There are LOCK and + OWNER flags for changing the write + permissions. + + +
+ +
+ Callbacks + +
+ info callback + + The info callback is used to get + the detailed information of this control. This must store the + values of the given snd_ctl_elem_info_t + object. For example, for a boolean control with a single + element will be: + + + Example of info callback + +type = SNDRV_CTL_ELEM_TYPE_BOOLEAN; + uinfo->count = 1; + uinfo->value.integer.min = 0; + uinfo->value.integer.max = 1; + return 0; + } +]]> + + + + + + The type field specifies the type + of the control. There are BOOLEAN, + INTEGER, ENUMERATED, + BYTES, IEC958 and + INTEGER64. The + count field specifies the + number of elements in this control. For example, a stereo + volume would have count = 2. The + value field is a union, and + the values stored are depending on the type. The boolean and + integer are identical. + + + + The enumerated type is a bit different from others. You'll + need to set the string for the currently given item index. + + + +value.enumerated.items = 4; + if (uinfo->value.enumerated.item > 3) + uinfo->value.enumerated.item = 3; + strcpy(uinfo->value.enumerated.name, + texts[uinfo->value.enumerated.item]); +]]> + + + +
+ +
+ get callback + + + This callback is used to read the current value of the + control and to return to the user-space. + + + + For example, + + + Example of get callback + +value.integer.value[0] = get_some_value(chip); + return 0; + } +]]> + + + + + + Here, the chip instance is retrieved via + snd_kcontrol_chip() macro. This macro + converts from kcontrol->private_data to the type defined by + chip_t. The + kcontrol->private_data field is + given as the argument of snd_ctl_new() + (see the later subsection + Constructor). + + + + The value field is depending on + the type of control as well as on info callback. For example, + the sb driver uses this field to store the register offset, + the bit-shift and the bit-mask. The + private_value is set like + + + + + + and is retrieved in callbacks like + + +private_value & 0xff; + int shift = (kcontrol->private_value >> 16) & 0xff; + int mask = (kcontrol->private_value >> 24) & 0xff; + .... + } +]]> + + + + + + In get callback, you have to fill all the elements if the + control has more than one elements, + i.e. count > 1. + In the example above, we filled only one element + (value.integer.value[0]) since it's + assumed as count = 1. + +
+ +
+ put callback + + + This callback is used to write a value from the user-space. + + + + For example, + + + Example of put callback + +current_value != + ucontrol->value.integer.value[0]) { + change_current_value(chip, + ucontrol->value.integer.value[0]); + changed = 1; + } + return changed; + } +]]> + + + + As seen above, you have to return 1 if the value is + changed. If the value is not changed, return 0 instead. + If any fatal error happens, return a negative error code as + usual. + + + + Like get callback, + when the control has more than one elements, + all elemehts must be evaluated in this callback, too. + +
+ +
+ Callbacks are not atomic + + All these three callbacks are basically not atomic. + +
+
+ +
+ Constructor + + When everything is ready, finally we can create a new + control. For creating a control, there are two functions to be + called, snd_ctl_new1() and + snd_ctl_add(). + + + + In the simplest way, you can do like this: + + + + + + + + where my_control is the + snd_kcontrol_new_t object defined above, and chip + is the object pointer to be passed to + kcontrol->private_data + which can be referred in callbacks. + + + + snd_ctl_new1() allocates a new + snd_kcontrol_t instance (that's why the definition + of my_control can be with + __devinitdata + prefix), and snd_ctl_add assigns the given + control component to the card. + +
+ +
+ Change Notification + + If you need to change and update a control in the interrupt + routine, you can call snd_ctl_notify(). For + example, + + + + + + + + This function takes the card pointer, the event-mask, and the + control id pointer for the notification. The event-mask + specifies the types of notification, for example, in the above + example, the change of control values is notified. + The id pointer is the pointer of snd_ctl_elem_id_t + to be notified. + You can find some examples in es1938.c or + es1968.c for hardware volume interrupts. + +
+ + + + + + + + + API for AC97 Codec + +
+ General + + The ALSA AC97 codec layer is a well-defined one, and you don't + have to write many codes to control it. Only low-level control + routines are necessary. The AC97 codec API is defined in + <sound/ac97_codec.h>. + +
+ +
+ Full Code Example + + + Example of AC97 Interface + +private_data, return 0); + .... + // read a register value here from the codec + return the_register_value; + } + + static void snd_mychip_ac97_write(ac97_t *ac97, + unsigned short reg, unsigned short val) + { + mychip_t *chip = snd_magic_cast(mychip_t, + ac97->private_data, return 0); + .... + // write the given register value to the codec + } + + static int snd_mychip_ac97(mychip_t *chip) + { + ac97_t ac97; + + memset(&ac97, 0, sizeof(ac97)); + ac97.write = snd_mychip_ac97_write; + ac97.read = snd_mychip_ac97_read; + ac97.private_data = chip; + return snd_ac97_mixer(card, &ac97, &chip->ac97); + } + +]]> + + + +
+ +
+ Constructor + + For creating an ac97 instance, call + snd_ac97_mixer() with an ac97_t + record, in which the callbacks and the private_data is set. + + + +ac97); +]]> + + + + where chip->ac97 is the pointer of a newly created + ac97_t instance. + This instance is not necessarily stored in the chip + record. When you need to change the register values from the + driver, or need the suspend/resume of ac97 codecs, keep this + pointer to pass to the corresponding functions. + +
+ +
+ Callbacks + + The standard callbacks are read and + write. Obviously they + correspond to the functions for read and write accesses to the + hardware low-level codes. + + + + The read callback returns the + register value specified in the argument. + + + +private_data, return 0); + .... + return the_register_value; + } +]]> + + + + Here, the chip can be cast from ac97->private_data. + + + + Meanwhile, the write callback is + used to set the register value. + + + + + + + + + + These callbacks are non-atomic like the callbacks of control API + unless they are called during suspend/resume phase. + + + + There are also other callbacks: + reset, + wait and + init. + + + + The reset callback is used to reset + the codec. If the chip requires a special way of reset, you can + define this callback. + This callback must be atomic when it's called in the suspend + mode. + + + + The wait callback is used for a + certain wait at the standard initialization of the codec. If the + chip requires the extra wait-time, define this callback. + This callback is always non-atomic, because it's never called + in the resume mode. + + + + The init callback is used for + additional initialization of the codec. This callback is called + after the reset, and should be atomic in the resume mode. + +
+ +
+ Updating Registers in The Driver + + If you need to access to the codec from the driver, you can + call the following functions: + snd_ac97_write(), + snd_ac97_read(), + snd_ac97_update() and + snd_ac97_update_bits(). + + + + Both snd_ac97_write() and + snd_ac97_update() functions are used to + set a value to the given register + (AC97_XXX). The different between them is + that snd_ac97_update() doesn't write a + value if the given value has been already set, while + snd_ac97_write() always rewrites the + value. + + + + + + + + + + snd_ac97_read() is used to read the value + of the given register. For example, + + + + + + + + + + snd_ac97_update_bits() is used to update + some bits of the given register. + + + + + + + + + + Also, there is a function to change the sample rate (of a + certain register such as + AC97_PCM_FRONT_DAC_RATE) when VRA is + supported by the codec: + snd_ac97_set_rate(). + + + + + + + + + + The following registers are available for setting the rate: + AC97_PCM_MIC_ADC_RATE, + AC97_PCM_FRONT_DAC_RATE, + AC97_PCM_LR_ADC_RATE, + AC97_SPDIF. When the + AC97_SPDIF is specified, the register is + not really changed but the corresponding IEC958 status bits will + be updated. + +
+ +
+ Clock Adjustment + + On some chip, the clock of the codec isn't 48000 but using a + PCI clock (to save a quartz!). In this case, change the field + ac97->clock to the corresponding + value. For example, intel8x0 + and es1968 drivers have the auto-measurement function of the + clock. + +
+ +
+ Proc Files + + The ALSA AC97 interface will create a proc file such as + /proc/asound/card0/ac97#0 and + ac97#0regs. You can refer to these files to + see the current status and registers of the codec. + +
+ +
+ Multiple Codecs + + When there are several codecs on the same card, you need to + call snd_ac97_new() multiple times with + ac97.num=1 or greater. The num field + specifies the codec + number. + + + + If you have set up multiple codecs, you need to either write + different callbacks for each codec or check + ac97->num in the + callback routines. + +
+ + + + + + + + + MIDI (MPU401-UART) Interface + +
+ General + + Many soundcards have built-in MIDI (MPU401-UART) + interfaces. When the soundcard supports the standard MPU401-UART + interface, most likely you can use the ALSA MPU401-UART API. The + MPU401-UART API is defined in + <sound/mpu401.h>. + + + + Some soundchips have similar but a little bit different + implementation of mpu401 stuff. For example, emu10k1 has its own + mpu401 routines. + + + + In this document, I won't explain the rawmidi interface API, + which is the basis of MPU401-UART implementation. + + + + For details, please check the source, + core/rawmidi.c, and examples such as + drivers/mpu401/mpu401_uart.c or + usb/usbmidi.c. + +
+ +
+ Constructor + + For creating a rawmidi object, call + snd_mpu401_uart_new(). + + + + + + + + + + The first argument is the card pointer, and the second is the + index of this component. You can create up to 8 rawmidi + devices. + + + + The third argument is the type of the hardware, + MPU401_HW_XXX. If it's not a special one, + you can use MPU401_HW_MPU401. + + + + The 4th argument is the i/o port address. Many + backward-compatible MPU401 has an i/o port such as 0x330. Or, it + might be a part of its own PCI i/o region. It depends on the + chip design. + + + + When the i/o port address above is a part of the PCI i/o + region, the MPU401 i/o port might have been already allocated + (reserved) by the driver itself. In such a case, pass non-zero + to the 5th argument + (integrated). Otherwise, pass 0 to it, + and + the mpu401-uart layer will allocate the i/o ports by itself. + + + + Usually, the port address corresponds to the command port and + port + 1 corresponds to the data port. If not, you may change + the cport field of + mpu401_t manually + afterward. However, mpu401_t pointer is not + returned explicitly by + snd_mpu401_uart_new(). You need to cast + rmidi->private_data to + mpu401_t explicitly, + + + +private_data, ); +]]> + + + + and reset the cport as you like: + + + +cport = my_own_control_port; +]]> + + + + + + The 6th argument specifies the irq number for UART. If the irq + is already allocated, pass 0 to the 7th argument + (irq_flags). Otherwise, pass the flags + for irq allocation + (SA_XXX bits) to it, and the irq will be + reserved by the mpu401-uart layer. If the card doesn't generates + UART interrupts, pass -1 as the irq number. Then a timer + interrupt will be invoked for polling. + +
+ +
+ Interrupt Handler + + When the interrupt is allocated in + snd_mpu401_uart_new(), the private + interrupt handler is used, hence you don't have to do nothing + else than creating the mpu401 stuff. Otherwise, you have to call + snd_mpu401_uart_interrupt() explicitly when + a UART interrupt is invoked and checked in your own interrupt + handler. + + + + In this case, you need to pass the private_data of the + returned rawmidi object from + snd_mpu401_uart_new() as the second + argument of snd_mpu401_uart_interrupt(). + + + +private_data, regs); +]]> + + + +
+ + + + + + + + + Miscellaneous Devices + +
+ FM OPL3 + + The FM OPL3 is still used on many chips (mainly for backward + compatibility). ALSA has a nice OPL3 FM control layer, too. The + OPL3 API is defined in + <sound/opl3.h>. + + + + FM registers can be directly accessed through direct-FM API, + defined in <sound/asound_fm.h>. In + ALSA native mode, FM registers are accessed through + Hardware-Dependant Device direct-FM extension API, whereas in + OSS compatible mode, FM registers can be accessed with OSS + direct-FM compatible API on /dev/dmfmX device. + + + + For creating the OPL3 component, you have two functions to + call. The first one is a constructor for opl3_t + instance. + + + + + + + + + + The first argument is the card pointer, the second one is the + left port address, and the third is the right port address. In + most cases, the right port is placed at the left port + 2. + + + + The fourth argument is the hardware type. + + + + When the left and right ports have been already allocated by + the card driver, pass non-zero to the fifth argument + (integrated). Otherwise, opl3 module will + allocate the specified ports by itself. + + + + If this function returns successfully with 0, then create a + hwdep device for this opl3. + + + + + + + + + + The first argument is the opl3_t instance you + created, and the second is the index number, usually 0. + + + + The third argument is the index-offset for the sequencer + client assigned to the OPL3 port. When there is an MPU401-UART, + give 1 for here (UART always takes 0). + +
+ +
+ Hardware-Dependent Devices + + Some chips need the access from the user-space for special + controls or for loading the micro code. In such a case, you can + create a hwdep (hardware-dependent) device. The hwdep API is + defined in <sound/hwdep.h>. You can + find examples in opl3 driver or + isa/sb/sb16_csp.c. + + + + Creation of the hwdep instance is done via + snd_hwdep_new(). + + + + + + + + where the third argument is the index number. + + + + You can then pass any pointer value to the + private_data. Again, it should be a + magic-allocated record, so that the cast can be checked more + safely. If you assign a private data, you should define the + destructor, too. The destructor function is set to + private_free field. + + + +private_data = p; + hw->private_free = mydata_free; +]]> + + + + and the implementation of destructor would be: + + + +private_data, return); + snd_magic_kfree(p); + } +]]> + + + + + + The arbitrary file operations can be defined for this + instance. The file operators are defined in + ops table. For example, assume that + this chip needs an ioctl. + + + +ops.open = mydata_open; + hw->ops.ioctl = mydata_ioctl; + hw->ops.release = mydata_release; +]]> + + + + And implement the callback functions as you like. + +
+ +
+ IEC958 (S/PDIF) + + Usually the controls for IEC958 devices are implemented via + control interface. There is a macro to compose a name string for + IEC958 controls, SNDRV_CTL_NAME_IEC958() + defined in <include/asound.h>. + + + + There are some standard controls for IEC958 status bits. These + controls use the type SNDRV_CTL_ELEM_TYPE_IEC958, + and the size of element is fixed as 4 bytes array + (value.iec958.status[x]). For info + callback, you don't specify + the value field for this type (the count field must be set, + though). + + + + IEC958 Playback Con Mask is used to return the + bit-mask for the IEC958 status bits of consumer mode. Similarly, + IEC958 Playback Pro Mask returns the bitmask for + professional mode. They are read-only controls, and are defined + as MIXER controls (iface = + SNDRV_CTL_ELEM_IFACE_MIXER). + + + + Meanwhile, IEC958 Playback Default control is + defined for getting and setting the current default IEC958 + bits. Note that this one is usually defined as a PCM control + (iface = SNDRV_CTL_ELEM_IFACE_PCM), + although in some places it's defined as a MIXER control. + + + + In addition, you can define the control switches to + enable/disable or to set the raw bit mode. The implementation + will depend on the chip, but the control should be named as + IEC958 xxx, preferably using + SNDRV_CTL_NAME_IEC958() macro. + + + + You can find several cases, for example, + pci/emu10k1, + pci/ice1712, or + pci/cmipci.c. + +
+ + + + + + + + + Buffer and Memory Management + +
+ Buffer Types + + ALSA provides several different buffer allocation functions + depending on the bus and the architecture. All these have a + consistent API. The allocation of physically-contiguous pages is + done via + snd_malloc_xxx_pages() function, where xxx + is the bus type. + + + + The allocation of pages with fallback is + snd_malloc_xxx_pages_fallback(). This + function tries to allocate the specified pages but if the pages + are not available, it tries to reduce the page sizes until the + enough space is found. + + + + For releasing the space, call + snd_free_xxx_pages() function. + + + + Usually, ALSA drivers try to allocate and reserve + a large contiguous physical space + at the time the module is loaded for the later use. + This is called pre-allocation. + As already written, you can call the following function at the + construction of pcm instance (in the case of PCI bus). + + + + + + + + where size is the byte size to be + pre-allocated and the max is the maximal + size to be changed via prealloc proc file. + The allocator will try to get as the large area as possible + within the given size. + There are different versions of pre-allocator for different + buses. + + + + Once when the buffer is pre-allocated, you can use the + allocator in the hw_params callback + + + + + + + + Note that you have to pre-allocate to use this function + (i.e. you cannot use this function for + + a scatter-gather buffer). + +
+ +
+ External Hardware Buffers + + Some chips have their own hardware buffers and the DMA + transfer from the host memory is not available. In such a case, + you need to either 1) copy/set the audio data directly to the + external hardware buffer, or 2) make an intermediate buffer and + copy/set the data from it to the external hardware buffer in + interrupts (or in tasklets, preferably). + + + + The first case works fine if the external hardware buffer is enough + large. This method doesn't need any extra buffers and thus is + more effective. You need to define the + copy and + silence callbacks for + the data transfer. However, there is a drawback: it cannot + be mmapped. The examples are GUS's GF1 PCM or emu8000's + wavetable PCM. + + + + The second case allows the mmap of the buffer, although you have + to handle an interrupt or a tasklet for transferring the data + from the intermediate buffer to the hardware buffer. You can find an + example in vxpocket driver. + + + + Another case is that the chip uses a PCI memory-map + region for the buffer instead of the host memory. In this case, + mmap is available only on certain architectures like intel. In + non-mmap mode, the data cannot be transferred as the normal + way. Thus you need to define copy and + silence callbacks as well + as in the cases above. The examples are found in + rme32.c and rme96.c. + + + + The implementation of copy and + silence callbacks depends upon + whether the hardware supports interleaved or non-interleaved + samples. The copy callback is + defined like below, a bit + differently depending whether the direction is playback or + capture: + + + + + + + + + + In the case of interleaved samples, the second argument + (channel) is not used. The third argument + (pos) points the + current position offset in frames. + + + + The meaning of the fourth argument is different between + playback and capture. For playback, it holds the source data + pointer, and for capture, it's the destination data pointer. + + + + The last argument is the number of frames to be copied. + + + + What you have to do in this callback is again different + between playback and capture directions. In the case of + playback, you do: copy the given amount of data + (count) at the specified pointer + (src) to the specified offset + (pos) on the hardware buffer. When + coded like memcpy-like way, the copy would be like: + + + + + + + + + + For the capture direction, you do: copy the given amount of + data (count) at the specified offset + (pos) on the hardware buffer to the + specified pointer (dst). + + + + + + + + Note that both of the position and the data amount are given + in frames. + + + + In the case of non-interleaved samples, the implementation + will be a bit more complicated. + + + + You need to check the channel argument, and if it's -1, copy + the whole channels. Otherwise, you have to copy only the + specified channel. Please check + isa/gus/gus_pcm.c as an example. + + + + The silence callback is also + implemented in a similar way. + + + + + + + + + + The meanings of arguments are identical with the + copy + callback, although there is no src/dst + argument. In the case of interleaved samples, the channel + argument has no meaning, as well as on + copy callback. + + + + The role of silence callback is to + set the given amount + (count) of silence data at the + specified offset (pos) on the hardware + buffer. Suppose that the data format is signed (that is, the + silent-data is 0), and the implementation using a memset-like + function would be like: + + + + + + + + + + In the case of non-interleaved samples, again, the + implementation becomes a bit more complicated. See, for example, + isa/gus/gus_pcm.c. + +
+ +
+ Non-Contiguous Buffers + + If your hardware supports the page table like emu10k1 or the + buffer descriptors like via82xx, you can use the scatter-gather + (SG) DMA. ALSA provides an interface for handling SG-buffers. + The API is provided in <sound/pcm_sgbuf.h>. + + + + For creating the SG-buffer handler, call + snd_pcm_lib_preallocate_sg_pages() or + snd_pcm_lib_preallocate_sg_pages_for_all() + in the PCM constructor like other PCI pre-allocator. + You need to pass the + pci_dev struct pointer of the chip. + The snd_sg_buf_t instance is created as + substream->dma_private. You can cast + the pointer like: + + + +dma_private, return -EINVAL); +]]> + + + + + + Then call snd_pcm_lib_malloc_pages() + in hw_params callback + as well as in the case of normal PCI buffer. + The SG-buffer handler will allocate the non-contiguous kernel + pages of the given size and map them onto the virtually contiguous + memory. The virtual pointer is addressed in runtime->dma_area. + The physical address (runtime->dma_addr) is set to zero, + because the buffer is physically non-contigous. + The physical address table is set up in sgbuf->table. + You can get the physical address at a certain offset via + snd_pcm_sgbuf_get_addr(). + + + + When a SG-handler is used, you need to set + snd_pcm_sgbuf_ops_page as + the page callback. + + + + For releasing the data, call + snd_pcm_lib_free_pages() in the + hw_free callback as usual. + +
+ +
+ Vmalloc'ed Buffers + + It's possible to use a buffer allocated via + vmalloc, for example, for an intermediate + buffer. Since the allocated pages are not contiguous, you need + to set the page callback to obtain + the physical address at every offset. + + + + The implementation of page callback + would be like this: + + + + + + /* get the physical page pointer on the given offset */ + static struct page *mychip_page(snd_pcm_substream_t *substream, + unsigned long offset) + { + void *pageptr = substream->runtime->dma_area + offset; + return vmalloc_to_page(pageptr); + } +]]> + + + +
+ + + + + + + + + Proc Interface + + ALSA provides an easy interface for procfs. The proc files are + very useful for debugging. I recommend you set up proc files if + you write a driver and want to get a running status or register + dumps. The API is found in + <sound/info.h>. + + + + For creating a proc file, call + snd_card_proc_new(). + + + + + + + + where the second argument specifies the proc-file name to be + created. The above example will create a file + my-file under the card directory, + e.g. /proc/asound/card0/my-file. + + + + Like other components, the proc entry created via + snd_card_proc_new() will be registered and + released automatically in the card registration and release + functions. + + + + When the creation is successful, the function stores a new + instance at the pointer given in the third argument. + It is initialized as a text proc file for read only. For using + this proc file as a read-only text file as it is, set the read + callback with a private data via + snd_info_set_text_ops(). + + + + + + + + where the second argument (chip) is the + private data to be used in the callbacks and the third + (my_proc_read) is the callback function, which + is defined like + + + + + + + + + + + In the read callback, use snd_iprintf() for + output strings, which works just like normal + printf(). For example, + + + +private_data, return); + + snd_iprintf(buffer, "This is my chip!\n"); + snd_iprintf(buffer, "Port = %ld\n", chip->port); + } +]]> + + + + + + The file permission can be changed afterwards. As default, it's + set as read only for all users. If you want to add the write + permission to the user (root as default), set like below: + + + +mode = S_IFREG | S_IRUGO | S_IWUSR; +]]> + + + + and set the write buffer size and the callback + + + +c.text.write_size = 256; + entry->c.text.write = my_proc_write; +]]> + + + + + + The buffer size for read is set to 1024 implicitly by + snd_info_set_text_ops(). It should suffice + in most cases (the size will be aligned to + PAGE_SIZE anyway), but if you need to handle + very large text files, you can set it explicitly, too. + + + +c.text.read_size = 65536; +]]> + + + + + + For the write callback, you can use + snd_info_get_line() to get a text line, and + snd_info_get_str() to retrieve a string from + the line. Some examples are found in + core/oss/mixer_oss.c, core/oss/and + pcm_oss.c. + + + + For a raw-data proc-file, set the attributes like the following: + + + +content = SNDRV_INFO_CONTENT_DATA; + entry->private_data = chip; + entry->c.ops = &my_file_io_ops; + entry->size = 4096; + entry->mode = S_IFREG | S_IRUGO; +]]> + + + + + + The callback is much more complicated than the text-file + version. You need to use a low-level i/o functions such as + copy_from/to_user() to transfer the + data. Also, you have to keep tracking the file position, too. + + + +f_pos + size > local_max_size) + size = local_max_size - file->f_pos; + if (copy_to_user(buf, local_data + file->f_pos, size)) + return -EFAULT; + file->f_pos += size; + return size; + } +]]> + + + + + + + + + + + + Power Management + + If the chip is supposed to work with with suspend/resume + functions, you need to add the power-management codes to the + driver. The additional codes for the power-management should be + ifdef'ed with + CONFIG_PM. + + + + Basic jobs of suspend/resume are done in + suspend and + resume callbacks of + pci_driver struct. Unfortunately, the + API of these callbacks was changed at the middle time of Linux + 2.4.x, if you want to keep the support for older kernels, you + have to write two different callbacks. The example below is the + skeleton callbacks which just call the real suspend and resume + functions. + + + + + + + + + + The scheme of the real suspend job is as following. + + + Check whether the power-state is already D3hot. If yes, skip the job. + Call snd_pcm_suspend_all() to suspend the running PCM streams. + Save the register values if necessary. + Stop the hardware if necessary. + Set the power-state as D3hot by calling snd_power_change_state(). + + + + + A typical code would be like: + + + +card; + // (1) + if (card->power_state == SNDRV_CTL_POWER_D3hot) + return; + // (2) + snd_pcm_suspend_all(chip->pcm); + // (3) + snd_mychip_save_registers(chip); + // (4) + snd_mychip_stop_hardware(chip); + // (5) + snd_power_change_state(card, SNDRV_CTL_POWER_D3hot); + } +]]> + + + + + + The scheme of the real resume job is as following. + + + Check whether the power-state is already D0. + If yes, skip the job. + Enable the pci device again by calling + pci_enable_device(). + Re-initialize the chip. + Restore the saved registers if necessary. + Resume the mixer, e.g. calling + snd_ac97_resume(). + Restart the hardware (if any). + Set the power-state as D0 by calling + snd_power_change_state(). + + + + + A typical code would be like: + + + +card; + // (1) + if (card->power_state == SNDRV_CTL_POWER_D0) + return; + // (2) + pci_enable_device(chip->pci); + // (3) + snd_mychip_reinit_chip(chip); + // (4) + snd_mychip_restore_registers(chip); + // (5) + snd_ac97_resume(chip->ac97); + // (6) + snd_mychip_restart_chip(chip); + // (7) + snd_power_change_state(card, SNDRV_CTL_POWER_D0); + } +]]> + + + + + + In addition to the callbacks above, you should define a callback + for the changes via the ALSA control interface. It's defined + like below: + + + +power_state_private_data, return -ENXIO); + switch (power_state) { + case SNDRV_CTL_POWER_D0: + case SNDRV_CTL_POWER_D1: + case SNDRV_CTL_POWER_D2: + mychip_resume(chip); + break; + case SNDRV_CTL_POWER_D3hot: + case SNDRV_CTL_POWER_D3cold: + mychip_suspend(chip); + break; + default: + return -EINVAL; + } + return 0; + } +]]> + + + + + + OK, we have all callbacks now. Let's set up them now. In the + initialization of the card, add the following: + + + +set_power_state = snd_mychip_set_power_state; + card->power_state_private_data = chip; + #endif + .... + } +]]> + + + + + + If you need a space for saving the registers, you'll need to + allocate the buffer for it here, too, since you cannot call + kmalloc() with + GFP_KERNEL flag or + vmalloc() in the suspend callback. + The allocated buffer should be released in the corresponding + destructor. + + + + And next, set suspend/resume callbacks to the pci_driver, + + + + + + + + + + Last but not least: Please keep in mind that you cannot call + schedule() during the suspend and the resume + callbacks. If any delay is necessary, you have to use + mdelay() or udelay() + instead of schedule_timeout()! + Of course, semaphores cannot be used, too, which will invoke sleep + inside. + + + + + + + + + Module Parameters + + There are standard module options for ALSA. At least, each + module should have index, + id and enable + options. + + + + If the module supports multiple cards (usually up to + 8 = SNDRV_CARDS cards), they should be + arrays. The default initial values are defined already as + constants for ease of programming: + + + + + + + + + + If the module supports only a single card, they could be single + variables, instead. enable option is not + always necessary in this case, but it wouldn't be so bad to have a + dummy option for compatibility. + + + + The module parameters must be declared with the standard + MODULE_PARM() and + MODULE_PARM_DESC() macros. The ALSA provides + an additional macro, MODULE_PARM_SYNTAX(), + for describing its syntax. The strings will be written to + /lib/modules/XXX/modules.generic_string + file. + + + + For convenience, the typical string arguments given to + MODULE_PARM_SYNTAX() are defined in + <sound/initval.h>, such as + SNDRV_ID_DESC or + SNDRV_ENABLED. + + + + The typical coding would be like below: + + + + + + + + + + Also, don't forget to define the module description, classes, + license and devices. Especially, the recent modprobe requires to + define the module license as GPL, etc., otherwise the system is + shown as tainted. + + + + + + + + + + For building the driver into kernel, you should define the + setup() function in addition, too. + ALSA provides get_id() function to retrieve + a string argument from the kernel boot parameters. + + + += SNDRV_CARDS) + return 0; + (void)(get_option(&str,&enable[nr_dev]) == 2 && + get_option(&str,&index[nr_dev]) == 2 && + get_id(&str,&id[nr_dev]) == 2); + nr_dev++; + return 1; + } + + __setup("snd-mychip=", alsa_card_mychip_setup); + + #endif /* ifndef MODULE */ +]]> + + + + + + + + + + + Useful Functions + +
+ <function>snd_printk()</function> and friends + + ALSA provides a verbose version of + printk() function. If a kernel config + CONFIG_SND_VERBOSE_PRINTK is set, this + function prints the given message together with the file name + and the line of the caller. The KERN_XXX + prefix is processed as + well as the original printk() does, so it's + recommended to add this prefix, e.g. + + + + + + + + + + There are also printk()'s for + debugging. snd_printd() can be used for + general debugging purposes. If + CONFIG_SND_DEBUG is set, this function is + compiled, and works just like + snd_printk(). If the ALSA is compiled + without the debugging flag, it's ignored. + + + + snd_printdd() is compiled in only when + CONFIG_SND_DEBUG_DETECT is set. Please note + that DEBUG_DETECT is not set as default + even if you configure the alsa-driver with + option. You need to give + explicitly option instead. + +
+ +
+ <function>snd_assert()</function> + + snd_assert() macro is similar with the + normal assert() macro. For example, + + + + + + + + + + The first argument is the expression to evaluate, and the + second argument is the action if it fails. When + CONFIG_SND_DEBUG, is set, it will show an + error message such as BUG? (xxx) (called from + yyy). When no debug flag is set, this is + ignored. + +
+ +
+ <function>snd_runtime_check()</function> + + This macro is quite similar with + snd_assert(). Unlike + snd_assert(), the expression is always + evaluated regardless of + CONFIG_SND_DEBUG. When + CONFIG_SND_DEBUG is set, the macro will + show a message like ERROR (xx) (called from + yyy). + +
+ +
+ <function>snd_BUG()</function> + + It calls snd_assert(0,) -- that is, just + prints the error message at the point. It's useful to show that + a fatal error happens there. + +

This shows in the same syntax of +/dev/sndstat, which is available on the commercial OSS driver. +On ALSA, you can symlink /dev/sndstat to this proc file. + +Please note that the devices listed in this proc file appear only +after the corresponding OSS-emulation module is loaded. Don't worry +even if "NOT ENABLED IN CONFIG" is shown in it. + + +Device Mapping +============== + +ALSA supports the following OSS device files: + + PCM: + /dev/dspX + /dev/adspX + + Mixer: + /dev/mixerX + + MIDI: + /dev/midi0X + /dev/amidi0X + + Sequencer: + /dev/sequencer + /dev/sequencer2 (aka /dev/music) + +where X is the card number from 0 to 7. + +(NOTE: Some distributions have the device files like /dev/midi0 and + /dev/midi1. They are NOT for OSS but for tclmidi, which is + a totally different thing.) + +Unlike the real OSS, ALSA cannot use the device files more than the +assigned ones. For example, the first card cannot use /dev/dsp1 or +/dev/dsp2, but only /dev/dsp0 and /dev/adsp0. + +As seen above, PCM and MIDI may have two devices. Usually, the first +PCM device (hw:0,0 in ALSA) is mapped to /dev/dsp and the secondary +device (hw:0,1) to /dev/adsp (if available). For MIDI, /dev/midi and +/dev/amidi, respectively. + +You can change this device mapping via the module options of +snd-pcm-oss and snd-rawmidi. In the case of PCM, the following +options are available for snd-pcm-oss: + + dsp_map PCM device number assigned to /dev/dspX + (default = 0) + adsp_map PCM device number assigned to /dev/adspX + (default = 1) + +For example, to map the third PCM device (hw:0,2) to /dev/adsp0, +define like this: + + options snd-pcm-oss adsp_map=2 + +The options take arrays. For configuring the second card, specify +two entries separated by comma. For example, to map the third PCM +device on the second card to /dev/adsp1, define like below: + + options snd-pcm-oss adsp_map=0,2 + +To change the mapping of MIDI devices, the following options are +available for snd-rawmidi: + + midi_map MIDI device number assigned to /dev/midi0X + (default = 0) + amidi_map MIDI device number assigned to /dev/amidi0X + (default = 1) + +For example, to assign the third MIDI device on the first card to +/dev/midi00, define as follows: + + options snd-rawmidi midi_map=2 + + +PCM Mode +======== + +As default, ALSA emulates the OSS PCM with so-called plugin layer, +i.e. tries to convert the sample format, rate or channels +automatically when the card doesn't support it natively. +This will lead to some problems for some applications like quake or +wine, especially if they use the card only in the MMAP mode. + +In such a case, you can change the behavior of PCM per application by +writing a command to the proc file. There is a proc file for each PCM +stream, /proc/asound/cardX/pcmY[cp]/oss, where X is the card number +(zero-based), Y the PCM device number (zero-based), and 'p' is for +playback and 'c' for capture, respectively. Note that this proc file +exists only after snd-pcm-oss module is loaded. + +The command sequence has the following syntax: + + app_name fragments fragment_size [options] + +app_name is the name of application with (higher priority) or without +path. +fragments specifies the number of fragments or zero if no specific +number is given. +fragment_size is the size of fragment in bytes or zero if not given. +options is the optional parameters. The following options are +available: + + disable the application tries to open a pcm device for + this channel but does not want to use it. + direct don't use plugins + block force block open mode + non-block force non-block open mode + +The disable option is useful when one stream direction (playback or +capture) is not handled correctly by the application although the +hardware itself does support both directions. +The direct option is used, as mentioned above, to bypass the automatic +conversion and useful for MMAP-applications. +For example, to playback the first PCM device without plugins for +quake, send a command via echo like the following: + + % echo "quake 0 0 direct" > /proc/asound/card0/pcm0p/oss + +While quake wants only playback, you may append the second command +to notify driver that only this direction is about to be allocated: + + % echo "quake 0 0 disable" > /proc/asound/card0/pcm0c/oss + +The permission of proc files depend on the module options of snd. +As default it's set as root, so you'll likely need to be superuser for +sending the command above. + +The block and non-block options are used to change the behavior of +opening the device file. +As default, ALSA behaves as defined in POSIX, i.e. blocks the file +when it's busy until the device becomes free (unless O_NONBLOCK is +specified). Some applications assume the non-block open behavior, +which are actually implemented in some real OSS drivers. + +This blocking behavior can be changed globally via nonblock_open +module option of snd-pcm-oss. For using the non-block mode as default +for OSS devices, define like the following: + + options snd-pcm-oss nonblock_open=1 + +You can check the currently defined configuration by reading the proc +file. The read image can be sent to the proc file again, hence you +can save the current configuration + + % cat /proc/asound/card0/pcm0p/oss > /somewhere/oss-cfg + +and restore it like + + % cat /somewhere/oss-cfg > /proc/asound/card0/pcm0p/oss + +Also, for clearing all the current configuration, send "erase" command +as below: + + % echo "erase" > /proc/asound/card0/pcm0p/oss + + +Mixer Elements +============== + +Since ALSA has completely different mixer interface, the emulation of +OSS mixer is relatively complicated. ALSA builds up a mixer element +from several different ALSA (mixer) controls based on the name +string. For example, the volume element SOUND_MIXER_PCM is composed +from "PCM Playback Volume" and "PCM Playback Switch" controls for the +playback direction and from "PCM Capture Volume" and "PCM Capture +Switch" for the capture directory (if exists). When the PCM volume of +OSS is changed, all the volume and switch controls above are adjusted +automatically. + +As default, ALSA uses the following control for OSS volumes: + + OSS volume ALSA control Index + ----------------------------------------------------- + SOUND_MIXER_VOLUME Master 0 + SOUND_MIXER_BASS Tone Control - Bass 0 + SOUND_MIXER_TREBLE Tone Control - Treble 0 + SOUND_MIXER_SYNTH Synth 0 + SOUND_MIXER_PCM PCM 0 + SOUND_MIXER_SPEAKER PC Speaker 0 + SOUND_MIXER_LINE Line 0 + SOUND_MIXER_MIC Mic 0 + SOUND_MIXER_CD CD 0 + SOUND_MIXER_IMIX Monitor Mix 0 + SOUND_MIXER_ALTPCM PCM 1 + SOUND_MIXER_RECLEV (not assigned) + SOUND_MIXER_IGAIN Capture 0 + SOUND_MIXER_OGAIN Playback 0 + SOUND_MIXER_LINE1 Aux 0 + SOUND_MIXER_LINE2 Aux 1 + SOUND_MIXER_LINE3 Aux 2 + SOUND_MIXER_DIGITAL1 Digital 0 + SOUND_MIXER_DIGITAL2 Digital 1 + SOUND_MIXER_DIGITAL3 Digital 2 + SOUND_MIXER_PHONEIN Phone 0 + SOUND_MIXER_PHONEOUT Phone 1 + SOUND_MIXER_VIDEO Video 0 + SOUND_MIXER_RADIO Radio 0 + SOUND_MIXER_MONITOR Monitor 0 + +The second column is the base-string of the corresponding ALSA +control. In fact, the controls with "XXX [Playback|Capture] +[Volume|Switch]" will be checked in addition. + +The current assignment of these mixer elements is listed in the proc +file, /proc/asound/cardX/mixer_oss, which will be like the following + + VOLUME "Master" 0 + BASS "" 0 + TREBLE "" 0 + SYNTH "" 0 + PCM "PCM" 0 + ... + +where the first column is the OSS volume element, the second column +the base-string of the corresponding ALSA control, and the third the +control index. When the string is empty, it means that the +corresponding OSS control is not available. + +For changing the assignment, you can write the configuration to this +proc file. For example, to map "Wave Playback" to the PCM volume, +send the command like the following: + + % echo 'VOLUME "Wave Playback" 0' > /proc/asound/card0/mixer_oss + +The command is exactly as same as listed in the proc file. You can +change one or more elements, one volume per line. In the last +example, both "Wave Playback Volume" and "Wave Playback Switch" will +be affected when PCM volume is changed. + +Like the case of PCM proc file, the permission of proc files depend on +the module options of snd. you'll likely need to be superuser for +sending the command above. + +As well as in the case of PCM proc file, you can save and restore the +current mixer configuration by reading and writing the whole file +image. + + +Unsupported Features +==================== + +MMAP on ICE1712 driver +---------------------- +ICE1712 supports only the unconventional format, interleaved +10-channels 24bit (packed in 32bit) format.

We should enable the parity interrupt in the SIEN0 register. - * - * 3. intr_phase_mismatch() needs to believe that message out is - * always an "acceptable" phase to have a mismatch in. If - * the old phase was MSG_IN, we should send a MESSAGE PARITY - * error. If the old phase was something else, we should send - * a INITIATOR_DETECTED_ERROR message.
