[AGPGART] Replace check_bridge_mode() with (bridge->mode & AGSTAT_MODE_3_0).
As mentioned earlier, the current check_bridge_mode() code assumes
that AGP bridges are PCI devices. This isn't always true. Definitely
not for HP zx1 chipset and the same seems to be the case for SGI's AGP
bridge.
The patch below fixes the problem by picking up the AGP_MODE_3_0 bit
from bridge->mode. I feel like I may be missing something, since I
can't see any reason why check_bridge_mode() wasn't doing that in the
first place. According to the AGP 3.0 specs, the AGP_MODE_3_0 bit is
determined during the hardware reset and cannot be changed, so it
seems to me it should be safe to pick it up from bridge->mode.
With the patch applied, I can definitely use AGP acceleration both
with AGP 2.0 and AGP 3.0 (one with an Nvidia card, the other with an
ATI FireGL card).
Unless someone spots a problem, please apply this patch so 3d
acceleration can work on zx1 boxes again.
This makes AGP work again on machines with an AGP bridge that isn't a
PCI device.

When Linux is running on the Xen virtual machine monitor, physical
addresses are virtualised and cannot be directly referenced by the AGP
GART. This patch fixes the GART driver for Xen by adding a layer of
abstraction between physical addresses and 'GART addresses'.
Architecture-specific functions are also defined for allocating and freeing
the GATT. Xen requires this to ensure that table really is contiguous from
the point of view of the GART.
These extra interface functions are defined as 'no-ops' for all existing
architectures that use the GART driver.

On some 5701 devices with older bootcode, the LED configuration bits in
SRAM may be invalid with value zero. The fix is to check for invalid
bits (0) and default to PHY 1 mode. Incorrect LED mode will lead to
error in programming the PHY.
Thanks to Grant Grundler for debugging the problem.
>From Grant:
| In May, 2004, tg3 v3.4 changed how MAC_LED_CTRL (0x40c) was getting
| programmed and how to determine what to program into LED_CTRL. The new
| code trusted NIC_SRAM_DATA_CFG (0x00000b58) to indicate what to write
| to LED_CTRL and MII EXT_CTRL registers. On "IOX Core Lan", SRAM was
| saying MODE_MAC (0x0) and that doesn't work.

With CONFIG_DEBUG_SLAB=y I see slab corruption messages during boot on
pSeries machines with IPR adapters with any 2.6.12-rc kernel.
The change which seems to have introduced the problem is "SCSI: revamp
target scanning routines" and may be found at:
http://marc.theaimsgroup.com/?l=bk-commits-head&m=111093946426333&w=2
In order to revert that in a 2.6.12-rc1 tree, I had to revert "target
code updates to support scanned targets" first:
http://marc.theaimsgroup.com/?l=bk-commits-head&m=111094132524649&w=2
With both patches reverted, the corruption messages go away.

This patch adds a new driver for "Option" cards. This is a GSM data card,
controlled by three "serial ports" which are connected via an OHCI adapter,
all located on an oversized PC-Card. It's sold by several GSM service
providers.
Traditionally, this card has been accessed via the standard serial driver
and appropriate vendor= and product= options. However, testing has
revealed several problems with this approach, including hung data transfers
and lost data blocks when receiving.
Therefore, I've written a separate driver.

A new cpufreq module, based on the ondemand one with my additional patches
just posted. This one is more suitable for battery environments where its
probably more appealing to have the cpu freq gracefully increase and decrease
rather than flip between the min and max freq's.
N.B. Bruno Ducrot pointed out that the amd64's "do have unacceptable latency
between min and max freq transition, due to the step-by-step requirements
(200MHz IIRC)"; so AMD64 users would probably benefit from this too.

Here is my third attempt at a patch to further update the CompactPCI
hotplug driver infrastructure to address the pci_enable_device issue
discussed on the list as well as a few other issues I discovered during
some more testing. This version addresses a few more issues pointed out
by Prarit Bhargava. Changes include:
- cpci_enable_device and its recursive calling of pci_enable_device on
new devices removed.
- Use list_rwsem to avoid slot status change races between disable_slot
and check_slots.
- Fixed oopsing in cpci_hp_unregister_bus caused by calling list_del on
a slot after calling pci_hp_deregister.
- Removed kfree calls in cleanup_slots since release_slot will have
done it already.
- Reworked init_slots a bit to fix latch and adapter file updating on
subsequent calls to cpci_hp_start.
- Improved sanity checking in cpci_hp_register_controller.
- Now shut things down correctly in cpci_hotplug_exit.
- Switch to pci_get_slot instead of deprecated pci_find_slot.
- A bunch of CodingStyle fixes.

Various fixes to the sl811-hcd driver:
* Fix small glitches that crept in during recent evolution of usbcore's hcd
glue layer, coupling endpoint state records to usbcore and active urbs.
(As noted by folk whose boards weren't stuck on 2.6.9 kernels...)
* Cope with various system-specific issues:
- Some configurations (e.g. a CF-card uses this chip) have iospace
addresses for the two registers, rather than memory mapped ones.
- Some configurations do interesting things with IRQs; maybe the
line is shared, or it doesn't support level triggering.
- Not all boards can drive the chip reset line in software.
* Address a potential race during unlinking.
* Tweak probe/remove section info to handle the case where this segment
of a platform bus is hotpluggable (e.g. CF card). (The basic problem

This patch fixes "grave" bugs in i2c-ali1563 driver. It seems on recent
chipset revisions the HSTS_DONE is set only for block transfers, so we
must detect the end of ordinary transaction other way. Also due to missing
and mask, setting other transfer modes was not possible. Moreover the
continous byte mode transfer uses DAT0 for command rather than CMD command.
All those changes were tested with help of Chunhao Huang from Winbond.
I'm willing to maintain the driver. Second patch adds me as maintainer
if this is neccessary.

On Nov 16 2004 a change to intelfbdrv.c was commited (as part of 0.9.2 it
looks like) that added __initdata to all of the module param variables that
seems to create the opportunity for an oops.
I've recently been chasing an OOPS
(http://marc.theaimsgroup.com/?l=linux-kernel&m=111552250920370&w=2) I
created by reading every file on the /sys file system and I've traced it
back to this code in the intelfbdrv. Though I had root privs in my initial
problem report, it turns out they are un-necessary to generate the oops -
all you've got to do is "cat /sys/module/intelfb/parameters/mode" enough
times and eventually it will oops.
This is because sysfs automatically exports all module_param declarations
to the sysfs file system.. which means those variables can be dynamically
evaluated at any later time, which of course means marking them __initdata
is a bad idea ;).. when they happen to be char *'s it is an especially bad
idea ;).
Applying the patch below clears up the OOPS for me.

Recent kernels occasionally trigger a PMU timeout on some mac laptops,
typically on wakeup from sleep. This seem to be caused by either a too big
latency caused by the cpufreq switch on wakeup from sleep or by an
interrupt beeing lost due to the reset of the interrupt controller done
during wakeup.
This patch makes that code more robust by stopping PMU auto poll activity
around cpufreq changes on machines that use the PMU for such changes (long
latency switching involving a CPU hard reset and flush of all caches) and
by removing the reset of the open pic interrupt controller on wakeup (that
can cause the loss of an interrupt and Darwin doesn't do it, so it must not
be necessary).

This patch adds dummy gameport_register_port, gameport_unregister_port
and gameport_set_phys functions to gameport.h for the case when a driver
can't use gameport.
This fixes the compilation of some OSS drivers with GAMEPORT=n without
the need to #if inside every single driver.
This patch also removes the non-working and now obsolete SOUND_GAMEPORT.
This patch is also an alternative solution for ALSA drivers with similar
problems (but #if's inside the drivers might have the advantage of
saving some more bytes of gameport is not available).
The only user-visible change is that for GAMEPORT=m the affected OSS
drivers are now allowed to be built statically (but they won't have
gameport support).

The original pwc author raised some questions about the reverse
engineering of the decompressor algorithms used in the pwc driver.
Having done some detailed investigation it appears those concerns that
clean room policy was not followed are reasonable. I've also had a
friendly discussion with Philips to ask their view on this.
This removes the problem items of code which reduces the pwc
functionality in the kernel a little but leaves all the framework for
setup that will be needed for decompressors in user space (where they
eventually belong). This change set is designed to be the minimal risk
change set given that 2.6.12 is hopefully close to hand, with a view to
merging the much updated pwc code in 2.6.13 series kernels.
Someone else can then redo the decompressors properly (clean room) in
user space.
Note that while its easy to say that it should have been caught earlier,
but the violation was really only obvious to someone who had access to
both the proprietary source and the 'GPL' source.

Jens Axboe pointed out that the iounmap() call in libata was occurring
too early, and some drivers (ahci, probably others) were using ioremap'd
memory after it had been unmapped.
The patch should address that problem by way of improving the libata
driver API:
* move ->host_stop() call after all ->port_stop() calls have occurred.
* create default helper function ata_host_stop(), and move iounmap()
call there.
* add ->host_stop_prewalk() hook, use it in sata_qstor.c (hi Mark).
sata_qstor appears to require the host-stop-before-port-stop ordering
that existed prior to applying the attached patch.

inserted a CD in it
From: Marcello Maggioni <hayarms@gmail.com>
Problem: Some drives (NEC 3500, TDK 1616N, Mad-dog MD-16XDVD9, RICOH
MP5163DA, Memorex DVD9 drive and IO-DATA's too for sure), if a
CD/DVD is inserted into the tray when the system is booted and if
before the OS bootup the BIOS checked for the presence of a bootable
CD/DVD into the drive, during the IDE probe phase the drive may
result busy and remain so for the next 25/30 seconds . This cause the
drive to be skipped during the booting phase and not begin usable
until the next reboot (if the reboot goes well and the drive doesn't
timeout again).
Solution: Rising the timeout time from 10 seconds to 35 seconds
(during these 35 seconds every drive should wake up for sure
according to the tests I've done).

When testing ATAPI PIO data transfer on the ppc64 platform, __atapi_pio_bytes() got zero when
sg_dma_len() is used. I checked the <asm-ppc64/scatterlish.h>, the struct scatterlist is defined as:
struct scatterlist {
struct page *page;
unsigned int offset;
unsigned int length;
/* For TCE support */
u32 dma_address;
u32 dma_length;
};
#define sg_dma_address(sg) ((sg)->dma_address)
#define sg_dma_len(sg) ((sg)->dma_length)
So, if the scatterlist is not DMA mapped, sg_dma_len() will return zero on ppc64.
The same problem should occur on the x86-64 platform.
On the i386 platform, sg_dma_len() returns sg->length, that's why the problem does not occur on an i386.
Changes:
- Use sg->length if the scatterlist is not DMA mapped (yet).

Check if a client passes a NULL callback into an SA query, and if so, never
call back. This fixes an oops if someone unloads ib_ipoib and ib_sa in
rapid succession. ib_ipoib does an MCMember delete with a NULL callback
and 0 timeout on unload, which is usually fine since the delete completes
successfully. However, if ib_sa is unloaded immediately afterwards, the
delete will be canceled and ib_sa will try to call the (now already
unloaded) ib_ipoib module back with the cancel completion, which triggers
the oops.

sub-optimal "polled" mode (heh, maybe they didn't even notice the bug
because of that :), our driver didn't properly check and crashes :(
This patch fixes our driver to not crash, and adds code to the
prom_init() OF trampoline code that detects the "bug" and adds the
missing information back for this chipset revision. This fixes booting
and thermal control on these models.

If you tried to open a packet device first in read-only mode and then a
second time in read-write mode, the second open succeeded even though the
device was not correctly set up for writing. If you then tried to write
data to the device, the writes would fail with I/O errors.
This patch prevents that problem by making the second open fail with
-EBUSY.

The new period/dt setting routines don't get the coupling of these

device timer
The allocation of all of our components should be done in slave alloc.
Currently it's rather fancifully refcounted in the queuecommand
callback. This patch moves allocation and destroy to their correct
places in slave_alloc/slave_destory. Now we can guarantee that
everywhere a device is requested, it's actually been allocated, so don't
check for this anymore.
Additionally, the per device busy timer was the only source of potential
use after free. It's been deleted because Linux does the correct thing
with busy returns, so there's no need to implement a separate timer in
the driver.
Finally, implement code that forces all the device parameters to zero
(i.e. async and narrow) in the slave alloc, inform the spi class of the
bios recorded maximums and wait until slave configure before trying
anything more adventurous.

The aic7xxx driver has two spurious queues in it's linux glue code: the
busyq which queues incoming commands to the driver and the completeq
which queues finished commands before sending them back to the mid-layer
This patch just removes the busyq and makes the aic finally return the
correct status to get the mid-layer to manage its queueing, so a command
is either committed to the sequencer or returned to the midlayer for
requeue.

There's a basic need not to have parameters go under or over certain
values when doing domain validation. The basic ones are
max_offset, max_width and min_period
This patch makes the transport class take and enforce these three
limits. Currently they can be set by the user, although they could
obviously be read from the HBA's on-board NVRAM area during
slave_configure (if it has one).

Even though we do software interrupt mitigation
via NAPI, it still helps to have some minimal
hw assisted mitigation.
This helps, particularly, on systems where register
I/O overhead is much greater than the CPU horsepower.
For example, it helps on NUMA systems. In such cases
the PIO overhead to disable interrupts for NAPI accounts
for the majority of the packet processing cost. The
CPU is fast enough such that only a single packet is
processed by each NAPI poll call.
Thanks to Michael Chan for reviewing this patch.

When supported, use the TAGGED interrupt processing support
the chip provides. In this mode, instead of a "on/off" binary
semaphore, an incrementing tag scheme is used to ACK interrupts.
All MSI supporting chips support TAGGED mode, so the tg3_msi()
interrupt handler uses it unconditionally. This invariant is
verified when MSI support is tested.
Since we can invoke tg3_poll() multiple times per interrupt under
high packet load, we fetch a new copy of the tag value in the
status block right before we actually do the work.
Also, because the tagged status tells the chip exactly which
work we have processed, we can make two optimizations:
1) tg3_restart_ints() need not check tg3_has_work()
2) the tg3_timer() need not poke the chip 10 times per
second to keep from losing interrupt events

Don't pass meaningless file handles to block device ioctls.
The recent raw IO ioctl-passthrough fix started passing the raw file
handle into the block device ioctl handler. That's unlikely to be
useful, as the file handle is actually open on a character-mode raw
device, not a block device, so dereferencing it is not going to yield
useful results to a block device ioctl handler.
Previously we just passed NULL; also not a value that can usefully
be dereferenced, but at least if it does happen, we'll oops instead of
silently pretending that the file is a block device, so NULL is the more
defensive option here. This patch reverts to that behaviour.
Noticed by Al Viro.

The driver model has a "detach_state" mechanism that:
- Has never been used by any in-kernel drive;
- Is superfluous, since driver remove() methods can do the same thing;
- Became buggy when the suspend() parameter changed semantics and type;
- Could self-deadlock when called from certain suspend contexts;
- Is effectively wasted documentation, object code, and headspace.
This removes that "detach_state" mechanism; net code shrink, as well
as a per-device saving in the driver model and sysfs.

This patch includes various tweaks in the messaging that appears during
system pm state transitions:
* Warn about certain illegal calls in the device tree, like resuming
child before parent or suspending parent before child. This could
happen easily enough through sysfs, or in some cases when drivers
use device_pm_set_parent().
* Be more consistent about dev_dbg() tracing ... do it for resume() and
shutdown() too, and never if the driver doesn't have that method.
* Say which type of system sleep state is being entered.
Except for the warnings, these only affect debug messaging.

[PATCH] CPCI: update
I have finally done some work to update the CompactPCI hotplug driver to
fix some of the outstanding issues in 2.6:
- Added adapter and latch status ops so that those files will get created
by the current PCI hotplug core. This used to not be required, but
seems to be now after some of the sysfs rework in the core.
- Replaced slot list spinlock with a r/w semaphore to avoid any potential
issues with sleeping. This quiets all of the runtime warnings.
- Reworked interrupt driven hot extraction handling to remove need for a
polling operator for ENUM# status. There are a lot of boards that only
have an interrupt driven by ENUM#, so this lowers the bar to entry.
- Replaced pci_visit_dev usage with better use of the PCI core functions.
The new code is functionally equivalent to the previous code, but the
use of pci_enable_device on insert needs to be investigated further, as
I need to do some more testing to see if it is still necessary.
