5 daysPCI/ASPM: Clarify that pcie_aspm=off means leave ASPM untouchedBjorn Helgaas1-2/+3
Previously we claimed "pcie_aspm=off" meant that ASPM would be disabled, which is wrong. Correct this to say that with "pcie_aspm=off", Linux doesn't touch any ASPM configuration at all. ASPM may have been enabled by firmware, and that will be left unchanged. See "aspm_support_enabled".

This effectively limited the max concurrency of unbound pools on single node systems to 8 causing performance regressions on some workloads. Fixed by setting the default pool's node_nr_active to max_active. - wq_update_node_max_active() could trigger divide-by-zero if the intersection between the allowed CPUs for an unbound workqueue and online CPUs becomes empty. - When kick_pool() was trying to repatriate a worker to a CPU in its pod by setting task->wake_cpu, it didn't consider whether the CPU being selected is online or not which obviously can lead to subobtimal behaviors. On s390, this triggered a crash in arch code. The workqueue patch removes the gross misbehavior but doesn't fix the crash completely as there's a race window in which CPUs can go down after wake_cpu is set.

11 dayssched/isolation: Prevent boot crash when the boot CPU is nohz_fullOleg Nesterov1-5/+2
Documentation/timers/no_hz.rst states that the "nohz_full=" mask must not include the boot CPU, which is no longer true after: 08ae95f4fd3b ("nohz_full: Allow the boot CPU to be nohz_full"). However after: aae17ebb53cd ("workqueue: Avoid using isolated cpus' timers on queue_delayed_work") the kernel will crash at boot time in this case; housekeeping_any_cpu() returns an invalid CPU number until smp_init() brings the first housekeeping CPU up. Change housekeeping_any_cpu() to check the result of cpumask_any_and() and return smp_processor_id() in this case. This is just the simple and backportable workaround which fixes the symptom, but smp_processor_id() at boot time should be safe at least for type == HK_TYPE_TIMER, this more or less matches the tick_do_timer_boot_cpu logic. There is no worry about cpu_down(); tick_nohz_cpu_down() will not allow to offline tick_do_timer_cpu (the 1st online housekeeping CPU).

13 dayscpu: Ignore "mitigations" kernel parameter if CPU_MITIGATIONS=nSean Christopherson1-0/+3
Explicitly disallow enabling mitigations at runtime for kernels that were built with CONFIG_CPU_MITIGATIONS=n, as some architectures may omit code entirely if mitigations are disabled at compile time. E.g. on x86, a large pile of Kconfigs are buried behind CPU_MITIGATIONS, and trying to provide sane behavior for retroactively enabling mitigations is extremely difficult, bordering on impossible. E.g. page table isolation and call depth tracking require build-time support, BHI mitigations will still be off without additional kernel parameters, etc. [ bp: Touchups. ] Signed-off-by: Sean Christopherson <seanjc@google.com> Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> Acked-by: Borislav Petkov (AMD) <bp@alien8.de> Link: https://lore.kernel.org/r/20240420000556.2645001-3-seanjc@google.com

2024-04-16mm,page_owner: fix refcount imbalanceOscar Salvador1-35/+38
Current code does not contemplate scenarios were an allocation and free operation on the same pages do not handle it in the same amount at once. To give an example, page_alloc_exact(), where we will allocate a page of enough order to stafisfy the size request, but we will free the remainings right away. In the above example, we will increment the stack_record refcount only once, but we will decrease it the same number of times as number of unused pages we have to free. This will lead to a warning because of refcount imbalance. Fix this by recording the number of base pages in the refcount field.

2024-04-15docs: verify/bisect: stable regressions: first stable, then mainlineThorsten Leemhuis1-40/+51
Rearrange the instructions so that readers facing a regression within a stable or longterm series first test its latest release before testing mainline. This is less scary for some people. It also reduces the chance that something goes sideways for readers that compile their first kernel, as mainline can cause slightly more trouble.

This checks if a transaction has touched too many btree paths (because of iteration over many keys), and isuses a restart to drop unneeded paths. But it's now possible for some paths to exceed the previous limit without iteration in the interior btree update path, since the transaction commit will do alloc updates for every old and new btree node, and during journal replay we don't use the btree write buffer for locking reasons and thus those updates use btree paths when they wouldn't normally. - Fix a corner case in rebalance when moving extents on a durability=0 device. This wouldn't be hit when a device was formatted with durability=0 since in that case we'll only use it as a write through cache (only cached extents will live on it), but durability can now be changed on an existing device. - bch2_get_acl() could rarely forget to handle a transaction restart; this manifested as the occasional missing acl that came back after dropping caches. - Fix a major performance regression on high iops multithreaded write workloads (only since 6.9-rc1); a previous fix for a deadlock in the interior btree update path to check the journal watermark introduced a dependency on the state of btree write buffer flushing that we didn't want. - Assorted other repair paths and recovery fixes" * tag 'bcachefs-2024-04-10' of https://evilpiepirate.org/git/bcachefs: (25 commits) bcachefs: Fix __bch2_btree_and_journal_iter_init_node_iter() bcachefs: Kill read lock dropping in bch2_btree_node_lock_write_nofail() bcachefs: Fix a race in btree_update_nodes_written() bcachefs: btree_node_scan: Respect member.data_allowed bcachefs: Don't scan for btree nodes when we can reconstruct bcachefs: Fix check_topology() when using node scan bcachefs: fix eytzinger0_find_gt() bcachefs: fix bch2_get_acl() transaction restart handling bcachefs: fix the count of nr_freed_pcpu after changing bc->freed_nonpcpu list bcachefs: Fix gap buffer bug in bch2_journal_key_insert_take() bcachefs: Rename struct field swap to prevent macro naming collision MAINTAINERS: Add entry for bcachefs documentation Documentation: filesystems: Add bcachefs toctree bcachefs: JOURNAL_SPACE_LOW bcachefs: Disable errors=panic for BCH_IOCTL_FSCK_OFFLINE bcachefs: Fix BCH_IOCTL_FSCK_OFFLINE for encrypted filesystems bcachefs: fix rand_delete unit test bcachefs: fix ! vs ~ typo in __clear_bit_le64() bcachefs: Fix rebalance from durability=0 device bcachefs: Print shutdown journal sequence number ...

2024-03-29dt-bindings: bluetooth: add 'qcom,local-bd-address-broken'Johan Hovold1-0/+4
Several Qualcomm Bluetooth controllers lack persistent storage for the device address and instead one can be provided by the boot firmware using the 'local-bd-address' devicetree property. The Bluetooth bindings clearly states that the address should be specified in little-endian order, but due to a long-standing bug in the Qualcomm driver which reversed the address some boot firmware has been providing the address in big-endian order instead. The only device out there that should be affected by this is the WCN3991 used in some Chromebooks. Add a 'qcom,local-bd-address-broken' property which can be set on these platforms to indicate that the boot firmware is using the wrong byte order. Note that ChromeOS always updates the kernel and devicetree in lockstep so that there is no need to handle backwards compatibility with older devicetrees.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Thomas Gleixner: - Ensure that the encryption mask at boot is properly propagated on 5-level page tables, otherwise the PGD entry is incorrectly set to non-encrypted, which causes system crashes during boot. - Undo the deferred 5-level page table setup as it cannot work with memory encryption enabled. - Prevent inconsistent XFD state on CPU hotplug, where the MSR is reset to the default value but the cached variable is not, so subsequent comparisons might yield the wrong result and as a consequence the result prevents updating the MSR. - Register the local APIC address only once in the MPPARSE enumeration to prevent triggering the related WARN_ONs() in the APIC and topology code. - Handle the case where no APIC is found gracefully by registering a fake APIC in the topology code. That makes all related topology functions work correctly and does not affect the actual APIC driver code at all. - Don't evaluate logical IDs during early boot as the local APIC IDs are not yet enumerated and the invoked function returns an error code. Nothing requires the logical IDs before the final CPUID enumeration takes place, which happens after the enumeration. - Cure the fallout of the per CPU rework on UP which misplaced the copying of boot_cpu_data to per CPU data so that the final update to boot_cpu_data got lost which caused inconsistent state and boot crashes. - Use copy_from_kernel_nofault() in the kprobes setup as there is no guarantee that the address can be safely accessed. - Reorder struct members in struct saved_context to work around another kmemleak false positive - Remove the buggy code which tries to update the E820 kexec table for setup_data as that is never passed to the kexec kernel. - Update the resource control documentation to use the proper units. - Fix a Kconfig warning observed with tinyconfig * tag 'x86-urgent-2024-03-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/boot/64: Move 5-level paging global variable assignments back x86/boot/64: Apply encryption mask to 5-level pagetable update x86/cpu: Add model number for another Intel Arrow Lake mobile processor x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD Documentation/x86: Document that resctrl bandwidth control units are MiB x86/mpparse: Register APIC address only once x86/topology: Handle the !APIC case gracefully x86/topology: Don't evaluate logical IDs during early boot x86/cpu: Ensure that CPU info updates are propagated on UP kprobes/x86: Use copy_from_kernel_nofault() to read from unsafe address x86/pm: Work around false positive kmemleak report in msr_build_context() x86/kexec: Do not update E820 kexec table for setup_data x86/config: Fix warning for 'make ARCH=x86_64 tinyconfig'

2024-03-24Documentation/x86: Document that resctrl bandwidth control units are MiBTony Luck1-4/+4
The memory bandwidth software controller uses 2^20 units rather than 10^6. See mbm_bw_count() which computes bandwidth using the "SZ_1M" Linux define for 0x00100000. Update the documentation to use MiB when describing this feature. It's too late to fix the mount option "mba_MBps" as that is now an established user interface.

2024-03-20tools/rtla: Add -U/--user-load option to timerlatDaniel Bristot de Oliveira1-0/+6
The timerlat tracer provides an interface for any application to wait for the timerlat's periodic wakeup. Currently, rtla timerlat uses it to dispatch its user-space workload (-u option). But as the tracer interface is generic, rtla timerlat can also be used to monitor any workload that uses it. For example, a user might place their own workload to wait on the tracer interface, and monitor the results with rtla timerlat. Add the -U option to rtla timerlat top and hist. With this option, rtla timerlat will not dispatch its workload but only setting up the system, waiting for a user to dispatch its workload. The sample code in this patch is an example of python application that loops in the timerlat tracer fd. To use it, dispatch: # rtla timerlat -U In a terminal, then run the python program on another terminal, specifying the CPU to run it. For example, setting on CPU 1: #./timerlat_load.py 1 Then rtla timerlat will start printing the statistics of the ./timerlat_load.py app. An interesting point is that the "Ret user Timer Latency" value is the overall response time of the load. The sample load does a memory copy to exemplify that. The stop tracing options on rtla timerlat works in this setup as well, including auto analysis.

HEAD Guest-side KVM async #PF ABI cleanup for 6.9 Delete kvm_vcpu_pv_apf_data.enabled to fix a goof in KVM's async #PF ABI where the enabled field pushes the size of "struct kvm_vcpu_pv_apf_data" from 64 to 68 bytes, i.e. beyond a single cache line. The enabled field is purely a guest-side flag that Linux-as-a-guest uses to track whether or not the guest has enabled async #PF support. The actual flag that is passed to the host, i.e. to KVM proper, is a single bit in a synthetic MSR, MSR_KVM_ASYNC_PF_EN, i.e. is in a location completely unrelated to the shared kvm_vcpu_pv_apf_data structure. Simply drop the the field and use a dedicated guest-side per-CPU variable to fix the ABI, as opposed to fixing the documentation to match reality. KVM has never consumed kvm_vcpu_pv_apf_data.enabled, so the odds of the ABI change breaking anything are extremely low.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: "Main user visible change: - User events can now have "multi formats" The current user events have a single format. If another event is created with a different format, it will fail to be created. That is, once an event name is used, it cannot be used again with a different format. This can cause issues if a library is using an event and updates its format. An application using the older format will prevent an application using the new library from registering its event. A task could also DOS another application if it knows the event names, and it creates events with different formats. The multi-format event is in a different name space from the single format. Both the event name and its format are the unique identifier. This will allow two different applications to use the same user event name but with different payloads. - Added support to have ftrace_dump_on_oops dump out instances and not just the main top level tracing buffer. Other changes: - Add eventfs_root_inode Only the root inode has a dentry that is static (never goes away) and stores it upon creation. There's no reason that the thousands of other eventfs inodes should have a pointer that never gets set in its descriptor. Create a eventfs_root_inode desciptor that has a eventfs_inode descriptor and a dentry pointer, and only the root inode will use this. - Added WARN_ON()s in eventfs There's some conditionals remaining in eventfs that should never be hit, but instead of removing them, add WARN_ON() around them to make sure that they are never hit. - Have saved_cmdlines allocation also include the map_cmdline_to_pid array The saved_cmdlines structure allocates a large amount of data to hold its mappings. Within it, it has three arrays. Two are already apart of it: map_pid_to_cmdline[] and saved_cmdlines[]. More memory can be saved by also including the map_cmdline_to_pid[] array as well. - Restructure __string() and __assign_str() macros used in TRACE_EVENT() Dynamic strings in TRACE_EVENT() are declared with: __string(name, source) And assigned with: __assign_str(name, source) In the tracepoint callback of the event, the __string() is used to get the size needed to allocate on the ring buffer and __assign_str() is used to copy the string into the ring buffer. There's a helper structure that is created in the TRACE_EVENT() macro logic that will hold the string length and its position in the ring buffer which is created by __string(). There are several trace events that have a function to create the string to save. This function is executed twice. Once for __string() and again for __assign_str(). There's no reason for this. The helper structure could also save the string it used in __string() and simply copy that into __assign_str() (it also already has its length). By using the structure to store the source string for the assignment, it means that the second argument to __assign_str() is no longer needed. It will be removed in the next merge window, but for now add a warning if the source string given to __string() is different than the source string given to __assign_str(), as the source to __assign_str() isn't even used and will be going away. - Added checks to make sure that the source of __string() is also the source of __assign_str() so that it can be safely removed in the next merge window.

These changes among others ensure modules will be installed when /sbin/installkernel is missing. Furthermore describe better what tasks the script ideally performs so that users can more easily check if those have been taken care of. In addition to that point to the distro's documentation for further details on installing kernels manually.

Pull CXL updates from Dan Williams: "CXL has mechanisms to enumerate the performance characteristics of memory devices. Those mechanisms allow Linux to build the equivalent of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That capability is necessary because static ACPI can not represent dynamic CXL configurations (and reconfigurations). So, building on the v6.8 work to add "Quality of Service" enumeration, this update plumbs CXL "access coordinates" (read/write access latency and bandwidth) in all the same places that ACPI HMAT feeds similar data. Follow-on patches from the -mm side can then use that data to feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to drivers/base/. The other feature update this cycle is support for CXL error injection via the ACPI EINJ module. That facility enables injection of bus protocol errors provided the user knows the magic address values to insert in the interface. To hide that magic, and make this easier to use, new error injection attributes were added to CXL debugfs. That interface injects the errors relative to a CXL object rather than require user tooling to know how to lookup and inject RCRB (Root Complex Register Block) addresses into the raw EINJ debugfs interface. It received some helpful review comments from Tony, but no explicit acks from the ACPI side. The primary user visible change for existing EINJ users is that they may find that einj.ko was already loaded by cxl_core.ko. Previously, einj.ko was only loaded on demand. The usual collection of miscellaneous cleanups are also present this cycle.

Pull kvm updates from Paolo Bonzini: "S390: - Changes to FPU handling came in via the main s390 pull request - Only deliver to the guest the SCLP events that userspace has requested - More virtual vs physical address fixes (only a cleanup since virtual and physical address spaces are currently the same) - Fix selftests undefined behavior x86: - Fix a restriction that the guest can't program a PMU event whose encoding matches an architectural event that isn't included in the guest CPUID. The enumeration of an architectural event only says that if a CPU supports an architectural event, then the event can be programmed *using the architectural encoding*. The enumeration does NOT say anything about the encoding when the CPU doesn't report support the event *in general*. It might support it, and it might support it using the same encoding that made it into the architectural PMU spec - Fix a variety of bugs in KVM's emulation of RDPMC (more details on individual commits) and add a selftest to verify KVM correctly emulates RDMPC, counter availability, and a variety of other PMC-related behaviors that depend on guest CPUID and therefore are easier to validate with selftests than with custom guests (aka kvm-unit-tests) - Zero out PMU state on AMD if the virtual PMU is disabled, it does not cause any bug but it wastes time in various cases where KVM would check if a PMC event needs to be synthesized - Optimize triggering of emulated events, with a nice ~10% performance improvement in VM-Exit microbenchmarks when a vPMU is exposed to the guest - Tighten the check for "PMI in guest" to reduce false positives if an NMI arrives in the host while KVM is handling an IRQ VM-Exit - Fix a bug where KVM would report stale/bogus exit qualification information when exiting to userspace with an internal error exit code - Add a VMX flag in /proc/cpuinfo to report 5-level EPT support - Rework TDP MMU root unload, free, and alloc to run with mmu_lock held for read, e.g. to avoid serializing vCPUs when userspace deletes a memslot - Tear down TDP MMU page tables at 4KiB granularity (used to be 1GiB). KVM doesn't support yielding in the middle of processing a zap, and 1GiB granularity resulted in multi-millisecond lags that are quite impolite for CONFIG_PREEMPT kernels - Allocate write-tracking metadata on-demand to avoid the memory overhead when a kernel is built with i915 virtualization support but the workloads use neither shadow paging nor i915 virtualization - Explicitly initialize a variety of on-stack variables in the emulator that triggered KMSAN false positives - Fix the debugregs ABI for 32-bit KVM - Rework the "force immediate exit" code so that vendor code ultimately decides how and when to force the exit, which allowed some optimization for both Intel and AMD - Fix a long-standing bug where kvm_has_noapic_vcpu could be left elevated if vCPU creation ultimately failed, causing extra unnecessary work - Cleanup the logic for checking if the currently loaded vCPU is in-kernel - Harden against underflowing the active mmu_notifier invalidation count, so that "bad" invalidations (usually due to bugs elsehwere in the kernel) are detected earlier and are less likely to hang the kernel x86 Xen emulation: - Overlay pages can now be cached based on host virtual address, instead of guest physical addresses. This removes the need to reconfigure and invalidate the cache if the guest changes the gpa but the underlying host virtual address remains the same - When possible, use a single host TSC value when computing the deadline for Xen timers in order to improve the accuracy of the timer emulation - Inject pending upcall events when the vCPU software-enables its APIC to fix a bug where an upcall can be lost (and to follow Xen's behavior) - Fall back to the slow path instead of warning if "fast" IRQ delivery of Xen events fails, e.g. if the guest has aliased xAPIC IDs RISC-V: - Support exception and interrupt handling in selftests - New self test for RISC-V architectural timer (Sstc extension) - New extension support (Ztso, Zacas) - Support userspace emulation of random number seed CSRs ARM: - Infrastructure for building KVM's trap configuration based on the architectural features (or lack thereof) advertised in the VM's ID registers - Support for mapping vfio-pci BARs as Normal-NC (vaguely similar to x86's WC) at stage-2, improving the performance of interacting with assigned devices that can tolerate it - Conversion of KVM's representation of LPIs to an xarray, utilized to address serialization some of the serialization on the LPI injection path - Support for _architectural_ VHE-only systems, advertised through the absence of FEAT_E2H0 in the CPU's ID register - Miscellaneous cleanups, fixes, and spelling corrections to KVM and selftests LoongArch: - Set reserved bits as zero in CPUCFG - Start SW timer only when vcpu is blocking - Do not restart SW timer when it is expired - Remove unnecessary CSR register saving during enter guest - Misc cleanups and fixes as usual Generic: - Clean up Kconfig by removing CONFIG_HAVE_KVM, which was basically always true on all architectures except MIPS (where Kconfig determines the available depending on CPU capabilities). It is replaced either by an architecture-dependent symbol for MIPS, and IS_ENABLED(CONFIG_KVM) everywhere else - Factor common "select" statements in common code instead of requiring each architecture to specify it - Remove thoroughly obsolete APIs from the uapi headers - Move architecture-dependent stuff to uapi/asm/kvm.h - Always flush the async page fault workqueue when a work item is being removed, especially during vCPU destruction, to ensure that there are no workers running in KVM code when all references to KVM-the-module are gone, i.e. to prevent a very unlikely use-after-free if kvm.ko is unloaded - Grab a reference to the VM's mm_struct in the async #PF worker itself instead of gifting the worker a reference, so that there's no need to remember to *conditionally* clean up after the worker Selftests: - Reduce boilerplate especially when utilize selftest TAP infrastructure - Add basic smoke tests for SEV and SEV-ES, along with a pile of library support for handling private/encrypted/protected memory - Fix benign bugs where tests neglect to close() guest_memfd files" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (246 commits) selftests: kvm: remove meaningless assignments in Makefiles KVM: riscv: selftests: Add Zacas extension to get-reg-list test RISC-V: KVM: Allow Zacas extension for Guest/VM KVM: riscv: selftests: Add Ztso extension to get-reg-list test RISC-V: KVM: Allow Ztso extension for Guest/VM RISC-V: KVM: Forward SEED CSR access to user space KVM: riscv: selftests: Add sstc timer test KVM: riscv: selftests: Change vcpu_has_ext to a common function KVM: riscv: selftests: Add guest helper to get vcpu id KVM: riscv: selftests: Add exception handling support LoongArch: KVM: Remove unnecessary CSR register saving during enter guest LoongArch: KVM: Do not restart SW timer when it is expired LoongArch: KVM: Start SW timer only when vcpu is blocking LoongArch: KVM: Set reserved bits as zero in CPUCFG KVM: selftests: Explicitly close guest_memfd files in some gmem tests KVM: x86/xen: fix recursive deadlock in timer injection KVM: pfncache: simplify locking and make more self-contained KVM: x86/xen: remove WARN_ON_ONCE() with false positives in evtchn delivery KVM: x86/xen: inject vCPU upcall vector when local APIC is enabled KVM: x86/xen: improve accuracy of Xen timers ...

We got some more devm helpers and we seem to be going in the direction of "just turn this stuff on already and leave me alone!" with the addition of a devm_clk_bulk_get_all_enable() API. I'm hoping that we can make that into a pmdomain that drivers attach instead, but this API should help drivers simplify in the meantime. Outside of the devm wrappers, we've got the usual clk driver updates that are dominated by the major phone SoC vendors (Samsung and Qualcomm) and the non-critical driver fixes for things like incorrect topology descriptions and wrong registers or bit fields. More details are below, but I'd say that it looks pretty ordinary. The only thing that really jumps out at me is the Renesas clk driver that's ignoring clks that are assigned to remote processors in DeviceTree. That's a new feature that they're using to avoid marking clks as CLK_IGNORE_UNUSED based on the configuration of the system.

2024-03-15Merge patch series "riscv: mm: Extend mappable memory up to hint address"Palmer Dabbelt1-11/+5
Charlie Jenkins <charlie@rivosinc.com> says: On riscv, mmap currently returns an address from the largest address space that can fit entirely inside of the hint address. This makes it such that the hint address is almost never returned. This patch raises the mappable area up to and including the hint address. This allows mmap to often return the hint address, which allows a performance improvement over searching for a valid address as well as making the behavior more similar to other architectures. Note that a previous patch introduced stronger semantics compared to other architectures for riscv mmap. On riscv, mmap will not use bits in the upper bits of the virtual address depending on the hint address. On other architectures, a random address is returned in the address space requested. On all architectures the hint address will be returned if it is available. This allows riscv applications to configure how many bits in the virtual address should be left empty. This has the two benefits of being able to request address spaces that are smaller than the default and doesn't require the application to know the page table layout of riscv. * b4-shazam-merge: docs: riscv: Define behavior of mmap selftests: riscv: Generalize mm selftests riscv: mm: Use hint address in mmap if available Link: https://lore.kernel.org/r/20240130-use_mmap_hint_address-v3-0-8a655cfa8bcb@rivosinc.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>

Raw NAND The main series brought is an update of the Broadcom support to support all BCMBCA SoCs and their specificity (ECC, write protection, configuration straps), plus a few misc fixes and changes in the main driver. Device tree updates are also part of this PR, initially because of a misunderstanding on my side. The STM32_FMC2 controller driver is also upgraded to properly support MP1 and MP25 SoCs. A new compatible is added for an Atmel flavor. Among all these feature changes, there is as well a load of continuous read related fixes, avoiding more corner conditions and clarifying the logic. Finally a few miscellaneous fixes are made to the core, the lpx32xx_mlc, fsl_lbc, Meson and Atmel controller driver, as well as final one in the Hynix vendor driver. SPI-NAND The ESMT support has been extended to match 5 bytes ID to avoid collisions. Winbond support on its side receives support for W25N04KV chips.

The series is "mm/zswap: optimize the scalability of zswap rb-tree". - Chengming Zhou has also provided the series "mm/zswap: optimize zswap lru list" which provides measurable runtime benefits in some swap-intensive situations. - And Chengming Zhou further optimizes zswap in the series "mm/zswap: optimize for dynamic zswap_pools". Measured improvements are modest. - zswap cleanups and simplifications from Yosry Ahmed in the series "mm: zswap: simplify zswap_swapoff()". - In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has contributed several DAX cleanups as well as adding a sysfs tunable to control the memmap_on_memory setting when the dax device is hotplugged as system memory. - Johannes Weiner has added the large series "mm: zswap: cleanups", which does that. - More DAMON work from SeongJae Park in the series "mm/damon: make DAMON debugfs interface deprecation unignorable" "selftests/damon: add more tests for core functionalities and corner cases" "Docs/mm/damon: misc readability improvements" "mm/damon: let DAMOS feeds and tame/auto-tune itself" - In the series "mm/mempolicy: weighted interleave mempolicy and sysfs extension" Rakie Kim has developed a new mempolicy interleaving policy wherein we allocate memory across nodes in a weighted fashion rather than uniformly.

Mainly targeted at arm64, this significantly speeds up fork() when the process has a large number of pte-mapped folios. - David Hildenbrand also gets in on the THP pte batching game in his series "mm/memory: optimize unmap/zap with PTE-mapped THP". It implements batching during munmap() and other pte teardown situations. The microbenchmark improvements are nice. - And in the series "Transparent Contiguous PTEs for User Mappings" Ryan Roberts further utilizes arm's pte's contiguous bit ("contpte mappings"). Kernel build times on arm64 improved nicely. Ryan's series "Address some contpte nits" provides some followup work. - In the series "mm/hugetlb: Restore the reservation" Breno Leitao has fixed an obscure hugetlb race which was causing unnecessary page faults. He has also added a reproducer under the selftest code. - In the series "selftests/mm: Output cleanups for the compaction test", Mark Brown did what the title claims. - Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring". - Even more zswap material from Nhat Pham. The series "fix and extend zswap kselftests" does as claimed. - In the series "Introduce cpu_dcache_is_aliasing() to fix DAX regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in our handling of DAX on archiecctures which have virtually aliasing data caches. The arm architecture is the main beneficiary. - Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic improvements in worst-case mmap_lock hold times during certain userfaultfd operations. - Some page_owner enhancements and maintenance work from Oscar Salvador in his series "page_owner: print stacks and their outstanding allocations" "page_owner: Fixup and cleanup" - Uladzislau Rezki has contributed some vmalloc scalability improvements in his series "Mitigate a vmap lock contention". It realizes a 12x improvement for a certain microbenchmark. - Some kexec/crash cleanup work from Baoquan He in the series "Split crash out from kexec and clean up related config items". - Some zsmalloc maintenance work from Chengming Zhou in the series "mm/zsmalloc: fix and optimize objects/page migration" "mm/zsmalloc: some cleanup for get/set_zspage_mapping()" - Zi Yan has taught the MM to perform compaction on folios larger than order=0. This a step along the path to implementaton of the merging of large anonymous folios. The series is named "Enable >0 order folio memory compaction". - Christoph Hellwig has done quite a lot of cleanup work in the pagecache writeback code in his series "convert write_cache_pages() to an iterator". - Some modest hugetlb cleanups and speedups in Vishal Moola's series "Handle hugetlb faults under the VMA lock". - Zi Yan has changed the page splitting code so we can split huge pages into sizes other than order-0 to better utilize large folios. The series is named "Split a folio to any lower order folios". - David Hildenbrand has contributed the series "mm: remove total_mapcount()", a cleanup. - Matthew Wilcox has sought to improve the performance of bulk memory freeing in his series "Rearrange batched folio freeing". - Gang Li's series "hugetlb: parallelize hugetlb page init on boot" provides large improvements in bootup times on large machines which are configured to use large numbers of hugetlb pages. - Matthew Wilcox's series "PageFlags cleanups" does that. - Qi Zheng's series "minor fixes and supplement for ptdesc" does that also. S390 is affected. - Cleanups to our pagemap utility functions from Peter Xu in his series "mm/treewide: Replace pXd_large() with pXd_leaf()". - Nico Pache has fixed a few things with our hugepage selftests in his series "selftests/mm: Improve Hugepage Test Handling in MM Selftests". - Also, of course, many singleton patches to many things.

Stephen reported that an htmldocs build hit: Documentation/ABI/testing/debugfs-cxl:38: ERROR: Unexpected indentation. It turns out that line was fine but the tool was unhappy about some line breaks in the table of values to error types. It turns out that: make V=1 SPHINXDIRS="admin-guide" htmldocs ...can not be used to get more info about what is behind a documentation build error. It was only pure luck that reflowing the text resulted in an error message that seemed a imply a problem later on with line breaks around the table.

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "The biggest feature is the locking overhaul. Up until now the synchronization in the GPIO subsystem was broken. There was a single spinlock "protecting" multiple data structures but doing it wrong (as evidenced by several places where it would be released when a sleeping function was called and then reacquired without checking the protected state). We tried to use an RW semaphore before but the main issue with GPIO is that we have drivers implementing the interfaces in both sleeping and non-sleeping ways as well as user-facing interfaces that can be called both from process as well as atomic contexts. Both ends converge in the same code paths that can use neither spinlocks nor mutexes. The only reasonable way out is to use SRCU and go mostly lockless. To that end: we add several SRCU structs in relevant places and use them to assure consistency between API calls together with atomic reads and writes of GPIO descriptor flags where it makes sense. This code has spent several weeks in next and has received several fixes in the first week or two after which it stabilized nicely. The GPIO subsystem is now resilient to providers being suddenly unbound. We managed to also remove the existing character device RW semaphore and the obsolete global spinlock. Other than the locking rework we have one new driver (for Chromebook EC), much appreciated documentation improvements from Kent and the regular driver improvements, DT-bindings updates and GPIOLIB core tweaks. Serialization rework: - use SRCU to serialize access to the global GPIO device list, to GPIO device structs themselves and to GPIO descriptors - make the GPIO subsystem resilient to the GPIO providers being unbound while the API calls are in progress - don't dereference the SRCU-protected chip pointer if the information we need can be obtained from the GPIO device structure - move some of the information contained in struct gpio_chip to struct gpio_device to further reduce the need to dereference the former - pass the GPIO device struct instead of the GPIO chip to sysfs callback to, again, reduce the need for accessing the latter - get GPIO descriptors from the GPIO device, not from the chip for the same reason - allow for mostly lockless operation of the GPIO driver API: assure consistency with SRCU and atomic operations - remove the global GPIO spinlock - remove the character device RW semaphore Core GPIOLIB: - constify pointers in GPIO API where applicable - unify the GPIO counting APIs for ACPI and OF - provide a macro for iterating over all GPIOs, not only the ones that are requested - remove leftover typedefs - pass the consumer device to GPIO core in devm_fwnode_gpiod_get_index() for improved logging - constify the GPIO bus type - don't warn about removing GPIO chips with descriptors still held by users as we can now handle this situation gracefully - remove unused logging helpers - unexport functions that are only used internally in the GPIO subsystem - set the device type (assign the relevant struct device_type) for GPIO devices New drivers: - add the ChromeOS EC GPIO driver Driver improvements: - allow building gpio-vf610 with COMPILE_TEST as well as disabling it in menuconfig (before it was always built for i.MX cofigs) - count the number of EICs using the device properties instead of hard-coding it in gpio-eic-sprd - improve the device naming, extend the debugfs output and add lockdep asserts to gpio-sim DT bindings: - document the 'label' property for gpio-pca9570 - convert aspeed,ast2400-gpio bindings to DT schema - disallow unevaluated properties for gpio-mvebu - document a new model in renesas,rcar-gpio Documentation: - improve the character device kerneldocs in user-space headers - add proper documentation for the character device uAPI (both v1 and v2) - move the sysfs and gpio-mockup docs into the "obsolete" section - improve naming consistency for GPIO terms - clarify the line values description for sysfs - minor docs improvements - improve the driver API contract for setting GPIO direction - mark unsafe APIs as deprecated in kerneldocs and suggest replacements Other: - remove an obsolete test from selftests" * tag 'gpio-updates-for-v6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (79 commits) gpio: sysfs: repair export returning -EPERM on 1st attempt selftest: gpio: remove obsolete gpio-mockup test gpiolib: Deduplicate cleanup for-loop in gpiochip_add_data_with_key() dt-bindings: gpio: aspeed,ast2400-gpio: Convert to DT schema gpio: acpi: Make acpi_gpio_count() take firmware node as a parameter gpio: of: Make of_gpio_get_count() take firmware node as a parameter gpiolib: Pass consumer device through to core in devm_fwnode_gpiod_get_index() gpio: sim: use for_each_hwgpio() gpio: provide for_each_hwgpio() gpio: don't warn about removing GPIO chips with active users anymore gpio: sim: delimit the fwnode name with a ":" when generating labels gpio: sim: add lockdep asserts gpio: Add ChromeOS EC GPIO driver gpio: constify of_phandle_args in of_find_gpio_device_by_xlate() gpio: fix memory leak in gpiod_request_commit() gpio: constify opaque pointer "data" in gpio_device_find() gpio: cdev: fix a NULL-pointer dereference with DEBUG enabled gpio: uapi: clarify default_values being logical gpio: sysfs: fix inverted pointer logic gpio: don't let lockdep complain about inherently dangerous RCU usage ...

Now when we make sure that we won't enable LPM for external ports, we can always set the LPM policy to CONFIG_SATA_MOBILE_LPM_POLICY for internal ports. There is thus no longer any need for the board type board_ahci_low_power, so it can be removed. (As before, LPM features not supported by the HBA and/or the device will not be enabled, regardless of the LPM policy Kconfig) (Mario Limonciello) Note that the default CONFIG_SATA_MOBILE_LPM_POLICY value is still 0 (which will not try to enable any LPM features), however, most Linux distributions override this and set it to 3 (Medium power with DIPM). We intend to change the default to 3 in the coming cycles, but we will wait a cycle or two. - Add board type board_ahci_pcs_quirk and make all legacy Intel platforms use it. The Intel PCS quirk was being applied to basically all Intel platforms, which caused some issues (the device failing to come back after a reset), when being applied to newer Intel platforms where it shouldn't have been applied. New platforms can be added using board type board_ahci, which will not have the quirk applied (me) - Rename board_ahci_nosntf to board_ahci_pcs_quirk_no_sntf to more clearly highlight that it applies two different quirks (me) - Modify the ahci_broken_devslp() quirk to be implemented like all the other quirks (i.e. define a board type for the quirk) (me) - Drop unused board_ahci_noncq board type (me) - Rename board_ahci_nomsi to board_ahci_no_msi to match the other board types (me) - Make pata_parport_bus_type const (Ricardo B.

Export CXL helper functions in einj-cxl.c for getting/injecting available CXL protocol error types to sysfs under kernel/debug/cxl. The kernel/debug/cxl/einj_types file will print the available CXL protocol errors in the same format as the available_error_types file provided by the einj module. The kernel/debug/cxl/$dport_dev/einj_inject file is functionally the same as the error_type and error_inject files provided by the EINJ module, i.e.: writing an error type into $dport_dev/einj_inject will inject said error type into the CXL dport represented by $dport_dev.

git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab Pull slab updates from Vlastimil Babka: - Freelist loading optimization (Chengming Zhou) When the per-cpu slab is depleted and a new one loaded from the cpu partial list, optimize the loading to avoid an irq enable/disable cycle. This results in a 3.5% performance improvement on the "perf bench sched messaging" test. - Kernel boot parameters cleanup after SLAB removal (Xiongwei Song) Due to two different main slab implementations we've had boot parameters prefixed either slab_ and slub_ with some later becoming an alias as both implementations gained the same functionality (i.e. slab_nomerge vs slub_nomerge). In order to eventually get rid of the implementation-specific names, the canonical and documented parameters are now all prefixed slab_ and the slub_ variants become deprecated but still working aliases. - SLAB_ kmem_cache creation flags cleanup (Vlastimil Babka) The flags had hardcoded #define values which became tedious and error-prone when adding new ones. Assign the values via an enum that takes care of providing unique bit numbers. Also deprecate SLAB_MEM_SPREAD which was only used by SLAB, so it's a no-op since SLAB removal. Assign it an explicit zero value. The removals of the flag usage are handled independently in the respective subsystems, with a final removal of any leftover usage planned for the next release. - Misc cleanups and fixes (Chengming Zhou, Xiaolei Wang, Zheng Yejian) Includes removal of unused code or function parameters and a fix of a memleak. * tag 'slab-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: slab: remove PARTIAL_NODE slab_state mm, slab: remove memcg_from_slab_obj() mm, slab: remove the corner case of inc_slabs_node() mm/slab: Fix a kmemleak in kmem_cache_destroy() mm, slab, kasan: replace kasan_never_merge() with SLAB_NO_MERGE mm, slab: use an enum to define SLAB_ cache creation flags mm, slab: deprecate SLAB_MEM_SPREAD flag mm, slab: fix the comment of cpu partial list mm, slab: remove unused object_size parameter in kmem_cache_flags() mm/slub: remove parameter 'flags' in create_kmalloc_caches() mm/slub: remove unused parameter in next_freelist_entry() mm/slub: remove full list manipulation for non-debug slab mm/slub: directly load freelist from cpu partial slab in the likely case mm/slub: make the description of slab_min_objects helpful in doc mm/slub: replace slub_$params with slab_$params in slub.rst mm/slub: unify all sl[au]b parameters with "slab_$param" Documentation: kernel-parameters: remove noaliencache

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core & protocols: - Large effort by Eric to lower rtnl_lock pressure and remove locks: - Make commonly used parts of rtnetlink (address, route dumps etc) lockless, protected by RCU instead of rtnl_lock. - Add a netns exit callback which already holds rtnl_lock, allowing netns exit to take rtnl_lock once in the core instead of once for each driver / callback. - Remove locks / serialization in the socket diag interface. - Remove 6 calls to synchronize_rcu() while holding rtnl_lock. - Remove the dev_base_lock, depend on RCU where necessary. - Support busy polling on a per-epoll context basis. Poll length and budget parameters can be set independently of system defaults. - Introduce struct net_hotdata, to make sure read-mostly global config variables fit in as few cache lines as possible. - Add optional per-nexthop statistics to ease monitoring / debug of ECMP imbalance problems. - Support TCP_NOTSENT_LOWAT in MPTCP. - Ensure that IPv6 temporary addresses' preferred lifetimes are long enough, compared to other configured lifetimes, and at least 2 sec. - Support forwarding of ICMP Error messages in IPSec, per RFC 4301. - Add support for the independent control state machine for bonding per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled control state machine. - Add "network ID" to MCTP socket APIs to support hosts with multiple disjoint MCTP networks. - Re-use the mono_delivery_time skbuff bit for packets which user space wants to be sent at a specified time. Maintain the timing information while traversing veth links, bridge etc. - Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets. - Simplify many places iterating over netdevs by using an xarray instead of a hash table walk (hash table remains in place, for use on fastpaths). - Speed up scanning for expired routes by keeping a dedicated list. - Speed up "generic" XDP by trying harder to avoid large allocations. - Support attaching arbitrary metadata to netconsole messages. Things we sprinkled into general kernel code: - Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena). - Rework selftest harness to enable the use of the full range of ksft exit code (pass, fail, skip, xfail, xpass). Netfilter: - Allow userspace to define a table that is exclusively owned by a daemon (via netlink socket aliveness) without auto-removing this table when the userspace program exits. Such table gets marked as orphaned and a restarting management daemon can re-attach/regain ownership. - Speed up element insertions to nftables' concatenated-ranges set type. Compact a few related data structures. BPF: - Add BPF token support for delegating a subset of BPF subsystem functionality from privileged system-wide daemons such as systemd through special mount options for userns-bound BPF fs to a trusted & unprivileged application. - Introduce bpf_arena which is sparse shared memory region between BPF program and user space where structures inside the arena can have pointers to other areas of the arena, and pointers work seamlessly for both user-space programs and BPF programs. - Introduce may_goto instruction that is a contract between the verifier and the program. The verifier allows the program to loop assuming it's behaving well, but reserves the right to terminate it. - Extend the BPF verifier to enable static subprog calls in spin lock critical sections. - Support registration of struct_ops types from modules which helps projects like fuse-bpf that seeks to implement a new struct_ops type. - Add support for retrieval of cookies for perf/kprobe multi links. - Support arbitrary TCP SYN cookie generation / validation in the TC layer with BPF to allow creating SYN flood handling in BPF firewalls. - Add code generation to inline the bpf_kptr_xchg() helper which improves performance when stashing/popping the allocated BPF objects. Wireless: - Add SPP (signaling and payload protected) AMSDU support. - Support wider bandwidth OFDMA, as required for EHT operation. Driver API: - Major overhaul of the Energy Efficient Ethernet internals to support new link modes (2.5GE, 5GE), share more code between drivers (especially those using phylib), and encourage more uniform behavior.

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull hardening updates from Kees Cook: "As is pretty normal for this tree, there are changes all over the place, especially for small fixes, selftest improvements, and improved macro usability. Some header changes ended up landing via this tree as they depended on the string header cleanups. Also, a notable set of changes is the work for the reintroduction of the UBSAN signed integer overflow sanitizer so that we can continue to make improvements on the compiler side to make this sanitizer a more viable future security hardening option.

Pull SoC device tree updates from Arnd Bergmann: "There is very little going on with new SoC support this time, all the new chips are variations of others that we already support, and they are all based on ARMv8 cores: - Mediatek MT7981B (Filogic 820) and MT7988A (Filogic 880) are networking SoCs designed to be used in wireless routers, similar to the already supported MT7986A (Filogic 830). - NXP i.MX8DXP is a variant of i.MX8QXP, with two CPU cores less. These are used in many embedded and industrial applications. - Renesas R8A779G2 (R-Car V4H ES2.0) and R8A779H0 (R-Car V4M) are automotive SoCs. - TI J722S is another automotive variant of its K3 family, related to the AM62 series. There are a total of 7 new arm32 machines and 45 arm64 ones, including - Two Android phones based on the old Tegra30 chip - Two machines using Cortex-A53 SoCs from Allwinner, a mini PC and a SoM development board - A set-top box using Amlogic Meson G12A S905X2 - Eight embedded board using NXP i.MX6/8/9 - Three machines using Mediatek network router chips - Ten Chromebooks, all based on Mediatek MT8186 - One development board based on Mediatek MT8395 (Genio 1200) - Seven tablets and phones based on Qualcomm SoCs, most of them from Samsung. - A third development board for Qualcomm SM8550 (Snapdragon 8 Gen 2) - Three variants of the "White Hawk" board for Renesas automotive SoCs - Ten Rockchips RK35xx based machines, including NAS, Tablet, Game console and industrial form factors. - Three evaluation boards for TI K3 based SoCs The other changes are mainly the usual feature additions for existing hardware, cleanups, and dtc compile time fixes.
