If you're planning to cut final on Friday please consider pulling for the bnxt fix. A quick follow up to yesterday's PR. We got a regressions report for the bnxt patch as soon as it got to your tree. The ethtool fix is also good to have, although it's an older regression. Current release - regressions: - eth: bnxt_en: fix crash in bnxt_get_max_rss_ctx_ring() on older HW when user tries to decrease the ring count Previous releases - regressions: - ethtool: fix RSS setting, accept "no change" setting if the driver doesn't support the new features - eth: i40e: remove needless retries of NVM update, don't wait 20min when we know the firmware update won't succeed Signed-off-by: Jakub Kicinski <[email protected]>
I believe the fix for the 6.9 regression mentioned by Jakub in
the previous net PR already landed in your tree as leds revert.
I'm not aware of any other new pending regressions.
Including fixes from bpf and netfilter.
Current release - regressions:
- core: fix rc7's __skb_datagram_iter() regression

Obviously I should not have jinxed things by saying that my previous pull- request would be the last one for 6.10. So here is one more 6.10 fixes pull-request with a 1 liner fix for a dmi_system_id array in the toshiba_acpi driver not being terminated properly. Something which somehow has escaped detection since being introduced in 2022 until now. Regards, Hans platform-drivers-x86 for v6.10-6 Highlights: - Fix missing dmi_system_id array termination in toshiba_acpi introduced in 2022 The following is an automated git shortlog grouped by driver: toshiba_acpi: - Fix array out-of-bounds access

There's one fix for power management with Intel's e1000e here,
Thorsten tells us there's another problem that started in v6.9.
We're trying to wrap that up but I don't think it's blocking.

We have a series from Xiubo that adds support for additional access checks based on MDS auth caps which were recently made available to clients. This is needed to prevent scenarios where the MDS quietly discards updates that a UID-restricted client previously (wrongfully) acked to the user. Other than that, just a documentation fixup.

Hi, a few more updates, mostly stability fixes or user visible changes. - fix race in zoned mode during device replace that can lead to use-after-free - update return codes and lower message levels for quota rescan where it's causing false alerts - fix unexpected qgroup id reuse under some conditions - fix condition when looking up extent refs - add option norecovery (removed in 6.8), the intended replacements haven't been used and some aplications still rely on the old one - build warning fixes
Could you consider these extra patches for 6.10-rc1? The main ones are metadata API conversion to byte offsets by Al Viro. Since some of patches are also part of VFS "->bd_inode elimination" (and they were merged upstream days ago), I did a merge commit to resolve the dependency with the detailed description. Another patch gets rid of unnecessary memory allocation out of DEFLATE decompressor. The remaining one is a trivial cleanup. All commits have been in -next and no potential merge conflict is observed. Thanks, Gao Xiang Changes since last update: - Convert metadata APIs to byte offsets; - Avoid allocating DEFLATE streams unnecessarily; - Some erofs_show_options() cleanup.

Hi Wolfram, I removed Heiner's commit from the pull request because, as you found out, there is still one remaining usage of the I2C_CLASS_SPD macro. Only Christophe's cleanup is included here, and its description is in the git tag. Thanks, and sorry for the inconvenience that brought to this v2. Andi a cleanup in the Synquacer code removes the pclk from the global structure, as it is used only in the probe. Therefore, it is now declared locally.

Hi Wolfram, now that the dependencies are fixed and no error report has been sent on these two patches, I can finally send the second part of the i2c pull request. Thanks, Andi Removed the SPD class of i2c devices from the device core. Additionally, a cleanup in the Synquacer code removes the pclk from the global structure, as it is used only in the probe. Therefore, it is now declared locally.
These things missed the first round of updates as I was awaiting
clarification of readiness and of the consequences of the additional
warnings Arnd is enabling.
Thanks.
- A series ("kbuild: enable more warnings by default") from Arnd
Bergmann which enables a number of additional build-time warnings. We
fixed all the fallout which we could find, there may still be a few
stragglers.
- Samuel Holland has developed the series "Unified cross-architecture
kernel-mode FPU API". This does a lot of consolidation of
per-architecture kernel-mode FPU usage and enables the use of newer AMD
GPUs on RISC-V.
- Tao Su has fixed some selftests build warnings in the series
"Selftests: Fix compilation warnings due to missing _GNU_SOURCE
definition".
- This pull also includes a nilfs2 fixup from Ryusuke Konishi.

Staging driver changes for 6.10-rc1 Here is the big set of staging driver changes for 6.10-rc1. Not a lot of cleanups happening this kernel release, intern applications must be out of sync at the moment. But we did delete two drivers, wlan-ng and pi433, as they are no longer in use and the developers involved wanted them just gone entirely, allowing us to drop 19k lines from the tree. Other than the normal coding style cleanups here, there has been a lot of work on the vc04_services code, with the intent to finally get that out of staging hopefully soon. It's getting closer, which is nice to see. All of these have been in linux-next for a while with no reported issues. Signed-off-by: Greg Kroah-Hartman <[email protected]>

Please consider pulling, there is one patch for updating the tools/lib/ (edited) copy of rbtree.c and rbtree_augmented.h that is already in your tree, as I didn't notice that Andrew Morton had picked it until Stephen Rothwell mentioned it to me, no biggie, I think. Best regards, - Arnaldo perf tools fixes and improvements for v6.10: - Add Kan Liang to MAINTAINERS as a perf tools reviewer. - Add support for using the 'capstone' disassembler library in various tools, such as 'perf script' and 'perf annotate'. This is an alternative for the use of the 'xed' and 'objdump' disassemblers. - Data-type profiling improvements: Resolve types for a->b->c by backtracking the assignments until it finds DWARF info for one of those members Support for global variables, keeping a cache to speed up lookups. Handle the 'call' instruction, dealing with effects on registers and handling its return when tracking register data types. Handle x86's segment based addressing like %gs:0x28, to support things like per CPU variables, the stack canary, etc. Data-type profiling got big speedups when using capstone for disassembling. The objdump outoput parsing method is left as a fallback when capstone fails or isn't available. There are patches posted for 6.11 that to use a LLVM disassembler. Support event group display in the TUI when annotating types with --data-type, for instance to show memory load and store events for the data type fields. Optimize the 'perf annotate' data structures, reducing memory usage. Add a initial 'perf test' for 'perf annotate', checking that a target symbol appears on the output, specifying objdump via the command line, etc. - Integrate the shellcheck utility with the build of perf to allow catching shell problems early in areas such as 'perf test', 'perf trace' scrape scripts, etc. - Add 'uretprobe' variant in the 'perf bench uprobe' tool. - Add script to run instances of 'perf script' in parallel. - Allow parsing tracepoint names that start with digits, such as 9p/9p_client_req, etc. Make sure 'perf test' tests it even on systems where those tracepoints aren't available. Vendor Events: - Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand Ridge, Ice Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra Forest, Sky Lake X, Sky Lake and Snow Ridge X. Remove info metrics erroneously in TopdownL1. - Add AMD's Zen 5 core and uncore events and metrics. Those come from the "Performance Monitor Counters for AMD Family 1Ah Model 00h- 0Fh Processors" document, with events that capture information on op dispatch, execution and retirement, branch prediction, L1 and L2 cache activity, TLB activity, etc. - Mark L1D_CACHE_INVAL impacted by errata for ARM64's AmpereOne/AmpereOneX. Miscellaneous: - Sync header copies with the kernel sources. - Move some header copies used only for generating translation string tables for ioctl cmds and other syscall integer arguments to a new directory under tools/perf/beauty/, to separate from copies in tools/include/ that are used to build the tools. - Introduce scrape script for several syscall 'flags'/'mask' arguments. - Improve cpumap utilization, fixing up pairing of refcounts, using the right iterators (perf_cpu_map__for_each_cpu), etc. - Give more details about raw event encodings in 'perf list', show tracepoint encoding in the detailed output. - Refactor the DSOs handling code, reducing memory usage. - Document the BPF event modifier and add a 'perf test' for it. - Improve the event parser, better error messages and add further 'perf test's for it. - Add reference count checking to 'struct comm_str' and 'struct mem_info'. - Make ARM64's 'perf test' entries for the Neoverse N1 more robust. - Tweak the ARM64's Coresight 'perf test's. - Improve ARM64's CoreSight ETM version detection and error reporting. - Fix handling of symbols when using kcore. - Fix PAI (Processor Activity Instrumentation) counter names for s390 virtual machines in 'perf report'. - Fix -g/--call-graph option failure in 'perf sched timehist'. - Add LIBTRACEEVENT_DIR build option to allow building with libtraceevent installed in non-standard directories, such as when doing cross builds. - Various 'perf test' and 'perf bench' fixes. - Improve 'perf probe' error message for long C++ probe names.

- Switch read and write software bits for PUDs
- Add missing hardware bits for PUDs and PMDs
- Generate unwind information for C modules to fix GDB unwind
error for vDSO functions
- Create .build-id links for unstripped vDSO files to enable
vDSO debugging with symbols
- Use standard stack frame layout for vDSO generated stack frames
to manually walk stack frames without DWARF information
- Rework perf_callchain_user() and arch_stack_walk_user() functions
to reduce code duplication
- Skip first stack frame when walking user stack
- Add basic checks to identify invalid instruction pointers when
walking stack frames
- Introduce and use struct stack_frame_vdso_wrapper within vDSO user
wrapper code to automatically generate an asm-offset define. Also
use STACK_FRAME_USER_OVERHEAD instead of STACK_FRAME_OVERHEAD to
document that the code works with user space stack
- Clear the backchain of the extra stack frame added by the vDSO user
wrapper code. This allows the user stack walker to detect and skip
the non-standard stack frame. Without this an incorrect instruction
pointer would be added to stack traces.
- Rewrite psw_idle() function in C to ease maintenance and further
enhancements
- Remove get_vtimer() function and use get_cpu_timer() instead
- Mark psw variable in __load_psw_mask() as __unitialized to avoid
superfluous clearing of PSW
- Remove obsolete and superfluous comment about removed TIF_FPU flag
- Replace memzero_explicit() and kfree() with kfree_sensitive() to
fix warnings reported by Coccinelle
- Wipe sensitive data and all copies of protected- or secure-keys
from stack when an IOCTL fails
- Both do_airq_interrupt() and do_io_interrupt() functions set
CIF_NOHZ_DELAY flag. Move it in do_io_irq() to simplify the code
- Provide iucv_alloc_device() and iucv_release_device() helpers,
which can be used to deduplicate more or less identical IUCV
device allocation and release code in four different drivers
- Make use of iucv_alloc_device() and iucv_release_device()
helpers to get rid of quite some code and also remove a
cast to an incompatible function (clang W=1)
- There is no user of iucv_root outside of the core IUCV code left.
Therefore remove the EXPORT_SYMBOL
- __apply_alternatives() contains a runtime check which verifies
that the size of the to be patched code area is even. Convert
this to a compile time check
- Increase size of buffers for sending z/VM CP DIAGNOSE X'008'
commands from 128 to 240
- Do not accept z/VM CP DIAGNOSE X'008' commands longer than
maximally allowed
- Use correct defines IPL_BP_NVME_LEN and IPL_BP0_NVME_LEN instead
of IPL_BP_FCP_LEN and IPL_BP0_FCP_LEN ones to initialize NVMe
reIPL block on 'scp_data' sysfs attribute update
- Initialize the correct fields of the NVMe dump block, which
were confused with FCP fields
- Refactor macros for 'scp_data' (re-)IPL sysfs attribute to
reduce code duplication
- Introduce 'scp_data' sysfs attribute for dump IPL to allow tools
such as dumpconf passing additional kernel command line parameters
to a stand-alone dumper
- Rework the CPACF query functions to use the correct RRE or RRF
instruction formats and set instruction register fields correctly
- Instead of calling BUG() at runtime force a link error during
compile when a unsupported opcode is used with __cpacf_query()
or __cpacf_check_opcode() functions
- Fix a crash in ap_parse_bitmap_str() function on /sys/bus/ap/apmask
or /sys/bus/ap/aqmask sysfs file update with a relative mask value
- Fix "bindings complete" udev event which should be sent once all AP
devices have been bound to device drivers and again when unbind/bind
actions take place and all AP devices are bound again
- Facility list alt_stfle_fac_list is nowhere used in the decompressor,
therefore remove it there
- Remove custom kprobes insn slot allocator in favour of the standard
module_alloc() one, since kernel image and module areas are located
within 4GB
- Use kvcalloc() instead of kvmalloc_array() in zcrypt driver to avoid
calling memset() with a large byte count and get rid of the sparse
warning as result

soc: devicetree updates for v6.10, part 2 This is a follow-up to an earlier pull request for device tree changes, as three platform maintainers sent their contents too late to be included in the main set, but had not caused any further problems since then: - The Amlogic platform now containts support for two new SoC types, the A4 and A5 chips for audio applications. Both come with a reference board, and one more dts file gets addded for the combination of the MNT Reform Laptop with the BPI-CM4 CPU module - The ASpeed platform adds support for six addititional server platforms that use ast2500 or ast2600 as their BMC, while another one gets removed. - The RISC-V platforms from Microchip, Starfive and and T-HEAD get additional features for existing hardware, plus the addition of the Milk-V Mars based on the StarFive VisionFive v2 board.
Could you please consider this pull reuqest?
Thanks,
f2fs update for 6.10-rc1
In this round, we've tried to address some performance issues on zoned storage
such as direct IO and write_hints. In addition, we've migrated some IO paths
using folio. Meanwhile, there are multiple bug fixes in the compression paths,
sanity check conditions, and error handlers.
Enhancement:
- allow direct io of pinned files for zoned storage
- assign the write hint per stream by default
- convert read paths and test_writeback to folio
- avoid allocating WARM_DATA segment for direct IO
Bug fix:
- fix false alarm on invalid block address
- fix to add missing iput() in gc_data_segment()
- fix to release node block count in error path of f2fs_new_node_page()
- compress: don't allow unaligned truncation on released compress inode
- compress: fix to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock
- compress: fix error path of inc_valid_block_count()
- compress: fix to update i_compr_blocks correctly
- fix block migration when section is not aligned to pow2
- don't trigger OPU on pinfile for direct IO
- fix to do sanity check on i_xattr_nid in sanity_check_inode()
- write missing last sum blk of file pinning section
- clear writeback when compression failed
- fix to adjust appropirate defragment pg_end
As usual, there are several minor code clean-ups, and fixes to manage missing
corner cases in the error paths.
I've provided the simplified diffstat from a temporary merge branch to avoid the noise of merging QAT dependencies from a branch provided by Herbert. The dependencies were already merged in commit 84c7d76b5ab6 Thanks, Alex VFIO updates for v6.10-rc1 - The vfio fsl-mc bus driver has become orphaned. We'll consider removing it in future releases if a new maintainer isn't found. (Alex Williamson) - Improved usage of opaque data in vfio-pci INTx handling, avoiding lookups of the eventfd through the interrupt and irqfd runtime paths. (Alex Williamson) - Resolve an error path memory leak introduced in vfio-pci interrupt code. (Ye Bin) - Addition of interrupt support for vfio devices exposed on the CDX bus, including a new MSI allocation helper and export of existing helpers for MSI alloc and free. (Nipun Gupta) - A new vfio-pci variant driver supporting migration of Intel QAT VF devices for the GEN4 PFs. (Xin Zeng & Yahui Cao) - Resolve a possibly circular locking dependency in vfio-pci by avoiding copy_to_user() from a PCI bus walk callback. (Alex Williamson) - Trivial docs update to remove a duplicate semicolon. (Foryun Ma)
Note that the the dma sync optimizations reach into the networking code and promptly caused a conflict where the netdev tree constifies the page argument to page_pool_dma_sync_for_device and this tree renames that function to page_pool_dma_sync_for_device. The dma-mapping version of the merge just works, but you might want to pick the contification manually if you think it is useful. dma-mapping updates for Linux 6.10 - optimize DMA sync calls when they are no-ops (Alexander Lobakin) - fix swiotlb padding for untrusted devices (Michael Kelley) - add documentation for swiotb (Michael Kelley)

bitmap patches for 6.10 Hi Linus, - topology_span_sane() optimization from Kyle Meyer; - fns() rework from Kuan-Wei Chiu (used in cpumask_local_spread() and other places); and - headers cleanup from Andy. This also adds a MAINTAINERS record for bitops API as it's unattended, and I'd like to follow it closer. v2: drop binary fns(). Thanks, Yury
Here is Arunpravin's second fix for the buddy allocator warnings you have been seeing, hopefully this is the end of that, and thanks for your patience. Regards, Dave. drm-next-2024-05-20: drm urgent (the 2nd) for 6.10-rc1 buddy: - fix WARN_ONs during force merge drm urgent (the 2nd) for 6.10-rc1 buddy: - fix WARN_ONs during force merge
I'm seeing a little conflict in init/main.c - addition of a code comment. Mainly singleton patches, documented in their respective changelogs. Notable series include: - Some maintenance and performance work for ocfs2 in Heming Zhao's series "improve write IO performance when fragmentation is high". - Some ocfs2 bugfixes from Su Yue in the series "ocfs2 bugs fixes exposed by fstests". - kfifo header rework from Andy Shevchenko in the series "kfifo: Clean up kfifo.h". - GDB script fixes from Florian Rommel in the series "scripts/gdb: Fixes for $lx_current and $lx_per_cpu". - After much discussion, a coding-style update from Barry Song explaining one reason why inline functions are preferred over macros. The series is "codingstyle: avoid unused parameters for a function-like macro".
Turbostat 2024.05.10 update since 2024.04.08: Survive sparse die id's seen in Linux-6.9. Handle clustered-uncore topology in new/upcoming hardware. For non-root use, add ability to see software C-state counters. Enable reading core and package hardware cstate via perf, and prefer perf over the MSR driver access for these counters.
kgdb patches for 6.10 Nine patches this cycle and they split into just three topics: 1. Adopt coccinelle's recommendation to adopt str_plural(). 2. A set of seven patches to refactor kdb_read() to improve both code clarity and it's discipline with respect to fixed size buffers. This isn't just a refactor. Between them these also fix a cursor movement redraw problem and two buffer overflows (one latent and one real, albeit difficult to tickle). 3. Fix an NMI-safety problem when enqueuing kdb's keyboard reset code. I wrote eight of the nine patches in this collection so many thanks to Doug Anderson for the reviews. The changes that affects drivers/tty/serial is acked by Greg KH. Signed-off-by: Daniel Thompson <[email protected]>

Specific for timerlat: - Improves the output of timerlat top by adding a missing \n, and by avoiding printing color-formatting characters where they are translated to regular characters. - Improves timerlat auto-analysis output by replacing '\t' with spaces to avoid copy-and-paste issues when reporting problems. - For timerlat, make the user-space (-u) option the default, as it is the most complete test. Add a -k option to use the in-kernel workload. - On timerlat top and hist, add a summary with the overall results. For instance, the minimum value for all CPUs, the overall average and the maximum value from all CPUs. - timerlat hist was printing initial values (i.e., 0 as max, and ~0 as min) if the trace stopped before the first Ret-User event. This problem was fixed by printing the " - " no value string to the output if that was the case. For all RTLA tools: - Add a --warm-up <seconds> option, allowing the workload to run for <seconds> before starting to collect results. - Add a --trace-buffer-size option, allowing the user to set the tracing buffer size for -t option. This option is mainly useful for reducing the trace file. Now rtla depends on libtracefs >= 1.6. - Fix the -t [trace_file] parsing, now it does not require the '=' before the option parameter, and better handles the multiple ways a user can pass the trace_file.txt trace-tools-v6.10 Tag SHA1: 2e2ffd01fe2dd06c66621bf7404beb31beb50ea1 Head SHA1: 59c22f70b2951d81de410d477ae536ba951b4f37
Hi Linus, Just a few changes this time. All patches have been in -next for 7 weeks except for the dt-binding change, which I apparently forgot to push out. I still included it in the pull request, since it is just a simple documentation fix. There should be no merge conflicts. power supply and reset changes for the 6.10 series * core: simplify POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR handling * test-power: add POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR support * chrome EC drivers: add ID based probing * bq27xxx: simplify update loop to reduce I2C traffic * max8903 binding: fix GPIO polarity description
NFSD 6.10 Release Notes This is a light release containing mostly optimizations, code clean- ups, and minor bug fixes. This development cycle has focused on non- upstream kernel work: 1. Continuing to build upstream CI for NFSD, based on kdevops 2. Backporting NFSD filecache-related fixes to selected LTS kernels One notable new feature in v6.10 NFSD is the addition of a new netlink protocol dedicated to configuring NFSD. A new user space tool, nfsdctl, is to be added to nfs-utils. Lots more to come here. As always I am very grateful to NFSD contributors, reviewers, testers, and bug reporters who participated during this cycle.
I usually like to send you a pull early, but things got a bit delayed for me. Nonetheless, these three small commits have been cooking in -next for a while and I don't expect much trouble. This pull has one new feature: - The vmgenid driver can now be bound using device tree, rather than just ACPI. The improvement, from Sudan, lets Amazon's Firecracker VMM make use of the virtual device without having to expose an otherwise unused ACPI stack in their "micro VM". Thanks, Jason Random number generator updates for Linux 6.10-rc1.
You will see conflicts in 4 files. All of them are properly resolved in linux-next. After merging this pull request, just in case, please run $ git grep '$(srctree)/$(src)' If you get a hit, please replace $(srctree)/$(src) with $(src). My commit b1992c3772e6 needs to consistently replace $(srctree)/$(src), but I cannot touch in-flight patches merged in other subsystems. The following are the merge conflicts I am aware of: [1] drivers/gpu/drm/msm/Makefile conflict between 0fddd045f88e between b1992c3772e6 addressed by: https://lore.kernel.org/all/[email protected]/ [2] drivers/misc/lkdtm/Makefile conflict between fb28a8862dc4 between 7f7f6f7ad654 addressed by: https://lore.kernel.org/all/[email protected]/ [3] drivers/net/wireless/intel/iwlwifi/mvm/Makefile conflict between 2887af4d22f9 and b1992c3772e6 addressed by: https://lore.kernel.org/all/[email protected]/ [4] rust/Makefile conflict between 11795ae4cc43 and b1992c3772e6 addressed by: https://lore.kernel.org/all/[email protected]/ Thank you. Kbuild updates for v6.10 - Avoid 'constexpr', which is a keyword in C23 - Allow 'dtbs_check' and 'dt_compatible_check' run independently of 'dt_binding_check' - Fix weak references to avoid GOT entries in position-independent code generation - Convert the last use of 'optional' property in arch/sh/Kconfig - Remove support for the 'optional' property in Kconfig - Remove support for Clang's ThinLTO caching, which does not work with the .incbin directive - Change the semantics of $(src) so it always points to the source directory, which fixes Makefile inconsistencies between upstream and downstream - Fix 'make tar-pkg' for RISC-V to produce a consistent package - Provide reasonable default coverage for objtool, sanitizers, and profilers - Remove redundant OBJECT_FILES_NON_STANDARD, KASAN_SANITIZE, etc. - Remove the last use of tristate choice in drivers/rapidio/Kconfig - Various cleanups and fixes in Kconfig
There is a small and easy to resolve conflict with these changes in
drivers/acpi/scan.c. Please take the version that comes from the iommu
tree. With this being said:

tracing ring buffer updates for v6.10:
- Add ring_buffer memory mappings
The tracing ring buffer was created based on being mostly used with the
splice system call. It is broken up into page ordered sub-buffers and the
reader swaps a new sub-buffer with an existing sub-buffer that's part
of the write buffer. It then has total access to the swapped out
sub-buffer and can do copyless movements of the memory into other mediums
(file system, network, etc).
The buffer is great for passing around the ring buffer contents in the
kernel, but is not so good for when the consumer is the user space task
itself.
A new interface is added that allows user space to memory map the ring
buffer. It will get all the write sub-buffers as well as reader sub-buffer
(that is not written to). It can send an ioctl to change which sub-buffer
is the new reader sub-buffer.
The ring buffer is read only to user space. It only needs to call the
ioctl when it is finished with a sub-buffer and needs a new sub-buffer
that the writer will not write over.
A self test program was also created for testing and can be used as
an example for the interface to user space. The libtracefs (external
to the kernel) also has code that interacts with this, although it is
disabled until the interface is in a official release. It can be enabled
by compiling the library with a special flag. This was used for testing
applications that perform better with the buffer being mapped.
Memory mapped buffers have limitations. The main one is that it can not be
used with the snapshot logic. If the buffer is mapped, snapshots will be
disabled. If any logic is set to trigger snapshots on a buffer, that
buffer will not be allowed to be mapped.
- Changes since last pull request:
https://lore.kernel.org/all/[email protected]/
All the pages of the ring buffer are mapped at the mmap() system call
instead of paging them in when they are accessed. The VMA page flags
have been updated and the mappings are done via vm_insert_pages().
I'd like to thank both Mike Rapoport and David Hildenbrand for their
review of these patches to make sure they are doing things correctly
from a memory management point of view.

tracing cleanups for v6.10:
- Removed unused ftrace_direct_funcs variables
- Fix a possible NULL pointer dereference race in eventfs
- Update do_div() usage in trace event benchmark test
- Speedup direct function registration with asynchronous RCU callback.
The synchronization was done in the registration code and this
caused delays when registering direct callbacks. Move the freeing
to a call_rcu() that will prevent delaying of the registering.
- Replace simple_strtoul() usage with kstrtoul()

This PR mainly brings IOCTL control to Landlock, contributed by Günther Noack. This also adds him as a Landlock reviewer, and fixes an issue in the sample. master branch. The kernel code has been tested in the latest linux-next releases for a few weeks, but I rebased it on v6.9 to avoid a merge conflict because of the recent Kselftest fixes. syzkaller has also been patched to know about this new access right.

sysctl changes for v6.10-rc1
Summary
* Removed sentinel elements from ctl_table structs in kernel/*
Removing sentinels in ctl_table arrays reduces the build time size and
runtime memory consumed by ~64 bytes per array. Removals for net/, io_uri=
ng/,
mm/, ipc/ and security/ are set to go into mainline through their respect=
ive
subsystems making the next release the most likely place where the final
series that removes the check for proc_name =3D=3D NULL will land. This P=
R adds
to removals already in arch/, drivers/ and fs/.
* Adjusted ctl_table definitions and references to allow constification
Adjustments:
- Removing unused ctl_table function arguments
- Moving non-const elements from ctl_table to ctl_table_header
- Making ctl_table pointers const in ctl_table_root structure
Making the static ctl_table structs const will increase safety by keeping=
the
pointers to proc_handler functions in .rodata. Though no ctl_tables where
made const in this PR, the ground work for making that possible has start=
ed
with these changes sent by Thomas Wei?schuh.
Testing
* These changes went into linux-next after v6.9-rc4; giving it a good month=
of
testing.
This is the MTD PR for v6.10-rc1. Thanks, Miqu=C3=A8l * MTD Simon Glass wanted to support binman's output properties in order to check their validity using the binding checks and proposed changes with the missing properties as well as a binman compatible. Krzysztof Kozlowski on his side shared a new yaml for describing Samsung's OneNAND interface. The interface with NVMEM has also been slightly improved/fixed, especially now that OTP are also supported in the NAND subsystem. Along with these changes, small cleanups have also been contributed around ID tables, structure sizes, arithmetic checks and comments. * Raw NAND subsystem Two small fixes, one in the Hynix vendor code for properly returning an error which might have been ignored and another in the Davinci driver to properly synchronize the controller with the gpio domain. * SPI NOR subsystem SPI NOR now uses div_u64() instead of div64_u64() in places where the divisor is 32 bits. Many 32 bit architectures can optimize this variant better than a full 64 bit divide.
dia/v6.10-1 For: - New V4L2 ioctl VIDIOC_REMOVE_BUFS; - experimental support for using generic metaformats on V4L2 core; - New drivers: Intel IPU6 controller driver, Broadcom BCM283x/BCM271x; - More cleanups at atomisp driver; - Usual bunch of driver cleanups, improvements and fixes.

Probes updates for v6.10: - tracing/probes: Adding new pseudo-types %pd and %pD support for dumping dentry name from 'struct dentry *' and file name from 'struct file *'. - uprobes: Some performance optimizations have been done. . Speed up the BPF uprobe event by delaying the fetching of the uprobe event arguments that are not used in BPF. . Avoid locking by speculatively checking whether uprobe event is valid. . Reduce lock contention by using read/write_lock instead of spinlock for uprobe list operation. This improved BPF uprobe benchmark result 43% on average. - rethook: Removes non-fatal warning messages when tracing stack from BPF and skip rcu_is_watching() validation in rethook if possible. - objpool: Optimizing objpool (which is used by kretprobes and fprobe as rethook backend storage) by inlining functions and avoid caching nr_cpu_ids because it is a const value. - fprobe: Add entry/exit callbacks types (code cleanup) - kprobes: Check ftrace was killed in kprobes if it uses ftrace. probes-v6.10 Tag SHA1: 9c42dca969de36a7aaa9573844a863bb306dcafc Head SHA1: 1a7d0890dd4a502a202aaec792a6c04e6e049547
workqueue: Changes for v6.10 - Work items can now be disabled and enabled, and cancel_work_sync() and disable_work() can be called form atomic contexts for BH work items. This closes feature gap with tasklet and should allow converting all existing tasklet users to BH workqueues. - Improve pool sharing for unbound workqueues with strict affinity. - Misc changes including doc updates, improved debug annotations and cleanups.
cgroup: Changes for v6.10 - The locking around cpuset hotplug processing has always been a bit of mess which was worked around by making hotplug processing asynchronous. The asynchronity isn't great and led to other issues. We tried to make the behavior synchronous a while ago but that led to lockdep splats. Waiman took another stab at cleaning up and making it synchronous. The patch has been in -next for well over a month and there haven't been any complaints, so fingers crossed. - Tracepoints added to help understanding rstat lock contentions. - A bunch of minor changes - doc updates, code cleanups and selftests.
ARM: * Move a lot of state that was previously stored on a per vcpu basis into a per-CPU area, because it is only pertinent to the host while the vcpu is loaded. This results in better state tracking, and a smaller vcpu structure. * Add full handling of the ERET/ERETAA/ERETAB instructions in nested virtualisation. The last two instructions also require emulating part of the pointer authentication extension. As a result, the trap handling of pointer authentication has been greatly simplified. * Turn the global (and not very scalable) LPI translation cache into a per-ITS, scalable cache, making non directly injected LPIs much cheaper to make visible to the vcpu. * A batch of pKVM patches, mostly fixes and cleanups, as the upstreaming process seems to be resuming. Fingers crossed! * Allocate PPIs and SGIs outside of the vcpu structure, allowing for smaller EL2 mapping and some flexibility in implementing more or less than 32 private IRQs. * Purge stale mpidr_data if a vcpu is created after the MPIDR map has been created. * Preserve vcpu-specific ID registers across a vcpu reset. * Various minor cleanups and improvements. LoongArch: * Add ParaVirt IPI support. * Add software breakpoint support. * Add mmio trace events support. RISC-V: * Support guest breakpoints using ebreak * Introduce per-VCPU mp_state_lock and reset_cntx_lock * Virtualize SBI PMU snapshot and counter overflow interrupts * New selftests for SBI PMU and Guest ebreak * Some preparatory work for both TDX and SNP page fault handling. This also cleans up the page fault path, so that the priorities of various kinds of fauls (private page, no memory, write to read-only slot, etc.) are easier to follow. x86: * Minimize amount of time that shadow PTEs remain in the special REMOVED_SPTE state. This is a state where the mmu_lock is held for reading but concurrent accesses to the PTE have to spin; shortening its use allows other vCPUs to repopulate the zapped region while the zapper finishes tearing down the old, defunct page tables. * Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID field, which is defined by hardware but left for software use. This lets KVM communicate its inability to map GPAs that set bits 51:48 on hosts without 5-level nested page tables. Guest firmware is expected to use the information when mapping BARs; this avoids that they end up at a legal, but unmappable, GPA. * Fixed a bug where KVM would not reject accesses to MSR that aren't supposed to exist given the vCPU model and/or KVM configuration. * As usual, a bunch of code cleanups. x86 (AMD): * Implement a new and improved API to initialize SEV and SEV-ES VMs, which will also be extendable to SEV-SNP. The new API specifies the desired encryption in KVM_CREATE_VM and then separately initializes the VM. The new API also allows customizing the desired set of VMSA features; the features affect the measurement of the VM's initial state, and therefore enabling them cannot be done tout court by the hypervisor. While at it, the new API includes two bugfixes that couldn't be applied to the old one without a flag day in userspace or without affecting the initial measurement. When a SEV-ES VM is created with the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are rejected once the VMSA has been encrypted. Also, the FPU and AVX state will be synchronized and encrypted too. * Support for GHCB version 2 as applicable to SEV-ES guests. This, once more, is only accessible when using the new KVM_SEV_INIT2 flow for initialization of SEV-ES VMs. x86 (Intel): * An initial bunch of prerequisite patches for Intel TDX were merged. They generally don't do anything interesting. The only somewhat user visible change is a new debugging mode that checks that KVM's MMU never triggers a #VE virtualization exception in the guest. * Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig VM-Exit to L1, as per the SDM. Generic: * Use vfree() instead of kvfree() for allocations that always use vcalloc() or __vcalloc(). * Remove .change_pte() MMU notifier - the changes to non-KVM code are small and Andrew Morton asked that I also take those through the KVM tree. The callback was only ever implemented by KVM (which was also the original user of MMU notifiers) but it had been nonfunctional ever since calls to set_pte_at_notify were wrapped with invalidate_range_start and invalidate_range_end... in 2012. Selftests: * Enhance the demand paging test to allow for better reporting and stressing of UFFD performance. * Convert the steal time test to generate TAP-friendly output. * Fix a flaky false positive in the xen_shinfo_test due to comparing elapsed time across two different clock domains. * Skip the MONITOR/MWAIT test if the host doesn't actually support MWAIT. * Avoid unnecessary use of "sudo" in the NX hugepage test wrapper shell script, to play nice with running in a minimal userspace environment. * Allow skipping the RSEQ test's sanity check that the vCPU was able to complete a reasonable number of KVM_RUNs, as the assert can fail on a completely valid setup. If the test is run on a large-ish system that is otherwise idle, and the test isn't affined to a low-ish number of CPUs, the vCPU task can be repeatedly migrated to CPUs that are in deep sleep states, which results in the vCPU having very little net runtime before the next migration due to high wakeup latencies. * Define _GNU_SOURCE for all selftests to fix a warning that was introduced by a change to kselftest_harness.h late in the 6.9 cycle, and because forcing every test to #define _GNU_SOURCE is painful. * Provide a global pseudo-RNG instance for all tests, so that library code can generate random, but determinstic numbers. * Use the global pRNG to randomly force emulation of select writes from guest code on x86, e.g. to help validate KVM's emulation of locked accesses. * Allocate and initialize x86's GDT, IDT, TSS, segments, and default exception handlers at VM creation, instead of forcing tests to manually trigger the related setup. Documentation: * Fix a goof in the KVM_CREATE_GUEST_MEMFD documentation.
...to receive 3 feature updates and some fixes and cleanups for CXL. Three CXL mailbox passthrough commands are added to support the populating and clearing of vendor debug logs. The second feature is adding support of Device Phyiscal Address (DPA) to Host Physical Address (HPA) translation for CXL events of cxl_dram and cxl_general media. The support allows user space to figure out which CXL region the event occured via trace event. The third feature connects CXL to CPER reporting. If a device is configured for firmware first, CXL event records are not sent directly to the host. Those records are reported through EFI Common Platform Error Records (CPER). Support is added to route the CPER records through the CXL sub-system in order to provide DPA to HPA translation and also event decoding and tracing. This is useful for users to determine which system issues may correspond to specific hardware events. A number of misc cleanups and fixes are also included in this pull request. The following commits have late tags that were submitted after the commits have been pushed to cxl/next branch: 866c0674541f cxl: Fix use of phys_to_target_node() for x86 Reviewed-by: Davidlohr Bueso <[email protected]> d357dd8ad2f1 ("cxl/region: Convert cxl_pmem_region_alloc to scope-based resource management") Reviewed-by: Li Zhijian <[email protected]> Tested-by: Li Zhijian <[email protected]> This pull request has appeared in the linux-next for more than a week and has build success notification from kbuild-robot. --- CXL changes for v6.10 merge window Topics: - Add CXL log related mailbox commands - Add Get Log Capabilities command - Add Get Supported Log Sub-List Commands command - Add Clear Log command - Add series for DPA to HPA translation for CXL events cxl_dram and cxl_general_media - Add support to send CPER records to CXL for more detailed parsing.

Two IMA changes, one EVM change, a use after free bug fix, and a code cleanup to
address "-Wflex-array-member-not-at-end" warnings:
- The existing IMA {ascii, binary}_runtime_measurements lists include a hard
coded SHA1 hash. To address this limitation, define per TPM enabled hash
algorithm {ascii, binary}_runtime_measurements lists.
- Close an IMA integrity init_module syscall measurement gap by defining a new
critical-data record.
- Enable (partial) EVM support on stacked filesystems (overlayfs). Only EVM
portable & immutable file signatures are copied up, since they do not contain
filesystem specific metadata.
thanks,

This is the main pull request for the drm subsystems for 6.10. In drivers the main thing is a new driver for ARM Mali firmware based GPUs, otherwise there are a lot of changes to amdgpu/xe/i915/msm and scattered changes to everything else. In the core a bunch of headers and Kconfig was refactored, along with the addition of a new panic handler which is meant to provide a user friendly message when a panic happens and graphical display is enabled. I did a trial merge and there were only two minor conflicts that I think should be fine for you to handle. I know there are some conflicts on the list from sfr with the devicetree and kbuild trees at least, Regards, Dave. drm-next-2024-05-15: drm for 6.10-rc1 new drivers: - panthor: ARM Mali/Immortalis CSF-based GPU driver core: -

Full disclosure I hit a KASAN OOB read warning in BPF when testing on Meta's production servers (which load a lot of BPF). BPF folks aren't super alarmed by it, and also they are partying at LSFMM so I don't think it's worth waiting for the fix. But you may feel differently... https://pastebin.com/0fzqy3cW In terms of conflicts - there's one trivial one in drivers/of/property.c https://lore.kernel.org/all/[email protected]/ That's the only one at the time of writing. Some more we got from Stephen: drivers/net/wireless/intel/iwlwifi/mvm/Makefile https://lore.kernel.org/all/[email protected]/ net/core/page_pool.c https://lore.kernel.org/all/[email protected]/ The only less trivial one is with MM in include/linux/slab.h https://lore.kernel.org/all/[email protected]/ but I'm not sure this is actually coming to you in this merge window. Networking changes for 6.10. Core & protocols - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS(). This required touch-ups and renaming of a few existing users. - Add Endian-dependent __counted_by_{le,be} annotations. - Make building selftests "quieter" by printing summaries like "CC object.o" rather than full commands with all the arguments. Netfilter --------- - Use GFP_KERNEL to clone elements, to deal better with OOM situations and avoid failures in the .commit step. BPF --- - Add eBPF JIT for ARCv2 CPUs. - Support attaching kprobe BPF programs through kprobe_multi link in a session mode, meaning, a BPF program is attached to both function entry and return, the entry program can decide if the return program gets executed and the entry program can share u64 cookie value with return program. "Session mode" is a common use-case for tetragon and bpftrace. - Add the ability to specify and retrieve BPF cookie for raw tracepoint programs in order to ease migration from classic to raw tracepoints. - Add an internal-only BPF per-CPU instruction for resolving per-CPU memory addresses and implement support in x86, ARM64 and RISC-V JITs. This allows inlining functions which need to access per-CPU state. - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various atomics in bpf_arena which can be JITed as a single x86 instruction. Support BPF arena on ARM64. - Add a new bpf_wq API for deferring events and refactor process-context bpf_timer code to keep common code where possible. - Harden the BPF verifier's and/or/xor value tracking. - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs. - Support bpf_tail_call_static() helper for BPF programs with GCC 13. - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF program to have code sections where preemption is disabled. Driver API - Remove the need to create a config file to run the net forwarding tests so that a naive "make run_tests" can exercise them. - Define a method of writing tests which require an external endpoint to communicate with (to send/receive data towards the test machine). Add a few such tests. - Create a shared code library for writing Python tests. Expose the YAML Netlink library from tools/ to the tests for easy Netlink access. - Move netfilter tests under net/, extend them, separate performance tests from correctness tests, and iron out issues found by running them "on every commit". - Refactor BPF selftests to use common network helpers. - Further work filling in YAML definitions of Netlink messages for: nftables, team driver, bonding interfaces, vlan interfaces, VF info, TC u32 mark, TC police action. - Teach Python YAML Netlink to decode attribute policies. - Extend the definition of the "indexed array" construct in the specs to cover arrays of scalars rather than just nests. - Add hyperlinks between definitions in generated Netlink docs. Drivers ------- - Make sure unsupported flower control flags are rejected by drivers, and make more drivers report errors directly to the application rather than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen). - Ethernet high-speed NICs: - Broadcom (bnxt): - support multiple RSS contexts and steering traffic to them - support XDP metadata - make page pool allocations more NUMA aware - Intel (100G, ice, idpf): - extract datapath code common among Intel drivers into a library - use fewer resources in switchdev by sharing queues with the PF - add PFCP filter support - add Ethernet filter support - use a spinlock instead of HW lock in PTP clock ops - support 5 layer Tx scheduler topology - nVidia/Mellanox: - 800G link modes and 100G SerDes speeds - per-queue IRQ coalescing configuration - Marvell Octeon: - support offloading TC packet mark action - Ethernet NICs consumer, embedded and virtual: - stop lying about skb->truesize in USB Ethernet drivers, it messes up TCP memory calculations - Google cloud vNIC: - support changing ring size via ethtool - support ring reset using the queue control API - VirtIO net: - expose flow hash from RSS to XDP - per-queue statistics - add selftests - Synopsys (stmmac): - support controllers which require an RX clock signal from the MII bus to perform their hardware initialization - TI: - icssg_prueth: support ICSSG-based Ethernet on AM65x SR1.0 devices - icssg_prueth: add SW TX / RX Coalescing based on hrtimers - cpsw: minimal XDP support - Renesas (ravb): - support describing the MDIO bus - Realtek (r8169): - add support for RTL8168M - Microchip Sparx5: - matchall and flower actions mirred and redirect - Ethernet switches: - nVidia/Mellanox: - improve events processing performance - Marvell: - add support for MV88E6250 family internal PHYs - Microchip: - add DCB and DSCP mapping support for KSZ switches - vsc73xx: convert to PHYLINK - Realtek: - rtl8226b/rtl8221b: add C45 instances and SerDes switching - Many driver changes related to PHYLIB and PHYLINK deprecated API cleanup. - Ethernet PHYs: - Add a new driver for Airoha EN8811H 2.5 Gigabit PHY. - micrel: lan8814: add support for PPS out and external timestamp trigger - WiFi: - Disable Wireless Extensions (WEXT) in all Wi-Fi 7 devices drivers.

firewire updates for v6.10 During the development period of v6.8 kernel, it became evident that there was a lack of helper utilities to trace the initial state of bus, while investigating certain PHYs compliant with different versions of IEEE 1394 specification. This series of changes includes the addition of tracepoints events, provided by 'firewire' subsystem. These events enable tracing of how firewire core functions during bus reset and asynchronous communication over IEEE 1394 bus. When implementing the tracepoints events, it was found that the existing serialization and deserialization helpers for several types of asynchronous packets are scattered across both firewire-core and firewire-ohci kernel modules. A set of inline functions is newly added to address it, along with some KUnit tests, serving as the foundation for the tracepoints events. This renders the dispersed code obsolete. The remaining changes constitute the final steps in phasing out the usage of deprecated PCI MSI APIs, in continuation from the previous version.
Modules changes for v6.10-rc1 Finally something fun. Mike Rapoport does some cleanup to allow us to take out module_alloc() out of modules into a new paint shedded execmem_alloc() and execmem_free() so to make emphasis these helpers are actually used outside of modules. It starts with a no-functional changes API rename / placeholders to then allow architectures to define their requirements into a new shiny struct execmem_info with ranges, and requirements for those ranges. Archs now can intitialize this execmem_info as the last part of mm_core_init() if they have to diverge from the norm. Each range is a known type clearly articulated and spelled out in enum execmem_type. Although a lot of this is major cleanup and prep work for future enhancements an immediate clear gain is we get to enable KPROBES without MODULES now. That is ultimately what motiviated to pick this work up again, now with smaller goal as concrete stepping stone. This has been sitting on linux-next for a little less than a month, a few issues were found already and fixed, in particular an odd mips boot issue. Arch folks reviewed the code too. This is ready for wider exposure and testing.
This was a quiet release cycle for the GPIO tree and so the main pull-request is relatively small. We have one new driver, some minor improvements to the GPIO core code and across several drivers, some DT and documentation updates but in general nothing stands out or is controversial. All changes have spent time in next with no reported issues (or ones that were quickly fixed). Details are in the signed tag. Please consider pulling. Best Regards, Bartosz Golaszewski gpio updates for v6.10-rc1 GPIO core: - remove more unused legacy interfaces (after converting the last remaining users to better alternatives) - update kerneldocs - improve error handling and log messages in GPIO ACPI code - remove dead code (always true checks) from GPIOLIB New drivers: - add a driver for Intel Granite Rapids-D vGPIO Driver improvements: - use -ENOTSUPP consistently in gpio-regmap and gpio-pcie-idio-24 - provide an ID table for gpio-cros-ec to avoid a driver name fallback check - add support for gpio-ranges for GPIO drivers supporting multiple GPIO banks - switch to using dynamic GPIO base in gpio-brcmstb - fix irq handling in gpio-npcm-sgpio - switch to memory mapped IO accessors in gpio-sch DT bindings: - add support for gpio-ranges to gpio-brcmstb - add support for a new model and the gpio-line-names property to gpio-mpfs Documentation: - replace leading tabs with spaces in code blocks - fix typos

This set includes some small fixes, and some big internal changes: - Fix a long standing race between the unlock callback for the last lkb struct, and removing the rsb that became unused after the final unlock. This could lead different nodes to inconsistent info about the rsb master node. - Remove unnecessary refcounting on callback structs, returning to the way things were done in the past. - Do message processing in softirq context. This allows dlm messages to be cleared more quickly and efficiently, reducing long lists of incomplete requests. A future change to run callbacks directly from this context will make this more effective. - The softirq message processing involved a number of patches changing mutexes to spinlocks and rwlocks, and a fair amount of code re-org in preparation. - Use an rhashtable for rsb structs, rather than our old internal hash table implementation. This also required some re-org of lists and locks preparation for the change. - Drop the dlm_scand kthread, and use timers to clear unused rsb structs. Scanning all rsb's periodically was a lot of wasted work. - Fix recent regression in logic for copying LVB data in user space lock requests. Thanks, Dave
please pull a couple of x86/sev cleanups for v6.10-rc1. Diffstat is a bit largish but this is due to code movement to avoid forward declarations. Thx. --- - Small cleanups and improvements
about some 64-bit divisions, but the divisor was really just a 32-bit value being stored as 'unsigned long'. Fixing the types fixes the warning. -- Improve data types to fix Coccinelle division warnings

pm-6.10-rc1 Linux 6.9-rc7 to receive power management updates for 6.10-rc1. These are mostly cpufreq updates, including a significant intel-pstate driver update and several amd-pstate improvements plus some updates of ARM cpufreq drivers, general fixes and cleanups. Also included are changes related to system sleep, power capping updates adding support for a new platform and a new hardware feature (among other things), a Samsung exynos-asv driver update allowing it to change its Energy Model after adjusting voltage, minor cpuidle and devfreq updates and a small documentation cleanup. Specifics: - Rework the handling of disabled turbo in the intel_pstate driver and make it update the maximum CPU frequency consistently regardless of the reason on top of a number of cleanups (Rafael Wysocki). - Add missing checks for NULL .exit() cpufreq driver callback to the cpufreq core (Viresh Kumar). - Prevent pulicy->max from going above the frequency QoS maximum value when cpufreq_frequency_table_verify() is used (Xuewen Yan). - Prevent a negative CPU number or frequency value from being printed if they are really large (Joshua Yeong). - Update MAINTAINERS entry for amd-pstate to add two new submaintainers and a designated reviewer (Huang Rui). - Clean up the amd-pstate driver and update its documentation (Gautham Shenoy). - Fix the highest frequency issue in the amd-pstate driver which limits performance (Perry Yuan). - Enable CPPC v2 for certain processors in the family 17H, as requested by TR40 processor users who expect improved performance and lower system temperature (Perry Yuan). - Change latency and delay values to be read from platform firmware firstly for more accurate timing (Perry Yuan). - A new quirk is introduced for supporting amd-pstate on legacy processors which either lack CPPC capability, or only only have CPPC v2 capability (Perry Yuan). - Sun50i cpufreq: Add support for opp_supported_hw, H616 platform and general cleanups (Andre Przywara, Martin Botka, Brandon Cheo Fusi, Dan Carpenter, Viresh Kumar). - CPPC cpufreq: Fix possible null pointer dereference (Aleksandr Mishin). - Eliminate uses of of_node_put() from cpufreq (Javier Carrasco, Shivani Gupta). - brcmstb-avs: ISO C90 forbids mixed declarations (Portia Stephens). - mediatek cpufreq: Add support for MT7988A (Sam Shih). - cpufreq-qcom-hw: Add SM4450 compatibles in DT bindings (Tengfei Fan). - Fix struct cpudata::epp_cached kernel-doc in the intel_pstate cpufreq driver (Jeff Johnson). - Fix kerneldoc description of ladder_do_selection() (Jeff Johnson). - Convert the cpuidle kirkwood driver to platform remove callback returning void (Yangtao Li). - Replace deprecated strncpy() with strscpy() in the hibernation core code (Justin Stitt). - Use %ps to simplify debug output in the core system-wide suspend and resume code (Len Brown). - Remove unnecessary else from device_init_wakeup() and make device_wakeup_disable() return void (Dhruva Gole). - Enable PMU support in the Intel TPMI RAPL driver (Zhang Rui). - Add support for ArrowLake-H platform to the Intel RAPL driver (Zhang Rui). - Avoid explicit cpumask allocation on stack in DTPM (Dawei Li). - Make the Samsung exynos-asv driver update the Energy Model after adjusting voltage on top of some preliminary changes of the OPP and Enery Model generic code (Lukasz Luba). - Remove a reference to a function that has been dropped from the power management documentation (Bjorn Helgaas). - Convert the platfrom remove callback to .remove_new for the exyno-nocp, exynos-ppmu, mtk-cci-devfreq, sun8i-a33-mbus, and rk3399_dmc devfreq drivers (Uwe Kleine-K=C3=B6nig). - Use DEFINE_SIMPLE_PM_OPS for exyno-bus.c driver (Anand Moon).

thermal-6.10-rc1 Merge branch 'thermal-intel' thermal/debugfs: Prevent use-after-free from occurring after cdev removal to receive thermal control updates for 6.10-rc1. The most significant part of this is a rework of thermal governors, including a redesign of the thermal governor interface and changes to make some of them take trip point hysteresis into account properly, as well as some related cleanups of the thermal governors and thermal core. The above is based on preliminary changes refactoring thermal data structures and moving the definitions of some of them into the thermal core which also ensure that trip point crossing notifications will be sent to user space via netlink and recorded in the debug statistics in temperature order. In addition, netlink bind/unbind notifications are added to the thermal core and the Intel HFI driver is modified to use them to avoid sending netlink messages until there are subscribers. Apart from that, multiple thermal drivers are updated which includes new hardware support (MediaTek MT8188 and MT8186, Amlogic A1 thermal sensor, Loongson-2K2000, Lmh QCM2290), fixes, cleanups and documentation updates, and the recently added thermal debug code is fixed and cleaned up. Specifics: - Redesign the thermal governor interface to allow the governors to work in a more straightforward way (Rafael Wysocki). - Make thermal governors take the current trip point thresholds into account in their computations which allows trip hysteresis to be observed more accurately (Rafael Wysocki). - Make the thermal core manage passive polling for thermal zones and remove passive polling management from thermal governors (Rafael Wysocki). - Refactor trip point representation and move the definition of thermal governor and thermal zone device structures to the thermal core (Rafael Wysocki). - Sort trip point crossing notifications and debug recording of trip point crossing events by temperature (Rafael Wysocki). - Improve the handling of cooling device states and thermal mitigation episodes in progress in the thermal debug code (Rafael Wysocki). - Avoid excessive updates of trip point statistics and clean up the printing of thermal mitigation episode information (Rafael Wysocki). - Clean up thermal governors and thermal core (Rafael Wysocki). - Allow thermal drivers to register notifiers that will be invoked on netlink events like BIND and UNBIND, so that they can adjust their activity depending on whether or not there are any subscribers of netlink messages coming from them, and make the Intel HFI driver use this mechanism (Stanislaw Gruszka). - Adjust the update delay and capabilities-per-event values in the Intel HFI thermal driver to prevent it from missing events and allow it to process more data in one go (Ricardo Neri). - Add missing MODULE_DESCRIPTION() to multiple files in the int340x_thermal and intel_soc_dts_iosf drivers (Srinivas Pandruvada). - Replace deprecated strncpy() with strscpy() in the int340x_thermal driver (Justin Stitt). - Add QCM2290 compatible DT bindings for Lmh and fix a NULL pointer dereference in the lmh driver when the SCM is not present (Konrad Dybcio). - Use the strreplace() function instead of doing it manually in the Armada driver (Rasmus Villemoes). - Convert st,stih407-thermal to DT schema and fix up missing properties (Raphael Gallais-Pou). - Add suspend/resume by restoring the context of the tsens sensor (Priyansh Jain). - Support A1 SoC family Thermal Sensor controller and add the DT bindings (Dmitry Rokosov). - Improve the temperature approximation calculation and consolidate the Tj constant into a shared area of the structure instead of duplicating it on the Rcar Gen3 (Niklas S=C3=B6derlund). - Fix the Mediatek LVTS sensor coefficient for the MT8192 in order to supp= ort it correctly (Hsin-Te Yuan). - Fix a NULL pointer dereference in the tsens driver when the function compute_intercept_slope() is called with a NULL parameter (Aleksandr Mishin). - Remove some unused fields in struct qpnp_tm_chip and k3_bandgap (Christophe Jaillet). - Fix up calibration efuse data decoding, consolidate the code by checking boundaries and refactor some part of the LVTS Mediatek driver. After setting the scene, add MT8186 and MT8188 along with the DT bindings (Nicolas Pitre). - Add Loongson-2K2000 support after some minor code adjustments and providing the DT bindings definition (Binbin Zhou).

does.
Thx.

- Switch the in-place instruction patching which lead to at least one weird bug
with 32-bit guests, seeing stale instruction bytes, to one working on
a buffer, like the rest of the alternatives code does
- Add a long overdue check to the X86_FEATURE flag modifying functions to warn
when former get changed in a non-compatible way after alternatives have been
patched because those changes will be already wrong

Hi,
this update brings a few minor performance improvements, otherwise
there's a lot of refactoring, cleanups and other sort of not user
visible changes.
Performance improvements
- inline b-tree locking functions, improvement in metadata-heavy changes
- relax locking on a range that's being reflinked, allows read operations to
run in parallel
- speed up NOCOW write checks (throughput +9% on a sample test)
- extent locking ranges have been reduced in several places, namely
around delayed ref processing
Core
- more page to folio conversions
- relocation
- send
- compression
- inline extent handling
- super block write and wait
- extent_map structure optimizations
- reduced structure size
- code simplifications
- add shrinker for allocated objects, the numbers can go high and could
exhaust memory on smaller systems (reported) as they may not get an
opportunity to be freed fast enough
- extent locking optimizations
- reduce locking ranges where it does not seem to be necessary and
are safe due to other means of synchronization
- potential improvements due to lower contention, allocation/freeing
and state management operations of extent state tracking structures
- delayed ref cleanups and simplifications
- updated trace points
- improved error handling, warnings and assertions
- cleanups and refactoring, unification of error handling paths

but the most interesting parts are probably the mm changes from Ryan which optimise the creation of the linear mapping at boot and (separately) implement write-protect support for userfaultfd. Outside of our usual directories, the Kbuild-related changes under scripts/ have been acked by Masahiro whilst the drivers/acpi/ parts have been acked by Rafael and the addition of cpumask_any_and_but() has been acked by Yury. I've also picked up some CPU errata workarounds since tagging this, so I'll aim to send those next week. Cheers, Will --->8 arm64 updates for 6.10 ACPI: * Support for the Firmware ACPI Control Structure (FACS) signature feature which is used to reboot out of hibernation on some systems.

Memory management: * Optimisation of our early page-table manipulation for creation of the linear mapping. * Support for userfaultfd write protection, which brings along some nice cleanups to our handling of invalid but present ptes. * Extend our use of range TLBI invalidation at EL1. Perf and PMUs: * Ensure that the 'pmu->parent' pointer is correctly initialised by PMU drivers. * Avoid allocating 'cpumask_t' types on the stack in some PMU drivers. * Fix parsing of the CPU PMU "version" field in assembly code, as it doesn't follow the usual architectural rules. * Add best-effort unwinding support for USER_STACKTRACE * Minor driver fixes and cleanups. Selftests: * Minor cleanups to the arm64 selftests (missing NULL check, unused variable). Miscellaneous * Add a command-line alias for disabling 32-bit application support. * Add part number for Neoverse-V2 CPUs. * Minor fixes and cleanups.

Updates for the interrupt subsystem:
- Core code:
- Interrupt storm detection for the lockup watchdog:
Lockups which are caused by interrupt storms are not easy to debug
because there is no information about the events which make the lockup
detector trigger.
To make this more user friendly, provide an extenstion to interrupt
statistics which allows to take snapshots and an interface to retrieve
the delta to the snapshot. Use this new mechanism in the watchdog code
to do a two stage lockup analysis by taking the snapshot and printing
the deltas for the topmost active interrupts on the second trigger.
Note: This contains both the interrupt and the watchdog changes as
the latter depend on the former obviously.
- Avoid summation loops in the /proc/interrupts output and use the global
counter when possible
- Skip suspended interrupts on CPU hotplug operations to ensure that they
are not delivered before the system resumes the device drivers when
coming out of suspend.
- On CPU hot-unplug interrupts which are affine to the outgoing CPU are
migrated to a different CPU in the affinity mask. This can fail when
the CPUs have no vectors left. Instead of giving up try to migrate it
to any online CPU and thereby breaking the affinity setting in order to
prevent a stale device interrupt which targets an offline CPU
- The usual small cleanups
- Driver code:
- Support for the RISCV AIA MSI controller
- Make the interrupt allocation for the Loongson PCH controller more
flexible to prevent vector exhaustion
- The usual set of cleanups and fixes all over the place

X86 interrupt handling update:
Support for posted interrupts on bare metal
Posted interrupts is a virtualization feature which allows to inject
interrupts directly into a guest without host interaction. The VT-d
interrupt remapping hardware sets the bit which corresponds to the
interrupt vector in a vector bitmap which is either used to inject the
interrupt directly into the guest via a virtualized APIC or in case
that the guest is scheduled out provides a host side notification
interrupt which informs the host that an interrupt has been marked
pending in the bitmap.
This can be utilized on bare metal for scenarios where multiple
devices, e.g. NVME storage, raise interrupts with a high frequency. In
the default mode these interrupts are handles independently and
therefore require a full roundtrip of interrupt entry/exit.
Utilizing posted interrupts this roundtrip overhead can be avoided by
coalescing these interrupt entries to a single entry for the posted
interrupt notification. The notification interrupt then demultiplexes
the pending bits in a memory based bitmap and invokes the corresponding
device specific handlers.
Depending on the usage scenario and device utilization throughput
improvements between 10% and 130% have been measured.
As this is only relevant for high end servers with multiple device
queues per CPU attached and counterproductive for situations where
interrupts are arriving at distinct times, the functionality is opt-in
via a kernel command line parameter.
Thanks,
tglx
please pull the latest timers/core branch from:
-05-12
people/daniel.lezcano/linux into timers/core
Timers and timekeeping updates:
- Core code:
- Make timekeeping and VDSO time readouts resilent against math overflow:
In guest context the kernel is prone to math overflow when the host
defers the timer interrupt due to overload, malfunction or malice.
This can be mitigated by checking the clocksource delta for the
maximum deferrement which is readily available. If that value is
exceeded then the code uses a slowpath function which can handle the
multiplication overflow.
This functionality is enabled unconditionally in the kernel, but made
conditional in the VDSO code. The latter is conditional because it
allows architectures to optimize the check so it is not causing
performance regressions.
On X86 this is achieved by reworking the existing check for negative
TSC deltas as a negative delta obviously exceeds the maximum
deferrement when it is evaluated as an unsigned value. That avoids two
conditionals in the hotpath and allows to hide both the negative delta
and the large delta handling in the same slow path.
- Add an initial minimal ktime_t abstraction for Rust
- The usual boring cleanups and enhancements
- Drivers:
- Boring updates to device trees and trivial enhancements in various
drivers.
Thanks,
tglx
please pull the latest x86/timers branch from: 05-13 st MSRs A single update for the TSC synchronixation sanity checks: The sad state of TSC being notoriously non-sychronized for several decades caused the kernel to grow quite rigorous sanity checks to detect whether the TSC is valid to be used for timekeeping. The TSC ADJUST MSR provides the offset between the initial TSC value after hardware reset and later modifications. This allows to detect cases where firmware tampers with the TSC and also allows to correct the firmware induced damage by resetting the offset in a controlled way. The universal correct rule is that the TSC ADJUST value has to be consistent within all CPUs of a socket. The kernel further assumes that the TSC offset should be consistent between sockets. That's not really correct as systems with a huge number of sockets are not architecurally guaranteed to reset the per socket TSC base synchronously. In case that the per socket offset is not consistent the kernel resets it to the offset of the boot CPU and then does a synchronization check which corrects for the inter socket delays. That works most of the time, but it is suboptimal as the firmware has eventually better information about the per socket offset and on sane systems that offset should just work in the validation checks. Thanks, tglx
please pull a single RAS update for v6.10-rc1. Thx. --- - Change the fixed-size buffer for MCE records to a dynamically sized one based on the number of CPUs present in the system
m68k updates for v6.10 - Fix invalid context sleep and reboot hang on Mac, - Fix spinlock race in kernel thread creation, - Miscellaneous fixes and improvements, - Defconfig updates. Thanks for pulling!
regmap: Updates for v6.10 Other than a few cleanups the changes here are all in the KUnit tests, Richard Fitzgerald sent some bug fixes during the v6.9 cycle and while adding test coverage for the issues fixed did some fairly substantial improvements, both cleaning up the framework and building out the coverage.
spi: Updates for v6.10 The diffstat for this release is dominated by the new Airoha driver, mainly as a result of this being a generally quite quiet release. There were a couple of cleanups in the core but nothing substantial, the updates here are almost all driver specific ones. - Support for multi-word mode in the OMAP2 McSPI driver. - Overhaul of the PXA2xx driver, mostly API updates. - A number of DT binding conversions. - Support for Airoha NAND controllers, Cirrus Logic CS35L56, Mobileye EYEQ5 and Renesas R8A779H0.
regulator: Updates for v6.10 There's one API update here, a new API factoring out a common pattern for reference voltage supplies. These are supplies uses as a reference by analogue circuits where the consumer requests and enables the supply, reads the voltage to calibrate the user and then never touches it again. This is factored out into a single operation which just returns the voltage and uses devm_ to manage the request and enable portion. Otherwise this has been a very quiet release, we've got some new device support, some small fixes, housekeeping and cleanup work but nothing substantial. There's also some non-regulator changes in here, a number of users for the new reference voltage API were merged along with it and some MFD changes were pulled in as dependencies for new driver work. Highlights: - Add a new API for single operation handling of reference voltages. - Support for Allwinner AXP717 and D1, and NXP PCA9561A.
please pull a boring set of EDAC updates for 6.10. Thx. --- - Have skx_edac decode error addresses belonging to SGX properly - Remove a bunch of unused struct members - Other cleanups

x86/cpu changes for v6.10: - Rework the x86 CPU vendor/family/model code: introduce the 'VFM' value that is an 8+8+8 bit concatenation of the vendor/family/model value, and add macros that work on VFM values. This simplifies the addition of new Intel models & families, and simplifies existing enumeration & quirk code. - Add support for the AMD 0x80000026 leaf, to better parse topology information. - Optimize the NUMA allocation layout of more per-CPU data structures - Improve the workaround for AMD erratum 1386 - Clear TME from /proc/cpuinfo as well, when disabled by the firmware - Improve x86 self-tests - Extend the mce_record tracepoint with the ::ppin and ::microcode fields - Implement recovery for MCE errors in TDX/SEAM non-root mode - Misc cleanups and fixes Thanks, Ingo
Use uniform "Oops: " prefix for die() messages. Thanks, Ingo
x86/build changes for v6.10: - Use -fpic to build the kexec 'purgatory' (self-contained code that runs between two kernels) - Clean up vmlinux.lds.S generation - Simplify the X86_EXTENDED_PLATFORM section of the x86 Kconfig - Misc cleanups & fixes Thanks, Ingo
x86/boot changes for v6.10: - Move the kernel cmdline setup earlier in the boot process (again), to address a split_lock_detect= boot parameter bug. - Ignore relocations in .notes sections - Simplify boot stack setup - Re-introduce a bootloader quirk wrt. CR4 handling - Miscellaneous cleanups & fixes Thanks, Ingo
x86/asm changes for v6.10: - Clean up & fix asm() operand modifiers & constraints - Misc cleanups Thanks, Ingo
Scheduler changes for v6.10: - Add cpufreq pressure feedback for the scheduler - Rework misfit load-balancing wrt. affinity restrictions - Clean up and simplify the code around ::overutilized and ::overload access. - Simplify sched_balance_newidle() - Bump SCHEDSTAT_VERSION to 16 due to a cleanup of CPU_MAX_IDLE_TYPES handling that changed the output. - Rework & clean up <asm/vtime.h> interactions wrt. arch_vtime_task_switch() - Reorganize, clean up and unify most of the higher level scheduler balancing function names around the sched_balance_*() prefix. - Simplify the balancing flag code (sched_balance_running) - Miscellaneous cleanups & fixes Thanks, Ingo
Perf events changes for v6.10: - Combine perf and BPF for fast evalution of HW breakpoint conditions. - Add LBR capture support outside of hardware events - Trigger IO signals for watermark_wakeup - Add RAPL support for Intel Arrow Lake and Lunar Lake - Optimize frequency-throttling - Miscellaneous cleanups & fixes. Thanks, Ingo
Could you consider this pull request for 6.10-rc1? In this cycle, LZ4 global buffer count is now configurable instead of the previous per-CPU buffers, which is useful for bare metals with hundreds of CPUs. A reserved buffer pool for LZ4 decompression can also be enabled to minimize the tail allocation latencies under the low memory scenarios with heavy memory pressure. In addition, Zstandard algorithm is now supported as an alternative since it has been requested by users for a while. There are some random cleanups as usual. All commits have been in -next and no potential merge conflict is observed. Thanks, Gao Xiang Changes since last update: - Make LZ4 global buffers configurable instead of per-CPU buffers; - Add a reserved buffer pool for LZ4 decompression for lower latencies; - Support Zstandard compression algorithm as an alternative; - Derive fsid from on-disk UUID for .statfs() if possible; - Minor cleanups.
Locking changes for v6.10: - Over a dozen code generation micro-optimizations for the atomic and spinlock code. - Add more __ro_after_init attributes - Robustify the lockdevent_*() macros Thanks, Ingo
