ACPI: processor: Move arch_init_invariance_cppc() call later
arch_init_invariance_cppc() is called at the end of acpi_cppc_processor_probe() in order to configure frequency invariance based upon the values from _CPC. This however doesn't work on AMD CPPC shared memory designs that have AMD preferred cores enabled because _CPC needs to be analyzed from all cores to judge if preferred cores are enabled. This issue manifests to users as a warning since commit |

sugov_update_shared() locks a raw_spinlock while cpc_write() locks a
spinlock.
To have a correct wait-type order, update rmw_lock to a raw spinlock and
ensure that interrupts will be disabled on the CPU holding it.

Pull power management updates from Rafael Wysocki:
"By the number of new lines of code, the most visible change here is
the addition of hybrid CPU capacity scaling support to the
intel_pstate driver. Next are the amd-pstate driver changes related to
the calculation of the AMD boost numerator and preferred core
detection.
As far as new hardware support is concerned, the intel_idle driver
will now handle Granite Rapids Xeon processors natively, the
intel_rapl power capping driver will recognize family 1Ah of AMD
processors and Intel ArrowLake-U chipos, and intel_pstate will handle
Granite Rapids and Sierra Forest chips in the out-of-band (OOB) mode.
Apart from the above, there is a usual collection of assorted fixes
and code cleanups in many places and there are tooling updates.

x86/amd: Detect preferred cores in amd_get_boost_ratio_numerator()
AMD systems that support preferred cores will use "166" as their numerator for max frequency calculations instead of "255". Add a function for detecting preferred cores by looking at the highest perf value on all cores. If preferred cores are enabled return 166 and if disabled the value in the highest perf register. As the function will be called multiple times, cache the values for the boost numerator and if preferred cores will be enabled in global variables. Reviewed-by: Gautham R.

x86/amd: Move amd_get_highest_perf() out of amd-pstate
amd_pstate_get_highest_perf() is a helper used to get the highest perf value on AMD systems. It's used in amd-pstate as part of preferred core handling, but applicable for acpi-cpufreq as well. Move it out to cppc handling code as amd_get_highest_perf(). Reviewed-by: Perry Yuan <perry.yuan@amd.com> Reviewed-by: Gautham R.

x86/amd: Rename amd_get_highest_perf() to amd_get_boost_ratio_numerator()
The function name is ambiguous because it returns an intermediate value for calculating maximum frequency rather than the CPPC 'Highest Perf' register. Rename the function to clarify its use and allow the function to return errors. Adjust the consumer in acpi-cpufreq to catch errors. Reviewed-by: Gautham R.

ACPI: CPPC: Fix MASK_VAL() usage
MASK_VAL() was added as a way to handle bit_offset and bit_width for
registers located in system memory address space. However, while suited
for reading, it does not work for writing and result in corrupted
registers when writing values with bit_offset > 0. Moreover, when a
register is collocated with another one at the same address but with a
different mask, the current code results in the other registers being
overwritten with 0s. The write procedure for SYSTEM_MEMORY registers
should actually read the value, mask it, update it and write it with the
updated value. Moreover, since registers can be located in the same
word, we must take care of locking the access before doing it. We should
potentially use a global lock since we don't know in if register
addresses aren't shared with another _CPC package but better not
encourage vendors to do so. Assume that registers can use the same word
inside a _CPC package and thus, use a per _CPC package lock.

Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

Yu has a fix which I'll send along later via the hotfixes branch. - In the series "mm: Avoid possible overflows in dirty throttling" Jan Kara addresses a couple of issues in the writeback throttling code. These fixes are also targetted at -stable kernels. - Ryusuke Konishi's series "nilfs2: fix potential issues related to reserved inodes" does that. This should actually be in the mm-nonmm-stable tree, along with the many other nilfs2 patches. My bad. - More folio conversions from Kefeng Wang in the series "mm: convert to folio_alloc_mpol()" - Kemeng Shi has sent some cleanups to the writeback code in the series "Add helper functions to remove repeated code and improve readability of cgroup writeback" - Kairui Song has made the swap code a little smaller and a little faster in the series "mm/swap: clean up and optimize swap cache index". - In the series "mm/memory: cleanly support zeropage in vm_insert_page*(), vm_map_pages*() and vmf_insert_mixed()" David Hildenbrand has reworked the rather sketchy handling of the use of the zeropage in MAP_SHARED mappings. I don't see any runtime effects here - more a cleanup/understandability/maintainablity thing. - Dev Jain has improved selftests/mm/va_high_addr_switch.c's handling of higher addresses, for aarch64. The (poorly named) series is "Restructure va_high_addr_switch". - The core TLB handling code gets some cleanups and possible slight optimizations in Bang Li's series "Add update_mmu_tlb_range() to simplify code". - Jane Chu has improved the handling of our fake-an-unrecoverable-memory-error testing feature MADV_HWPOISON in the series "Enhance soft hwpoison handling and injection". - Jeff Johnson has sent a billion patches everywhere to add MODULE_DESCRIPTION() to everything. Some landed in this pull. - In the series "mm: cleanup MIGRATE_SYNC_NO_COPY mode", Kefeng Wang has simplified migration's use of hardware-offload memory copying. - Yosry Ahmed performs more folio API conversions in his series "mm: zswap: trivial folio conversions". - In the series "large folios swap-in: handle refault cases first", Chuanhua Han inches us forward in the handling of large pages in the swap code. This is a cleanup and optimization, working toward the end objective of full support of large folio swapin/out. - In the series "mm,swap: cleanup VMA based swap readahead window calculation", Huang Ying has contributed some cleanups and a possible fixlet to his VMA based swap readahead code. - In the series "add mTHP support for anonymous shmem" Baolin Wang has taught anonymous shmem mappings to use multisize THP. By default this is a no-op - users must opt in vis sysfs controls. Dramatic improvements in pagefault latency are realized. - David Hildenbrand has some cleanups to our remaining use of page_mapcount() in the series "fs/proc: move page_mapcount() to fs/proc/internal.h". - David also has some highmem accounting cleanups in the series "mm/highmem: don't track highmem pages manually". - Build-time fixes and cleanups from John Hubbard in the series "cleanups, fixes, and progress towards avoiding "make headers"". - Cleanups and consolidation of the core pagemap handling from Barry Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers and utilize them". - Lance Yang's series "Reclaim lazyfree THP without splitting" has reduced the latency of the reclaim of pmd-mapped THPs under fairly common circumstances. A 10x speedup is seen in a microbenchmark. It does this by punting to aother CPU but I guess that's a win unless all CPUs are pegged. - hugetlb_cgroup cleanups from Xiu Jianfeng in the series "mm/hugetlb_cgroup: rework on cftypes". - Miaohe Lin's series "Some cleanups for memory-failure" does just that thing. - Is anyone reading this stuff? If so, email me! - Someone other than SeongJae has developed a DAMON feature in Honggyu Kim's series "DAMON based tiered memory management for CXL memory". This adds DAMON features which may be used to help determine the efficiency of our placement of CXL/PCIe attached DRAM. - DAMON user API centralization and simplificatio work in SeongJae Park's series "mm/damon: introduce DAMON parameters online commit function". - In the series "mm: page_type, zsmalloc and page_mapcount_reset()" David Hildenbrand does some maintenance work on zsmalloc - partially modernizing its use of pageframe fields. - Kefeng Wang provides more folio conversions in the series "mm: remove page_maybe_dma_pinned() and page_mkclean()". - More cleanup from David Hildenbrand, this time in the series "mm/memory_hotplug: use PageOffline() instead of PageReserved() for !ZONE_DEVICE". It "enlightens memory hotplug more about PageOffline() pages" and permits the removal of some virtio-mem hacks. - Barry Song's series "mm: clarify folio_add_new_anon_rmap() and __folio_add_anon_rmap()" is a cleanup to the anon folio handling in preparation for mTHP (multisize THP) swapin. - Kefeng Wang's series "mm: improve clear and copy user folio" implements more folio conversions, this time in the area of large folio userspace copying. - The series "Docs/mm/damon/maintaier-profile: document a mailing tool and community meetup series" tells people how to get better involved with other DAMON developers. From SeongJae Park. - A large series ("kmsan: Enable on s390") from Ilya Leoshkevich does that. - David Hildenbrand sends along more cleanups, this time against the migration code. The series is "mm/migrate: move NUMA hinting fault folio isolation + checks under PTL". - Jan Kara has found quite a lot of strangenesses and minor errors in the readahead code. He addresses this in the series "mm: Fix various readahead quirks". - SeongJae Park's series "selftests/damon: test DAMOS tried regions and {min,max}_nr_regions" adds features and addresses errors in DAMON's self testing code. - Gavin Shan has found a userspace-triggerable WARN in the pagecache code. The series "mm/filemap: Limit page cache size to that supported by xarray" addresses this. The series is marked cc:stable. - Chengming Zhou's series "mm/ksm: cmp_and_merge_page() optimizations and cleanup" cleans up and slightly optimizes KSM. - Roman Gushchin has separated the memcg-v1 and memcg-v2 code - lots of code motion. The series (which also makes the memcg-v1 code Kconfigurable) are "mm: memcg: separate legacy cgroup v1 code and put under config option" and "mm: memcg: put cgroup v1-specific memcg data under CONFIG_MEMCG_V1" - Dan Schatzberg's series "Add swappiness argument to memory.reclaim" adds an additional feature to this cgroup-v2 control file. - The series "Userspace controls soft-offline pages" from Jiaqi Yan permits userspace to stop the kernel's automatic treatment of excessive correctable memory errors. In order to permit userspace to monitor and handle this situation. - Kefeng Wang's series "mm: migrate: support poison recover from migrate folio" teaches the kernel to appropriately handle migration from poisoned source folios rather than simply panicing. - SeongJae Park's series "Docs/damon: minor fixups and improvements" does those things. - In the series "mm/zsmalloc: change back to per-size_class lock" Chengming Zhou improves zsmalloc's scalability and memory utilization. - Vivek Kasireddy's series "mm/gup: Introduce memfd_pin_folios() for pinning memfd folios" makes the GUP code use FOLL_PIN rather than bare refcount increments. So these paes can first be moved aside if they reside in the movable zone or a CMA block. - Andrii Nakryiko has added a binary ioctl()-based API to /proc/pid/maps for much faster reading of vma information. The series is "query VMAs from /proc/<pid>/maps". - In the series "mm: introduce per-order mTHP split counters" Lance Yang improves the kernel's presentation of developer information related to multisize THP splitting. - Michael Ellerman has developed the series "Reimplement huge pages without hugepd on powerpc (8xx, e500, book3s/64)". This permits userspace to use all available huge page sizes. - In the series "revert unconditional slab and page allocator fault injection calls" Vlastimil Babka removes a performance-affecting and not very useful feature from slab fault injection. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCZp2C+QAKCRDdBJ7gKXxA joTkAQDvjqOoFStqk4GU3OXMYB7WCU/ZQMFG0iuu1EEwTVDZ4QEA8CnG7seek1R3 xEoo+vw0sWWeLV3qzsxnCA1BJ8cTJA8= =z0Lf -----END PGP SIGNATURE----- Merge tag 'mm-stable-2024-07-21-14-50' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - In the series "mm: Avoid possible overflows in dirty throttling" Jan Kara addresses a couple of issues in the writeback throttling code.

Dramatic improvements in pagefault latency are realized. - David Hildenbrand has some cleanups to our remaining use of page_mapcount() in the series "fs/proc: move page_mapcount() to fs/proc/internal.h". - David also has some highmem accounting cleanups in the series "mm/highmem: don't track highmem pages manually". - Build-time fixes and cleanups from John Hubbard in the series "cleanups, fixes, and progress towards avoiding "make headers"". - Cleanups and consolidation of the core pagemap handling from Barry Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers and utilize them". - Lance Yang's series "Reclaim lazyfree THP without splitting" has reduced the latency of the reclaim of pmd-mapped THPs under fairly common circumstances. A 10x speedup is seen in a microbenchmark. It does this by punting to aother CPU but I guess that's a win unless all CPUs are pegged. - hugetlb_cgroup cleanups from Xiu Jianfeng in the series "mm/hugetlb_cgroup: rework on cftypes". - Miaohe Lin's series "Some cleanups for memory-failure" does just that thing. - Someone other than SeongJae has developed a DAMON feature in Honggyu Kim's series "DAMON based tiered memory management for CXL memory". This adds DAMON features which may be used to help determine the efficiency of our placement of CXL/PCIe attached DRAM. - DAMON user API centralization and simplificatio work in SeongJae Park's series "mm/damon: introduce DAMON parameters online commit function". - In the series "mm: page_type, zsmalloc and page_mapcount_reset()" David Hildenbrand does some maintenance work on zsmalloc - partially modernizing its use of pageframe fields. - Kefeng Wang provides more folio conversions in the series "mm: remove page_maybe_dma_pinned() and page_mkclean()". - More cleanup from David Hildenbrand, this time in the series "mm/memory_hotplug: use PageOffline() instead of PageReserved() for !ZONE_DEVICE". It "enlightens memory hotplug more about PageOffline() pages" and permits the removal of some virtio-mem hacks. - Barry Song's series "mm: clarify folio_add_new_anon_rmap() and __folio_add_anon_rmap()" is a cleanup to the anon folio handling in preparation for mTHP (multisize THP) swapin. - Kefeng Wang's series "mm: improve clear and copy user folio" implements more folio conversions, this time in the area of large folio userspace copying. - The series "Docs/mm/damon/maintaier-profile: document a mailing tool and community meetup series" tells people how to get better involved with other DAMON developers. From SeongJae Park. - A large series ("kmsan: Enable on s390") from Ilya Leoshkevich does that. - David Hildenbrand sends along more cleanups, this time against the migration code. The series is "mm/migrate: move NUMA hinting fault folio isolation + checks under PTL". - Jan Kara has found quite a lot of strangenesses and minor errors in the readahead code. He addresses this in the series "mm: Fix various readahead quirks". - SeongJae Park's series "selftests/damon: test DAMOS tried regions and {min,max}_nr_regions" adds features and addresses errors in DAMON's self testing code. - Gavin Shan has found a userspace-triggerable WARN in the pagecache code. The series "mm/filemap: Limit page cache size to that supported by xarray" addresses this. The series is marked cc:stable. - Chengming Zhou's series "mm/ksm: cmp_and_merge_page() optimizations and cleanup" cleans up and slightly optimizes KSM. - Roman Gushchin has separated the memcg-v1 and memcg-v2 code - lots of code motion. The series (which also makes the memcg-v1 code Kconfigurable) are "mm: memcg: separate legacy cgroup v1 code and put under config option" and "mm: memcg: put cgroup v1-specific memcg data under CONFIG_MEMCG_V1" - Dan Schatzberg's series "Add swappiness argument to memory.reclaim" adds an additional feature to this cgroup-v2 control file. - The series "Userspace controls soft-offline pages" from Jiaqi Yan permits userspace to stop the kernel's automatic treatment of excessive correctable memory errors. In order to permit userspace to monitor and handle this situation. - Kefeng Wang's series "mm: migrate: support poison recover from migrate folio" teaches the kernel to appropriately handle migration from poisoned source folios rather than simply panicing. - SeongJae Park's series "Docs/damon: minor fixups and improvements" does those things. - In the series "mm/zsmalloc: change back to per-size_class lock" Chengming Zhou improves zsmalloc's scalability and memory utilization. - Vivek Kasireddy's series "mm/gup: Introduce memfd_pin_folios() for pinning memfd folios" makes the GUP code use FOLL_PIN rather than bare refcount increments. So these paes can first be moved aside if they reside in the movable zone or a CMA block. - Andrii Nakryiko has added a binary ioctl()-based API to /proc/pid/maps for much faster reading of vma information. The series is "query VMAs from /proc/<pid>/maps". - In the series "mm: introduce per-order mTHP split counters" Lance Yang improves the kernel's presentation of developer information related to multisize THP splitting. - Michael Ellerman has developed the series "Reimplement huge pages without hugepd on powerpc (8xx, e500, book3s/64)". This permits userspace to use all available huge page sizes. - In the series "revert unconditional slab and page allocator fault injection calls" Vlastimil Babka removes a performance-affecting and not very useful feature from slab fault injection. * tag 'mm-stable-2024-07-21-14-50' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (411 commits) mm/mglru: fix ineffective protection calculation mm/zswap: fix a white space issue mm/hugetlb: fix kernel NULL pointer dereference when migrating hugetlb folio mm/hugetlb: fix possible recursive locking detected warning mm/gup: clear the LRU flag of a page before adding to LRU batch mm/numa_balancing: teach mpol_to_str about the balancing mode mm: memcg1: convert charge move flags to unsigned long long alloc_tag: fix page_ext_get/page_ext_put sequence during page splitting lib: reuse page_ext_data() to obtain codetag_ref lib: add missing newline character in the warning message mm/mglru: fix overshooting shrinker memory mm/mglru: fix div-by-zero in vmpressure_calc_level() mm/kmemleak: replace strncpy() with strscpy() mm, page_alloc: put should_fail_alloc_page() back behing CONFIG_FAIL_PAGE_ALLOC mm, slab: put should_failslab() back behind CONFIG_SHOULD_FAILSLAB mm: ignore data-race in __swap_writepage hugetlbfs: ensure generic_hugetlb_get_unmapped_area() returns higher address than mmap_min_addr mm: shmem: rename mTHP shmem counters mm: swap_state: use folio_alloc_mpol() in __read_swap_cache_async() mm/migrate: putback split folios when numa hint migration fails ... |

mm: add comments for allocation helpers explaining why they are macros
A number of allocation helper functions were converted into macros to
account them at the call sites. Add a comment for each converted
allocation helper explaining why it has to be a macro and why we typecast
the return value wherever required. The patch also moves

iommu: Resolve fwspec ops automatically
There's no real need for callers to resolve ops from a fwnode in order to then pass both to iommu_fwspec_init() - it's simpler and more sensible for that to resolve the ops itself. This in turn means we can centralise the notion of checking for a present driver, and enforce that fwspecs aren't allocated unless and until we know they will be usable. Also use this opportunity to modernise with some "new" helpers that arrived shortly after this code was first written; the generic fwnode_handle_get() clears up that ugly get/put mismatch, while of_fwnode_handle() can now abstract those open-coded dereferences.

driver core: have match() callback in struct bus_type take a const *
In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

ACPI: Add post_eject to struct acpi_scan_handler for cpu hotplug
struct acpi_scan_handler has a detach callback that is used to remove a driver when a bus is changed. When interacting with an eject-request, the detach callback is called before _EJ0. This means the ACPI processor driver can't use _STA to determine if a CPU has been made not-present, or some of the other _STA bits have been changed. acpi_processor_remove() needs to know the value of _STA after _EJ0 has been called. Add a post_eject callback to struct acpi_scan_handler. This is called after acpi_scan_hot_remove() has successfully called _EJ0. Because acpi_scan_check_and_detach() also clears the handler pointer, it needs to be told if the caller will go on to call acpi_bus_post_eject(), so that acpi_device_clear_enumerated() and clearing the handler pointer can be deferred. An extra flag is added to flags field introduced in the previous patch to achieve this.

ACPI: processor: Simplify initial onlining to use same path for cold and hotplug
Separate code paths, combined with a flag set in acpi_processor.c to indicate a struct acpi_processor was for a hotplugged CPU ensured that per CPU data was only set up the first time that a CPU was initialized. This appears to be unnecessary as the paths can be combined by letting the online logic also handle any CPUs online at the time of driver load. Motivation for this change, beyond simplification, is that ARM64 virtual CPU HP uses the same code paths for hotplug and cold path in acpi_processor.c so had no easy way to set the flag for hotplug only. Removing this necessity will enable ARM64 vCPU HP to reuse the existing code paths. Acked-by: Rafael J.

x86/acpi: Add support for CPU offlining for ACPI MADT wakeup method
MADT Multiprocessor Wakeup structure version 1 brings support for CPU offlining: BIOS provides a reset vector where the CPU has to jump to for offlining itself. The new TEST mailbox command can be used to test whether the CPU offlined itself which means the BIOS has control over the CPU and can online it again via the ACPI MADT wakeup method. Add CPU offlining support for the ACPI MADT wakeup method by implementing custom cpu_die(), play_dead() and stop_this_cpu() SMP operations. CPU offlining makes it possible to hand over secondary CPUs over kexec, not limiting the second kernel to a single CPU. The change conforms to the approved ACPI spec change proposal. See the Link.

x86/acpi: Rename fields in the acpi_madt_multiproc_wakeup structure
In order to support MADT wakeup structure version 1, provide more appropriate names for the fields in the structure. Rename 'mailbox_version' to 'version'. This field signifies the version of the structure and the related protocols, rather than the version of the mailbox. This field has not been utilized in the code thus far. Rename 'base_address' to 'mailbox_address' to clarify the kind of address it represents. In version 1, the structure includes the reset vector address. Clear and distinct naming helps to prevent any confusion. Signed-off-by: Kirill A.

ACPI: EC: Evaluate orphan _REG under EC device
After starting to install the EC address space handler at the ACPI
namespace root, if there is an "orphan" _REG method in the EC device's
scope, it will not be evaluated any more. This breaks EC operation
regions on some systems, like Asus gu605.
To address this, use a wrapper around an existing ACPICA function to
look for an "orphan" _REG method in the EC device scope and evaluate
it if present.

Merge branches 'acpi-scan' and 'acpi-tables'
Merge ACPI device enumeration changes and ACPI data-only tables support updates for 6.10: - Rearrange fields in several structures to effectively eliminate computations from container_of() in some cases (Andy Shevchenko). - Do some assorted cleanups of the ACPI device enumeration code (Andy Shevchenko). - Make the ACPI device enumeration code skip devices with _STA values clearly identified by the specification as invalid (Rafael Wysocki). - Rework the handling of the NHLT table to simplify and clarify it and drop some obsolete pieces (Cezary Rojewski). * acpi-scan: ACPI: scan: Avoid enumerating devices with clearly invalid _STA values ACPI: scan: Introduce typedef:s for struct acpi_hotplug_context members ACPI: scan: Use standard error checking pattern ACPI: scan: Move misleading comment to acpi_dma_configure_id() ACPI: scan: Use list_first_entry_or_null() in acpi_device_hid() ACPI: bus: Don't use "proxy" headers ACPI: bus: Make container_of() no-op where it makes sense * acpi-tables: ACPI: NHLT: Streamline struct naming ACPI: NHLT: Drop redundant types ACPI: NHLT: Introduce API for the table ACPI: NHLT: Reintroduce types the table consists of |
