2024-09-02Document/kexec: generalize crash hotplug descriptionSourabh Jain2-6/+6
Commit 79365026f869 ("crash: add a new kexec flag for hotplug support") generalizes the crash hotplug support to allow architectures to update multiple kexec segments on CPU/Memory hotplug and not just elfcorehdr. Therefore, update the relevant kernel documentation to reflect the same. No functional change.

The existing docs here are a bit vague. This reformats and rewords it, and is based upon the wording originally used by the dell-laptop driver battery documentation and also sysfs-class-power-wilco.

2024-08-26optee: probe RPMB device using RPMB subsystemJens Wiklander1-0/+15
Adds support in the OP-TEE drivers (both SMC and FF-A ABIs) to probe and use an RPMB device via the RPMB subsystem instead of passing the RPMB frames via tee-supplicant in user space. A fallback mechanism is kept to route RPMB frames via tee-supplicant if the RPMB subsystem isn't available. The OP-TEE RPC ABI is extended to support iterating over all RPMB devices until one is found with the expected RPMB key already programmed.

In commit 0f718e10da81 ("iio: ABI: add missing calibbias attributes"), the in_resistance_calibbias attribute was added to the main IIO ABI documentation. This attribute is was already documented in sysfs-bus-iio-chemical-sgp40. This resulted in a duplicate entry that is causing documentation build warnings. This removes the attribute from the sgp40 documentation in favor of the main IIO ABI documentation since this attribute fits the established pattern of standard IIO attributes.

2024-08-13cpu/SMT: Enable SMT only if a core is onlineNysal Jan K.A1-1/+2
If a core is offline then enabling SMT should not online CPUs of this core. By enabling SMT, what is intended is either changing the SMT value from "off" to "on" or setting the SMT level (threads per core) from a lower to higher value. On PowerPC the ppc64_cpu utility can be used, among other things, to perform the following functions: ppc64_cpu --cores-on # Get the number of online cores ppc64_cpu --cores-on=X # Put exactly X cores online ppc64_cpu --offline-cores=X[,Y,...] # Put specified cores offline ppc64_cpu --smt={on|off|value} # Enable, disable or change SMT level If the user has decided to offline certain cores, enabling SMT should not online CPUs in those cores. This patch fixes the issue and changes the behaviour as described, by introducing an arch specific function topology_is_core_online(). It is currently implemented only for PowerPC.

2024-08-05f2fs: add write priority option based on zone UFSLiao Yuanhong1-0/+14
Currently, we are using a mix of traditional UFS and zone UFS to support some functionalities that cannot be achieved on zone UFS alone. However, there are some issues with this approach. There exists a significant performance difference between traditional UFS and zone UFS. Under normal usage, we prioritize writes to zone UFS. However, in critical conditions (such as when the entire UFS is almost full), we cannot determine whether data will be written to traditional UFS or zone UFS. This can lead to significant performance fluctuations, which is not conducive to development and testing. To address this, we have added an option zlu_io_enable under sys with the following three modes: 1) zlu_io_enable == 0:Normal mode, prioritize writing to zone UFS; 2) zlu_io_enable == 1:Zone UFS only mode, only allow writing to zone UFS; 3) zlu_io_enable == 2:Traditional UFS priority mode, prioritize writing to traditional UFS.

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. - 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 ...

2024-07-12driver core: auxiliary bus: show auxiliary device IRQsShay Drory1-0/+9
PCI subfunctions (SF) are anchored on the auxiliary bus. PCI physical and virtual functions are anchored on the PCI bus. The irq information of each such function is visible to users via sysfs directory "msi_irqs" containing files for each irq entry. However, for PCI SFs such information is unavailable. Due to this users have no visibility on IRQs used by the SFs. Secondly, an SF can be multi function device supporting rdma, netdevice and more. Without irq information at the bus level, the user is unable to view or use the affinity of the SF IRQs. Hence to match to the equivalent PCI PFs and VFs, add "irqs" directory, for supporting auxiliary devices, containing file for each irq entry. For example: $ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/ 50 51 52 53 54 55 56 57 58 Cc: Simon Horman <horms@kernel.org> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Reviewed-by: Parav Pandit <parav@nvidia.com> Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Shay Drory <shayd@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> --- v9-v10: - remove Przemek RB - add name field to auxiliary_irq_info (Greg and Przemek) - handle bogus IRQ in auxiliary_device_sysfs_irq_remove (Greg) v8-v9: - add Przemek RB - use guard() in auxiliary_irq_dir_prepare (Paolo) v7-v8: - use cleanup.h for info and name fields (Greg) - correct error flow in auxiliary_irq_dir_prepare (Przemek) - add documentation for new fields of auxiliary_device (Simon) v6-v7: - dynamically creating irqs directory when first irq file created (Greg) - removed irqs flag and simplified the dev_add() API (Greg) - move sysfs related new code to a new auxiliary_sysfs.c file (Greg) v5-v6: - removed concept of shared and exclusive and hence global xarray (Greg) v4-v5: - restore global mutex and replace refcount_t with simple integer (Greg) v3->4: - remove global mutex (Przemek) v2->v3: - fix function declaration in case SYSFS isn't defined v1->v2: - move #ifdefs from drivers/base/auxiliary.c to include/linux/auxiliary_bus.h (Greg) - use EXPORT_SYMBOL_GPL instead of EXPORT_SYMBOL (Greg) - Fix kzalloc(ref) to kzalloc(*ref) (Simon) - Add return description in auxiliary_device_sysfs_irq_add() kdoc (Simon) - Fix auxiliary_irq_mode_show doc (kernel test boot)

The CXL driver provides a debugfs interface offering users the ability to inject and clear poison to a memdev. Once a user has injected up to the devices limit further injection requests fail with ENXIO until a clear poison is issued. Users may not have device specs in hand or may want to intentionally hit the limit and then clear. Replace the usual ENXIO return status with EBUSY so users can recognize this failure.

2024-07-04xfs: grant heads track byte counts, not LSNsDave Chinner1-10/+8
The grant heads in the log track the space reserved in the log for running transactions. They do this by tracking how far ahead of the tail that the reservation has reached, and the units for doing this are {cycle,bytes} for the reserve head rather than {cycle,blocks} which are normal used by LSNs. This is annoyingly complex because we have to split, crack and combined these tuples for any calculation we do to determine log space and targets. This is computationally expensive as well as difficult to do atomically and locklessly, as well as limiting the size of the log to 2^32 bytes. Really, though, all the grant heads are tracking is how much space is currently available for use in the log. We can track this as a simply byte count - we just don't care what the actual physical location in the log the head and tail are at, just how much space we have remaining before the head and tail overlap. So, convert the grant heads to track the byte reservations that are active rather than the current (cycle, offset) tuples. This means an empty log has zero bytes consumed, and a full log is when the reservations reach the size of the log minus the space consumed by the AIL. This greatly simplifies the accounting and checks for whether there is space available. We no longer need to crack or combine LSNs to determine how much space the log has left, nor do we need to look at the head or tail of the log to determine how close to full we are. There is, however, a complexity that needs to be handled. We know how much space is being tracked in the AIL now via log->l_tail_space and the log tickets track active reservations and return the unused portions to the grant heads when ungranted. Unfortunately, we don't track the used portion of the grant, so when we transfer log items from the CIL to the AIL, the space accounted to the grant heads is transferred to the log tail space. Hence when we move the AIL head forwards on item insert, we have to remove that space from the grant heads. We also remove the xlog_verify_grant_tail() debug function as it is no longer useful. The check it performs has been racy since delayed logging was introduced, but now it is clearly only detecting false positives so remove it. The result of this substantially simpler accounting algorithm is an increase in sustained transaction rate from ~1.3 million transactions/s to ~1.9 million transactions/s with no increase in CPU usage. We also remove the 32 bit space limitation on the grant heads, which will allow us to increase the journal size beyond 2GB in future. Note that this renames the sysfs files exposing the log grant space now that the values are exported in bytes. This allows xfstests to auto-detect the old or new ABI.

For example, the livepatch without the atomic replace might provide a hotfix or extra tuning. Managing livepatches on such systems might be challenging. And the information which of the installed livepatches do not use the atomic replace would be useful. Add new sysfs interface 'replace'.
