Linus Torvalds	c5d9ab85eb	f2fs update for 6.9-rc1 ... In this round, there are a number of updates on mainly two areas: Zoned block device support and Per-file compression. For example, we've found several issues to support Zoned block device especially having large sections regarding to GC and file pinning used for Android devices. In compression side, we've fixed many corner race conditions that had broken the design assumption. Enhancement: - Support file pinning for Zoned block device having large section - Enhance the data recovery after sudden power cut on Zoned block device - Add more error injection cases to easily detect the kernel panics - add a proc entry show the entire disk layout - Improve various error paths paniced by BUG_ON in block allocation and GC - support SEEK_DATA and SEEK_HOLE for compression files Bug fix: - fix to avoid use-after-free issue in f2fs_filemap_fault - fix some race conditions to break the atomic write design assumption - fix to truncate meta inode pages forcely - resolve various per-file compression issues wrt the space management and compression policies - fix some swap-related bugs In addition, we removed deprecated codes such as io_bits and heap_allocation, and also fixed minor error handling routines with neat debugging messages. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmX4gS0ACgkQQBSofoJI UNLmgBAAg4mvbWjmJ5VbXs4zGLOgLRJYcY1sZRO5Ufg4LhWzoGRxL1Dru+TELw0t 1Ck2EQvP91XZ5weA5AZOfWbxcijy4+8L3P8L7ohOShudfACci0wQsx6IaUUWWylC ILA4+DkovpZrlu6th12Gj9QAM6TN9gdy3V1VLT5O/KmE1x6Pekwp2hQoIvVJRH5L I3KxOf5fTe3oWLvEN6m7yCz/8qGqz8+w0ae90UG0fqi0wVEuZJ99zsVPnuhu6uBo riFm2A6ra0I/JqoPyqn2QM6ApItM867ULo9EoyQVgq56Q1w31ENOJXsU9N7N4Wxt olgujH1SijkWk9ni57iKtMhR68e3Rs+pVsuNFmJuOPq0HASoggB66QRrVvCgM9JG z3D//CB2ONtX2XiKJMiTcX9VqIqrMw6L1eVxEZu0P96C3CS70MoBU69mdSR9Og2S 5nQXja3yzFhdk3thp6+wAJ3I04ZQkf3qoHZB+0chU2Xl1pV+5NIkBgBsSw8g/TY3 EIHMfK+TX0SBSNCvkUDEJ+Z8ZRID6tcbAquTSsBr6wxB+F9mq7onEvI8O7xwyH9W DU8xhymOE2QUoluNtyW7ww6HK913ripXIenI9LaYJnuj0XeDAcMIoPsgR7AGU5UG hshvirFdUdWRMTfXxNNUrvhOWI0qurQSVx+VV6Qb62DGqR5ofOw= =Qpvy -----END PGP SIGNATURE----- Merge tag 'f2fs-for-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs update from Jaegeuk Kim: "In this round, there are a number of updates on mainly two areas: Zoned block device support and Per-file compression.

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

Linus Torvalds	902861e34c	- Sumanth Korikkar has taught s390 to allocate hotplug-time page frames ... from hotplugged memory rather than only from main memory. Series "implement "memmap on memory" feature on s390". - More folio conversions from Matthew Wilcox in the series "Convert memcontrol charge moving to use folios" "mm: convert mm counter to take a folio" - Chengming Zhou has optimized zswap's rbtree locking, providing significant reductions in system time and modest but measurable reductions in overall runtimes. The series is "mm/zswap: optimize the scalability of zswap rb-tree". - Chengming Zhou has also provided the series "mm/zswap: optimize zswap lru list" which provides measurable runtime benefits in some swap-intensive situations. - And Chengming Zhou further optimizes zswap in the series "mm/zswap: optimize for dynamic zswap_pools". Measured improvements are modest. - zswap cleanups and simplifications from Yosry Ahmed in the series "mm: zswap: simplify zswap_swapoff()". - In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has contributed several DAX cleanups as well as adding a sysfs tunable to control the memmap_on_memory setting when the dax device is hotplugged as system memory. - Johannes Weiner has added the large series "mm: zswap: cleanups", which does that. - More DAMON work from SeongJae Park in the series "mm/damon: make DAMON debugfs interface deprecation unignorable" "selftests/damon: add more tests for core functionalities and corner cases" "Docs/mm/damon: misc readability improvements" "mm/damon: let DAMOS feeds and tame/auto-tune itself" - In the series "mm/mempolicy: weighted interleave mempolicy and sysfs extension" Rakie Kim has developed a new mempolicy interleaving policy wherein we allocate memory across nodes in a weighted fashion rather than uniformly. This is beneficial in heterogeneous memory environments appearing with CXL. - Christophe Leroy has contributed some cleanup and consolidation work against the ARM pagetable dumping code in the series "mm: ptdump: Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute". - Luis Chamberlain has added some additional xarray selftesting in the series "test_xarray: advanced API multi-index tests". - Muhammad Usama Anjum has reworked the selftest code to make its human-readable output conform to the TAP ("Test Anything Protocol") format. Amongst other things, this opens up the use of third-party tools to parse and process out selftesting results. - Ryan Roberts has added fork()-time PTE batching of THP ptes in the series "mm/memory: optimize fork() with PTE-mapped THP". Mainly targeted at arm64, this significantly speeds up fork() when the process has a large number of pte-mapped folios. - David Hildenbrand also gets in on the THP pte batching game in his series "mm/memory: optimize unmap/zap with PTE-mapped THP". It implements batching during munmap() and other pte teardown situations. The microbenchmark improvements are nice. - And in the series "Transparent Contiguous PTEs for User Mappings" Ryan Roberts further utilizes arm's pte's contiguous bit ("contpte mappings"). Kernel build times on arm64 improved nicely. Ryan's series "Address some contpte nits" provides some followup work. - In the series "mm/hugetlb: Restore the reservation" Breno Leitao has fixed an obscure hugetlb race which was causing unnecessary page faults. He has also added a reproducer under the selftest code. - In the series "selftests/mm: Output cleanups for the compaction test", Mark Brown did what the title claims. - Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring". - Even more zswap material from Nhat Pham. The series "fix and extend zswap kselftests" does as claimed. - In the series "Introduce cpu_dcache_is_aliasing() to fix DAX regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in our handling of DAX on archiecctures which have virtually aliasing data caches. The arm architecture is the main beneficiary. - Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic improvements in worst-case mmap_lock hold times during certain userfaultfd operations. - Some page_owner enhancements and maintenance work from Oscar Salvador in his series "page_owner: print stacks and their outstanding allocations" "page_owner: Fixup and cleanup" - Uladzislau Rezki has contributed some vmalloc scalability improvements in his series "Mitigate a vmap lock contention". It realizes a 12x improvement for a certain microbenchmark. - Some kexec/crash cleanup work from Baoquan He in the series "Split crash out from kexec and clean up related config items". - Some zsmalloc maintenance work from Chengming Zhou in the series "mm/zsmalloc: fix and optimize objects/page migration" "mm/zsmalloc: some cleanup for get/set_zspage_mapping()" - Zi Yan has taught the MM to perform compaction on folios larger than order=0. This a step along the path to implementaton of the merging of large anonymous folios. The series is named "Enable >0 order folio memory compaction". - Christoph Hellwig has done quite a lot of cleanup work in the pagecache writeback code in his series "convert write_cache_pages() to an iterator". - Some modest hugetlb cleanups and speedups in Vishal Moola's series "Handle hugetlb faults under the VMA lock". - Zi Yan has changed the page splitting code so we can split huge pages into sizes other than order-0 to better utilize large folios. The series is named "Split a folio to any lower order folios". - David Hildenbrand has contributed the series "mm: remove total_mapcount()", a cleanup. - Matthew Wilcox has sought to improve the performance of bulk memory freeing in his series "Rearrange batched folio freeing". - Gang Li's series "hugetlb: parallelize hugetlb page init on boot" provides large improvements in bootup times on large machines which are configured to use large numbers of hugetlb pages. - Matthew Wilcox's series "PageFlags cleanups" does that. - Qi Zheng's series "minor fixes and supplement for ptdesc" does that also. S390 is affected. - Cleanups to our pagemap utility functions from Peter Xu in his series "mm/treewide: Replace pXd_large() with pXd_leaf()". - Nico Pache has fixed a few things with our hugepage selftests in his series "selftests/mm: Improve Hugepage Test Handling in MM Selftests". - Also, of course, many singleton patches to many things. Please see the individual changelogs for details. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCZfJpPQAKCRDdBJ7gKXxA joxeAP9TrcMEuHnLmBlhIXkWbIR4+ki+pA3v+gNTlJiBhnfVSgD9G55t1aBaRplx TMNhHfyiHYDTx/GAV9NXW84tasJSDgA= =TG55 -----END PGP SIGNATURE----- Merge tag 'mm-stable-2024-03-13-20-04' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - Sumanth Korikkar has taught s390 to allocate hotplug-time page frames from hotplugged memory rather than only from main memory.

Measured improvements are modest. - zswap cleanups and simplifications from Yosry Ahmed in the series "mm: zswap: simplify zswap_swapoff()". - In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has contributed several DAX cleanups as well as adding a sysfs tunable to control the memmap_on_memory setting when the dax device is hotplugged as system memory. - Johannes Weiner has added the large series "mm: zswap: cleanups", which does that. - More DAMON work from SeongJae Park in the series "mm/damon: make DAMON debugfs interface deprecation unignorable" "selftests/damon: add more tests for core functionalities and corner cases" "Docs/mm/damon: misc readability improvements" "mm/damon: let DAMOS feeds and tame/auto-tune itself" - In the series "mm/mempolicy: weighted interleave mempolicy and sysfs extension" Rakie Kim has developed a new mempolicy interleaving policy wherein we allocate memory across nodes in a weighted fashion rather than uniformly. This is beneficial in heterogeneous memory environments appearing with CXL. - Christophe Leroy has contributed some cleanup and consolidation work against the ARM pagetable dumping code in the series "mm: ptdump: Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute". - Luis Chamberlain has added some additional xarray selftesting in the series "test_xarray: advanced API multi-index tests". - Muhammad Usama Anjum has reworked the selftest code to make its human-readable output conform to the TAP ("Test Anything Protocol") format. Amongst other things, this opens up the use of third-party tools to parse and process out selftesting results. - Ryan Roberts has added fork()-time PTE batching of THP ptes in the series "mm/memory: optimize fork() with PTE-mapped THP". Mainly targeted at arm64, this significantly speeds up fork() when the process has a large number of pte-mapped folios. - David Hildenbrand also gets in on the THP pte batching game in his series "mm/memory: optimize unmap/zap with PTE-mapped THP". It implements batching during munmap() and other pte teardown situations. The microbenchmark improvements are nice. - And in the series "Transparent Contiguous PTEs for User Mappings" Ryan Roberts further utilizes arm's pte's contiguous bit ("contpte mappings"). Kernel build times on arm64 improved nicely. Ryan's series "Address some contpte nits" provides some followup work. - In the series "mm/hugetlb: Restore the reservation" Breno Leitao has fixed an obscure hugetlb race which was causing unnecessary page faults. He has also added a reproducer under the selftest code. - In the series "selftests/mm: Output cleanups for the compaction test", Mark Brown did what the title claims. - Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring". - Even more zswap material from Nhat Pham. The series "fix and extend zswap kselftests" does as claimed. - In the series "Introduce cpu_dcache_is_aliasing() to fix DAX regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in our handling of DAX on archiecctures which have virtually aliasing data caches. The arm architecture is the main beneficiary. - Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic improvements in worst-case mmap_lock hold times during certain userfaultfd operations. - Some page_owner enhancements and maintenance work from Oscar Salvador in his series "page_owner: print stacks and their outstanding allocations" "page_owner: Fixup and cleanup" - Uladzislau Rezki has contributed some vmalloc scalability improvements in his series "Mitigate a vmap lock contention". It realizes a 12x improvement for a certain microbenchmark. - Some kexec/crash cleanup work from Baoquan He in the series "Split crash out from kexec and clean up related config items". - Some zsmalloc maintenance work from Chengming Zhou in the series "mm/zsmalloc: fix and optimize objects/page migration" "mm/zsmalloc: some cleanup for get/set_zspage_mapping()" - Zi Yan has taught the MM to perform compaction on folios larger than order=0. This a step along the path to implementaton of the merging of large anonymous folios. The series is named "Enable >0 order folio memory compaction". - Christoph Hellwig has done quite a lot of cleanup work in the pagecache writeback code in his series "convert write_cache_pages() to an iterator". - Some modest hugetlb cleanups and speedups in Vishal Moola's series "Handle hugetlb faults under the VMA lock". - Zi Yan has changed the page splitting code so we can split huge pages into sizes other than order-0 to better utilize large folios. The series is named "Split a folio to any lower order folios". - David Hildenbrand has contributed the series "mm: remove total_mapcount()", a cleanup. - Matthew Wilcox has sought to improve the performance of bulk memory freeing in his series "Rearrange batched folio freeing". - Gang Li's series "hugetlb: parallelize hugetlb page init on boot" provides large improvements in bootup times on large machines which are configured to use large numbers of hugetlb pages. - Matthew Wilcox's series "PageFlags cleanups" does that. - Qi Zheng's series "minor fixes and supplement for ptdesc" does that also. S390 is affected. - Cleanups to our pagemap utility functions from Peter Xu in his series "mm/treewide: Replace pXd_large() with pXd_leaf()". - Nico Pache has fixed a few things with our hugepage selftests in his series "selftests/mm: Improve Hugepage Test Handling in MM Selftests". - Also, of course, many singleton patches to many things. Please see the individual changelogs for details. * tag 'mm-stable-2024-03-13-20-04' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (435 commits) mm/zswap: remove the memcpy if acomp is not sleepable crypto: introduce: acomp_is_async to expose if comp drivers might sleep memtest: use {READ,WRITE}_ONCE in memory scanning mm: prohibit the last subpage from reusing the entire large folio mm: recover pud_leaf() definitions in nopmd case selftests/mm: skip the hugetlb-madvise tests on unmet hugepage requirements selftests/mm: skip uffd hugetlb tests with insufficient hugepages selftests/mm: dont fail testsuite due to a lack of hugepages mm/huge_memory: skip invalid debugfs new_order input for folio split mm/huge_memory: check new folio order when split a folio mm, vmscan: retry kswapd's priority loop with cache_trim_mode off on failure mm: add an explicit smp_wmb() to UFFDIO_CONTINUE mm: fix list corruption in put_pages_list mm: remove folio from deferred split list before uncharging it filemap: avoid unnecessary major faults in filemap_fault() mm,page_owner: drop unnecessary check mm,page_owner: check for null stack_record before bumping its refcount mm: swap: fix race between free_swap_and_cache() and swapoff() mm/treewide: align up pXd_leaf() retval across archs mm/treewide: drop pXd_large() ...	2024-03-14 17:43:30 -07:00

Up until now the synchronization in the GPIO subsystem was broken. There was a single spinlock "protecting" multiple data structures but doing it wrong (as evidenced by several places where it would be released when a sleeping function was called and then reacquired without checking the protected state). We tried to use an RW semaphore before but the main issue with GPIO is that we have drivers implementing the interfaces in both sleeping and non-sleeping ways as well as user-facing interfaces that can be called both from process as well as atomic contexts. Both ends converge in the same code paths that can use neither spinlocks nor mutexes. The only reasonable way out is to use SRCU and go mostly lockless. To that end: we add several SRCU structs in relevant places and use them to assure consistency between API calls together with atomic reads and writes of GPIO descriptor flags where it makes sense. This code has spent several weeks in next and has received several fixes in the first week or two after which it stabilized nicely. The GPIO subsystem is now resilient to providers being suddenly unbound. We managed to also remove the existing character device RW semaphore and the obsolete global spinlock. Other than the locking rework we have one new driver (for Chromebook EC), much appreciated documentation improvements from Kent and the regular driver improvements, DT-bindings updates and GPIOLIB core tweaks. Serialization rework: - use SRCU to serialize access to the global GPIO device list, to GPIO device structs themselves and to GPIO descriptors - make the GPIO subsystem resilient to the GPIO providers being unbound while the API calls are in progress - don't dereference the SRCU-protected chip pointer if the information we need can be obtained from the GPIO device structure - move some of the information contained in struct gpio_chip to struct gpio_device to further reduce the need to dereference the former - pass the GPIO device struct instead of the GPIO chip to sysfs callback to, again, reduce the need for accessing the latter - get GPIO descriptors from the GPIO device, not from the chip for the same reason - allow for mostly lockless operation of the GPIO driver API: assure consistency with SRCU and atomic operations - remove the global GPIO spinlock - remove the character device RW semaphore Core GPIOLIB: - constify pointers in GPIO API where applicable - unify the GPIO counting APIs for ACPI and OF - provide a macro for iterating over all GPIOs, not only the ones that are requested - remove leftover typedefs - pass the consumer device to GPIO core in devm_fwnode_gpiod_get_index() for improved logging - constify the GPIO bus type - don't warn about removing GPIO chips with descriptors still held by users as we can now handle this situation gracefully - remove unused logging helpers - unexport functions that are only used internally in the GPIO subsystem - set the device type (assign the relevant struct device_type) for GPIO devices New drivers: - add the ChromeOS EC GPIO driver Driver improvements: - allow building gpio-vf610 with COMPILE_TEST as well as disabling it in menuconfig (before it was always built for i.MX cofigs) - count the number of EICs using the device properties instead of hard-coding it in gpio-eic-sprd - improve the device naming, extend the debugfs output and add lockdep asserts to gpio-sim DT bindings: - document the 'label' property for gpio-pca9570 - convert aspeed,ast2400-gpio bindings to DT schema - disallow unevaluated properties for gpio-mvebu - document a new model in renesas,rcar-gpio Documentation: - improve the character device kerneldocs in user-space headers - add proper documentation for the character device uAPI (both v1 and v2) - move the sysfs and gpio-mockup docs into the "obsolete" section - improve naming consistency for GPIO terms - clarify the line values description for sysfs - minor docs improvements - improve the driver API contract for setting GPIO direction - mark unsafe APIs as deprecated in kerneldocs and suggest replacements Other: - remove an obsolete test from selftests" * tag 'gpio-updates-for-v6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (79 commits) gpio: sysfs: repair export returning -EPERM on 1st attempt selftest: gpio: remove obsolete gpio-mockup test gpiolib: Deduplicate cleanup for-loop in gpiochip_add_data_with_key() dt-bindings: gpio: aspeed,ast2400-gpio: Convert to DT schema gpio: acpi: Make acpi_gpio_count() take firmware node as a parameter gpio: of: Make of_gpio_get_count() take firmware node as a parameter gpiolib: Pass consumer device through to core in devm_fwnode_gpiod_get_index() gpio: sim: use for_each_hwgpio() gpio: provide for_each_hwgpio() gpio: don't warn about removing GPIO chips with active users anymore gpio: sim: delimit the fwnode name with a ":" when generating labels gpio: sim: add lockdep asserts gpio: Add ChromeOS EC GPIO driver gpio: constify of_phandle_args in of_find_gpio_device_by_xlate() gpio: fix memory leak in gpiod_request_commit() gpio: constify opaque pointer "data" in gpio_device_find() gpio: cdev: fix a NULL-pointer dereference with DEBUG enabled gpio: uapi: clarify default_values being logical gpio: sysfs: fix inverted pointer logic gpio: don't let lockdep complain about inherently dangerous RCU usage ...	2024-03-13 11:14:55 -07:00

Linus Torvalds	9187210eee	Networking changes for 6.9. ... Core & protocols ---------------- - Large effort by Eric to lower rtnl_lock pressure and remove locks: - Make commonly used parts of rtnetlink (address, route dumps etc.) lockless, protected by RCU instead of rtnl_lock. - Add a netns exit callback which already holds rtnl_lock, allowing netns exit to take rtnl_lock once in the core instead of once for each driver / callback. - Remove locks / serialization in the socket diag interface. - Remove 6 calls to synchronize_rcu() while holding rtnl_lock. - Remove the dev_base_lock, depend on RCU where necessary. - Support busy polling on a per-epoll context basis.

Pawan Gupta	8076fcde01	x86/rfds: Mitigate Register File Data Sampling (RFDS) ... RFDS is a CPU vulnerability that may allow userspace to infer kernel stale data previously used in floating point registers, vector registers and integer registers. RFDS only affects certain Intel Atom processors. Intel released a microcode update that uses VERW instruction to clear the affected CPU buffers. Unlike MDS, none of the affected cores support SMT. Add RFDS bug infrastructure and enable the VERW based mitigation by default, that clears the affected buffers just before exiting to userspace. Also add sysfs reporting and cmdline parameter "reg_file_data_sampling" to control the mitigation.

Jakub Kicinski	6025b9135f	net: dqs: add NIC stall detector based on BQL ... softnet_data->time_squeeze is sometimes used as a proxy for host overload or indication of scheduling problems. In practice this statistic is very noisy and has hard to grasp units - e.g. is 10 squeezes a second to be expected, or high? Delaying network (NAPI) processing leads to drops on NIC queues but also RTT bloat, impacting pacing and CA decisions. Stalls are a little hard to detect on the Rx side, because there may simply have not been any packets received in given period of time. Packet timestamps help a little bit, but again we don't know if packets are stale because we're not keeping up or because someone (*cough* cgroups) disabled IRQs for a long time. We can, however, use Tx as a proxy for Rx stalls. Most drivers use combined Rx+Tx NAPIs so if Tx gets starved so will Rx. On the Tx side we know exactly when packets get queued, and completed, so there is no uncertainty. This patch adds stall checks to BQL. Why BQL? Because it's a convenient place to add such checks, already called by most drivers, and it has copious free space in its structures (this patch adds no extra cache references or dirtying to the fast path). The algorithm takes one parameter - max delay AKA stall threshold and increments a counter whenever NAPI got delayed for at least that amount of time. It also records the length of the longest stall. To be precise every time NAPI has not polled for at least stall thrs we check if there were any Tx packets queued between last NAPI run and now - stall_thrs/2. Unlike the classic Tx watchdog this mechanism does not ignore stalls caused by Tx being disabled, or loss of link. I don't think the check is worth the complexity, and stall is a stall, whether due to host overload, flow control, link down... doesn't matter much to the application. We have been running this detector in production at Meta for 2 years, with the threshold of 8ms. It's the lowest value where false positives become rare. There's still a constant stream of reported stalls (especially without the ksoftirqd deferral patches reverted), those who like their stall metrics to be 0 may prefer higher value.

Elbert Mai	12fc84e8c4	usb: Export BOS descriptor to sysfs ... Motivation ---------- The binary device object store (BOS) of a USB device consists of the BOS descriptor followed by a set of device capability descriptors. One that is of interest to users is the platform descriptor. This contains a 128-bit UUID and arbitrary data, and it allows parties outside of USB-IF to add additional metadata about a USB device in a standards-compliant manner. Notable examples include the WebUSB and Microsoft OS 2.0 descriptors. The kernel already retrieves and caches the BOS from USB devices if its bcdUSB is >= 0x0201. Because the BOS is flexible and extensible, we export the entire BOS to sysfs so users can retrieve whatever device capabilities they desire, without requiring USB I/O or elevated permissions. Implementation -------------- Add bos_descriptors attribute to sysfs. This is a binary file and it works the same way as the existing descriptors attribute. The file exists only if the BOS is present in the USB device. Also create a binary attribute group, so the driver core can handle the creation of both the descriptors and bos_descriptors attributes in sysfs.

Stefan Hajnoczi	a8f62f50b4	virtiofs: export filesystem tags through sysfs ... The virtiofs filesystem is mounted using a "tag" which is exported by the virtiofs device: # mount -t virtiofs <tag> /mnt The virtiofs driver knows about all the available tags but these are currently not exported to user space. People have asked for these tags to be exported to user space. Most recently Lennart Poettering has asked for it as he wants to scan the tags and mount virtiofs automatically in certain cases. https://gitlab.com/virtio-fs/virtiofsd/-/issues/128 This patch exports tags at /sys/fs/virtiofs/<N>/tag where N is the id of the virtiofs device. The filesystem tag can be obtained by reading this "tag" file. There is also a symlink at /sys/fs/virtiofs/<N>/device that points to the virtiofs device that exports this tag. This patch converts the existing struct virtio_fs into a full kobject. It already had a refcount so it's an easy change. The virtio_fs objects can then be exposed in a kset at /sys/fs/virtiofs/. Note that virtio_fs objects may live slightly longer than we wish for them to be exposed to userspace, so kobject_del() is called explicitly when the underlying virtio_device is removed. The virtio_fs object is freed when all references are dropped (e.g. active mounts) but disappears as soon as the virtiofs device is gone.

Anshuman Khandual	b9ad003af1	mm/cma: add sysfs file 'release_pages_success' ... This adds the following new sysfs file tracking the number of successfully released pages from a given CMA heap area. This file will be available via CONFIG_CMA_SYSFS and help in determining active CMA pages available on the CMA heap area. This adds a new 'nr_pages_released' (CONFIG_CMA_SYSFS) into 'struct cma' which gets updated during cma_release(). /sys/kernel/mm/cma/<cma-heap-area>/release_pages_success After this change, an user will be able to find active CMA pages available in a given CMA heap area via the following method. Active pages = alloc_pages_success - release_pages_success That's valuable information for both software designers, and system admins as it allows them to tune the number of CMA pages available in the system. This increases user visibility for allocated CMA area and its utilization.

Rakie Kim	dce41f5ae2	mm/mempolicy: implement the sysfs-based weighted_interleave interface ... Patch series "mm/mempolicy: weighted interleave mempolicy and sysfs extension", v5. Weighted interleave is a new interleave policy intended to make use of heterogeneous memory environments appearing with CXL. The existing interleave mechanism does an even round-robin distribution of memory across all nodes in a nodemask, while weighted interleave distributes memory across nodes according to a provided weight. (Weight = # of page allocations per round) Weighted interleave is intended to reduce average latency when bandwidth is pressured - therefore increasing total throughput. In other words: It allows greater use of the total available bandwidth in a heterogeneous hardware environment (different hardware provides different bandwidth capacity). As bandwidth is pressured, latency increases - first linearly and then exponentially. By keeping bandwidth usage distributed according to available bandwidth, we therefore can reduce the average latency of a cacheline fetch. A good explanation of the bandwidth vs latency response curve: https://mahmoudhatem.wordpress.com/2017/11/07/memory-bandwidth-vs-latency-response-curve/ From the article: ``` Constant region: The latency response is fairly constant for the first 40% of the sustained bandwidth. Linear region: In between 40% to 80% of the sustained bandwidth, the latency response increases almost linearly with the bandwidth demand of the system due to contention overhead by numerous memory requests. Exponential region: Between 80% to 100% of the sustained bandwidth, the memory latency is dominated by the contention latency which can be as much as twice the idle latency or more. Maximum sustained bandwidth : Is 65% to 75% of the theoretical maximum bandwidth. ``` As a general rule of thumb: * If bandwidth usage is low, latency does not increase. It is optimal to place data in the nearest (lowest latency) device. * If bandwidth usage is high, latency increases. It is optimal to place data such that bandwidth use is optimized per-device. This is the top line goal: Provide a user a mechanism to target using the "maximum sustained bandwidth" of each hardware component in a heterogenous memory system. For example, the stream benchmark demonstrates that 1:1 (default) interleave is actively harmful, while weighted interleave can be beneficial. Default interleave distributes data such that too much pressure is placed on devices with lower available bandwidth. Stream Benchmark (vs DRAM, 1 Socket + 1 CXL Device) Default interleave : -78% (slower than DRAM) Global weighting : -6% to +4% (workload dependant) Targeted weights : +2.5% to +4% (consistently better than DRAM) Global means the task-policy was set (set_mempolicy), while targeted means VMA policies were set (mbind2). We see weighted interleave is not always beneficial when applied globally, but is always beneficial when applied to bandwidth-driving memory regions. There are 4 patches in this set: 1) Implement system-global interleave weights as sysfs extension in mm/mempolicy.c. These weights are RCU protected, and a default weight set is provided (all weights are 1 by default). In future work, we intend to expose an interface for HMAT/CDAT code to set reasonable default values based on the memory configuration of the system discovered at boot/hotplug. 2) A mild refactor of some interleave-logic for re-use in the new weighted interleave logic. 3) MPOL_WEIGHTED_INTERLEAVE extension for set_mempolicy/mbind 4) Protect interleave logic (weighted and normal) with the mems_allowed seq cookie. If the nodemask changes while accessing it during a rebind, just retry the access.

Add a sysfs knob for dax devices to control the memmap_on_memory setting if the dax device were to be hotplugged as system memory. The default memmap_on_memory setting for dax devices originating via pmem or hmem is set to 'false' - i.e. no memmap_on_memory semantics, to preserve legacy behavior. For dax devices via CXL, the default is on. The sysfs control allows the administrator to override the above defaults if needed.

Mark Brown	b96ccdcf9d	ASoC: Intel: avs: Fixes and new platforms support ... Merge series from Cezary Rojewski <cezary.rojewski@intel.com>: The avs-driver continues to be utilized on more recent Intel machines. As TGL-based (cAVS 2.5) e.g.: RPL, inherit most of the functionality from previous platforms: SKL <- APL <- CNL <- ICL <- TGL rather than putting everything into a single file, the platform-specific bits are split into cnl/icl/tgl.c files instead. Makes the division clear and code easier to maintain. Layout of the patchset: First are two changes combined together address the sound-clipping problem, present when only one stream is running - specifically one CAPTURE stream. Follow up is naming-scheme adjustment for some of the existing functions what improves code incohesiveness. As existing IPC/IRQ code operates solely on cAVS 1.5 architecture, it needs no abstraction. The situation changes when newer platforms come into the picture. Thus the next two patches abstract the existing IPC/IRQ handlers so that majority of the common code can be re-used. The ICCMAX change stands out a bit - the AudioDSP firmware loading procedure differs on ICL-based platforms (and onwards) and having a separate commit makes the situation clear to the developers who are going to support the solution from LTS perspective. For that reason I decided not to merge it into the commit introducing the icl.c file.	2024-02-21 00:52:26 +00:00
