2023-04-06ACPICA: struct acpi_nfit_interleave: Replace 1-element array with flexible arrayKees Cook1-1/+1
ACPICA commit e66decc6fca36b59194b0947d87d6a9bec078bc3 Similar to "Replace one-element array with flexible-array", replace the 1-element array with a proper flexible array member as defined by C99. This allows the code to operate without tripping compile-time and run- time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds, and/or -fstrict-flex-arrays=3). Unlike struct acpi_nfit_flush_address and struct acpi_nfit_smbios, which had their sizeof() uses adjusted in code, struct acpi_nfit_interleave did not. This appears to have been a bug. After this change, there is a binary difference in acpi_dm_dump_nfit() since the size of the structure now has the correct size, as the prior result was including the trailing U32: - mov $0x14,%ebp + mov $0x10,%ebp Link: https://github.com/acpica/acpica/commit/e66decc6 Signed-off-by: Bob Moore <[email protected]> Reviewed-by: Dan Williams <[email protected]> Tested-by: Dan Williams <[email protected]> Signed-off-by: Rafael J.

2023-04-06ACPICA: Headers: Delete bogus node_array array of pointers from AEST tableJessica Clarke1-1/+0
ACPICA commit f0c4a06f1dfc4886d4e0c2aa30bc57b10c5a8c53 Like many tables, this is a header followed by multiple subtables of varying self-identifying types, and ACPICA does not normally add a field for the subtables, instead relying on pointer arithmetic past the end of the first header struct, since indexing a flexible array member is meaningless for variable-length entries. If we really wanted a field for this, we could use a u8 flexible array member, but it contradicts the current style. Using void *, however, is categorically wrong, as ACPI tables never contain native C-language pointers.

This particular combination of flags is used by most filesystems in their ->write_begin method, although it does find use in a few other places. Before folios, it warranted its own function (grab_cache_page_write_begin()), but I think that just having specialised flags is enough. It certainly helps the few places that have been converted from grab_cache_page_write_begin() to __filemap_get_folio().

2023-04-06xsk: Fix unaligned descriptor validationKal Conley1-7/+2
Make sure unaligned descriptors that straddle the end of the UMEM are considered invalid. Currently, descriptor validation is broken for zero-copy mode which only checks descriptors at page granularity. For example, descriptors in zero-copy mode that overrun the end of the UMEM but not a page boundary are (incorrectly) considered valid. The UMEM boundary check needs to happen before the page boundary and contiguity checks in xp_desc_crosses_non_contig_pg(). Do this check in xp_unaligned_validate_desc() instead like xp_check_unaligned() already does.

2023-04-06ASoC: SOF: Intel: hda-mlink: add helpers to set link SYNC frequencyPierre-Louis Bossart1-0/+27
These helpers configure the ratio between the base clock and the hardware signal used for link synchronization. The SYNCPRD is written before the first sublink is powered-up. The SYNCPU bit is set, but it will only be cleared after the link is powered-up, hence the implementation with a set/wait pattern. These helpers are currently only needed by SoundWire support, where the lock is taken at a higher level, so only the _unlocked versions are exposed for now. Note that the _wait_bit() implementation is similar to previous helpers in drivers/soundwire, but with sleep duration and timeout aligned with hardware recommendations. If desired, this helper could be modified in a second step with e.g. readl_poll_timeout().

2023-04-06ASoC: SOF: Intel: hda-mlink: introduce helpers for 'extended links' PMPierre-Louis Bossart1-0/+32
Add helpers to program SPA/CPA bits, using a mutex to access the shared LCTL register if required. All links are managed with the same LCTLx.SPA bits. However there are quite a few implementation details to be aware of: Legacy HDaudio multi-links are powered-up when exiting reset, which requires the ref_count to be manually set to one when initializing the link. Alternate links for SoundWire/DMIC/SSP need to be explicitly powered-up before accessing the SHIM/IP/Vendor-Specific SHIM space for each sublink. DMIC/SSP/SoundWire are all different cases with a different device/dai/hlink relationship. SoundWire will handle power management with the auxiliary device resume/suspend routine. The ref_count is not necessary in this case. The DMIC/SSP will by contrast handle the power management from DAI .startup and .shutdown callbacks. The SSP has a 1:1 mapping between sublink and DAI, but it's bidirectional so the ref_count will help avoid turning off the sublink when one of the two directions is still in use. The DMIC has a single link but two DAIs for data generated at different sampling frequencies, again the ref_count will make sure the two DAIs can be used concurrently. And last the SoundWire Intel require power-up/down and bank switch to be handled with a lock already taken, so the 'eml_lock' is made optional with the _unlocked versions of the helpers. Note that the _check_power_active() implementation is similar to previous helpers in sound/hda/ext, with sleep duration and timeout aligned with hardware recommendations. If desired, this helper could be modified in a second step with .e.g. readl_poll_timeout() Signed-off-by: Pierre-Louis Bossart <[email protected]> Reviewed-by: Rander Wang <[email protected]> Reviewed-by: Péter Ujfalusi <[email protected]> Reviewed-by: Ranjani Sridharan <[email protected]> Signed-off-by: Peter Ujfalusi <[email protected]> Reviewed-by: Takashi Iwai <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Mark Brown <[email protected]>
2023-04-06ASoC: SOF: Intel: hda-mlink: add structures to parse ALT linksPierre-Louis Bossart1-2/+2
Extend hdac_ext_link to store information needed for ALT links. Follow-up patches will include more functional patches for power-up and down. Note that this patch suggests the use of an 'eml_lock' to serialize access to shared registers. SoundWire-specific sequence require the lock to be taken at a higher level, as a result the helpers added in follow-up patches will provide 'unlocked' versions when needed. Also note that the low-level sequences with the 'hdaml_' prefix are taken directly from the hardware specifications - naming conventions included. The code will be split in two, with locking and linked-list management handled separately to avoid mixing required hardware setup and Linux-based resource management.

2023-04-06pwm: stm32: Enforce settings for PWM captureOlivier Moysan1-0/+1
The PWM capture assumes that the input selector is set to default input and that the slave mode is disabled. Force reset state for TISEL and SMCR registers to match this requirement. Note that slave mode disabling is not a pre-requisite by itself for capture mode, as hardware supports it for PWM capture. However, the current implementation of the driver does not allow slave mode for PWM capture. Setting slave mode for PWM capture results in wrong capture values.

2023-04-05sched/numa: implement access PID reset logicRaghavendra K T2-3/+4
This helps to ensure that only recently accessed PIDs scan the VMAs. Current implementation: (idea supported by PeterZ) 1. Accessing PID information is maintained in two windows. access_pids[1] being newest. 2. Reset old access PID info i.e. access_pid[0] every (4 * sysctl_numa_balancing_scan_delay) interval after initial scan delay period expires. The above interval seemed to be experimentally optimum since it avoids frequent reset of access info as well as helps clearing the old access info regularly. The reset logic is implemented in scan path.
