2025-05-22regulator: bcm590xx: Store regulator descriptions in tableArtur Weber
Instead of filling in the regulator description programatically, store the data in a struct. This will make it a bit nicer to introduce support for other BCM590xx chips besides the BCM59056. To do this, add a new struct type, bcm590xx_reg_data, to store all of the necessary information. Drop the old IS_LDO, IS_GPLDO... macros in favor of the "type" field in this struct. Adapt the old bcm590xx_reg struct to the new types.

2025-05-22mfd: bcm590xx: Add PMU ID/revision parsing functionArtur Weber
The BCM590xx PMUs have two I2C registers for reading the PMU ID and revision. The revision is useful for subdevice drivers, since different revisions may have slight differences in behavior (for example - BCM59054 has different regulator configurations for revision A0 and A1). Check the PMU ID register and make sure it matches the DT compatible. Fetch the digital and analog revision from the PMUREV register so that it can be used in subdevice drivers. Also add some known revision values to bcm590xx.h, for convenience when writing subdevice drivers.

2025-05-22mfd: bcm590xx: Add support for multiple device types + BCM59054 compatibleArtur Weber
The BCM59054 is another chip from the BCM590xx line of PMUs, commonly used on devices with the BCM21664/BCM23550 chipsets. Prepare the BCM590xx driver for supporting other devices by adding the PMUID register values for supported chip types and store them in the MFD data struct as "pmu_id". (These will be checked against the actual PMUID register values in a later commit.) Then, add a DT compatible for the BCM59054, and provide the PMU ID as OF match data.

This test reproduces a scenario where HFSC queue length and backlog accounting can become inconsistent when a peek operation triggers a dequeue and possible drop before the parent qdisc updates its counters. The test sets up a DRR root qdisc with an HFSC class, netem, and blackhole children, and uses Scapy to inject a packet.

2025-05-22sch_hfsc: Fix qlen accounting bug when using peek in hfsc_enqueue()Cong Wang
When enqueuing the first packet to an HFSC class, hfsc_enqueue() calls the child qdisc's peek() operation before incrementing sch->q.qlen and sch->qstats.backlog. If the child qdisc uses qdisc_peek_dequeued(), this may trigger an immediate dequeue and potential packet drop. In such cases, qdisc_tree_reduce_backlog() is called, but the HFSC qdisc's qlen and backlog have not yet been updated, leading to inconsistent queue accounting. This can leave an empty HFSC class in the active list, causing further consequences like use-after-free. This patch fixes the bug by moving the increment of sch->q.qlen and sch->qstats.backlog before the call to the child qdisc's peek() operation. This ensures that queue length and backlog are always accurate when packet drops or dequeues are triggered during the peek.

2025-05-22i2c: atr: add passthrough flagCosmin Tanislav
Some I2C ATRs can have other I2C ATRs as children. The I2C messages of the child ATRs need to be forwarded as-is if the parent I2C ATR can only do static mapping. In the case of GMSL, the deserializer I2C ATR actually doesn't have I2C address remapping hardware capabilities, but it is able to select which GMSL link to talk to, allowing it to change the address of the serializer. The child ATRs need to have their alias pools defined in such a way to prevent overlapping addresses between them, but there's no way around this without orchestration between multiple ATR instances. To allow for this use-case, add a flag that allows unmapped addresses to be passed through, since they are already remapped by the child ATRs. There's no case where an address that has not been remapped by the child ATR will hit the parent ATR.

When applying a recent commit to the <uapi/linux/perf_event.h> header I noticed that we have accumulated quite a bit of historic noise in this header, so do a bit of spring cleaning: - Define bitfields in a vertically aligned fashion, like perf_event_mmap_page::capabilities already does. This makes it easier to see the distribution and sizing of bits within a word, at a glance. The following is much more readable: __u64 cap_bit0 : 1, cap_bit0_is_deprecated : 1, cap_user_rdpmc : 1, cap_user_time : 1, cap_user_time_zero : 1, cap_user_time_short : 1, cap_____res : 58; Than: __u64 cap_bit0:1, cap_bit0_is_deprecated:1, cap_user_rdpmc:1, cap_user_time:1, cap_user_time_zero:1, cap_user_time_short:1, cap_____res:58; So convert all bitfield definitions from the latter style to the former style. - Fix typos and grammar - Fix capitalization - Remove whitespace noise - Harmonize the definitions of various generations and groups of PERF_MEM_ ABI values. - Vertically align all definitions and assignments to the same column (48), as the first definition (enum perf_type_id), throughout the entire header. - And in general make the code and comments to be more in sync with each other and to be more readable overall. No change in functionality. Copy the changes over to tools/include/uapi/linux/perf_event.h.

2025-05-22gfs2: No more gfs2_find_jhead cachingAndreas Gruenbacher
We are no longer calling gfs2_find_jhead() on the same log twice, so there is no more reason for keeping the log contents cached across those calls. In addition, log head lookup and log header writing didn't go through the same address space and so the caching wasn't even fully working, anyway.

2025-05-22gfs2: Get rid of duplicate log head lookupAndreas Gruenbacher
Currently at mount time, the recovery code looks up the current log head and, if necessary, replays the log and writes a recovery header to indicate that the log is clean. It does that for each log that may need recovery. We also know that our own log will always be checked as part of that process. Then, the mount code looks up the log head of our own log again. The double log head lookup can be costly, but more importantly, it is unnecessary because we can trivially compute the position of the log head after recovery; all we need to do for that is bump the position and lh_sequence by one when writing a recovery header. With that in mind, move the call to gfs2_log_pointers_init() into gfs2_recover_func() and get rid of the double lookup in gfs2_make_fs_rw(). Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>

2025-05-22gfs2: Simplify gfs2_log_pointers_initAndreas Gruenbacher
Move the initialization of sdp->sd_log_sequence and sdp->sd_log_flush_head inside gfs2_log_pointers_init(). Use gfs2_replay_incr_blk(). Before this change, the log head lookup code in freeze_go_xmote_bh() didn't update sdp->sd_log_flush_head. This is now fixed, but the code in freeze_go_xmote_bh() appears to be pretty useless in the first place: on a frozen filesystem, the log head will not change.

2025-05-22gfs2: Don't start unnecessary transactions during log flushAndreas Gruenbacher
Commit 8d391972ae2d ("gfs2: Remove __gfs2_writepage()") changed the log flush code in gfs2_ail1_start_one() to call aops->writepages() instead of aops->writepage(). For jdata inodes, this means that we will now try to reserve log space and start a transaction before we can determine that the pages in question have already been journaled. When this happens in the context of gfs2_logd(), it can now appear that not enough log space is available for freeing up log space, and we will lock up. Fix that by issuing journal writes directly instead of going through aops->writepages() in the log flush code.

2025-05-22gfs2: avoid inefficient use of crc32_le_shift()Eric Biggers
__get_log_header() was using crc32_le_shift() to update a CRC with four zero bytes. However, this is about 5x slower than just CRC'ing four zero bytes in the normal way. Just do that instead. (We could instead make crc32_le_shift() faster on short lengths. But all its callers do just fine without it, so I'd like to just remove it.)

2025-05-22gfs2: Do not call iomap_zero_range beyond eofAndreas Gruenbacher
Since commit eb65540aa9fc ("iomap: warn on zero range of a post-eof folio"), iomap_zero_range() warns when asked to zero a folio beyond eof. The warning triggers on the following code path: gfs2_fallocate(FALLOC_FL_PUNCH_HOLE | FALLOC_FL_KEEP_SIZE) __gfs2_punch_hole() gfs2_block_zero_range() iomap_zero_range() In __gfs2_punch_hole(), gfs2 zeroes out partial folios at the beginning and at the end of the specified range, whether those folios are beyond eof or not. This may add folios to the page cache which are entirely beyond eof, which isn't of any use. Avoid that by truncating the range to zero out at eof.

2025-05-22iommu: Skip PASID validation for devices without PASID capabilityTushar Dave
Generally PASID support requires ACS settings that usually create single device groups, but there are some niche cases where we can get multi-device groups and still have working PASID support. The primary issue is that PCI switches are not required to treat PASID tagged TLPs specially so appropriate ACS settings are required to route all TLPs to the host bridge if PASID is going to work properly. pci_enable_pasid() does check that each device that will use PASID has the proper ACS settings to achieve this routing. However, no-PASID devices can be combined with PASID capable devices within the same topology using non-uniform ACS settings. In this case the no-PASID devices may not have strict route to host ACS flags and end up being grouped with the PASID devices. This configuration fails to allow use of the PASID within the iommu core code which wrongly checks if the no-PASID device supports PASID. Fix this by ignoring no-PASID devices during the PASID validation. They will never issue a PASID TLP anyhow so they can be ignored.

SPI and I2C into the tas2781_hda lib Calibration data getting function for SPI and I2C HDA drivers are almost same, which read the calibration data from UEFI. To put them into tas2781_hda lib for code cleanup is more reasonable than to still keep them in the codec driver. For tas2781 codec driver, there're two different sources for calibrated data, one is from bin file, generated in factory test, requested and read in codec driver side; the other is from user space during device bootup.

2025-05-22drm/i915/dp_mst: Work around Thunderbolt sink disconnect after ↵Imre Deak
SINK_COUNT_ESI read Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT link may get disconnected inadvertently if the SINK_COUNT_ESI and the DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX transaction. Work around the issue by reading these registers in separate transactions. The issue affects MTL+ platforms and will be fixed in the DP-in adapter firmware, however releasing that firmware fix may take some time and is not guaranteed to be available for all systems. Based on this apply the workaround on affected platforms. See HSD #13013007775. v2: Cc'ing Mika Westerberg.
