Pull timekeeping updates from Thomas Gleixner: "Updates for NTP/timekeeping and PTP: - Expand timekeeping snapshot mechanisms The various snapshot functions are mostly used for PTP to collect "atomic" snapshots of various involved clocks. They lack support for the recently introduced AUX clocks and do not provide the underlying counter value (e.g. TSC) to user space. Exposing the counter value snapshot allows for better control and steering. Convert the hard wired ktime_get_snapshot() to take a clock ID, which allows the caller to select the clock ID to be captured along with CLOCK_MONONOTONIC_RAW. Additionally capture the underlying hardware counter value and the clock source ID of the counter. Expand the hardware based snapshot capture where devices provide a mechanism to snapshot the hardware PTP clock and the system counter (usually via PCI/PTM) to support AUX clocks and also provide the captured counter value back to the caller and not only the clock timestamps derived from it. - Add a new optional read_snapshot() callback to clocksources That is required to capture atomic snapshots from clocksources which are derived from TSC with a scaling mechanism (e.g. Hyper-V, KVMclock). The value pair is handed back in the snapshot structure to the callers, so they can do the necessary correlations in a more precise way. This touches usage sites of the affected functions and data structure all over the tree, but stays fully backwards compatible for the existing user space exposed interfaces. New PTP IOCTLs will provide access to the extended functionality in later kernel versions" * tag 'timers-ptp-2026-06-13' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip: (28 commits) ptp: vmclock: Use hw_cycles from snapshot for precise TSC pairing x86/kvmclock: Implement read_snapshot() for kvmclock clocksource clocksource/hyperv: Implement read_snapshot() for TSC page clocksource timekeeping: Add clocksource read_snapshot() method and hw_cycles to snapshot ptp: Switch to ktime_get_snapshot_id() for pre/post timestamps timekeeping: Add support for AUX clock cross timestamping timekeeping: Remove system_device_crosststamp::sys_realtime ALSA: hda/common: Use system_device_crosststamp::sys_systime wifi: iwlwifi: Use system_device_crosststamp::sys_systime ptp: Use system_device_crosststamp::sys_systime timekeeping: Prepare for cross timestamps on arbitrary clock IDs timekeeping: Remove ktime_get_snapshot() virtio_rtc: Use provided clock ID for history snapshot net/mlx5: Use provided clock ID for history snapshot igc: Use provided clock ID for history snapshot ice/ptp: Use provided clock ID for history snapshot wifi: iwlwifi: Adopt PTP cross timestamps to core changes timekeeping: Add CLOCK ID to system_device_crosststamp timekeeping: Add system_counterval_t to struct system_device_crosststamp timekeeping: Add CLOCK_AUX support for ktime_get_snapshot_id() ...

ALSA: hda: Use the new helper for PCM instance refcount

2026-06-11T07:34:09+00:00

HD-audio core driver has some open-code for managing the refcount for PCM instances, and it can be replaced gracefully with the new helpers. Only a code cleanup, no functional changes. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20260610154538.51076-4-tiwai@suse.de

timekeeping: Add CLOCK ID to system_device_crosststamp

2026-06-04T09:04:16+00:00

The normal capture for system/device cross timestamps is CLOCK_REALTIME, but that's meaningless for AUX clocks. Add a clock_id field to struct system_device_crosststamp and initialize it with CLOCK_REALTIME at the two places which prepare for cross timestamps. After the related code has been cleaned up, the core code will honor the clock_id field when calculating the system time from the system counter snapshot. No functional change.

ALSA: hda/hdmi: Use 'AC_PINSENSE_ELDV' to detect pinsense for Loongson

2026-05-27T16:06:16+00:00

Due to a hardware defect, for Loongson PCI HDMI devices with a reversion ID of 2, the pin sense status must be determined via the ELD. Add a codec flag, eld_jack_detect, to indicate this case, and do special handlings in read_pin_sense().

ALSA: hda/intel: Make sure to cancel irq-pending work at closing PCM stream

2026-05-20T05:50:45+00:00

The pending irq work might be still floating while the assigned stream has been already closed, which may lead to UAF, especially when another async work for fasync is involved. For addressing this, extend the hda_controller_ops for allowing the extra cleanup procedure that is specific to the controller driver, and make sure to cancel and sync the pending irq work at each PCM close before releasing the resources.

ALSA: hda: Move irq pending work into hda-intel stream

2026-05-20T05:50:45+00:00

Currently, the delayed IRQ handling for PCM streams is managed in a single work embedded in hda_intel, but this is basically a per-stream thing. Due to the single work, we can't cancel the work properly at closing each stream, for example. For making the IRQ pending work to be stream-based, this patch changes the following: - An extended version of azx_dev (i.e. the hd-audio stream object) is defined for snd-hda-intel - The irq_pending flag and irq_pending_work are moved to hda_intel_stream, so that they can be hda-intel stream specific - The stream creation and assignment are refactored so that snd-hda-intel can handle individually; the snd-hda-intel specific workaround for stream tags is also moved to snd-hda-intel itself instead of the common code - The irq pending work is canceled properly at free / shutdown While we're at it, changed the bit field flag to bool, as the bit field doesn't help much in our case.

ALSA: hda: Avoid quirk matching with zero PCI SSID

2026-05-16T13:45:02+00:00

Heiko reported that BIOS on some recent machines doesn't set up PCI SSID properly but leave with zero (e.g. on HP Dragonfly Folio 13.5 inch G3 with SSID 103c:8a05/8a06), which confuses the quirk table matching and results in the non-functional state. Fix it by skipping the PCI SSID matching when either vendor or device ID is zero and falling back to the codec SSID that is supposed to be more stable for those cases.

ALSA: hda: Fix NULL pointer dereference in snd_hda_ctl_add()

2026-05-15T07:09:07+00:00

snd_hda_ctl_add() dereferences kctl->id.subdevice without checking whether kctl is NULL. Multiple callers in sound/hda/codecs/ca0132.c pass the return value of snd_ctl_new1() directly to snd_hda_ctl_add() without a NULL check: return snd_hda_ctl_add(codec, nid, snd_ctl_new1(&knew, codec)); snd_ctl_new1() returns NULL when the underlying snd_ctl_new() fails on memory allocation (kzalloc_flex),which can occur under memory pressure or via fault injection. Add a NULL check at the entry of snd_hda_ctl_add(), matching the pattern already used by snd_ctl_add_replace() at the same call path (sound/core/control.c:515). Return -EINVAL to let callers handle the error gracefully.
