Replace by more specific (headers)

2026-07-03T05:38:16+00:00

is included in a many files: $ git grep '' ef0c9f75a195 | wc -l 1598 ; some of them are widely used headers. To stop mixing up different and unrelated driver( type)s let the subsystem headers only use the subset of the recently split that are relevant for them. The fallout (I hope) is addressed in the previous commits that handle sources relying on e.g. pulling in the full legacy header and thus providing pci_device_id.

ALSA: hda: Force resume if acomp notified during system suspend

2026-06-29T10:38:48+00:00

Currently if an HDMI cable is connected while the system is suspended, the HDMI audio jack status stays off after resume. This is due to the jack state not being synced by the HDA HDMI codec device's runtime resume, as that never happens if the device was runtime suspended before the system suspended, or by the acomp notification triggered from the DRM side if that happens before the HDA HDMI codec device has resumed. To fix this, if snd_hda_hdmi_acomp_pin_eld_notify() gets called before the HDA HDMI codec device has resumed, mark it to be forcefully runtime resumed at the next PM complete time. Do this using a separate acomp_requested_resume flag that can be temporarily set without overwriting forced_resume for drivers that always want to force resume.

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

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: Add a simple GPIO setup helper function

2026-04-09T10:05:54+00:00

Introduce a common GPIO setup helper function, so that we can clean up the open code found in many codec drivers later. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20260409093826.1317626-3-tiwai@suse.de

ALSA: hda: Add sync version of snd_hda_codec_write()

2026-04-09T10:05:54+00:00

We used snd_hda_codec_read() for the verb write when a synchronization is needed after the write, e.g. for the power state toggle or such cases. It works in principle, but it looks rather confusing and too hackish. For improving the code readability, introduce a new helper function, snd_hda_codec_write_sync(), which is another variant of snd_hda_codec_write(), and replace the existing snd_hda_codec_read() calls with this one. No behavior change but just the code refactoring. Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20260409093826.1317626-2-tiwai@suse.de

ALSA: hda: Introduce auto cleanup macros for PM

2025-08-29T09:52:13+00:00

The temporary power up/down of the codec via snd_hda_power_up() and _down() (or snd_hda_power_up_pm() and _down_pm()) is seen in various places. This patch introduces simple auto-cleanup macros for those call patterns, so that the drivers don't have to call the corresponding power-down calls explicitly. Namely, err = snd_hda_power_up(codec); if (err < 0) return err; .... snd_power_down(codec); can drop the *_down() call by replacing with CLASS(snd_hda_power, pm)(codec); if (pm.err < 0) return pm.err; Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250827072916.31933-2-tiwai@suse.de

ALSA: hda: Use min() to simplify snd_hda_get_devices()

2025-08-14T06:39:54+00:00

Use min() to simplify snd_hda_get_devices() and improve its readability. Change the function parameter 'max_devices' from 'int' to 'unsigned int' to avoid a min() signedness error. Update all related local variables and the function's return type to 'unsigned int' accordingly. No functional changes intended.

ALSA: hda: Drop old codec binding method

2025-07-11T07:55:38+00:00

Now that all patch_ops usage have been converted to the new hda_codec_ops probe, we can drop patch_ops from the hda_codec, together with the calls of patch_ops callbacks. The hda_codec_ops.free callback is removed as all have been replaced with the new remove callback. Also, correct comments mentioning "patch"; it's replaced with "codec driver".
