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: Move controller drivers into sound/hda/controllers directory

2025-07-11T07:55:37+00:00

Now HD-audio controller drivers are moved into sound/hda/controllers directory as a part of HD-audio code reorganization. Most of drivers are independent from PCI bus, hence it makes more sense to put under sound/hda. The hda_ prefix is dropped from most of files at moving, as it's more or less superfluous.
