ALSA: core: fix up bus match const issues.

2025-06-19T13:31:33+00:00

[ Upstream commit 62f134ab190c5fd5c9f68fe638ad8e13bb8a4cb4 ] In commit d69d80484598 ("driver core: have match() callback in struct bus_type take a const *"), the match bus callback was changed to have the driver be a const pointer. Unfortunately that const attribute was thrown away when container_of() is called, which is not correct and was not caught by the compiler due to how container_of() is implemented. Fix this up by correctly preserving the const attribute of the driver passed to the bus match function which requires the hdac_driver match function to also take a const pointer for the driver structure.

ALSA: hda: fix trigger_tstamp_latched

2024-10-02T10:50:24+00:00

When the trigger_tstamp_latched flag is set, the PCM core code assumes that the low-level driver handles the trigger timestamping itself. Ensure that runtime->trigger_tstamp is always updated.

ALSA: hda: Introduce flags to force commands via PIO instead of CORB

2024-04-18T06:38:54+00:00

Add AZX_DCAPS_PIO_COMMANDS quirk (bit 31) and use_pio_for_commands flag to be able to select PIO mode as alternative for CORB based command sending while retaining the RIRB functionality to receive unsolicited responses. This mode differs from the azx single_cmd mode when RIRB is disabled. The mixed mode is needed on Lunar Lake family because it is recommended to use Immediate Command Response (PIO mode) instead of CORB for HDA commands.

ALSA: mark all struct bus_type as const

2023-12-30T09:10:41+00:00

Now that the driver core can properly handle constant struct bus_type, move all of the sound subsystem struct bus_type structures as const, placing them into read-only memory which can not be modified at runtime. Note, this fixes a duplicate definition of ac97_bus_type, which somehow was declared extern in a .h file, and then static as a prototype in a .c file, and then properly later on in the same .c file. Amazing that no compiler warning ever showed up for this. Cc: Jaroslav Kysela Cc: Takashi Iwai Cc: Dawei Li Cc: Yu Liao Cc: "Rafael J.

ALSA: hda: Upgrade stream-format infrastructure

2023-11-27T16:27:41+00:00

Introduce a set of functions that ultimately facilite SDxFMT-related calculations in atomic manner: First, introduce snd_pcm_subformat_width() and snd_pcm_hw_params_bits() helpers that separate the base functionality from the HDAudio-specific one. snd_hdac_format_normalize() - format converter. S20_LE, S24_LE and their unsigned and BE friends are invalid from HDAudio perspective but still can be specified as function argument due to compatibility reasons. snd_hdac_stream_format_bits() - obtain just the bits-per-sample value. Does not ignore subformat and msbits parameters. snd_hdac_stream_format() and snd_hdac_spdif_stream_format() - obtain the SDxFMT value given the audio format parameters. The former is stripped away of spdif-related information. Useful for users that do not care about them.

ALSA: hda: Honor subformat when querying PCMs

2023-11-27T16:24:27+00:00

Update mechanism for querying supported PCMs to allow for granular format selection when container size is 32 bits. Currently always the highest bit depth is selected, regardless of how many actual formats codec in question supports.
