b7df4cc3 - ALSA: misc: Use -y instead of -objs in Makefile

Tue, 07 May 2024 13:55:09 +0000

ALSA: misc: Use *-y instead of *-objs in Makefile*-objs suffix is reserved rather for (user-space) host programs whileusually *-y suffix is used for kernel drivers (although *-objs worksfor that purpose for now).Let's correct the old usages of *-objs in Makefiles.Signed-off-by: Takashi Iwai Reviewed-by: Andy Shevchenko Reviewed-by: Jaroslav Kysela Link: https://lore.kernel.org/r/20240507135513.14919-10-tiwai@suse.de List of files: /linux-6.15/sound/virtio/Makefile

d6568e3d - ALSA: virtio: add support for audio controls

Mon, 15 Jan 2024 13:36:54 +0000

ALSA: virtio: add support for audio controlsImplementation of support for audio controls in accordance with theextension of the virtio sound device specification [1] planned forvirtio-v1.3-cs01.The device can announce the VIRTIO_SND_F_CTLS feature. If the feature isnegotiated, then an additional field appears in the configuration space: struct virtio_snd_config { ... /* number of available control elements */ __le32 controls; };The driver can send the following requests to manage audio controls: enum { ... /* control element request types */ VIRTIO_SND_R_CTL_INFO = 0x0300, VIRTIO_SND_R_CTL_ENUM_ITEMS, VIRTIO_SND_R_CTL_READ, VIRTIO_SND_R_CTL_WRITE, VIRTIO_SND_R_CTL_TLV_READ, VIRTIO_SND_R_CTL_TLV_WRITE, VIRTIO_SND_R_CTL_TLV_COMMAND, ... };And the device can send the following audio control event notification: enum { ... /* control element event types */ VIRTIO_SND_EVT_CTL_NOTIFY = 0x1200, ... };See additional details in [1].[1] https://lists.oasis-open.org/archives/virtio-comment/202104/msg00013.htmlSigned-off-by: Anton Yakovlev Signed-off-by: Aiswarya Cyriac Link: https://lore.kernel.org/r/20240115133654.576068-2-aiswarya.cyriac@opensynergy.comSigned-off-by: Takashi Iwai List of files: /linux-6.15/sound/virtio/Makefile

f40a2867 - ALSA: virtio: handling control and I/O messages for the PCM device

Tue, 02 Mar 2021 16:47:05 +0000

ALSA: virtio: handling control and I/O messages for the PCM deviceThe driver implements a message-based transport for I/O substreamoperations. Before the start of the substream, the hardware buffer issliced into I/O messages, the number of which is equal to the currentnumber of periods. The size of each message is equal to the currentsize of one period.I/O messages are organized in an ordered queue. The completion of theI/O message indicates an elapsed period (the only exception is the endof the stream for the capture substream). Upon completion, the messageis automatically re-added to the end of the queue.Signed-off-by: Anton Yakovlev Link: https://lore.kernel.org/r/20210302164709.3142702-6-anton.yakovlev@opensynergy.comSigned-off-by: Takashi Iwai List of files: /linux-6.15/sound/virtio/Makefile

ALSA: virtio: build PCM devices and substream hardware descriptorsLike the HDA specification, the virtio sound device specification linksPCM substreams, jacks and PCM channel maps into functional groups. Foreach discovered group, a PCM device is created, the number of whichcoincides with the group number.Introduce the module parameters for setting the hardware bufferparameters: pcm_buffer_ms [=160] pcm_periods_min [=2] pcm_periods_max [=16] pcm_period_ms_min [=10] pcm_period_ms_max [=80]Signed-off-by: Anton Yakovlev Link: https://lore.kernel.org/r/20210302164709.3142702-5-anton.yakovlev@opensynergy.comSigned-off-by: Takashi Iwai List of files: /linux-6.15/sound/virtio/Makefile

ALSA: virtio: handling control messagesThe control queue can be used by different parts of the driver to sendcommands to the device. Control messages can be either synchronous orasynchronous.
