ALSA: aloop: Introduce a function to get if access is interleaved mode

2024-01-12T08:45:56+00:00

There's a use case that playback stream of a loopback cable works on
RW_INTERLEAVED mode while capture stream works on MMAP_INTERLEAVED mode:

aplay -Dhw:Loopback,0,0 S32_48K_2ch.wav;
arecord -Dplughw:Loopback,1,0 -fS32_LE -r16000 -c2 cap.wav;

The plug plugin handles only slave PCM support MMAP mode. Not only plug
plugin but also other plugins like direct plugins(dmix/dsnoop/dshare)
work on MMAP access mode. In this case capture stream is the slave
PCM works on MMAP_INTERLEAVED mode. However loopback_check_format()
rejects this access setting and return:

arecord: pcm_read:2240: read error: Input/output error

To fix it a function called is_access_interleaved() is introduced to
get if access is interleaved mode. If both access of capture stream and
playback stream is interleaved mode loopback_check_format() will allow
this kind of access setting.

tty: serdev: convert to u8 and size_t

2023-12-08T11:02:38+00:00

Switch character types to u8 and sizes to size_t. To conform to
characters/sizes in the rest of the tty layer.

This patch converts struct serdev_device_ops hooks and its
instantiations.

ALSA: pcmtest: stop timer before buffer is released

2023-12-07T07:33:06+00:00

Stop timer in the 'trigger' and 'sync_stop' callbacks since we want
the timer to be stopped before the DMA buffer is released. Otherwise,
it could trigger a kernel panic in some circumstances, for instance
when the DMA buffer is already released but the timer callback is
still running.

ALSA: aloop: Add control element for getting the access mode

2023-10-06T09:11:40+00:00

Add new control element 'PCM Slave Access Mode' which shows the access
mode (interleaved/non-interleaved) for the PCM playing device. Add
corresponding control change notification calls.

ALSA: aloop: Add support for the non-interleaved access mode

2023-10-06T09:11:40+00:00

The current version of the loopback driver supports interleaved access
mode only. This patch introduces support for the non-interleaved
access mode.

When in the interleaved mode, the 'copy_play_buf' function copies data
from the playback to the capture buffer using one memcpy call. This call
copies samples for multiple, interleaved channels.

In the non-interleaved mode we have multiple channel buffers, so we have
to perform multiple memcpy calls to copy samples channel after channel.

Add new function called 'copy_play_buf_part_n', which copies a part of
each channel buffer from playback to capture. Modify the 'copy_play_buf'
to use the corresponding memory copy function(just memcpy /
copy_play_buf_part_n) depending on the access mode.

Merge tag 'asoc-v6.6' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2023-08-28T14:13:03+00:00

ASoC: Updates for v6.6

The rest of the updates for v6.6, some of the highlights include:

 - A big API cleanup from Morimoto-san, rationalising the places we put
   functions.
 - Lots of work on the SOF framework, AMD and Intel drivers, including a
   lot of cleanup and new device support.
 - Standardisation of the presentation of jacks from drivers.
 - Provision of some generic sound card DT properties.
 - Conversion oof more drivers to the maple tree register cache.
 - New drivers for AMD Van Gogh, AWInic AW88261, Cirrus Logic cs42l43,
   various Intel platforms, Mediatek MT7986, RealTek RT1017 and StarFive
   JH7110.

ALSA: pcmtest: Add support for pcm pausing

2023-08-24T07:58:22+00:00

Add pause push/release support to the virtual PCM test driver. Add
'suspend' boolean field to the pcmtst_buf_iter structure, so we can
pause the timer without shutting it down. Update the trigger callback
handler correspondingly. Extract buffer initialization to the
'reset_buf_iterator' function since it is used in multiple places now.
