2021-06-12T07:33:09+00:00

All of devices with Echo Audio Fireworks board module has the same combination of specifier_id (0x00a02d) and version (0x010000) in unit directory. Signed-off-by: Takashi Sakamoto Link: https://lore.kernel.org/r/20210611093730.78254-3-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai

ALSA: fireworks: cease from delayed card registration

2021-06-07T15:13:29+00:00

The delayed registration of sound card instance brings less benefit than complication of kobject management. This commit ceases from it. Signed-off-by: Takashi Sakamoto Link: https://lore.kernel.org/r/20210607081250.13397-3-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai

ALSA: fireworks: delete SYTMATCH clock source

2021-06-01T06:18:18+00:00

In the design of Fireworks board module, the device does't adjust its media clock voluntarily by the sequence of presentation time expressed in syt field of CIP header of received packet.

ALSA: fireworks: Replace zero-length array with flexible-array

2020-05-08T07:41:30+00:00

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

ALSA: fireworks: share PCM buffer size for both direction

2019-10-18T02:35:44+00:00

This commit allows ALSA fireworks driver to share PCM buffer size for both capture and playback PCM substream. When AMDTP domain starts for one of the PCM substream, buffer size of the PCM substream is stores to AMDTP domain structure. Some AMDTP streams have already run with the buffer size when another PCM substream starts, therefore the PCM substream has a constraint to its buffer size.

ALSA: fireworks: register the size of PCM period to AMDTP domain

2019-10-17T10:02:41+00:00

This commit is a preparation to share the size of PCM period between PCM substreams on AMDTP streams in the same domain. At this time, the size of PCM period in PCM substream which starts AMDTP streams in the same domain is recorded.

Merge tag 'asoc-v5.3' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2019-07-08T12:45:34+00:00

ASoC: Updates for v5.3 This is a very big update, mainly thanks to Morimoto-san's refactoring work and some fairly large new drivers. - Lots more work on moving towards a component based framework from Morimoto-san. - Support for force disconnecting muxes from Jerome Brunet. - New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90, Conexant CX2072X, Realtek RT1011 and RT1308.

ALSA: fireworks: configure sampling transfer frequency in pcm.hw_params callback

2019-06-12T13:26:52+00:00

This commit is a part of preparation to perform allocation/release of isochronous resources in pcm.hw_params/hw_free callbacks. At present, several operations are done in pcm.prepare callback. To reduce load of the callback, This commit splits out an operation to set sampling transfer frequency in pcm.hw_params callback. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: fireworks: unify substream counter

2019-06-12T13:26:49+00:00

This commit is a part of preparation to perform allocation/release of isochronous resources in pcm.hw_params/hw_free callbacks. It's inconvenient to handle two isochronous context separately each other. This commit unifies the counters to handle the two at the same time.
