ALSA: fireface: share PCM buffer size for both direction

2019-10-18T02:35:52Z

This commit allows ALSA fireface 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: fireface: register the size of PCM period to AMDTP domain

2019-10-17T10:02:43Z

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

2019-07-08T12:45:34Z

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: fireface: unify stop and release method for duplex streams

>From callbacks for pcm and rawmidi interfaces, the functions to stop and release duplex streams are called at the same time. This commit merges the two functions. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: fireface: reserve/release isochronous resources in pcm.hw_params/hw_free callbacks

2019-06-11T09:36:24Z

Once allocated, isochronous resources are available for packet streaming, even if the streaming is cancelled. For this reason, current implementation handles allocation of the resources and starting packet streaming at the same time. However, this brings complicated procedure to start packet streaming. This commit separates the allocation and starting. The allocation is done in pcm.hw_params callback and available till pcm.hw_free callback. Even if any XRUN occurs, pcm.prepare callback is done to restart packet streaming for allocated the resources. There are two points to stop packet streaming; in pcm.hw_params and pcm.prepare callbacks. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: fireface: add protocol-specific operation to allocate isochronous resources

2019-06-11T09:36:22Z

This commit is a part of preparation to perform allocation/release of isochronous channels in pcm.hw_params/hw_free callbacks. In ALSA fireface driver, the allocation of isochronous resources is programmed in each implementation of protocol. This commit adds protocol-specific operation for the allocation separated from the operation to begin session. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: fireface: support rx MIDI functionality for Fireface UCX

2019-01-22T16:20:56Z

In latter model of Fireface series, asynchronous transaction includes a prefix byte to indicate the way to decode included MIDI bytes. Upper 4 bits of the prefix byte indicates port number, and the rest 4 bits indicate the way to decode rest of bytes for MIDI messages. Basically the rest bits indicates the number of bytes for MIDI message. However, if the last byte of each MIDi message is included, the rest bits are 0xf. For example: message: f0 00 00 66 14 20 00 00 f7 offset: content (big endian, port 0) '0030: 0x02f00000 '0030: 0x03006614 '0030: 0x03200000 '0030: 0x0ff70000 This commit supports encoding scheme for the above and allows applications to transfer MIDI messages via ALSA rawmidi interface. An unused member (running_status) is reused to keep state of transmission of system exclusive messages.
