ALSA: firewire-lib: postpone to start IR context

2019-10-19T07:18:27Z

Some devices have a quirk to postpone transmission of isoc packet for several dozen or hundred isoc cycles since configured to transmit. Furthermore, some devices have a quirk to transmit isoc packet with discontinued data of its header. In 1394 OHCI specification, software allows to start isoc context with certain isoc cycle. Linux firewire subsystem has kernel API to use it as well. This commit uses the functionality of 1394 OHCI controller to handle the quirks. At present, this feature is convenient to ALSA bebob and fireface driver. As a result, some devices can be safely handled, as long as I know: - MAudio FireWire solo - MAudio ProFire Lightbridge - MAudio FireWire 410 - Roland FA-66 Signed-off-by: Takashi Sakamoto Link: https://lore.kernel.org/r/20191018061911.24909-7-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai

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: firewire-lib: use variable size of queue for isoc packets instead of fixed size

2019-10-18T02:35:40Z

The number of packets in packet buffer has been fixed number (=48) since first commit of ALSA IEC 61883-1/6 packet streaming engine. This commit allows the engine to use variable number of packets in the buffer. The size is calculated by a parameter in AMDTP domain structure surely to store the number of events in the packets of buffer. Although the value of parameter is expected to come from 'period size' parameter of PCM substream, at present 48 is still used.

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: update isochronous resources when starting packet streaming after bus-reset

2019-06-11T09:36:25Z

After bus reset, isochronous resource manager releases all of allocated isochronous resources. The nodes to restart packet streaming should request reallocation of the resources. However, between the bus-reset and invocation of 'struct fw_driver.update' handler, ALSA PCM application can detect this situation by XRUN because the target device cancelled to transmit packets once bus-reset occurs. Due to the above mechanism, ALSA fireface driver just stops packet streaming in the update handler, thus pcm.prepare handler should request the reallocation. This commit requests the reallocation in pcm.prepare callback when bus generation is changed. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai
