ALSA: fireface: fix return value in error path of isochronous resources reservation

2019-12-17T19:07:56+00:00

commit 480136343cbe89426d6c2ab74ffb4e3ee572c7ee upstream. Even if isochronous resources reservation fails, error code doesn't return in pcm.hw_params callback.

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.

Merge branch 'for-linus' into for-next

2019-07-01T15:01:55+00:00

This back-merge is necessary for adjusting the latest FireWire fix with the recent refactoring in 5.3 development branch. Signed-off-by: Takashi Iwai

ALSA: fireface: unify stop and release method for duplex streams

2019-06-21T09:47:00+00:00

>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: code refactoring for pcm.hw_params/hw_free callbacks

2019-06-11T09:36:27+00:00

The pairs of pcm.hw_params callbacks and .hw_free callbacks for both direction have no differences. This commit unifies the pairs. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: fireface: minor code refactoring to finish streaming session

2019-06-11T09:36:26+00:00

The operation to finish packet streaming corresponds to stopping isochronous contexts. This commit applies code refactoring to move codes to stop into a helper function to finish the session. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

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

2019-06-11T09:36:25+00:00

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

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

2019-06-11T09:36:24+00:00

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: support allocate_resources operation in latter protocol

2019-06-11T09:36:24+00:00

This commit is a part of preparation to perform allocation/release of isochronous channels in pcm.hw_params/hw_free callbacks. This commit implements allocate_resources callback for the protocol specific to latter models. The encoded values of constant table is split into several condition statements to separate the operation to configure sampling transfer frequency from the operation to configure the number of data channels in rx packet.

This commit is a part of preparation to perform allocation/release of isochronous channels in pcm.hw_params/hw_free callbacks. This commit implements allocate_resources callback for ff400 protocol. In this callback, sampling transfer frequency is configured to the device as well. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai
