ALSA: firewire: Drop superfluous ioctl PCM ops

2019-12-11T06:25:27Z

All the PCM ioctl ops of ALSA FireWire drivers do nothing but calling the default handler. Now PCM core accepts NULL as the default ioctl ops(*), so let's drop altogether.

ALSA: firewire: Use managed buffer allocation

2019-12-11T06:24:59Z

Clean up the drivers with the new managed buffer allocation API. The superfluous snd_pcm_lib_malloc_pages() and snd_pcm_lib_free_pages() calls are dropped. Acked-by: Takashi Sakamoto Link: https://lore.kernel.org/r/20191209192422.23902-1-tiwai@suse.de Signed-off-by: Takashi Iwai

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

2019-12-09T19:06:18Z

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

ALSA: firewire: Convert to the common vmalloc memalloc

2019-11-06T14:47:42Z

The recent change (*) in the ALSA memalloc core allows us to drop the special vmalloc-specific allocation and page handling. This patch coverts to the common code.

ALSA: firewire-lib: replace ack callback to flush isoc contexts in AMDTP domain

2019-10-19T07:18:22Z

An isoc context for AMDTP stream is flushed to queue packet by a call of pcm.ack. This commit extends this for AMDTP domain. Signed-off-by: Takashi Sakamoto Link: https://lore.kernel.org/r/20191018061911.24909-4-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: fireface: use the same size of period for PCM substreams in AMDTP streams

2019-10-17T10:02:47Z

In current implementation, when opening a PCM substream, it's needed to check whether the opposite PCM substream runs. This is to assign effectual constraints (e.g. sampling rate) to opened PCM substream. The number of PCM substreams on AMDTP streams in domain is recorded in own structure. Usage of this count is an alternative of the above check. This is better because the count is incremented in pcm.hw_params earlier than pcm.trigger. This commit replaces the check with the substream count and the value for the size of PCM period. Unlike the other drivers in ALSA firewire stack, no MIDI substream is multiplexed into AMDTP stream. I note that Fireface AMDTP protocol has a quirk that tx stream includes blank isochronous cycle. The packet for blank cycle is equivalent to empty or NODATA packet in IEC 61883-6, thus the protocol is similar to blocking transmission method of IEC 61883-6. On the other hand, rx stream adopts non-blocking transmission method. Although the difference of transmission method between tx/rx streams precisely brings different timing for a certain amount of events due to their different calculation for data blocks per packet, it's possible to approximate enough amount of events mostly has the same timing. Actually current ALSA IEC 61883-1/6 engine uses large amount of data blocks for each hardware IRQ (=16 packets).

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.
