ALSA: firewire-tascam: fix corruption due to spin lock without restoration in SoftIRQ context

2020-01-13T09:41:01+00:00

ALSA firewire-tascam driver can bring corruption due to spin lock without restoration of IRQ flag in SoftIRQ context. This commit fixes the bug.

ALSA: firewire: Drop superfluous ioctl PCM ops

2019-12-11T06:25:27+00:00

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

2019-12-11T06:24:59+00:00

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: firewire: Convert to the common vmalloc memalloc

2019-11-06T14:47:42+00:00

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: postpone to start IR context

2019-10-19T07:18:27+00:00

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

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: firewire-tascam: share PCM buffer size for both direction

2019-10-18T02:35:50+00:00

This commit allows ALSA firewire-tascam 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

2019-10-18T02:35:40+00:00

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.
