ALSA: isight: adjust for new queueing API

2011-06-17T09:37:29Z

Since commit 13882a82ee16 (optimize iso queueing by setting wake only after the last packet), drivers are required to call fw_iso_context_queue_flush() after queueing a batch of packets. The missing call would have an effect only if the controller queue underruns, but then the DMA would stop completely. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: isight: fix locking

2011-05-11T12:53:09Z

Lockdep complains about conflicts between isight->mutex, ALSA's register_mutex, mm->mmap_sem, and pcm->open_mutex. This can be fixed by moving the calls to isight_pcm_abort(), snd_card_disconnect(), and fw_iso_resources_update() out of isight->mutex. These functions are designed to be called asynchronously; the mutex needs to protect only the device streaming state modified by isight_start/stop_streaming().

ALSA: isight: fix hang when unplugging a running device

2011-05-11T12:53:08Z

When aborting a PCM stream, the xrun is signaled only if the stream is running. When disconnecting a PCM stream, calling snd_card_disconnect() too early would change the stream into a non-running state and thus prevent the xrun from being noticed by user space. To prevent this, move the snd_card_disconnect() call after the xrun. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: isight: fix divide error when queueing packets

2011-05-11T12:51:16Z

Set the .header_size field when queueing packets to avoid a division by zero. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: isight: fix packet requeueing

2011-05-11T12:51:13Z

After handling a received packet, we want to resubmit the same packet, so do not increase the packet index too early. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: isight: fix isight_pcm_abort() crashes

2011-05-11T12:51:09Z

Fix crashes in isight_pcm_abort() that happen when the driver tries to access isight->pcm->runtime which does not exist when the device is not open. Introduce a new field pcm_active to track this state. Signed-off-by: Clemens Ladisch Reported-by: Stefan Richter Signed-off-by: Takashi Iwai
