Clemens Ladisch	5b2599a07e	ALSA: firewire-lib: allocate DMA buffer separately ... For correct cache coherency on some architectures, DMA buffers must be allocated in a different cache line than data that is concurrently used by the CPU.

Clemens Ladisch	be45436632	ALSA: firewire-lib: use no-info SYT for packets without SYT sample ... In non-blocking mode, the SYT_INTERVAL is larger than the number of audio frames in each packet, so there are packets that do not contain any frame to which the SYT could be applied. For these packets, the SYT must not be the timestamp of the next valid SYT frame, but the special no-info SYT value. This fixes broken playback on the FireWave at 44.1 kHz.

Clemens Ladisch	31ef9134eb	ALSA: add LaCie FireWire Speakers/Griffin FireWave Surround driver ... Add a driver for two playback-only FireWire devices based on the OXFW970 chip. v2: better AMDTP API abstraction; fix fw_unit leak; small fixes v3: cache the iPCR value v4: FireWave constraints; fix fw_device reference counting; fix PCR caching; small changes and fixes v5: volume/mute support; fix crashing due to pcm stop races v6: fix build; one-channel volume for LaCie v7: use signed values to make volume (range checks) work; fix function block IDs for volume/mute; always use channel 0 for LaCie volume Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Acked-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Tested-by: Jay Fenlason <fenlason@redhat.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>	2011-03-15 08:42:22 +01:00
