ALSA: speakers: Rename to oxfw and rename some members

2014-11-29T19:21:15+00:00

This commit renames 'firewire-speakers' to 'oxfw' to enhance support for devices which based on OXFW970/971. A line for MODULE_ALIAS is added. Additionally, to help for works in followed paches, some members in private structure are renamed. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: firewire-lib: Add some AV/C general commands

2014-05-26T12:23:13+00:00

This commit adds three commands, which may be used by some firewire device drivers. These commands are defined in 'AV/C Digital Interface Command Set General Specification Version 4.2 (2004006, 1394TA)'. 1. PLUG INFO command (clause 10.1) 2. INPUT PLUG SIGNAL FORMAT command (clause 10.10) 3. OUTPUT PLUG SIGNAL FORMAT command (clause 10.11) By the command 1, the drivers can get the number of plugs for AV/C unit or subunit. By the command 2 and 3, the drivers can get/set sampling frequency. The 'firewire-speakers' already uses INPUT PLUG SIGNAL FORMAT command to set sampling rate. So this commit also affects the driver.

ALSA: firewire-lib: Add 'direction' member to 'cmp_connection' structure

2014-05-26T12:22:14+00:00

This patch adds 'direction' member to 'cmp_connection' structure to indicate the direction of connection. This patch also adds 'direction' argument to cmp_connection_init() function to determine the direction. The cmp_connection_init() function is exported and used in snd-firewire-speakers so this patch also affect it. This patch just add them. Actual implementation will be done by followed patches.

ALSA: firewire-lib/dice/speakers: Add common PCM constraints for AMDTP streams

2014-05-26T12:21:46+00:00

This commit adds common PCM constraints according to current firewire-lib implementation. 1.Maximum width for each sample is limited by 24. AM824 in IEC 61883-6 can deliver 24bit data. 2. Minimum time for period is 5msec. Apply the old value. For shorter latency, further works are needed. 3. In blocking mode, frames per period/buffer is aligned to 32. Each packet can include some frames depending on its sampling rate. In blocking mode, the number equals to SYT_INTERVAL. Currently firewire-lib can schedule snd_pcm_period_elapsed() for each packet. So, for accurate PCM interrupt, the number of frames per period/buffer should be aligned to SYT_INTERVAL. Currently firewire-lib is lack of better rules to achieve this. So LCM of each value of SYT_INTERVALs (=32) is applied. This can be improved for further work.

ALSA: firewire-lib: Add 'direction' member to 'amdtp_stream' structure

2014-05-26T12:11:42+00:00

This patch adds 'direction' member to amdtp_stream structure to indicate its direction. This patch also adds 'direction' argument to amdtp_stream_init() function to determine its direction. The amdtp_stream_init() function is exported and used by firewire-speakers and dice so this patch also affects them. This patch just add them. Actual implementation will be done by followed patches.

ALSA: firewire-lib: Rename functions, structure, member for AMDTP

2014-05-26T12:11:10+00:00

This patch renames some functions, a structure and its member to reuse them in both AMDTP in/out stream. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: firewire: Convert to snd_card_new() with a device pointer

2014-02-14T07:13:31+00:00

Also remove superfluous snd_card_set_dev() calls. Reviewed-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: firewire: extend snd_fw_transaction()

2013-10-20T20:07:57+00:00

Add a flag to snd_fw_transaction() to allow it to abort when a bus reset happens. This removes most of the duplicated error handling loops that were required around calls to the low-level fw_run_transaction(). Also add a flag to suppress error messages; errors are expected when we attempt to clean up after the device was unplugged. Signed-off-by: Clemens Ladisch

ALSA: dice: support dual-wire stream format at 192 kHz

2013-10-20T20:07:57+00:00

Change the AMDTP streaming code to handle the non-standard stream format that DICE devices use at sample rates greater than 96 kHz. Signed-off-by: Clemens Ladisch
