ALSA: line6: Add hwdep interface to access the POD control messages

2016-09-19T21:03:47Z

We must do it this way, because e.g. POD X3 won't play any sound unless the host listens on the bulk EP, so we cannot export it only via libusb. The driver currently doesn't use the bulk EP messages in other way, in future it could e.g. sense/modify volume(s). Signed-off-by: Andrej Krutak Signed-off-by: Takashi Iwai

ALSA: timer: remove legacy rtctimer

2016-04-25T08:41:46Z

There are no users of rtctimer left. Remove its code as this is the in-kernel user of the legacy PC RTC driver that will hopefully be removed at some point. Signed-off-by: Alexandre Belloni Signed-off-by: Takashi Iwai

ALSA: uapi: Make alsa asound.h header more portable

2016-03-04T09:50:48Z

This header is used as-is in the alsa-lib userland library, which is portable to other operating systems. For this reason, include linux/types.h only on Linux systems. Add sys/ioctl.h for _IOR/_IOW/etc. (works at least on *BSD and Solaris). Signed-off-by: Thomas Klausner Signed-off-by: Takashi Iwai

ALSA: firewire-tascam: add hwdep interface

2015-10-02T16:17:04Z

This commit adds hwdep interface so as the other IEEE 1394 sound devices has. This interface is designed for mixer/control applications. By using this interface, an application can get information about firewire node, can lock/unlock kernel streaming and can get notification at starting/stopping kernel streaming.

ALSA: asound.h - use SNDRV_CTL_ELEM_ID_NAME_MAXLEN

2015-04-18T07:05:55Z

we have defined SNDRV_CTL_ELEM_ID_NAME_MAXLEN as size of name array so use this define instead of numeric value Signed-off-by: Vinod Koul Signed-off-by: Takashi Iwai

ALSA: bump PCM protocol to 2.0.13

2015-02-20T16:30:07Z

Bump PCM protocol to enable use of STATUS_EXT ioctls, older apps will still use STATUS and audio timestamp configuration is not supported (backwards compatible behavior). Signed-off-by: Pierre-Louis Bossart Signed-off-by: Takashi Iwai

ALSA: core: selection of audio_tstamp type and accuracy reports

2015-02-20T16:30:03Z

Audio timestamps can be extracted from sample counters, wall clocks, PHC clocks (Ethernet AVB), on-demand synchronized snapshots. This patch provides the ability to report timestamping capabilities, select timestamp types and retrieve timestamp accuracy, if supported. Details can be found in Documentations/sound/alsa/timestamping.txt This functionality is introduced by reclaiming the reserved_aligned field introduced by commit9c7066aef4a5eb8e4063de28f06c508bf6f2963a in snd_pcm_status to provide userspace with selection/query capabilities. Additional driver_tstamp and audio_tstamp_accuracy fields are also added. snd_pcm_mmap_status remains a read-only structure with only the audio timestamp value accessible from user space. The selection of audio timestamp type is done through snd_pcm_status only This commit does not impact ABI and does not impact the default behavior. By default audio timestamp is aligned with hw_pointer and reports the DMA position. Backwards compatibility is handled by using the HDAudio wall clock for playback and the hw_ptr for all other cases. For timestamp selection a new STATUS_EXT ioctl is introduced with read/write parameters. Alsa-lib will be modified to make use of STATUS_EXT.
