linux/include/uapi/sound, branch v5.2

Merge tag 'asoc-fix-v5.2-rc4' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2019-06-13T15:33:34Z

ASoC: Fixes for v5.2 There's an awful lot of fixes here, almost all for the newly introduced SoF DSP drivers (including a few things it turned up in shared code). This is a large and complex piece of code so it's not surprising that there have been quite a few issues here, fortunately things seem to have mostly calmed down now. Otherwise there's just a smattering of small fixes.

ASoC: SOF: bump to ABI 3.6

2019-06-03T16:42:27Z

We had a couple of misses with ABI changes, e.g. for Xtensa oops information and the integration of sound trigger, before we set-up a formal process to track evolutions. With this patch, the SOF kernel patches are officially aligned with the firmware 3.6 level. Changing this level has no impact on existing users and is fully backwards-compatible.

ASoC: SOF: Add userspace ABI support

2019-04-27T17:49:18Z

Add userspace ABI for audio userspace application IO outside of regular ALSA PCM and kcontrols. This is intended to be used to format coefficients and data for custom processing components.

ALSA: uapi: #include in asound.h

2019-04-02T07:27:21Z

The uapi header asound.h defines types based on struct timespec. We need to #include to get access to the definition of this struct. Previously, we encountered the following error message when building applications with a clang/bionic toolchain: kernel-headers/sound/asound.h:350:19: error: field has incomplete type 'struct timespec' struct timespec trigger_tstamp; ^ The absence of the time.h #include statement does not cause build errors with glibc, because its version of stdlib.h indirectly includes time.h.

ALSA: firewire-tascam: notify events of change of state for userspace applications

2018-11-23T14:31:15Z

In former commits, ALSA firewire-tascam driver queues events to notify change of state of control surface to userspace via ALSA hwdep interface. This commit implements actual notification of the events. The events are not governed by real time, thus no need to care underrun. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: firewire-tascam: queue events for change of control surface

2018-11-23T14:31:12Z

Units of TASCAM FireWire series transfer image of states of the unit in tx isochronous packets. Demultiplexing of the states from the packets is done in software interrupt context regardless of any process context. In a view of userspace applications, it needs to have notification mechanism to catch change of the states. This commit implements a queue to store events for the notification. The image of states includes fluctuating data such as level of gain/volume for physical input/output and position of knobs. Therefore the events are queued corresponding to some control features only. Furthermore, the queued events are planned to be consumed by userspace applications via ALSA hwdep interface. This commit suppresses event queueing when no applications open the hwdep interface. However, the queue is maintained in an optimistic scenario, thus without any care against overrrun. This is reasonable because target events are useless just to handle PCM frames. It starts queueing when an usespace application opens hwdep interface, thus it's expected to read the queued events steadily. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: firewire-tascam: add new hwdep ioctl command to get state image

2018-11-23T14:31:10Z

In a previous commit, ALSA firewire-tascam driver stores state image from tx isochronous packets. This image includes states of knob, fader, button of control surface, level of gain/volume of each physical inputs/outputs, and so on. It's useful for userspace applications to read whole of the image. This commit adds a unique ioctl command for ALSA hwdep interface for the purpose. For actual meaning of each bits in this image, please refer to discussion in alsa-devel[1].

ALSA: firewire-tascam: pick up data of state from tx isochronous pakcets

2018-11-23T14:31:08Z

Units of TASCAM FireWire series multiplex PCM frames and state of control surface into the same tx isochronous packets. One isochronous packet includes a part of the state in a quadlet data. An image of the state consists of 64 quadlet data. This commit demultiplexes the state from tx isochronous packets. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai
