pcm: Remove setting unnecessary parameters
2019-04-12pcm: Remove setting unnecessary parametersRicardo Biehl Pasquali
SUBFORMAT is always zero. SAMPLE_BITS and FRAME_BITS are refined by ALSA based on the already set FORMAT and CHANNELS. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>

2019-01-08pcm: Check for error after setting appl_ptrRicardo Biehl Pasquali

2019-01-08pcm: Cleanup control/status when setup failsRicardo Biehl Pasquali

2019-01-08pcm: Replace 'underruns' with 'xruns'Ricardo Biehl Pasquali
Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Create generic transferRicardo Biehl Pasquali
Group read/write transfer into pcm_rw_transfer(). Create pcm_generic_transfer() for read/write and mmap transfer modes. This recovers from xrun and suspended. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Put transfer functions togetherRicardo Biehl Pasquali
A generic transfer function will be created. Put together functions related to it. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Remove 'running' variable from pcm structureRicardo Biehl Pasquali
It is not needed. As the pcm structure is opaque to user it can be safely removed. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Rewrite pcm_mmap_transfer() for compatibilityRicardo Biehl Pasquali
Make pcm_mmap_transfer() compatible with read/write IO. start_threshold check was not valid for capture. pcm->running checks were removed. NOIRQ fallback was removed. Clocks of sound devices may differ from the system, leading to desynchronization. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Exit loop when there are no available framesRicardo Biehl Pasquali
Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Put mmap functions togetherRicardo Biehl Pasquali
pcm_mmap_transfer() will be rewritten. Put together functions related to mmap transfer. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Add macro for PREPARED stateRicardo Biehl Pasquali
Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Rewrite pcm_get_htimestamp()Ricardo Biehl Pasquali
Use pcm_avail_update(), check avail for timestamp coherence. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Move pcm_get_htimestamp()Ricardo Biehl Pasquali
pcm_get_htimestamp() will be rewritten. Place it after pcm_avail_update(), which will be used in the rewrite. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Get values from kernel in avail_updateRicardo Biehl Pasquali
Instead of sending appl_ptr and avail_min to the kernel, get them. This is the behavior of alsa-lib. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Call HWSYNC ioctl when status is mmapedRicardo Biehl Pasquali
When hardware pointer update is requested and status structure is mmaped, call HWSYNC ioctl. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Remove HWSYNC before available calculationRicardo Biehl Pasquali
Hardware pointer should not be updated in available calculation. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Do not set values after control/status mmapRicardo Biehl Pasquali
It's not necessary to send appl_ptr or avail_min to the kernel here. In prepare action, called later in pcm_open(), appl_ptr becomes zero. avail_min is already defined in software parameters. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Get appl_ptr and avail_min after prepareRicardo Biehl Pasquali
appl_ptr becomes zero in prepare action. avail_min is the same as when it was set in software parameters. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Remove 'prepared' variable from pcm structureRicardo Biehl Pasquali
It is not needed. As the pcm structure is opaque to user it can be safely removed. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Remove prepare before startRicardo Biehl Pasquali
Prepare is done in pcm_open(). Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Remove start before readRicardo Biehl Pasquali
Start is done by kernel when start_threshold or more frames are requested. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Prepare after overrunRicardo Biehl Pasquali
Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Remove code assuming start after writeRicardo Biehl Pasquali
The state cannot be assumed as RUNNING after a write because start_threshold may not have elapsed. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Move prepare action to xrun handlingRicardo Biehl Pasquali
Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>
2019-01-08pcm: Do prepare action in pcm_open()Ricardo Biehl Pasquali
This eliminates the need for prepare in transfer functions and pcm_start(). Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>

Add support for Meson as build system
2018-12-15Add support for Meson as build systemTim-Philipp Müller
The Meson build system is being adopted by projects such as GNOME, PulseAudio, GStreamer, VLC, systemd, Mesa, Wayland, X.org, and many others. Having a meson build upstream in tinyalsa would allow for easy use of tinyalsa as a Meson subproject in other projects. https://mesonbuild.com
