2020-02-07tinyalsa: add support for PCM pluginsBhalchandra Gajare
Update the pcm framework to support plugins. Resolve the pcm device node to be either kernel device or virtual device and setup function pointers accordingly. Implement framework functionality for pcm_plugin.c for ease of plugin development. Plugin itself is compiled as shared object (.so) and dynamically linked from pcm_plugin.c.

This allows starting capture from another thread. See the commit 932a81519572 ("ALSA: pcm: Comment why read blocks when PCM is not running") in Linux kernel. Signed-off-by: Ricardo Biehl Pasquali <pasqualirb@gmail.com>

Changed order of operations to preserve the precision during the division.
2019-04-11Move changelog check ver. from build systems to CIAlexandru N. Onea
This commit moves the changelog version check to the CI instead of the build systems. Rationale is: the failure to update the changelog is not a build failure / issue but rather an integration failure and it should be detected at integration testing. The closest to integration testing is the CI testing which is mandatory before pull requests and new features integration. Additionally, the old version.py script is removed because it is relying on the old version of include/tinyalsa/version.h where the TINYALSA_VERSION_STRING macro is defiend as an explicit string literal. Since now the version string is defined piece-wise and based on the individual version numbers, and since the introduction of version.sh and its use within meson build system to get the version from the version file, the old version.py script is obsolete.

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>

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>

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>
