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.

A generic transfer function will be created. Put together
functions related to it.

It is not needed.
As the pcm structure is opaque to user it can be safely
removed.

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.

pcm_mmap_transfer() will be rewritten. Put together
functions related to mmap transfer.

Use pcm_avail_update(), check avail for timestamp
coherence.

pcm_get_htimestamp() will be rewritten. Place it after
pcm_avail_update(), which will be used in the rewrite.

Instead of sending appl_ptr and avail_min to the kernel,
get them. This is the behavior of alsa-lib.

When hardware pointer update is requested and status
structure is mmaped, call HWSYNC ioctl.

Hardware pointer should not be updated in available
calculation.

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.

appl_ptr becomes zero in prepare action. avail_min is the
same as when it was set in software parameters.

Prepare is done in pcm_open().

Start is done by kernel when start_threshold or more frames
are requested.

The state cannot be assumed as RUNNING after a write
because start_threshold may not have elapsed.

This eliminates the need for prepare in transfer functions
and pcm_start().

meson: extract project version from header file and version .so
|
|
- Extract project version from tinyalsa/version.h for
easier maintainability
- Version shared lib: tinyalsa.so -> tinyalsa.so.1.1.1
|
|
Add support for Meson as build system
|
|
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.
