[alsa-devel] [RFCv3][PATCH 00/39] axfer: rewrite aplay, adding 'timer-based scheduling' option

[Takashi Sakamoto]

Hi,

This 3rd RFC patchset updates my previous one:
[alsa-devel] [RFCv2][PATCH 00/38] alsa-utils: axfer: rewrite aplay
http://mailman.alsa-project.org/pipermail/alsa-devel/2017-September/125574.html

For aim of this rewrite and its intension, please refer to my former posts.

In this version, I add an option to support 'timer-based scheduling' scenario,
which PulseAudio developers introduced. Please refer to patch 32:
 * axfer: add support for timer-based MMAP operation

You can use this mode by adding '-sched-type=timer' option into command
line.

The other difference from my previous one:
 - fix some bugs to handle non-interleaved buffer on mapped page frame.
 - use snd_pcm_status() instead of snd_pcm_state() to execute hwsync.
 - minor fixes.

In my plan, this is the last version including below patches. In next post,
options added by below patches are categorized as obsoleted:
 * axfer: add an option to support volume unit meter
 * axfer: add a unit test for vumeter calculation
 * axfer: add an option for formatted filename
 * axfer: add an option to handle key events
 * axfer: add a parser for channel map API
 * axfer: add a feature to generate a file for process id

Additionally, for next post, I'll prepare for help messages and man for this
program.

Regards
