2020-06-02mixer: Fix memory leak and other issues in mixer eventRohit kumar
Fix memory leak in mixer_wait_event(). Also, poll should be unblocked after increasing event_cnt in mixer_plugin, otherwise event_cnt can become negative during read_event. Fix the same.
2020-06-02mixer: Add plugin support for mixer_consume/read_eventRohit kumar
snd_ctl_event is needed by client to get details of event received. Introduce mixer_read_event() with plugin support to support this.
2020-06-02tinyalsa: add mixer_consume_eventAndrew Chant
mixer_consume_event consumes subscribed events from the mixer in order to allow monitoring of mixer control value changed.
2020-05-24src/pcm.c: remove MAP_FILE mmap flagEthan Sommer
MAP_FILE is a non-standard mmap flag, and has no effect on conformant systems.
2020-05-22scripts/version.sh: switch from bash to POSIX shEthan Sommer
Change shebang to #!/bin/sh. Remove usage of non-POSIX 'local' builtin, and replace it with using a function's positional parameters to store variables, as they are local to the function.

tinyalsa: use strncpy instead of memcpy to copy string constant
2020-04-24tinyalsa: mixer_plugin: remove dummy strings for sound cardMinecrell
There does not really seem to be an usage for these dummy string, so let's remove them.
2020-04-23tinyalsa: use strncpy instead of memcpy to copy string constantMinecrell
memcpy() is arguably wrong when copying these string constants. The string constants will usually just be as long as necessary, so we might copy some random memory behind it and eventually crash. Use strncpy() instead to avoid copying characters after the null terminator. For some reason the strings in snd_ctl_card_info use unsigned chars, so we need a cast to char* to make it compile unfortunately... This fixes the following compile error on ppc64le: In function 'mixer_plug_get_card_info', inlined from 'mixer_plug_ioctl' at mixer_plugin.c:371:15: mixer_plugin.c:333:5: error: 'memcpy' forming offset [9, 16] is out of the bounds [0, 8] [-Werror=array-bounds] 333 | memcpy(card_info->id, "card_id", sizeof(card_info->id)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Not sure why that warning does not exist on other architectures.

Plugin support
2020-02-07tinyalsa: add support for mixer pluginsBhalchandra Gajare
Update the mixer framework to support plugins. Add ability for physical card to have either kernel registered mixer controls or plugin registered mixer control or both. Split mixer controls into two groups, one for kernel registered (hw_grp) and the other for plugin registered (virtual_grp).

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.

pcm: Set SW params.avail_min to period size
2020-02-06pcm: Set SW params.avail_min to period sizeMiguel GAIO
Using MMAP APIs, this parameter wake up application when 'avail_min' samples are availables. When audio processing expects exactly a full period size samples, the default parameter to 1 burns CPU until the full period available. Fix SW params.avail parameter to period size value.
