2020-06-05include/tinyalsa/plugin.h: include time.hEthan Sommer
Older versions of linux's API header sound/asound.h accidentally rely on indirect declaration of struct timespec, which isn't reliable, so include time.h before it to support older versions of sound/asound.h properly

Various cmake improvements
2020-06-04Various cmake improvementsEthan Sommer
Use scripts/version.sh, and set version in project() using its output. Instead of using a variable to store the definition of TINYALSA_USES_PLUGINS, and adding it as a compile option, use a generator expression to define it in target_compile_definitions when the option is enabled. Set BUILD_SHARED_LIBS to on by default. Add options to disable examples and utils. Instead of using SRCS and HDRS variables, set PUBLIC_HEADER property on tinyalsa to install the headers along with the target. Set library version, so the shared library will have version suffixes. Check that C warning flags are supported instead of adding them unconditionally. Use ${CMAKE_DL_LIBS} instead of hardcoding "dl", and add it to tinyalsa's link interface and link depends, instead of linking it in the examples and utils. Add the "include" directory as a PUBLIC include directory to tinyalsa, instead of making it PRIVATE and adding it to examples and utils as well, because anything linking the tinyalsa target will need to include "include". Instead of using macros for building examples and utils, use a for loop. Include cmake's GNUInstallDirs to automatically correctly populate installation dir variables, instead of doing it manually.

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.

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.

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.
