* libavutil: Detect MMI and MSA flags for MIPSJiaxun Yang2020-07-23
| | | | | | | | | | | | | | | Add MMI & MSA runtime detection for MIPS. Basically there are two code pathes. For systems that natively support CPUCFG instruction or kernel emulated that instruction, we'll sense this feature from HWCAP and report the flags according to values grab from CPUCFG. For systems that have no CPUCFG (or not export it in HWCAP), we'll parse /proc/cpuinfo instead.

| * avutil: fix data race in av_get_cpu_flags()Wan-Teh Chang2016-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the one-time initialization in av_get_cpu_flags() thread-safe. The static variables |flags|, |cpuflags_mask|, and |checked| in libavutil/cpu.c are read and written using normal load and store operations. These are considered as data races. The fix is to use atomic load and store operations. Remove the |checked| variable because the invalid value of -1 for |flags| can be used to indicate the same condition. Rename |flags| to |cpu_flags| and move it to file scope. The fix can be verified by running the libavutil/tests/cpu_init.c test program under ThreadSanitizer: ./configure --toolchain=clang-tsan make libavutil/tests/cpu_init libavutil/tests/cpu_init There should be no warnings from ThreadSanitizer.

| * arm: add a cpu flag for the VFPv2 vector modeJanne Grunau2015-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The vector mode was deprecated in ARMv7-A/VFPv3 and various cpu implementations do not support it in hardware. Vector mode code will depending the OS either be emulated in software or result in an illegal instruction on cpus which does not support it. This was not really problem in practice since NEON implementations of the same functions are preferred. It will however become a problem for checkasm which tests every cpu flag separately. Since this is a cpu feature newer cpu do not support anymore the behaviour of this flag differs from the other flags. It can be only activated by runtime cpu feature selection.
