linux-toradex.git/tools/testing/selftests/powerpc/math/vsx_asm.S, branch v4.9.80 Linux kernel for Apalis and Colibri modules selftests/powerpc: Check for VSX preservation across userspace preemption 2016-10-04T09:10:09+00:00 Cyril Bur cyrilbur@gmail.com 2016-09-23T06:18:13+00:00 65ca668f58a260e144621fd93a413da67635b999 Ensure the kernel correctly switches VSX registers correctly. VSX registers are all volatile, and despite the kernel preserving VSX across syscalls, it doesn't have to. Test that during interrupts and timeslices ending the VSX regs remain the same.
