H A D | vsx_asm.S | 65ca668f Fri Sep 23 01:18:13 CDT 2016 Cyril Bur <cyrilbur@gmail.com> selftests/powerpc: Check for VSX preservation across userspace preemption
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.
