Load up the non volatile FPU and VMX regs and ensure that they are the expected value in a signal handler Signed-off-by: Cyril Bur <cyrilbur@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>	2016-03-02 23:34:47 +11:00
Cyril Bur	e5ab8be68e	selftests/powerpc: Test preservation of FPU and VMX regs across preemption ... Loop in assembly checking the registers with many threads. Signed-off-by: Cyril Bur <cyrilbur@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>	2016-03-02 23:34:47 +11:00
Cyril Bur	01127f1ead	selftests/powerpc: Test the preservation of FPU and VMX regs across syscall ... Test that the non volatile floating point and Altivec registers get correctly preserved across the fork() syscall. fork() works nicely for this purpose, the registers should be the same for both parent and child Signed-off-by: Cyril Bur <cyrilbur@gmail.com> [mpe: Add include guards to basic_asm.h, minor formatting] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>	2016-03-02 23:34:46 +11:00
