From 77fad8bfb1d2f8225b05e4ea34457875fcfae37e Mon Sep 17 00:00:00 2001 From: Gustavo Romero Date: Wed, 1 Nov 2017 15:23:41 -0400 Subject: selftests/powerpc: Check FP/VEC on exception in TM Add a self test to check if FP/VEC/VSX registers are sane (restored correctly) after a FP/VEC/VSX unavailable exception is caught during a transaction. This test checks all possibilities in a thread regarding the combination of MSR.[FP|VEC] states in a thread and for each scenario raises a FP/VEC/VSX unavailable exception in transactional state, verifying if vs0 and vs32 registers, which are representatives of FP/VEC/VSX reg sets, are not corrupted.
