Power9 DD1 do not support PMU_HAS_SIER flag and sdsync in perf_get_data_addr() defaults to MMCRA_SDSYNC which is wrong. Since power9 MMCRA does not support SDSYNC bit, patch includes PPMU_NO_SIAR flag to the check and set the sdsync with MMCRA_SAMPLE_ENABLE; Fixes: 27593d72c4ad ("powerpc/perf: Use MSR to report privilege level on P9 DD1") Signed-off-by: Madhavan Srinivasan Signed-off-by: Michael Ellerman Signed-off-by: Greg Kroah-Hartman --- arch/powerpc/perf/core-book3s.c | 2 ++ 1 file changed, 2 insertions(+) --- a/arch/powerpc/perf/core-book3s.c +++ b/arch/powerpc/perf/core-book3s.c @@ -183,6 +183,8 @@ static inline void perf_get_data_addr(st sdsync = POWER7P_MMCRA_SDAR_VALID; else if (ppmu->flags & PPMU_ALT_SIPR) sdsync = POWER6_MMCRA_SDSYNC; + else if (ppmu->flags & PPMU_NO_SIAR) + sdsync = MMCRA_SAMPLE_ENABLE; else sdsync = MMCRA_SDSYNC; Patches currently in stable-queue which might be from maddy@linux.vnet.ibm.com are queue-4.10/powerpc-perf-handle-sdar_mode-for-marked-event-in-power9.patch queue-4.10/powerpc-perf-avoid-fab_-_match-checks-for-power9.patch queue-4.10/powerpc-perf-fix-perf_get_data_addr-for-power9-dd1.patch
