sukadev@linux.vnet.ibm.com e6878835ac powerpc/perf: Sample only if SIAR-Valid bit is set in P7+ ... powerpc/perf: Sample only if SIAR-Valid bit is set in P7+ On POWER7+ two new bits (mmcra[35] and mmcra[36]) indicate whether the contents of SIAR and SDAR are valid. For marked instructions on P7+, we must save the contents of SIAR and SDAR registers only if these new bits are set. This code/check for the SIAR-Valid bit is specific to P7+, so rather than waste a CPU-feature bit use the PVR flag. Note that Carl Love proposed a similar change for oprofile: https://lkml.org/lkml/2012/6/22/309 Signed-off-by: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>		2012-09-27 12:51:05 +10:00
