Incase of # event codes using PMC5 and PMC6 ( 500fa and 600f4 respectively ), not # all constraints are applicable, say the threshold or sample bits. But # current code includes pmc5 and pmc6 in some group constraints (like # IC_DC Qualifier bits) which is actually not applicable and hence # results in those events not getting counted when scheduled along with # group of other events. Patch fixes this by excluding PMC5/6 from # constraints which are not relevant for it. # # Fixes: 7ffd948 ("powerpc/perf: factor out power8 pmu functions") # Signed-off-by: Athira Rajeev # Reviewed-by: Madhavan Srinivasan #
