This may not be a desirable since # "perf" API is the primary interface to program PMU and # collect counter data in the system. But that said, we # cant remove these sysfs files since we dont whether # anyone/anything is using them. # # So the patch adds a new CONFIG option 'CONFIG_PMU_SYSFS' # (user selectable) to be used in sysfs file creation for # PMU SPRs. New option by default is disabled, but can be # enabled if user needs it. # # Tested this patch behaviour in powernv and pseries machines. # Patch is also tested for pmac32_defconfig. # #
