Add sysfs format entries for AMD IBS PMUs: # find /sys/bus/event_source/devices/ibs_*/format /sys/bus/event_source/devices/ibs_fetch/format /sys/bus/event_source/devices/ibs_fetch/format/rand_en /sys/bus/event_source/devices/ibs_op/format /sys/bus/event_source/devices/ibs_op/format/cnt_ctl This allows to specify following IBS options: $ perf record -e ibs_fetch/rand_en=1/GH ... $ perf record -e ibs_op/cnt_ctl=1/GH ... Option cnt_ctl is only enabled if the IBS_CAPS_OPCNT bit is set in IBS cpuid feature flags (AMD family 10h RevC and above).
