17 (AXI filtering) fields of the perf_event_attr structure, see /sys/bus/event_source/
19 hardware supported that can be used with perf tool, see /sys/bus/event_source/
21 in DDR PMU, see /sys/bus/events_source/devices/imx8_ddr0/caps/.

25         perf stat -a -e imx8_ddr0/cycles/ cmd
26         perf stat -a -e imx8_ddr0/read/,imx8_ddr0/write/ cmd
28 AXI filtering is only used by CSV modes 0x41 (axid-read) and 0x42 (axid-write)
32 indicates whether PMU supports AXI ID filter or not; enhanced_filter indicates
33 whether PMU supports enhanced AXI ID filter or not. Value 0 for un-supported, and
38   --AXI_ID defines AxID matching value.
39   --AXI_MASKING defines which bits of AxID are meaningful for the matching.
41       - 0: corresponding bit is masked.
42       - 1: corresponding bit is not masked, i.e. used to do the matching.
45   When non-masked bits are matching corresponding AXI_ID bits then counter is
50   This filter doesn't support filter different AXI ID for axid-read and axid-write
