24x7 counters can belong to different domains (core, chip, virtual CPU etc). For events in the 'chip' domain, sysfs entry currently looks like: $ cd /sys/bus/event_source/devices/hv_24x7/events $ cat PM_XLINK_CYCLES__PHYS_CHIP domain=0x1,offset=0x230,core=?,lpar=0x0 where the required parameter, 'core=?' is specified with perf as: perf stat -C 0 -e hv_24x7/PM_XLINK_CYCLES__PHYS_CHIP,core=1/ \ /bin/true This is inconsistent in that 'core' is a required parameter for a chip event. Instead, have the the sysfs entry display 'chip=?' for chip events: $ cd /sys/bus/event_source/devices/hv_24x7/events $ cat PM_XLINK_CYCLES__PHYS_CHIP domain=0x1,offset=0x230,chip=?,lpar=0x0 We also need to add a 'chip' entry in the sysfs format directory: $ ls /sys/bus/event_source/devices/hv_24x7/format chip core domain lpar offset vcpu ^^^^ (new) so the perf tool can automatically check usage and format the chip parameter correctly: $ perf stat -C 0 -v -e hv_24x7/PM_XLINK_CYCLES__PHYS_CHIP/ \ /bin/true Required parameter 'chip' not specified invalid or unsupported event: 'hv_24x7/PM_XLINK_CYCLES__PHYS_CHIP/' $ perf stat -C 0 -v -e hv_24x7/PM_XLINK_CYCLES__PHYS_CHIP,chip=1/ \ /bin/true hv_24x7/PM_XLINK_CYCLES__PHYS_CHIP,chip=1/: 0 6628908 6628908 Performance counter stats for 'CPU(s) 0': 0 hv_24x7/PM_XLINK_CYCLES__PHYS_CHIP,chip=1/ 0.006606970 seconds time elapsed Signed-off-by: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> |
