All of the mentioned commits are in v4.6 and later, thus this is fix released in yakkety and zesty.

Currently the event is specified to the perf tool as: 'hv_24x7/HPM_0THRD_NON_IDLE_CCYC__PHYS_CORE,core=1/' \ where the event name is 'HPM_0THRD_NON_IDLE_CCYC', the suffix '__PHYS_CORE' specifies the domain, and 'core=1' specifies the core. This is inconsistent in that one parameter is specified as a suffix and the other in a parameter=value format. To simplify the usage, we can eliminate the suffix and let the user specify the domain also in the param=value format. While the domain indices are "well known" or nearly fixed in value, we could display the domain indices in sysfs as a reference for the users: $ cat /sys/bus/event_source/devices/hv_24x7/interface/domains 1: Physical Chip 2: Physical Core 3: VCPU Home Core 4: VCPU Home Chip 5: VCPU Home Node 6: VCPU Remote Node Using these the perf event can now be identified as hv_24x7/HPM_0THRD_NON_IDLE_CCYC,domain=2,core=1 . This feature is implemented by the following commits which have now been merged into mainline: d34171e: powerpc/perf/hv-24x7: Display domain indices in sysfs 8f69dc7: powerpc/perf/24x7: Eliminate domain suffix in event names == Comment: #1 - Sukadev Bhattiprolu <s...@us.ibm.com> - 2016-03-21 15:26:33 == Following two upstream commits are also related 24x7 and could be included in this feature: e5a5886: powerpc/perf/hv-24x7: Fix usage with chip events. 2b206ee: powerpc/perf/hv-24x7: Display change in counter values To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1560482/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
