From 451ed8058c69a3fee29fa9e2967a4e22a221fe75 Mon Sep 17 00:00:00 2001 From: Athira Rajeev Date: Fri, 20 May 2022 15:42:36 +0530 Subject: perf test: Fix "all PMU test" to skip hv_24x7/hv_gpci tests on powerpc "perf all PMU test" picks the input events from "perf list --raw-dump pmu" list and runs "perf stat -e" for each of the event in the list. In case of powerpc, the PowerVM environment supports events from hv_24x7 and hv_gpci PMU which is of example format like below: - hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/ - hv_gpci/event,partition_id=?/ The value for "?" needs to be filled in depending on system and respective event. CPM_ADJUNCT_INST needs have core value and domain value. hv_gpci event needs partition_id. Similarly, there are other events for hv_24x7 and hv_gpci having "?" in event format. Hence skip these events on powerpc platform since values like partition_id, domain is specific to system and event.
