Subject: perf test: Enable system wide for metricgroups test
From: Ian Rogers <irogers@xxxxxxxxxx>
commit 0046686da0ef692a6381260c3aa44291187eafc9 upstream.
Uncore events as group leaders fail in per-thread mode causing exit
errors. Enable system-wide for metricgroup testing. This fixes the HPC
metric group when tested on skylakex.
Fixes: 4a87dea9e60fe100 ("perf test: Workload test of metric and metricgroups")
