Subject: [PATCH v3 0/2] perf test: Add event group test
Date: Tue, 6 Dec 2022 10:02:35 +0530 [thread overview]
Message-ID: <20221206043237.12159-1-ravi.bangoria@amd.com> (raw)
Multiple events in a group can belong to one or more pmus, however
there are some limitations to it. One of the limitation is, perf
doesn't allow creating a group of events from different hw pmus.
Write a simple test to create various combinations of hw, sw and
uncore pmu events and verify group creation succeeds or fails as
expected.
v2: https://lore.kernel.org/r/20221129111946.409-1-ravi.bangoria@amd.com
v2->v3:
- Define a set of uncore pmus that supports more than 3 events. This
will prevent false negative results by not picking random uncore
pmu. Test will be skipped if no uncore pmu found.
