[PATCH v3 0/2] perf test: Add event group test

[Ravi Bangoria]

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@xxxxxxx
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.
