[PATCH v6 5/7] perf test: Add pmu-event test for "Compat" and new event_field.

From: Jing Zhang
Date: Mon Aug 07 2023 - 03:52:48 EST


Add new event test for uncore system event which is used to verify the
functionality of "Compat" matching multiple identifiers and the new event
fields "EventIdCode" and "Type".
