Subject: [PATCH v4 20/35] perf evsel: Compute is_hybrid from PMU being core
Date: Fri, 26 May 2023 14:53:55 -0700	[thread overview]
Message-ID: <20230526215410.2435674-21-irogers@google.com> (raw)
In-Reply-To: <20230526215410.2435674-1-irogers@google.com>

Short-cut when has_hybrid is false, otherwise return if the evsel's
PMU is core. Add a comment for the some what surprising no PMU cases
of hardware and legacy cache events.
