Subject: [PATCH v1 10/13] perf build: Switch libpfm4 to opt-out rather than opt-in
Date: Fri, 10 Mar 2023 22:57:50 -0800 [thread overview]
Message-ID: <20230311065753.3012826-11-irogers@google.com> (raw)
In-Reply-To: <20230311065753.3012826-1-irogers@google.com>
If libpfm4 passes the feature test, it would be nice to have it
enabled rather than also requiring the LIBPFM4=1 build flag.
