Subject: [PATCH 1/5] perf record: Always get text_poke events with --kcore option
Date: Fri, 10 Jun 2022 14:33:12 +0300 [thread overview]
Message-ID: <20220610113316.6682-2-adrian.hunter@intel.com> (raw)
In-Reply-To: <20220610113316.6682-1-adrian.hunter@intel.com>
kcore provides a copy of the running kernel including any modified code.
A trace that benefits from that also benefits from text_poke events, so
enable them.
