Subject: [PATCH V2 14/23] perf record: Use evlist__add_dummy_on_all_cpus() in record__config_text_poke()
Date: Fri,  6 May 2022 15:25:52 +0300	[thread overview]
Message-ID: <20220506122601.367589-15-adrian.hunter@intel.com> (raw)
In-Reply-To: <20220506122601.367589-1-adrian.hunter@intel.com>

Use evlist__add_dummy_on_all_cpus() in record__config_text_poke() in
preparation for allowing system-wide events on all CPUs while the user
requested events are on only user requested CPUs.
