Subject: [PATCH 09/13] perf scripting python: Add perf_set_itrace_options()
Date: Sun, 30 May 2021 22:23:04 +0300 [thread overview]
Message-ID: <20210530192308.7382-10-adrian.hunter@intel.com> (raw)
In-Reply-To: <20210530192308.7382-1-adrian.hunter@intel.com>
Add perf_set_itrace_options() to the perf_trace_context module so that a
script can set the itrace options for a session if they have not been set
already.
