Subject: [PATCH v1 09/10] perf: Add build id and filename to perf_brstack/ip_srcline
Date: Thu, 5 Sep 2024 08:08:03 -0700 [thread overview]
Message-ID: <20240905151058.2127122-10-ak@linux.intel.com> (raw)
In-Reply-To: <20240905151058.2127122-1-ak@linux.intel.com>
Add the buildid and executable file name to the tuple returned by the
new perf_brstack/ip_srcline python callbacks. This is all useful for
some analysis by perf scripts.
