Subject: [PATCH 16/24] perf: Flag whether gtrace AUX data carries CoreSight framing
Date: Fri, 23 Oct 2026 11:14:57 +0800 [thread overview]
Message-ID: <20261023031505.2020925-17-liangzhen@linux.spacemit.com> (raw)
In-Reply-To: <20261023031505.2020925-1-liangzhen@linux.spacemit.com>
Define PERF_AUX_FLAG_GTRACE_FORMAT_CORESIGHT for the gtrace format
which reports whether the data has been wrapped in CoreSight frame
formatting by a CoreSight sink.
