Subject: [PATCH v4 8/9] perf c2c: Support AUX trace
Date: Fri, 6 Nov 2020 17:48:52 +0800 [thread overview]
Message-ID: <20201106094853.21082-9-leo.yan@linaro.org> (raw)
In-Reply-To: <20201106094853.21082-1-leo.yan@linaro.org>
This patch adds the AUX callbacks in session structure, so support
AUX trace for "perf c2c" tool; make itrace memory event as default for
"perf c2c", this tells the AUX trace decoder to synthesize samples and
can be used for statistics.
