Subject: [RFC PATCH v9 7/7] perf test: Add test for Intel TPEBS counting mode
Date: Tue, 21 May 2024 13:39:35 -0400 [thread overview]
Message-ID: <20240521173952.3397644-8-weilin.wang@intel.com> (raw)
In-Reply-To: <20240521173952.3397644-1-weilin.wang@intel.com>
From: Weilin Wang <weilin.wang@intel.com>
Intel TPEBS sampling mode is supported through perf record. The counting mode
code uses perf record to capture retire_latency value and use it in metric
calculation. This test checks the counting mode code.
Signed-off-by: Weilin Wang <weilin.wang@intel.com>
