Subject: [PATCH v3 06/15] perf/x86/amd: Support PERF_SAMPLE_PHY_ADDR
Date: Wed, 28 Sep 2022 15:27:56 +0530 [thread overview]
Message-ID: <20220928095805.596-7-ravi.bangoria@amd.com> (raw)
In-Reply-To: <20220928095805.596-1-ravi.bangoria@amd.com>
IBS_DC_PHYSADDR provides the physical data address for the tagged load/
store operation. Populate perf sample physical address using it.
