From 5b26af6d2b7854639ddf893366bbca7e74fa7c54 Mon Sep 17 00:00:00 2001 From: Ravi Bangoria Date: Wed, 28 Sep 2022 15:27:56 +0530 Subject: [PATCH] perf/x86/amd: Support PERF_SAMPLE_PHY_ADDR IBS_DC_PHYSADDR provides the physical data address for the tagged load/ store operation. Populate perf sample physical address using it.
