From 62e6eb8d5454401bc38b6eba35bab738b63a478b Mon Sep 17 00:00:00 2001 From: Leo Yan Date: Mon, 30 May 2022 16:36:45 +0800 Subject: [PATCH] perf mem: Trace physical address for Arm SPE events Currently, Arm SPE events don't trace physical address, therefore, the field 'phys_addr' is always zero in synthesized memory samples. This leads to perf c2c tool cannot locate the memory node for samples. This patch enables configuration 'pa_enable' for Arm SPE events, so the physical address packet can be traced, finally this can allow perf c2c tool to locate properly for memory node.
