From 342e53bd8548e07c6a734d2d3a6437ad6e6d3b09 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 5 Oct 2018 13:28:07 +0100 Subject: arm64: perf: Add support for Armv8.1 PMCEID register format Armv8.1 allocated the upper 32-bits of the PMCEID registers to describe the common architectural and microarchitecture events beginning at 0x4000. Add support for these registers to our probing code, so that we can advertise the SPE events when they are supported by the CPU.
