From dde994dd54fbf84f8fd14230de3477d552e42470 Mon Sep 17 00:00:00 2001 From: Kim Phillips Date: Tue, 17 Aug 2021 17:15:08 -0500 Subject: [PATCH] perf report: Add tools/arch/x86/include/asm/amd-ibs.h This is a tools/-side patch for the patch that adds the original copy of the IBS header file, in arch/x86/include/asm/. We also add an entry to check-headers.sh, so future changes continue to be copied. Committer notes: Had to add this -#include +#include "msr-index.h" And change the check-headers.sh entry to ignore this line when diffing with the original kernel header. This is needed so that we can use 'perf report' on a perf.data with IBS data on a !x86 system, i.e. building on ARM fails without this as there is no asm/msr-index.h there. This was done on the next patch in this series and is done for things like Intel PT and ARM CoreSight.
