From c1f4f92b7d5d3deeaae758a1a7ed263b1381dd1c Mon Sep 17 00:00:00 2001 From: Ravi Bangoria Date: Sat, 4 Jun 2022 10:15:18 +0530 Subject: perf tool ibs: Sync AMD IBS header file IBS support has been enhanced with two new features in upcoming uarch: 1. DataSrc extension 2. L3 miss filtering. Additional set of bits has been introduced in IBS registers to exploit these features. New bits are already defining in arch/x86/ header. Sync it with tools header file. Also rename existing ibs_op_data field 'data_src' to 'data_src_lo'.
