From e199eb5131591c020705deceee224b437d09ece4 Mon Sep 17 00:00:00 2001 From: Kan Liang Date: Wed, 30 Jun 2021 14:08:28 -0700 Subject: [PATCH] perf/x86/intel/uncore: Add Sapphire Rapids server IRP support The IRP is responsible for maintaining coherency for the IIO traffic targeting coherent memory. The layout of the control registers for a IRP uncore unit is a little bit different from the generic one. Factor out SPR_UNCORE_COMMON_FORMAT, which can be reused by the following uncore units.
