From 9a3b675cd393a4430d5e6cbf94c5de43414613cd Mon Sep 17 00:00:00 2001 From: Alexander Antonov Date: Thu, 17 Nov 2022 12:28:31 +0000 Subject: [PATCH] perf/x86/intel/uncore: Enable UPI topology discovery for Sapphire Rapids UPI topology discovery on SPR is same as in ICX but UBOX device has different Device ID 0x3250. This patch enables /sys/devices/uncore_upi_*/die* attributes on SPR.
