From: Kan Liang Date: Tue, 26 May 2015 13:10:35 +0000 (-0400) Subject: perf/x86/intel/uncore: Fix CBOX bit wide and UBOX reg on Haswell-EP X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8cf1a3de97804b047973dd44cfacdc1930da8403;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git perf/x86/intel/uncore: Fix CBOX bit wide and UBOX reg on Haswell-EP CBOX counters are increased to 48b on HSX. Correct the MSR address for HSWEP_U_MSR_PMON_CTR0 and HSWEP_U_MSR_PMON_CTL0.
