전체 글 (30) 썸네일형 리스트형 Offcore Response Event Event number 0B7H support offcore response monitoring using an associated configuration MSR, MSR_OFFCORE_RSP0 (address 1A6H) in conjunction with umask value 01H or MSR_OFFCORE_RSP1 (address 1A7H) in conjunction with umask value 02H. Table 18-14 lists the event code, mask value and additional off-core configuration MSR that must be programmed to count off-core response events using IA32_PMCx. The.. Hyperthreading OFF cat /sys/devices/system/cpu/smt/active echo on > /sys/devices/system/cpu/smt/control echo off > /sys/devices/system/cpu/smt/control Intel PMU There are a finite number of performance event select MSRs (IA32_PERFEVTSELx MSRs). The result of a performance monitoring event is reported in a performance monitoring counter (IA32_PMCx MSR). 두 register는 아래의 사항을 따른다. IA32_PERFEVTSELx의 bit field layout은 모든 microarchitecture들이 동일하다. IA32_PERFEVTSELx MSRs의 주소와 IA32_PMC MSRs의 주소는 모든 microarchitecture들이 동일하다. 모든 logical processor는 IA32_PERFEVTSELx .. 이전 1 2 3 4 5 ··· 10 다음
