It also adds some architectural MSRs for PEBS. A similar patch for i386 will follow. changelog: - add Intel Precise-Event Based sampling (PEBS) related MSR - add Intel Data Save (DS) Area related MSR - add Intel Core microarchitecure performance counter MSRs Signed-off-by: stephane eranian Signed-off-by: Andi Kleen --- diff --git a/include/asm-x86_64/msr.h b/include/asm-x86_64/msr.h index 37e194169fac..a745c5008a60 100644 --- a/include/asm-x86_64/msr.h +++ b/include/asm-x86_64/msr.h @@ -210,6 +210,10 @@ static inline unsigned int cpuid_edx(unsigned int op) #define MSR_IA32_LASTINTFROMIP 0x1dd #define MSR_IA32_LASTINTTOIP 0x1de +#define MSR_IA32_PEBS_ENABLE 0x3f1 +#define MSR_IA32_DS_AREA 0x600 +#define MSR_IA32_PERF_CAPABILITIES 0x345 + #define MSR_MTRRfix64K_00000 0x250 #define MSR_MTRRfix16K_80000 0x258 #define MSR_MTRRfix16K_A0000 0x259 @@ -407,4 +411,13 @@ static inline unsigned int cpuid_edx(unsigned int op) #define MSR_P4_U2L_ESCR0 0x3b0 #define MSR_P4_U2L_ESCR1 0x3b1 +/* Intel Core-based CPU performance counters */ +#define MSR_CORE_PERF_FIXED_CTR0 0x309 +#define MSR_CORE_PERF_FIXED_CTR1 0x30a +#define MSR_CORE_PERF_FIXED_CTR2 0x30b +#define MSR_CORE_PERF_FIXED_CTR_CTRL 0x38d +#define MSR_CORE_PERF_GLOBAL_STATUS 0x38e +#define MSR_CORE_PERF_GLOBAL_CTRL 0x38f +#define MSR_CORE_PERF_GLOBAL_OVF_CTRL 0x390 + #endif
