fixed_counter Struct Reference

Structure containing configuration data for each fixed-function performance counter as encoded in IA32_PERF_GLOBAL_CTL and IA32_FIXED_CTR_CTL. More...

#include <msr_counters.h>

Public Attributes
uint64_t *	enable
	Raw value stored in enable bit field of IA32_PERF_GLOBAL_CTL, indicating availability of fixed-function performance counter.
uint64_t *	ring_level
	Raw value stored in enable bit field of IA32_FIXED_CTR_CTL, enabling counting of events occurring in the specified ring level (i.e., none, OS, user, both).
uint64_t *	anyThread
	Raw value stored in AnyThread bit field of IA32_FIXED_CTR_CTL enables all threads sharing the same processor thread (hyperthreaded scenario) to increment the counter.
uint64_t *	pmi
	Raw value stored in performance monitoring interrupt (PMI) enable bit field of AI32_FIXED_CTR_CTL, allowing logical processor to generate an exception when the counter overflows.
uint64_t **	value
	Raw 64-bit value stored in IA32_FIXED_CTR[0-3].
uint64_t *	overflow

Detailed Description

Structure containing configuration data for each fixed-function performance counter as encoded in IA32_PERF_GLOBAL_CTL and IA32_FIXED_CTR_CTL.

Member Data Documentation

uint64_t* fixed_counter::anyThread

Raw value stored in AnyThread bit field of IA32_FIXED_CTR_CTL enables all threads sharing the same processor thread (hyperthreaded scenario) to increment the counter.

uint64_t* fixed_counter::enable

Raw value stored in enable bit field of IA32_PERF_GLOBAL_CTL, indicating availability of fixed-function performance counter.

uint64_t* fixed_counter::overflow
