LIBPFM(3) Linux Programmer's Manual LIBPFM(3)NAMElibpfm_intel_core - support for Intel Core-based processorsSYNOPSIS#include <perfmon/pfmlib.h> PMU name: core PMU desc: Intel CoreDESCRIPTIONThe library supports all Intel Core-based processors that includes models 15, 23, 29.MODIFIERSThe following modifiers are supported on Intel Core processors: u Measure at user level which includes privilege levels 1, 2, 3. This corresponds to PFM_PLM3. This is a boolean modifier. k Measure at kernel level which includes privilege level 0. This corresponds to PFM_PLM0. This is a boolean modifier. i Invert the meaning of the event. The counter will now count cycles in which the event is not occurring. This is a boolean modifier e Enable edge detection, i.e., count only when there is a state transition from no occurrence of the event to at least one occurrence. This modifier must be combined with a counter mask modifier (m) with a value greater or equal to one. This is a boolean modifier. c Set the counter mask value. The mask acts as a threshold. The counter will count the number of cycles in which the number of occur- rences of the event is greater or equal to the threshold. This is an integer modifier with values in the range [0:255].AUTHORSStephane Eranian <eranian@gmail.com> September, 2009 LIBPFM(3)
