LIBPFM(3) Linux Programmer's Manual LIBPFM(3)NAMElibpfm_amd64_fam10h - support for AMD64 Family 10h processorsSYNOPSIS#include <perfmon/pfmlib.h> PMU name: amd64_fam10h_barcelona, amd64_fam10h_shanghai, amd64_fam10h_istanbul PMU desc: AMD64 Fam10h Barcelona, AMD64 Fam10h Shanghai, AMD64 Fam10h IstanbulDESCRIPTIONThe library supports AMD Family 10h processors in both 32 and 64-bit modes. They correspond to processor family 16.MODIFIERSThe following modifiers are supported on AMD64 Family 10h (16) 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. h Measure at while executing in host mode (when using virtualization). This corresponds to PFM_PLMH. This modifier is available starting with Fam10h. This is a boolean modifier. g Measure at while executing in guest mode (when using virtualization). This modifier is available starting with Fam10h. 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. 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> Robert Richter <robert.richter@amd.com> August, 2010 LIBPFM(3)
