NAME         top

       libpfm_amd64_fam15h - support for AMD64 Family 15h processors

SYNOPSIS         top

       #include <perfmon/pfmlib.h>
       PMU name: amd64_fam15h_interlagos
       PMU desc: AMD64 Fam15h Interlagos
       PMU name: amd64_fam15h_nb
       PMU desc: AMD64 Fam15h Northbridge

DESCRIPTION         top

       The library supports AMD Family 15h processors core PMU in both 32
       and 64-bit modes. The uncore (NorthBridge) PMU is also supported as a
       separate PMU model.

MODIFIERS         top

       The following modifiers are supported on AMD64 Family 15h core PMU:
       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
              occurrences of the event is greater or equal to the threshold.
              This is an integer modifier with values in the range [0:255].
       The uncore (NorthBridge) PMU does not support any modifiers.
