libpfm_intel_snbep_unc_imc - support for Intel Sandy Bridge-EP Inte‐
grated Memory Controller (IMC) uncore PMU
#include <perfmon/pfmlib.h>
PMU name: snbep_unc_imc[0-3]
PMU desc: Intel Sandy Bridge-EP IMC uncore PMU
The library supports the Intel Sandy Bridge Integrated Memory
Controller (IMC) uncore PMU. This PMU model only exists on Sandy
Bridge model 45. There are four IMC PMUs per socket.
The following modifiers are supported on Intel Sandy Bridge C-Box
uncore PMU:
i Invert the meaning of the event. The counter will now count
IMC 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 threshold
modifier (t) with a value greater or equal to one. This is a
boolean modifier.
t Set the threshold value. When set to a non-zero value, the
counter counts the number of IMC 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].
