Integrated Memory Controller (IMC) uncore PMU
Синопсис (Synopsis)
#include <perfmon/pfmlib.h>
PMU name: snbep_unc_imc[0-3]
PMU desc: Intel Sandy Bridge-EP IMC uncore PMU
Описание (Description)
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.
Модификаторы (Modifiers)
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].
