Синопсис (Synopsis)
#include <perfmon/pfmlib.h>
PMU name: snbep_unc_r3qpi0, snbep_unc_r3qpi0
PMU desc: Intel Sandy Bridge-EP R3QPI uncore PMU
Описание (Description)
The library supports the Intel Sandy Bridge R3QPI uncore PMU.
This PMU model only exists on Sandy Bridge model 45. There are
two R3QPI PMUs per processor socket.
Модификаторы (Modifiers)
The following modifiers are supported on Intel Sandy Bridge R3PQI
uncore PMU:
i Invert the meaning of the event. The counter will now
count R3QPI 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 R3QPI 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 [0:15].
