Имя (Name)
libpfm_intel_core - support for Intel Core-based processors
Синопсис (Synopsis)
#include <perfmon/pfmlib.h>
PMU name: core
PMU desc: Intel Core
Описание (Description)
The library supports all Intel Core-based processors that
includes models 15, 23, 29.
Модификаторы (Modifiers)
The following modifiers are supported on Intel Core 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.
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 from no occurrence of the event to at
least one occurrence. This modifier must be combined with
a counter mask modifier (m) with a value greater or equal
to one. 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].
