NAME¶
libpfm_intel_ivbep_unc_imc - support for Intel Ivy Bridge-EP Integrated Memory
Controller (IMC) uncore PMU
SYNOPSIS¶
#include <perfmon/pfmlib.h>
PMU name: ivbep_unc_imc[0-7]
PMU desc: Intel Ivy Bridge-EP IMC uncore PMU
DESCRIPTION¶
The library supports the Intel Ivy Bridge Integrated Memory Controller (IMC)
uncore PMU. This PMU model only exists on Ivy Bridge model 62.
MODIFIERS¶
The following modifiers are supported on Intel Ivy Bridge C-Box uncore PMU:
- 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].
