libpfm_intel_icx_unc_imc - support for Intel Icelake X Server
Integrated Memory Controller (IMC) uncore PMU
#include <perfmon/pfmlib.h>
PMU name: icx_unc_imc[0-11]
PMU desc: Intel Icelake X Server IMC uncore PMU
The library supports the Intel Icelake X Server Integrated Memory
Controller (IMC) uncore PMU.
The following modifiers are supported on Intel Icelake X server
IMC 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]. i Invert the threshold (t) test from
strictly greater than to less or equal to. This is a boolean
modifier.
