libpfm_intel_icx_unc_ubox - support for Intel IcelakeX Server UBOX
uncore PMU
#include <perfmon/pfmlib.h>
PMU name: icx_unc_ubox
PMU desc: Intel IcelakeX UBOX uncore PMU
The library supports the Intel IcelakeX UBOX (System configuration
controller) uncore PMU. There is one UBOX per processor. Each UBOX PMU
implements 4 generic counters.
The following modifiers are supported on Intel IcelakeX UBOX
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 UBOX clockticks 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.
