Overview
The library supports the Intel Icelake X Server Mesh to Memory (M2M) uncore PMU.
Modifiers
The following modifiers are supported on Intel Icelake X server M2M 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 M2M 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].
iInvert the threshold (t) test from strictly greater than to less or equal to. This is a boolean modifier.
