Описание (Description)
The library supports the Intel Ivy Bridge Home Agent (HA) uncore
PMU. This PMU model only exists on Ivy Bridge model 62.
Модификаторы (Modifiers)
The following modifiers are supported on Intel Ivy Bridge HA
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 HA 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].
