Описание (Description)
The library supports the Intel Ivy Bridge R3QPI uncore PMU. This
PMU model only exists on Ivy Bridge model 62.
Модификаторы (Modifiers)
The following modifiers are supported on Intel Ivy Bridge R3PQI
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 R3QPI 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 [0:15].
