Описание (Description)
The library supports the Intel Skylake X server system
configuration unit (U-Box) uncore PMU.
Модификаторы (Modifiers)
The following modifiers are supported on Intel Skylake X server
U-Box 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 [0:15].
i Invert the meaning of the threshold or edge filter. If
set, the event counts when strictly less than N
occurrences occur per cycle if threshold is set to N. When
invert is set, then threshold must be set to non-zero
value. If set, the event counts when the event transitions
from occurring to not occurring (falling edge) when edge
detection is set. This is a boolean modifier
