Описание (Description)
The library supports the Intel Skylake X Server UPI uncore PMU.
Модификаторы (Modifiers)
The following modifiers are supported on Intel Skylake X server
UPI 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 QPI 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].
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
BASIC_HDR_MATCH events
The library also supports the special RXL_BASIC_HDR_MATCH and
TXL_BASIC_HDR_MATCH opcode matcher events. These events have a
lot more filters available in the form of either a modifier
(listed below) or specific umasks. The following modifiers are
available in additional to the standard listed above:
rcsnid Specify a RCS Node identifier as an integer in the range
[0-15]. Default: 0
dnid Specify a destination Node identifier as an integer in the
range [0-15]. Default: 0
