Синопсис (Synopsis)

PMU name: bdx_unc_imc[0-7]
PMU desc: Intel Broadwell Server IMC uncore PMU
Описание (Description)
The library supports the Intel Broadwell Server Integrated Memory
Controller (IMC) uncore PMU. This PMU model only exists on
various Broadwell server models (79, 86).
Модификаторы (Modifiers)
The following modifiers are supported on Intel Broadwell server
IMC 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 IMC 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
