.SH DESCRIPTION
Packit
577717
The library supports the Intel Broadwell Server Integrated Memory Controller (IMC) uncore PMU.
Packit
577717
This PMU model only exists on various Broadwell server models (79, 86).

.SH MODIFIERS
Packit
577717
The following modifiers are supported on Intel Broadwell server IMC uncore PMU:
Packit
577717
.TP
Packit
577717
.B e
Packit
577717
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.
Packit
577717
.TP
Packit
577717
.B t
Packit
577717
Set the threshold value. When set to a non-zero value, the counter counts the number
Packit
577717
of IMC cycles in which the number of occurrences of the event is greater or equal to
Packit
577717
the threshold. This is an integer modifier with values in the range [0:255].
Packit
577717
.B i
Packit
577717
Invert the meaning of the threshold or edge filter. If set, the event counts when strictly less
Packit
577717
than N occurrences occur per cycle if threshold is set to N. When invert is set, then threshold
Packit
577717
must be set to non-zero value. If set, the event counts when the event transitions from occurring
Packit
577717
to not occurring (falling edge) when edge detection is set. This is a boolean modifier
