.SH DESCRIPTION
Packit
577717
The library supports the Intel Sandy Bridge R3QPI uncore PMU.
Packit
577717
This PMU model only exists on Sandy Bridge model 45. There are
Packit
577717
two R3QPI PMUs per processor socket.

.SH MODIFIERS
Packit
577717
The following modifiers are supported on Intel Sandy Bridge R3PQI uncore PMU:
Packit
577717
.TP
Packit
577717
.B i
Packit
577717
Invert the meaning of the event. The counter will now count R3QPI cycles in which the
Packit
577717
event is \fBnot\fR occurring. This is a boolean modifier
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 R3QPI 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 [0:15].
