.SH DESCRIPTION

The library supports AMD K8 processors in both 32 and 64-bit modes. They correspond

to processor family 15.

.SH MODIFIERS

The following modifiers are supported on AMD64 K8 processors:

.TP

.B u

Measure at user level which includes privilege levels 1, 2, 3. This corresponds to \fBPFM_PLM3\fR.

This is a boolean modifier.

.TP

.B k

Measure at kernel level which includes privilege level 0. This corresponds to \fBPFM_PLM0\fR.

This is a boolean modifier.

.TP

.B i

Invert the meaning of the event. The counter will now count cycles in which the event is \fBnot\fR

occurring. This is a boolean modifier

.TP

.B e

Enable edge detection, i.e., count only when there is a state transition. This is a boolean modifier.

.TP

.B c

Set the counter mask value. The mask acts as a threshold. The counter will count the number of 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].
