Модификаторы (Modifiers)
The following modifiers are supported on Intel Atom processors:
u
Measure at user level which includes privilege levels 1,
2, 3. This corresponds to PFM_PLM3
. This is a boolean
modifier.
k
Measure at kernel level which includes privilege level 0.
This corresponds to PFM_PLM0
. This is a boolean modifier.
i
Invert the meaning of the event. The counter will now
count cycles in which the event is not
occurring. This is
a boolean modifier
e
Enable edge detection, i.e., count only when there is a
state transition. This is a boolean modifier.
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].
t
Measure on both threads at the same time assuming hyper-
threading is enabled. This is a boolean modifier.
