libpfm_amd64_fam15h - support for AMD64 Family 15h processors
Синопсис (Synopsis)
#include <perfmon/pfmlib.h>
PMU name: amd64_fam15h_interlagos
PMU desc: AMD64 Fam15h Interlagos
PMU name: amd64_fam15h_nb
PMU desc: AMD64 Fam15h Northbridge
Описание (Description)
The library supports AMD Family 15h processors core PMU in both
32 and 64-bit modes. The uncore (NorthBridge) PMU is also
supported as a separate PMU model.
Модификаторы (Modifiers)
The following modifiers are supported on AMD64 Family 15h core
PMU:
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.
h Measure at while executing in host mode (when using
virtualization). This corresponds to PFM_PLMH. This
modifier is available starting with Fam10h. This is a
boolean modifier.
g Measure at while executing in guest mode (when using
virtualization). This modifier is available starting with
Fam10h. 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].
The uncore (NorthBridge) PMU does not support any modifiers.
