libpfm_amd64_fam16h - support for AMD64 Family 16h processors
#include <perfmon/pfmlib.h>
PMU name: amd64_fam16h
PMU desc: AMD64 Fam16h Zen
The library supports AMD Family 16h processors core PMU in both 32
and 64-bit modes.
The following modifiers are supported on AMD64 Family 16h 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].
