libpfm_amd64_fam1ah_zen5 - support for AMD64 Family 1Ah
processors
#include <perfmon/pfmlib.h>
PMU name: amd64_fam1ah_zen5
PMU desc: AMD64 Fam1Ah Zen5
The library supports AMD Family 1Ah processors Zen5 core PMU in
both 32 and 64-bit modes.
The following modifiers are supported on AMD64 Family 1Ah Zen5
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].
