libpfm_amd64_fam17h - support for AMD64 Family 17h processors
#include <perfmon/pfmlib.h>
PMU name: amd64_fam17h (deprecated), amd_fam17h_zen1
PMU desc: AMD64 Fam17h Zen1
The library supports AMD Family 17h processors Zen1 core PMU in
both 32 and 64-bit modes. The amd64_fam17h PMU model name has been
deprecated in favor of amd_fam17h_zen1. The old name is maintained for
backward compatibility reasons, but should not be used anymore.
The following modifiers are supported on AMD64 Family 17h Zen1
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].
