libpfm_amd64_k8 — support for AMD64 K8 processors
#include <perfmon/pfmlib.h> PMU name: amd64_k8_revb, amd64_k8_revc, amd64_k8_revd, amd64_k8_reve, amd64_k8_revf, amd64_k8_revg PMU desc: AMD64 K8 RevB, AMD64 K8 RevC, AMD64 K8 RevD, AMD64 K8 RevE, AMD64 K8 RevF, AMD64 K8 RevG
The library supports AMD K8 processors in both 32 and 64-bit modes. They correspond to processor family 15.
The following modifiers are supported on AMD64 K8 processors:
Measure at user level which includes privilege levels 1, 2, 3. This corresponds to PFM_PLM3. This is a boolean modifier.
Measure at kernel level which includes privilege level 0. This corresponds to PFM_PLM0. This is a boolean modifier.
Invert the meaning of the event. The counter will now count cycles in which the event is not occurring. This is a boolean modifier
Enable edge detection, i.e., count only when there is a state transition. This is a boolean modifier.
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].
