Profiling capabilities of AMDuProfPcm might be
limited on a virtual machine. Check the following hardware and OS primitives provided by
host or guest operating system to determine the level of support. Run the command
AMDuProfCLI info –system to obtain this information and look for
the following sections.| Item | Description |
|---|---|
| PERF Features Availability | Availability of Core, L3 and DF PMCs on the system. If any of the PMCs are unavailable, the corresponding metrics will not be supported. Ex. On guest VMs, DF PMCs are not accessible due to security reasons, due to which DF metrics such as memory, xgmi, pcie cannot be collected. |
| Hypervisor Info | Hypervisor vendor and support can be used to determine if the hypervisor is supported. Also determine the mode – host or guest. Usually the host has unrestricted access to all the PMCs. |
