ROCProfiler PC sampling
Known issues
-
Abnormal process termination with running GPU kernels while PC sampling is active may leak resources, eventually necessitating a GPU reset or system reboot. This is a consequence of the current user-space PC sampling implementation, which must coexist with AMD GPU driver activity in the Linux kernel.
-
The
ioctlused to synchronize with kfd (part of the AMD GPU driver) may pose a bottleneck on systems with multiple HSA GPU agents.
