Furthermore, the method periodically chooses an active wave (in a round robin manner) and snapshot it's program counter (PC). The process takes place on every compute unit simultaneously which makes it device-wide PC sampling. The outcome is the histogram of samples that says how many times each kernel instruction was sampled. **Note**: The PC sampling feature is still under development and may not be completely stable. - **Risk Acknowledgment**: - - By activating this feature through `ROCPROFILER_PC_SAMPLING_BETA_ENABLED` environment variable, you acknowledge and accept the following potential risks: - - **Hardware Freeze**: This beta feature could cause your hardware to freeze unexpectedly. - - **Need for Cold Restart**: In the event of a hardware freeze, you may need to perform a cold restart (turning the hardware off and on) to restore normal operations. - Please use this beta feature cautiously. It may affect your system's stability and performance.
