PC sampling service

Services

• PC sampling stochastic method

Properties

• Iterate through all gpu agents that supports PC sampling.
• Iterate through the supported configuration for that agent.
• The configure_pc_sampling_prefer_stochastic function is responsible for configuring PC sampling on a given GPU agent. It attempts to select a stochastic sampling configuration if available, falling back to a host-trap configuration otherwise.
• rocprofiler_pc_sampling_callback function processes PC sampling records delivered by the profiler. It validates the records, determines their type, and delegates the printing of their details to the appropriate print_sample function.
