hsa-snoop detects the HSA AQL queues and SDMA copy queues an application uses to talk to an AMD GPU, tracks their ring-buffer addresses (virtual and physical), decodes the packets flowing across them (kernel dispatches, barriers, agent dispatches, and SDMA DMA copies), and emits a Perfetto trace with queue-observed timing, kernel names, launch dimensions, copy byte counts and directions, and more.
