Questions

  1. Is hardware counter profiling via ncu supported on DRIVE Thor (GB10B / tegra264) with the current BSP and public NCU release?
  2. If supported, which NCU package/target should be used? Is there a DRIVE OS-specific NCU target (similar to Nsight Systems’ target-linux-tegra-armv8)?
  3. Are there any required kernel/driver settings to enable perf counter access on this platform?
  4. If not yet supported, what is the recommended profiling workflow for Blackwell embedded (GB10B) — is Nsight Systems the only option for now?
