Summary

  • preserve an explicit TRITON_PTXAS_PATH for fish-speech
  • otherwise select an executable ptxas from CUDA_HOME (default /usr/local/cuda)
  • document the compile:true option and add shell-level regression coverage

Testing

  • bash scripts/build/fish-speech-ptxas_test.sh
  • make test-build-scripts
  • git diff --check

Closes #11348

Prefer an explicitly configured Triton assembler, otherwise use the executable ptxas from CUDA_HOME so torch.compile can target GPU architectures newer than Triton bundled tooling.
