# Hearthwave — AMD ROCm deployment (build-from-source).
# Standalone: run directly, no base file needed:
#   bash setup-rocm.sh           # one-time host prep + model staging
#   docker compose -f docker-compose.rocm.yml up --build
#
# Runs the STT final pass on an AMD GPU via ROCm. The streaming pass stays on
# CPU. Requires: amdgpu kernel driver, the host 'render' group, and (for
# unsupported GPUs like the Radeon 680M / gfx1035) HSA_OVERRIDE_GFX_VERSION.
# setup-rocm.sh writes RENDER_GID / HSA_OVERRIDE_GFX_VERSION / PULSE_UID to .env.
