fegger 098d9b63fa whisper-server: Debian trixie base — Mesa 25 for the R9700 (RDNA 3.5)
bookworm's Mesa 22.3 has no gfx1151 (Strix Halo) support in RADV, so
the container silently fell back to CPU despite gpu=auto: whisper
logged 'whisper_backend_init_gpu: no GPU found'. trixie ships Mesa
25.0.7, which supports the R9700; whisper.cpp builds unchanged on it.

# whisper.cpp inference server for meetrec.
#
# Built from the same pinned whisper.cpp release (v1.9.3) as the Android
# app's JNI layer, compiled statically WITH the Vulkan GPU backend for
# AMD GPUs (Radeon AI PRO R9700 / RDNA, also NVIDIA/Intel). Without a GPU
# present it transparently falls back to CPU.
#
# Note: ggml builds with -march=native by default, so build the image ON
# the machine that will run it (docker compose build on the server).
