# Hardware compatibility
|
|
|
|
JARVIS-QVAC has one inference owner: `jarvisd` owns the QVAC master and every
|
|
model call goes through `daemon/qvac-master.js`. The harness, media jobs, and
|
|
computer-use tools do not start competing QVAC servers. The GPU gate is strict:
|
|
when QVAC cannot report a usable GPU backend, inference fails with a truthful
|
|
diagnostic instead of silently falling back to CPU.
|
|
|
|
| Hardware path | Recommended profile | Expected backend | Notes |
|
|
| --- | --- | --- | --- |
|
|
| AMD Vulkan | laptop-16gb or desktop-gpu | Vulkan/llama.cpp | Verify the QVAC runtime sees the ICD, not only `vulkaninfo`. |
|
|
| NVIDIA CUDA | desktop-gpu | CUDA/cuBLAS | Install a driver compatible with the QVAC build and verify VRAM. |
|
|
| Intel Vulkan | laptop-16gb | Vulkan | Use a current Mesa stack; larger media jobs may remain queued. |
|
|
| CPU only | unsupported for inference | none | Wake and diagnostics can run, but the master refuses model inference. |
|
|
|
|
Run `npm run gpu-doctor` before downloading models. `assessModelFit()` should
|
|
select the largest profile that fits reported VRAM; an unavailable model stays
|
|
visible as unavailable and never causes the voice loop to crash. The current
|
|
machine's GPU visibility is an installation concern when this document is
|
|
updated; record the exact doctor output in the release checklist.
