+# MiniPC-8845 Arch WSL GPU Runner
+
+Configuration recorded on 2026-10-05.
+
+## Host
+
+| Component | Configuration |
+| --- | --- |
+| Hostname | `MiniPC-8845` |
+| Windows build | `10.0.26200.9445` |
+| GPU | AMD Radeon 780M Graphics |
+| Windows GPU driver | `32.0.12033.1030` |
+| WSL version | `2.7.3.0` |
+| Distribution | `archlinux`, Arch Linux on WSL 2 |
+| Linux kernel | `6.6.114.1-microsoft-standard-WSL2` |
+| Init system | systemd |
+| WSL networking | Mirrored |
+| GPU access | `/dev/dxg` and `/usr/lib/wsl/lib` |
+
+## GitHub Actions Runner
+
+| Setting | Value |
+| --- | --- |
+| Repository | `MobileGL-Dev/MobileGL` |
+| Runner name | `minipc-8845-arch-wsl-gpu` |
+| Runner version | `2.337.0`, automatic updates enabled |
+| Labels | `self-hosted`, `Linux`, `X64`, `arch`, `wsl`, `gpu`, `gles`, `vulkan`, `d3d12` |
+| Concurrent jobs | 1 |
+| Linux account | `github-runner`, UID 1001, no sudo configuration |
+| Installation directory | `/opt/actions-runner/mobilegl` |
+| Work directory | `/opt/actions-runner/mobilegl/_work` |
+| Environment file | `/etc/mobilegl-runner/gpu.env` |
+
+Workflow runner selector:
+
+```yaml
+runs-on: [self-hosted, Linux, X64, arch, wsl, gpu, gles, vulkan]
+```
+
+## Graphics
+
+| Component | Configuration |
+| --- | --- |
+| Mesa | `26.2.1-arch1.1` |
+| OpenGL / GLES driver | Mesa D3D12 |
+| Renderer | `D3D12 (AMD Radeon 780M Graphics)` |
+| EGL | 1.5 |
+| OpenGL | 4.6 |
+| OpenGL ES | 3.1 |
+| Vulkan driver | Mesa Dozen, translating Vulkan to D3D12 |
+| Vulkan device API | 1.2.354 |
+| Vulkan ICD | `/usr/share/vulkan/icd.d/dzn_icd.json` |
+| Default EGL platform | Surfaceless |
+
+Dozen reports a non-conformant Vulkan implementation. The exposed capabilities
+are GLES 3.1 and Vulkan 1.2; GLES 3.2 and full Vulkan conformance are not available.
+
+The runner service selects the Radeon GPU with these environment variables:
+
+```sh
+DISPLAY=:0
+WAYLAND_DISPLAY=wayland-0
+XDG_RUNTIME_DIR=/mnt/wslg/runtime-dir
+LD_LIBRARY_PATH=/usr/lib/wsl/lib
+MESA_LOADER_DRIVER_OVERRIDE=d3d12
+GALLIUM_DRIVER=d3d12
+MESA_D3D12_DEFAULT_ADAPTER_NAME="AMD Radeon 780M Graphics"
+VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/dzn_icd.json
+EGL_PLATFORM=surfaceless
+PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
+```
+
+The installed GPU probe is `/usr/local/libexec/mobilegl-runner/gpu-smoke`.
+Its GLES source is `/usr/local/libexec/mobilegl-runner/gles-smoke.c`, and the
+recorded verification log is `/var/log/mobilegl-runner/gpu-smoke.log`.
+
+## Build Tools
+
+Installed tools include GCC, Clang 22, CMake, Ninja, ccache, LLD, libc++, Git LFS,
+GitHub CLI, and EGL/GLES/Vulkan development headers.
+
+## Service and Startup
+
+| Setting | Value |
+| --- | --- |
+| systemd unit | `actions.runner.MobileGL-Dev-MobileGL.minipc-8845-arch-wsl-gpu.service` |
+| Service drop-in | `/etc/systemd/system/actions.runner.MobileGL-Dev-MobileGL.minipc-8845-arch-wsl-gpu.service.d/gpu.conf` |
+| Service startup | Enabled at WSL systemd boot |
+| Restart policy | `Restart=always`, `RestartSec=15` |
+| Startup checks | GPU device access and WSLg X11/Wayland sockets |
+| Windows scheduled task | `MobileGL Arch WSL Runner` |
+| Task trigger | Windows login by `Swung0x48` |
+| Task behavior | Starts WSL in a hidden window and keeps it running |
+| Task execution limit | Unlimited |
+| Task retry policy | Every minute, up to 999 retries |
+
+Automatic startup requires the Windows user to log in. The runner cannot execute
+jobs while the host is asleep.
+
+## Network
+
+The runner uses the Windows Clash proxy through WSL mirrored networking:
+
+```sh
+http_proxy=http://127.0.0.1:7897
+https_proxy=http://127.0.0.1:7897
+no_proxy=localhost,127.0.0.1,::1
+```
+
+Clash must be running for the runner's configured GitHub connection to work.
