* WSL ROCm: generalize ROCm-on-WSL bootstrap from Strix-only to any RDNA arch
install_rocm_wsl_strixhalo.sh hardcoded gfx1151, so its verify step died on
discrete Radeon cards even though the ROCm + librocdxg setup is arch-agnostic.
Auto-detect the GPU arch from rocminfo (override via UNSLOTH_WSL_GFX), verify any
GPU agent enumerates over DXG, and map the arch to AMD's per-arch wheel family for
the optional smoke test (injecting librocdxg into torch/lib so torch's bundled
ROCr finds the DXG bridge). Verified on gfx1200 (Radeon RX 9060 XT) in WSL2 +
Ubuntu 24.04 -- torch.cuda now enumerates the GPU.
* WSL ROCm: trigger the ROCm-on-WSL bootstrap for discrete Radeon GPUs too
_maybe_bootstrap_rocm_wsl only fired for Strix APUs (matched via /proc/cpuinfo,
which discrete cards don't appear in). Add _wsl_amd_gpu_name() -- queries the
Windows host via WMI -- and broaden the trigger gate plus the 'already-usable
ROCm' rocminfo check from gfx1151-only to any real GPU agent (gfxNNNN, excluding
the gfx11-generic fallback ISA). The generalized bootstrap then auto-detects the
arch. Enables 'curl install.sh | sh' to set up ROCm-on-WSL on discrete Radeon RX
7000/9000 in WSL2 + Ubuntu 24.04, not just Strix Halo/Point.
* WSL ROCm: address review -- filter generic ISA in bootstrap, bound the host GPU query
- install_rocm_wsl_strixhalo.sh: exclude the gfx11-generic fallback ISA in arch
detection (grep -v generic), matching install.sh's rocminfo check, so a generic
agent listed before the real one can't be picked as the arch.
- install.sh: wrap the powershell.exe Win32_VideoController query in _run_bounded
(10s timeout) so an unstable WSL-interop / busy host can't hang the installer.
* WSL ROCm: harden arch-detect + librocdxg copy under set -eo pipefail (review)
- _detected_gfx: append '|| true' so a no-GPU rocminfo (empty pipeline, non-zero
under pipefail) doesn't abort the assignment before the '[ -z ]' branch prints
the diagnostic + die message.
- smoke-test librocdxg copy: gate on '[ -d "$_tlib" ]' instead of '[ -n ]' so a
non-directory value can't make cp rename librocdxg to 'lib'.
* WSL ROCm: address Codex review (gfx000, 24.04 reroute for discrete, test locator)
- Exclude gfx000 (the CPU agent) from the WSL 'usable ROCm' check and the bootstrap
arch-detect: match gfx[1-9] (nonzero arch), so a partial ROCm install that only
reports the CPU ISA no longer short-circuits the librocdxg setup. (P2)
- Reuse the Ubuntu-24.04 reroute for discrete Radeon: broaden
_maybe_reroute_strixhalo_to_2404's gate with the same _wsl_amd_gpu_name (WMI)
fallback, so a discrete card on 26.04 reroutes to a 24.04 distro like Strix does
instead of falling to CPU. Moved _wsl_amd_gpu_name above the reroute and made it
self-contained + 10s-bounded (it runs before _run_bounded is defined). (P2)
- Update TestInstallShDropinPersistence to locate the gate by its unique
'!/generic/' clause now that the gfx1151 literal is gone. (P1)
* Condense ROCm-on-WSL comments in install.sh and bootstrap helper
* Guard WSL reroute from NVIDIA hybrid hosts and fix GFX-override pipefail check
* Honor CUDA_VISIBLE_DEVICES-hidden NVIDIA in the WSL reroute guard
* Reuse _has_usable_nvidia_gpu in the WSL reroute guard
