mesa-llvmpipe con gcc/libstdc++ (matchea el ABI de libLLVM; zig-cc usaba libc++ ⇒ undefined symbols en el JIT). qemu-desktop-image inyecta libLLVM.18+libgcc_s+libstdc++. HITO: kwin toma DRM master de virtio-gpu, crea el GBM device (llvmpipe, ya no softpipe), expone compositor y ACEPTA clientes. Muro restante: kwin segfaultea (139) al componer la 1ra superficie con llvmpipe — necesita backtrace (gdb) para diagnosticar. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# Mesa 24.0.9 — LLVMPIPE (render por software CON LLVM JIT). Variante de mesa-swrast (softpipe) para
|
|
# el escritorio KDE en VM: kwin exige un GBM/EGL de software COMPLETO, y softpipe no bindea las
|
|
# extensiones que kwin pide ("failed to bind extensions" → "Failed to create gbm device"). llvmpipe
|
|
# (el driver `swrast` de gallium cuando `-Dllvm=enabled`) sí las provee. Ver [[kde-metal-qemu-desktop]].
|
|
#
|
|
# La ÚNICA diferencia con mesa-swrast.toml es `-Dllvm=enabled` (+ el toolchain LLVM en el sandbox).
|
|
# Si el sandbox no trae libLLVM/llvm-config, este build falla en configure ⇒ hay que sellar LLVM
|
|
# desde fuente primero (el monstruo). Test primero, decidir después.
