# 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.
