Mesa now builds with -Dgallium-drivers=swrast,virgl for Redox target. Fixes: - virgl_screen.c: wrapped disk cache creation in #ifndef __redox__ (build_id_find_nhdr_for_addr uses dl_iterate_phdr — unavailable on Redox) - bits/safamily-t.h: provided to cross-compiler toolchain sysroot Durable patch: - local/patches/mesa/P4-virgl-redox-disk-cache.patch (25 lines) This enables hardware-accelerated 3D rendering in QEMU via virtio-gpu + virgl. Mesa EGL/GLES2/GBM now support the virgl gallium driver alongside llvmpipe software renderer. 63MB pkgar artifact with virgl support.
