[Mesa-users] Etnaviv support in Mesa

[Albert Freeman]

Also note --with-dri-driverdir= depends on X configure options I believe.
And if when compiling pthread stubs gives you an issue delete it from
the Makefile:
diff -ur mesa-orig/configure.ac mesa-origb/configure.ac

It dosen't appear etnaviv uses llvm/clang, and you probably don't want
with-sha1 or opencl so:
./configure --prefix=/usr \
    --sysconfdir=/etc \
    --with-dri-driverdir=/usr/lib/xorg/modules/dri \
    --with-gallium-drivers=etnaviv \
    --with-dri-drivers= \
    --with-egl-platforms=x11,drm,wayland \
    --disable-xvmc \
    --enable-shared-glapi \
    --enable-egl \
    --enable-glx \
    --enable-glx-tls \
    --enable-gles1 \
    --enable-gles2 \
    --enable-gbm \
    --enable-dri \
    --enable-texture-float
