The version we used does not advertise GL_EXT_color_buffer_half_float with llvmpipe even though the functionality seems to work. If the extension is not advertised, the future commit "tests: extend output-damage to GL shadow framebuffer" will result in a test failure. Upgrade Mesa, this gets the extension advertised and the test is happy. Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
