Ahem, not really. XRGB is the only one which works in practice, and virtio-gpu kms driver will stop advertising anything else soon (patches should land upstream with the next merge window). > Add these formats in the switch converting pixman to SDL format > constants so a guest cannot crash the VM by triggering the > g_assert_not_reached() with an unsupported format. Do you have a reproducer for that? There is sdl2_2d_check_format() which reports the supported formats. If we hit sdl2_2d_switch() with a format not whitelisted by sdl2_2d_check_format() we have a bug somewhere in qemu ... cheers, Gerd
