Hi, > which software have you used as representative of "reality"? ppc64 (big endian) virtual machine, running with qemu stdvga & bochs-drm driver. Xorg with modesetting driver uses DRM_FORMAT_XRGB8888 (one and only format supported by bochs-drm), and we have to interpret that in bigendian byte order on the host side to get a correct display. Didn't try wayland. Can do, but will take a while. Don't have a wayland-capable guest install at hand, and installing one takes a while because I don't have a physical pseries and emulation is slooooww. > To solve that problem, we would like to know if anything existing would > break for each possible solution, but no developers using BE have really > turned up. That is part of the problem. And even ppc is moving to little endian these days ... cheers, Gerd
