Hi,

ppc64 (big endian) virtual machine, running with qemu stdvga & bochs-drm
driver. Xorg with modesetting driver uses DRM_FORMAT_XRGB (one and
only format supported by bochs-drm), and we have to interpret that in
bigendian byt

Ok, this is really a kickstart for a discussion. While working on
graphics support for virtual machines on ppc64 (which exists in both
little and big endian variants) I've figured the comments in the header
file don't match reality. They are not considered little endian (as
