Re: [RfC PATCH] drm: fourcc byteorder: brings header file comments in line with reality.

  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.

That is part of the problem.
And even ppc is moving to little endian these days ...
