The display device supports switching the endianess for the framebuffer, at least with kernel 3.19+ and qemu 2.2+. Default endianness depends on the machine type, i.e. ppc64 guests get a bigendian framebuffer and pretty much everything else a little endian framebuffer on reset. The bochs-drm driver switches the display into native endian mode, i.e. big endian for ppc64 and little endian for ppc64le kernels.

In some way yes, in some way no. Tried wayland meanwhile (using "gnome-shell --wayland"). Looks pretty much the same. Window decorations look a bit different (good on xorg, broken on wayland), probably because window decorations work completely different. Otherwise it is bug compatible to xorg. Probably because gnome-shell composites everything using llvmpipe, so it's largely the same code running on both xorg and wayland, which then finally scans out to a dumb framebuffer. cheers, Gerd _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
