So the conclusion of further investigation is: - The right fix is to fix qemu to flip endian - There's an open discussion as to whether qemu could do it automatically when the guest endian changes on powerpc as a quick fix, the long run approach is to have a register to control it, I'm working on it. offb can then "learn" to flick it like it does the palette hack today. - If we want to ever support foreign endian offb with X, we need to do things a bit differently based on the foreign endian bit that is already there. - We must revert the existing cmap swap patch from the kernel, it's broken and will break things when we fix qemu (and breaks with real HW in LE mode). I've sent a revert request to Linus and CC'ed stable.
