Should we patch drm_fourcc.h and essentially state that _all_ drm_fourcc are in native endian, don't dare mixing things up? Would be good to send out an rfc and discuss it with radeon/amd maintainers. Afaik they are the only ones who also care about some big endian platforms.

Well, I don't think this needs clarification. I never assumed that fourcc is something else than native endian. It really was just an oversight in the virtio driver. One code path (which creates the framebuffer for fbdev emulation) did proper drm_fourcc -> virtio format mapping, including endianness handling. Patch 1/2 of this series factors this code out into a helper function so we can easily reuse it. The other code path (for creating dumb buffers) had the virtio format hardcoded which happened to work correctly in the little endian case. cheers, Gerd ^ permalink raw reply [flat|nested] 7+ messages in thread
