Hi,
Little series to fix xorg display on virtio on bigendian machines.
First patch factors out the drm -> virtio format mapping code into
a helper function, second patch actually fixes the issue using the
new helper.
cheers,
Gerd

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] 21+ messages in thread
