[PATCH 4/5] drm/bochs: fix DRM_FORMAT_* handling for big endian machines.
Use DRM_FORMAT_HOST_XRGB8888, so we are using the correct format code
on bigendian machines. Also add DRIVER_PREFER_HOST_BYTE_ORDER driver
feature flag so drm_mode_addfb() asks for the correct format code.
Create our own plane and use drm_crtc_init_with_planes() instead of
depending on the default created by drm_crtc_init(). That way the plane
format list is correct on bigendian machines.
With this patch applied both ADDFB a...

[PATCH 5/5] drm/virtio: fix DRM_FORMAT_* handling
Use DRM_FORMAT_HOST_XRGB8888, so we are using the correct format code
on bigendian machines. Also add DRIVER_PREFER_HOST_BYTE_ORDER driver
feature flag so drm_mode_addfb() asks for the correct format code.
Both DRM_FORMAT_* and VIRTIO_GPU_FORMAT_* are defined to be little
endian, so using a different mapping on bigendian machines is wrong.
It's there because of broken drm_mode_addfb() behavior. So with
drm_mode_addfb() be...
