Hi Here you are a patch that adds big endian support for rv730 in r600 classic mesa driver. The BE modifications are almost the same as the DRM / DDX driver modifications (http://lists.freedesktop.org/archives/dri-devel/2011-February/008151.html).
I used the mesa-demos to test the driver status on big endian platform. Nearly all demos renders the same as on Intel architecture. Nevertheless, there are still some issues in glReadPixels (r600_blit) with some formats. I can't figure out exactly what and when data must be swapped (set_tex_resoures, set_render_target...). Review of the patch would be greatly appreciated. It seems that r600g will be the default for Mesa 7.11 so I'll try to enable big endian support for Gallium now.
