--- Comment #4 from charlie <407883775@qq.com> ---
>>The radeonsi driver currently isn't very well tested on big endian hosts.
>>In theory it should work, but that doesn't mean there might be a lot of bugs.

I test the newest Mesa(10.2.5), The problem is still existing. 
It isn't test very well on big-endian hosts , That means it can work?  I never
analysis the mesa code, The code it too more, and haven't docs, Could you give
me some docs? Or give me some ideals? how to alter this code, pls give me a
direction. 
Thk.
