commit 4b1143d1cb9820bbf2d4907032262d3452801c5e
Author: James Simmons <jsimm...@infradead.org>
Date: Wed Feb 11 14:42:42 2015 -0700
The function viaDRIFBMemcpy really wants dst to be 16byte-aligned
there. And that's not ->driOffScreenMem (which you've guaranteed
to be aligned), that's ->driOffScreenSave, which comes from malloc().
On 32bit host it's not guaranteed to yield 128bit-aligned pointer.
That's where the "[drm:via_build_sg_info] *ERROR* Invalid DRM bitblt
alignment." kernel whinge is coming from.
