I haven't looked at d3d10/11 at all yet.
I did at some point, and despite my initial reservations about llvmpipe I was surprised to discover that there weren't that many failures, and none of them were actually llvmpipe's fault. I was mostly waiting on a resolution to vkd3d's 289 (ftou clamping) so I could take my cue from that in wined3d, but I could probably submit the other fixes now.
