Direct3D 9 State Tracker Work Leads To Nouveau Improvements

Last year experimental Direct3D 9 support came to Linux via a third-party Mesa tree that introduced a new Gallium3D state tracker and modifications to get this D3D9 support working with the open-source NVIDIA (Nouveau) driver. The Direct3D 9 support was never merged into mainline Mesa/Gallium3D, but some fixes as a result of that work is now queued up for likely landing.

Ilia Mirkin, one of the most prolific Nouveau contributors in recent times, has cherry-picked 12 patches for the NV50 and NVC0 Gallium3D drivers from the "gallium-nine" branch that contains the out-of-tree Direct3D 9 state tracker support. These 12 patches address issues within the Nouveau Gallium3D drivers that are of benefit outside of the Direct3D realm.

Mirkin wrote, "I went through the gallium-nine tree and picked out nouveau patches that are general bug-fixes. The first bunch I'd like to also get into 10.2. I've reviewed all of them and they make sense to me, but sending them out for public review as well in case there are any objections."
