It's not that simple.
The 3DPRIMITIVE indirect registers require you

At least for Ivybridge, I think I want this software path 100% of the
time. We may want to remove the stall on Haswell as a later optimization.
I'd like to have a dedicated flag for this fallback like we have

The new driver hook returns exactly that information.

Gallium drivers already implement this
