Hi guys,
this patch set cleans up the handling of TTM buffer objects quite a bit by allowing to create them without allocating a ttm_resource as well.
That's not only cleaner in general, but also a necessary prerequisite for quite a number of related work.
Maybe there's some threads I missed, but I can't really guess what this could be useful for without even a hint.
Well about a week ago Bob send me a partial implementation of this and said he needs it for i915. What exactly i915 needs here I'm not sure about either.
I have this cleanup in the pipeline because amdgpu wants to improve his page table handling with this and independent of those driver use case patches #10 and #11 drop allocating dummy resources for two use cases in TTM.
