Hi Christian,

Thanks for your info.
Sorry to miss them...

Actually this a serial of messed function patch, I should send them separately next time.

If we support PRT with bo=NULL, we may need a new VA op.
So please take a look at patch 4:
   * [PATCH 4/4] amdgpu: add a new bo va function to support NULL bo

I also have a question about current VA op func, why we didn't use the input flags?
So I prepare the patch 2 to use the input flags:
    * [PATCH 2/4] amdgpu: set va flag with input parameter


Regards,
Jerry (Junwei Zhang)
