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
