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?
I have no idea.
So I prepare the patch 2 to use the input flags:
* [PATCH 2/4] amdgpu: set va flag with input parameter
Nicolai handled both issues by creating a new function where the BO is
optional and the flags taken into account.
Please take a look at his patches, they are on the mailing list.
Christian.

Subject: Re: [PATCH 0/4] [libdrm] support PRT and replace interface
Nicolai already proposed patches for PRT support in libdrm (except the
CLEAR/REPLACE addition).
They look a bit cleaner and where posted first, I think we should use them
instead.
Christian.
