Hi Leo,
I saw the code in dri3_glx.c and I could somewhat relate some basic
code structure
to the vl_winsys_dri3.c. But I am new to this and not aware of the
terminology
that you used about the buffers. Could you please explain what needs
to be done
in more detail or point me to where I can read about it.
I believe it's from loader_dri3_helper.c with "is_different_gpu"
condition true, that will include back buffer and front buffer case.
you could try only back buffer case for now.
Regards,
Leo

Hi Nayan,
About the Prime, I think you have to do is to separate decoder
render buffer and presentation back buffer,
and copy back and forth between them for presentation and update.
You might refer to similar implement
in glx and egl from loader_dri3_helper.c by grep "is_different_gpu"
Regards,
Leo

Thanks, Michel you saved a lot of my time.
Christian, I will get in touch with Leo and get started on this
task.

Hi Christian,
You missed a few things in the merge. I will send in
the updated patch.
I looked at the code in vl_winsys.c and vl_winsys3.c
and also
at the code in presentation.c where delayed rendering
is used. I was trying
to compile using vl_dri3_screen_create() but its
giving me some error. I
will look into the error tonight. My hardware has
PRIME configuration. So
is my hardware suitable for it?
The code in vl_winsys_dri3.c doesn't support PRIME yet.
Might not be too
hard to add though. Grep for "is_different_gpu". Leo
might have done
some work on this, so coordinate with him before spending
too much
effort on this.
Thanks for the note, I assumed Leo already implemented that,
but wasn't 100% sure.
Nayan since you are one of the few contributors with a prime
configuration I think it would make sense for you to hack on
this first.
Would also help getting you into the code and a bit more into
the stack in general.
Regards,
Christian.
