<div>I saw the code in dri3_glx.c and I could somewhat relate
some basic code structure</div>

what needs to be done </div>

<br>
I believe it's from loader_dri3_helper.c with "is_different_gpu"
condition true, that will include back buffer and front buffer case.<br>
you could try only back buffer case for now.<br>

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

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