Hi Nayan,<br>
<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>
<br>

<div>Christian, I will get in touch with Leo and get started on

Hi 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>

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>

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>
