[Mesa-dev] [PATCH 2/2] st/vdapu: use lanczos filter for scaling v4

[Leo Liu]

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
