From 15e3657e433f0e370632fdb70889eb6dfafeba34 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Wed, 6 Sep 2017 14:30:40 +0200 Subject: etnaviv: optimize RS transfers Currently we are blitting the whole resource when the RS is used to de-/tile a resource. This can be very inefficient for large resources where the transfer is only changing a small part of the resource (happens a lot with glTexSubImage2D). Optimize this by only blitting the tile aligned subregion of the resource, which the transfer is going to change.
