From d816a51b81f42b0aa4819a32587b4aa167e4b541 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Fri, 8 Jul 2016 02:44:57 -0400 Subject: st/mesa: provide GL_OES_copy_image support by caching the original ETC data MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The additional provision of GL_OES_copy_image is that it work for ETC. However many desktop GPUs don't have native ETC support, so st/mesa does the decoding by hand. Instead of discarding the compressed data, keep it around in CPU memory. Use it when performing image copies.
