From 3e55df4f83962b4dd29d84be57b697dccab5a364 Mon Sep 17 00:00:00 2001 From: "Kristian H. Kristensen" Date: Mon, 5 Nov 2018 21:23:27 -0800 Subject: [PATCH] freedreno: Add support for EXT_multisampled_render_to_texture There is not much to do in freedreno - tile layout and multisample state for gmem renderings is programmed based on the pfb sample count, while resolve blits take the destination sample count from the resource.
