From df13588d2176dcf4800a882d926f389667772b46 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Wed, 24 Jan 2018 11:51:08 -0800 Subject: [PATCH] i965: Stop disabling aux during texture preparation Previously, we were handling self-dependencies by marking the render buffer and then passing disable_aux=true to prepare_texture so that it would do a resolve. This works but ends us up doing to much resolving in some cases. Specifically, if we're doing something such as mipmap generation, this would cause us to resolve all levels of the texture if even one of them is overlapping. Instead, this commit makes us wait until we process the framebuffer to do these resolves and we only resolve the slices needed for rendering. Doing this resolve puts them into the pass-through state so, even if we do texture using CCS_E, the CCS data will effectively be ignored and the real surface contents read.
