From f30aab76961564e2f0ce34af7d7b38ec43535877 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Wed, 12 Apr 2017 16:13:36 +0200 Subject: [PATCH] etnaviv: stop repeatedly resolving an unchanged resource into its scanout prime buffer Before resolving a resource into its scanout prime buffer, check that the prime resource is actually older. If it is not, the resolve is an expensive no-op, and we better skip it.
