From 939486d3d30caf434b93e1d2ccd10f5b2a06ed4d Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Mon, 12 Dec 2016 16:06:55 -0500 Subject: freedreno/a5xx: use MRT0 to import linear zs A bit of a hack, but we need to do this until we can do tiled zs in sysmem (and associated tile/until blits for transfer_map). Fixes xonotic and glmark2 "refract", when reorder wasn't enabled. (reorder would paper over the issue by avoiding the extra round- trip to system memory and back to gmem.
