Priority: medium Bug ID: 70108 Assignee: dri-devel@lists.freedesktop.org Summary: [bisected e64633e8c3a5498998a45ab721bf80edca101cf5] regression: bad rendering on r600g Severity: normal Classification: Unclassified OS: All Reporter: alexandre.f.demers@gmail.com Hardware: Other Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa

I noticed a couple of days ago a regression on some demo applications where the light or shadows wouldn't be rendered correctly. They form lines. This can be observed testing Unigine where light reflecting on water or on the dock will not be rendered correctly.

Bisecting gave me the following result: git bisect bad e64633e8c3a5498998a45ab721bf80edca101cf5 is the first bad commit commit e64633e8c3a5498998a45ab721bf80edca101cf5 Author: Marek Olšák marek.olsak@amd.com Date: Sun Sep 22 13:06:27 2013 +0200

r600g,radeonsi: share r600_texture.c

The function r600_choose_tiling is new and needs a review.

The only change in functionality is that it enables 2D tiling for compressed textures on SI. It was probably accidentally turned off.

v2: don't make scanout buffers linear
