Priority: medium Bug ID: 79417 Assignee: dri-devel@lists.freedesktop.org Summary: r600-cayman: GPU lockup in Planetary Annihilation (PTE 66705) on HD6950 Severity: normal Classification: Unclassified OS: Linux (All) Reporter: sxx.public@yahoo.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa

Created attachment 100117 --> https://bugs.freedesktop.org/attachment.cgi?id=100117&action=edit dmesg output when GPU locked up

This report partially related to bug 68527, but It's have to be new task because since yesterday's update game is using OpenGL 3.3 core profile which make it compatible with open source drivers. Game is tested and working on Intel HD4600 and LLVMPipe.

Unfrortunately running it on HD6950 with R600 still result in GPU lockup. As in old task one of problems is complicated sun shader, but even if I remove this one I still get GPU lockup and I have no idea what else might cause issue.

I made two traces using git version of APItrace, both traces takes when game running on Intel HD4600. First trace is with sun shader: https://drive.google.com/file/d/0B5LwC3WbdQ3DWjFJaVRiNndVdk0/edit?usp=sharin... Second without sun shader: https://drive.google.com/file/d/0B5LwC3WbdQ3DOC1JVFhFTHdObVE/edit?usp=sharin... Both traces lockup GPU and X when I try to replay them on HD6950.

Useful part of "dmesg" output attached to task too.

PS: My system info: Ubuntu 14.04 with kernel 3.14 and Mesa from Oibaf PPA: OpenGL Renderer: Gallium 0.4 on AMD CAYMAN OpenGL Version: 3.3 (Core Profile) Mesa 10.3.0-devel (git-ecee4c4 trusty-oibaf-ppa)
