Summary: E-350 misprocesses shader Product: Mesa Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: curaga@operamail.com
Created an attachment (id=50154) --> (https://bugs.freedesktop.org/attachment.cgi?id=50154) Screenshot of the failure
If you pull from my e350bug branch ( http://cgit.freedesktop.org/~cand/mesa/log/?h=e350bug ) and execute "pp_jimenezmlaa=8 glxgears", you should see a fully white window. What actually happens on the E-350 is attached.
The gist is "a long shader; output = white;", which should always create white, since the shader has no kilp/discard. While this would rarely happen in practise (the glsl compiler would eliminate dead code), this is a clear bug, and I believe this is causing me other grief.
While the branch is based on ~4 weeks old master, the bug is present when merged with today's master.
The kernel I'm on is 3.0.1.
