Summary: OpenGL applications cause kernel to complain "Going to
lose the write domain"
Product: DRI
Version: XOrg CVS
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM modules
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
On Fedora rawhide the kernel dumps the following messages to the log at a
blinding rate while running an opengl application (I know it happens when I run
glxgears and it seems compiz as well, my only two test points),
Sep 16 14:14:50 mercury kernel: [drm:i915_gem_execbuffer] *ERROR* Going to lose
the write domain on obj 38 size 16777216
Sep 16 14:14:50 mercury kernel: [drm:i915_gem_execbuffer] *ERROR* Going to lose
the write domain on obj 40 size 16777216
Meanwhile, glxgears consistently shows 40fps without compiz. compiz produces 30
fps and down to 14 while switching workspaces with the desktop wall plugin.
