Bug ID: 94581 Summary: Red flood in dmesg when running applications Product: Mesa Version: 11.0 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: mazahakaforever@ya.ru QA Contact: dri-devel@lists.freedesktop.org

Hi there. Im using laptop with hybrid graphics. Intel Core i5-2450m with integrated videocard and AMD Radeon HD 6650m as discrete. My glxinfo output

glxinfo | grep OpenGL OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile OpenGL core profile version string: 3.3 (Core Profile) Mesa 11.0.4 OpenGL core profile shading language version string: 3.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 11.0.4 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.0.4 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00 OpenGL ES profile extensions:

And output with DRI_PRIME set.

DRI_PRIME=1 glxinfo | grep OpenGL OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD TURKS (DRM 2.43.0, LLVM 3.6.2) OpenGL core profile version string: 3.3 (Core Profile) Mesa 11.0.4 OpenGL core profile shading language version string: 3.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 11.0.4 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.0.4 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00 OpenGL ES profile extensions:

So, i guess when im using DRI_PRIME environmental variable as one - kernel tries to use discrete videocard. And when im trying to launch applications (glxgears, etracer, steam) i got many messages in dmesg like this [ 1376.309602] [drm:radeon_cs_parser_relocs [radeon]] *ERROR* gem object lookup failed 0xe [ 1376.309620] [drm:radeon_cs_ioctl [radeon]] *ERROR* Failed to parse relocation -2! [ 1376.822639] [drm:radeon_cs_parser_relocs [radeon]] *ERROR* gem object lookup failed 0xe [ 1376.822661] [drm:radeon_cs_ioctl [radeon]] *ERROR* Failed to parse relocation -2!

Looking forward to some discussion.
