Kernel has been compiled. But when I use xenomai source package generates real-time testing tools to test.The latency tools works well with no load. But when I start the opengl tools gfxgears the real-time will be very bad with kernal mode priority 99 100us。
I do not kenow where I have been wrong.

If you are using the graphic chip integrated into Intel processors,
this has only be fixed recently in the kernel (it works on 3.10, but
not on older kernel). If you want to stay with 3.4, see:

If your graphic hardware is based on Intel's i915 chipset, you will need
these two patches on top of 3.8:

7aa1bd6 Revert "drm/i915: Workaround incoherence between fences and LLC
across multiple CPUs"
08d4be4 drm/i915: Fix incoherence with fence updates on Sandybridge+

dear Philippe:<br/>Thanks i use the patches you tell me ，but if i turn on i915 with smp and use one glxgears it about 30~40 us delay .When I start much more glxgears the latency to achieve 120 us and I test it just one hour. I do not if it is normal.<br/> thanks !<br/><br/>---<br/>eric
