It sounds like this shouldn't affect the IRQ handling of the DRM itself though, does it? > The other problem is that when user IRQs are turned off, more often than > not the display chip starts to issue false IRQs which are not reflected > in the status registers.

You mean i915_driver_irq_uninstall() could trigger this problem? Otherwise, I'm wondering if it could be related to Zou Nan hai's recent vblank interrupt fix. -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer ------------------------------------------------------------------------- Take Surveys.
