Hi all, I am a Nouveau user on FC12 with GeForce 9500GT. I have read the Nouveau wiki documents, and they imply that there are ways to set GPU to send interrupts to CPU, when we want to be notified for something, e.g., when DMA transfer or GPU operation is completed. By default, when I run an OpenGL demo application from Gallium3D, the driver gets no interrupts from GPU in nouveau_irq_handler(),
