Interrupt setting
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

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(),
