This patch is for introducing the irq thread support in drm_irq. Why we need irq thread in drm_irq code? In our GPU system, the gpu interrupt handler need some time even > 1ms to finish, in that case, the whole system will stay in irq disable status. One case is: when audio is playing, it sometimes effects the audio quality. So we have to introduce the irq thread in drm_irq, it can help us move some heavy work into irq thread and other irq interrupts can be handled in time. Also the IRQF_ONESHOT is helpful for irq thread.
