Yes, I saw this way in other serial drivers. But, if then, there are two questions for me: 1. Why did some serial drivers need an UN_SHARED irq? 2. How can we choose a right way?
If your hardware can support sharing an IRQ then shared is the right way - along with the test Arnd suggested. Some hardware lacks the needed facilities to handle shared interrupt. Alan
