The newbus routines use a certain amount of overhead, but once done, you forget about it. In some device drivers, the probe methods often need to try a variety of hardware ports. In the past, inb/outb was used, along with an often hardcoded port address. Does it make sense to call bus_allocate_resource for every hardware port we probe? What is the best way to handle this so NO inb/out is used, even for probing? jcm -- "I drank WHAT ?!" - Socrates To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
