If we want to support multi-function : PCMCIA/CardBus cards, we *must* do shared interrupts, and multi-function : cards are becoming the standard, rather than the exception. Too bad is acceptible in this context. Meaning that we can still support sharing the interrupt, but it might lock more of the kernel out than if you didn't share. That's not a big deal in the near term. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
