Bruce Evans a84c84f5b0 Reduce i/o overheads by not preserving the channel access register in ... interrupt handlers. Instead, load and use it atomically as necessary. This reduces mode switching overhead for "polled" mode interrupt handling from 5 i/o's to 3 (per service type, per port) so that polled mode is only slightly more inefficient than "interrupt" mode.		1998-11-22 17:40:32 +00:00
