thorpej	fc96443d15	New callout mechanism with two major improvements over the old timeout()/untimeout() API: - Clients supply callout handle storage, thus eliminating problems of resource allocation. - Insertion and removal of callouts is constant time, important as this facility is used quite a lot in the kernel. The old timeout()/untimeout() API has been removed from the kernel.	2000-03-23 07:01:25 +00:00
thorpej	f76ce3b475	Only poll for bell completion if we're calling in from cnbell(). Fixes a problem reported by Lennart Augustsson.	2000-03-10 06:10:34 +00:00
thorpej	42144199a1	- Make the pcppi and pckbd drivers cooperate a little more -- pckbd provides a call to hook up a bell-ringer (since the keyboard itself has no bell). This eliminates the need for #ifdefs for the bell-ringer in the pckbd driver. - Add cnbell() support to pckbd.	2000-03-06 21:40:08 +00:00
