thorpej	d49c71cb8a	- Use indicies, rather than pointer arithmetic, to track DMA chain ... segments. - Use a much more obvious DMA job queueing scheme. - Fixup some debugging code.	1997-01-30 09:04:33 +00:00
thorpej	0d6571ba4d	Defer hooking up the DMA controller interrupt. Add a new funciton, ... dmacomputeipl(), which is called by drivers which use DMA once they've hooked up their interrupts. This new function computes the appropriate ipl to use for the DMA controller and (re-)establishes it's interrupt.	1996-12-09 03:09:51 +00:00
christos	30b3cc3d09	backout previous kprintf changes	1996-10-13 03:14:05 +00:00
christos	60dd5ceebe	printf -> kprintf, sprintf -> ksprintf	1996-10-11 00:06:28 +00:00
thorpej	d6f4511690	All interrupt routines (except the HIL; don't ask) now take a pointer ... to a softc, rather than a unit number. Add a "dq_softc" member to struct devqueue; this is a temporary measure until the dma/controller/device callback spaghetti is untangled. YAY! No more need for dcafastservice! HIL: squish instances of "(void) splhil()" and "(void) spl0();".	1996-02-14 02:43:54 +00:00
thorpej	b618522128	Make the DMA controller driver a little more new config-friendly. Still ... more work to do, but this is a step in the right direction.	1995-12-02 02:46:45 +00:00
cgd	132b41434c	new RCS ID format.	1994-10-26 07:22:45 +00:00
mycroft	c1e1831b84	Merge with 4.4-Lite.	1994-05-23 05:58:16 +00:00
mycroft	89a5de9e12	Most of the changes needed to make this continue to run.	1994-05-05 10:10:21 +00:00
mycroft	4862b84c92	Add RCS identifiers (this time on the correct side of the branch), and ... incorporate recent changes in netbsd-0-9 branch.	1993-08-01 19:22:24 +00:00
cgd	6dedb5151c	add hp300 kernel files. generic kernel files might need some help...	1993-05-13 13:56:20 +00:00
