eeh	7539c8d1ce	Turn on PCI MEM and DMA.	2000-06-08 23:03:17 +00:00
cgd	cffb580806	Implement the more flexiable `evcnt' interface as discussed (briefly) on tech-kern and now documented in evcnt(9).	2000-06-04 19:14:14 +00:00
eeh	ca743bac9a	Use the PCI function code to distinguish simba bus A from bus B instead of the current hack.	2000-05-24 20:27:52 +00:00
mrg	651712a140	add a note about US IIi and PCI_INTERRUPT_LINE register	2000-05-17 09:25:58 +00:00
mrg	5b5f175f38	- store the ebus's parent so we can find the IOMMU - use generic iommu routines in the ebus code (uses the above) - add some more comments.	2000-04-08 04:33:09 +00:00
mrg	add6dbf96c	clean this up some.	2000-04-05 08:03:03 +00:00
eeh	186c3eba2b	Make pbrobeget() and probeset() work for 64-bit values as well. To do this the arguments are changed so the address is first and the ASI second so we can have the address in %o0:%o1 and not worry about unused registers. Also a bit of copyright cleanup.	1999-06-05 21:58:16 +00:00
mrg	da265ce045	clean up a bit, implement pci_conf_{read,write}() with probe[gs]et() (not yet used).	1999-06-05 05:29:50 +00:00
mrg	03adf4aad1	PCI driver for the UltraSPARC. this only works on the Ultra5/10 machines (`SUNW,sabre') for now, and it doesn't really quite work there yet anyway. the bus space/dma code is cloned from the sbus driver. the IOMMU code also is cloned from the sbus code, but separated out into iommu.c so that we can share it with the sbus driver. hopefully, much of the bus space/dma code can also be re-shared with the sbus driver and the ebus driver but for now these copies will do. support for the real UltraSPARC PCI (`SUNW,psycho') is unwritten, though most of this code is shared with it. we can probe PCI config space and try to configue devices, but interrupts don't work yet...	1999-06-04 13:42:14 +00:00
