2005-06-14back out SMM lockdown patch until some other solution is found.Theo de Raadt
SMM lockdown breaks apm on a few machines.
2005-05-29Lock SMM space on Intel E7xxx chipsets, too.Alexander Yurchenko
2005-05-29Remove debug printf I left.Alexander Yurchenko
2005-05-19Lock down SMM space on i82810 MCH and later chips in case BIOSAlexander Yurchenko
didn't it already for us. Reported by loic.duflot@sgdn.pm.gouv.fr via deraadt@. ok deraadt@ weingart@

2003-01-08do not match on via866 smbus controller; reported and tested by grange@Michael Shalayeff
2002-09-23For serverworks chipsets: instead of trying to prevent attaching the same busNathan Binkert
multiple times by restricting matches based on device id and revision, keep track of the bus numbers that were attached, and don't reattach them a second time. ok deraadt

2002-07-12support for the agp gart on various agp chipsets.Michael Shalayeff
only i810 driver was tested though. based on the netbsd's lkm, initially ported by hunter@dg.net.ua and later made into shape by mickey. testing by art@ and millert@ .

2002-05-10on ServerWorks CNB20HE Host:Michael Shalayeff
do not synthesyse secondary pci bus on the pchb0 rev 0x23 OR pchb1 w/ any revision. prompted by frisco@blackant.net in pr#2642
2002-05-06Try to deal with the pci shadow bus issue by disabling a specific chipNathan Binkert
revision of the CNB20HE that always seems to be involved in the shadow bus. This is definately not the right way to do things. The correct way is to try to figure out that the bus is being detected for the second time. ok deraadt
2002-04-28Machines with the Serverworks CNB20HE chipset also have a CIOB20 i/o bridge.Nathan Binkert
Instead of attaching pci busses to the CNB20HE, attach them to the CIOB20. This fixes problems where many of these machines will not attach a second pci bus. This also like Theo's previous diff prevents the shadow bus from appearing. Ok deraadt.

2000-04-10add support for true RNG presented on the i82802 FWH.Michael Shalayeff
it produces 1 byte at a time and has no ready irq, thus timeout driven. in fact w/ default hz=100 it produces up to 60% of gross entropy production in an average loaded desktop system.

1998-01-20Merge bus_dma support from NetBSD, mostly by Jason Thorpe. Only i386 uses itNiklas Hallqvist
so far, the other archs gets placeholders for now. I wrote a compatibility layer for OpenBSD's old isadma code so we can still use our old driver sources. They will however get changed to native bus_dma use, on a case by case basis. Oh yes, I almost forgot, I kept our notion of isadma being a device so DMA-less ISA-busses still work
