- No more distinction between i/o-mapped and memory-mapped devices. It's all "bus space" now, and space tags differentiate the space with finer grain than the bus chipset tag. - Add memory barrier methods. - Implement space alloc/free methods. - Implement region read/write methods (like memcpy to/from bus space). This interface provides a better abstraction for dealing with machine-independent chipset drivers. |

$NetBSD: README,v 1.2 1994/10/27 04:21:29 cgd Exp $ This directory contains files which are used during PCI configuration and PCI device drivers. Eventually, most of the device drivers and some of the configuration support should become machine-independent and be moved to a more general location. The configuration support was implemented according to the `PCI Local Bus Specification, Production Version, Revision 2.0' dated April 30, 1993. Section numbers referred to in the code may be specific to that edition of the specification. Some attempt has been made to insure that the code works on rogue machines where the BIOS doesn't do its job, but in general I can't guarantee that. -- - Charles Hannum NetBSD group August 8, 1994
