However, it is explained only in the section about ISA resource allocation in the developers handbook. Developers looking for information about DMA for PCI cards miss this very useful information. It should possibly be put into its own topic. >How-To-Repeat: read http://www.freebsd.org/doc/en/books/developers-handbook/isa-driver-busmem.html >Fix: Create a topic documenting bus_dma? >Release-Note: >Audit-Trail: From: Hiten Pandya To: bug-followup@FreeBSD.ORG Cc: Subject: Re: docs/54752 [ bus_dma ] Date: Sat, 6 Sep 2003 11:00:07 -0700 Bruce, This is a good idea, and it has been discussed before, somewhere but I am not sure where exactly. Anyway, the bus_dma information in the ISA section is old. I have plans to write a bus_dma chapter for the Developer's Handbook ,but not anytime soon as I am busy with College and what not. If you want, you can write a chapter for the Developer's Handbook which documents the bus_dma subsyste -- you can get all the information you need for this from the bus_dma(9) manual page.
