SubjectRe: Allocating uge chunks of kernel memory
> Where might I find the "biphysarea" patch? (I'm using 2.0.32.)

The URL I have is

http://www.uni-paderborn.de/fachbereich/AG/heiss/linux/bigphysarea.html

though it doesn't seem to answer at the moment. I can send it
to you by mail if need be. It's an improved version of the
original patch by Matt Welsh, available under

ftp://ftp.cs.cornell.edu/pub/mdw/

If you want to move to a scatter-gather scheme at some point,
one PCI-to-generic-bus chip that's very pleasant is the PLX9080
(www.plxtech.com). We switched from the AMCC part for just
this reason.

Another option is to have an RT-Linux process poll the AMCC
DMA controller to reissue transfers when needed, provided
your board can buffer at least a few hundred microseconds
of data. (http://luz.cs.nmt.edu/~rtlinux/)
