Hi Dave
As you may be aware dev -p command post linux kernel 2.6.25 fails with
"no PCI devices found on this system.". When I went through the kernel
a specific commit has removed pci_devices variable from the kernel code
==================================================================
git commit: 5ff580c10ec06fd296bd23d4570c1a95194094a0
by Greg Kroah-Hartman <gregkh(a)suse.de>
This is what he says in the commit
------------------------------------------------------------------------------------------------------------
This patch finally removes the global list of PCI devices. We are
relying entirely on the list held in the driver core now, and do not
need a separate "shadow" list as no one uses it.
------------------------------------------------------------------------------------------------------------
==================================================================
I saw some of your earlier postings where you have specifically mentioned about this
problem:
http://www.mail-archive.com/crash-utility@redhat.com/msg00346.html
With this I wanted to know, if you intend to keep dev -p behavior as it is now or
there is any plan to change it to display actual values?
Thank You

I (personally) have no plans to change it. If I remember correctly,
Bud Brown came up with an alternate scheme, but the imported data from
the kernel proper required to accomplish it was enormous (bordering
on absurd), so I suggested that it would be more appropriate as an
extension module.
Bud -- feel free to chime in here... ;-)
For that matter, even the "old" way required the import of ~1000 lines
of kernel #define's -- which always bugged me -- and was pretty much the
only crash command that had to do such a thing.
