I'm not exactly sure what you meant here. Do you mean the pci_readcfg calls? I thought they were low-level rather than compatibility.

It has been on the TODO list. If logging the ECC NMI (sans address) is sufficient, then the ECC NMI handler could be made generic and can be written/check-in in parallel with this effort. (In fact, I think that minimal patch should be done now.) Otherwise you have to install a more specific handler. In any case, I want to see Paul Saab's code. > There's a decision to be made here with regards to this code. > > If it's OK to relicense it under the BSDL, it should be integrated with > the i386 hostbridge code (ie. not a KLD at all).

Yuck, I hate dueling license issues but I guess I've signed up for this. I'll contact/work with Dan Hollis about this.

But I will send him a note. In fact, I'll copy him on this. thanks, Chris To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
