Ugh. Almost two years ago, paulus promised me he was going to fix the slot name for rpaphp. Guess he didn't. This is one of the hateful things about the current design -- hotplug drivers do too much. Instead of being just the interface between the Linux PCI code and the hardware, they create sysfs directories, add files, and generally have far too much freedom. We have four different schemes currently for naming in slots/, 1. slot number. Used by cpqphp, ibmphp, acpiphp, pciehp, shpc. 2. domain:bus:dev:fn. Used by fakephp. 3a. domain:bus:dev. Used by rpaphp and sgihp. 3b. Except that rpaphp uses phy_location to present the information that should be in the name and sgihp uses path. ... I've forgotten what cpci uses. And yenta doesn't use it. How is anyone supposed to write sane managability tools in the presence of such anarchy? > ~ # cat /sys/bus/pci/slots/0000:00:02.2/phy_location > U787A.001.DNZ00Z5-P1-C2 Right. This should look like: # cat /sys/bus/pci/slots/U787A.001.DNZ00Z5-P1-C2/address 0000:00:02 -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
