Now that I can actually boot the machine, I could test and send my patch upstream for Blackbird support in skiboot<\/a>. One thing I noticed with the current firmware from Raptor<\/a> is that the PCIe slot names were wrong. While a pretty minor point, it’s a bit funny that there’s only two slots and the names were wrong.<\/p>\n\n\n\n

The PCIe slot names are used to call out the physical location of PCIe cards in the system, so if you, say, hit a bunch of errors, OS\/firmware can say “It’s this card in the slot labeled BLAH on the board”.<\/p>\n\n\n\n

With my patch, the slot table from skiboot is spat out looking like this:<\/p>\n\n\n\n

If you want to give it a go, grab the patch, build skiboot, and flash it on. Alternatively, you can download a built skiboot here<\/a>. To flash it, do this:<\/p>\n\n\n\n
# Copy to your BMC for the Blackbird\nscp skiboot-v6.5-146-g376bed3f.lid.xz.stb root@blackbird:\/tmp\/\n\n# then, ssh to the BMC\n$ ssh root@blackbird\n\n# ensure the machine is off\nobmcutil poweroff --wait\n\n# Now, make a backup copy (remember to copy it off \/tmp on the bmc)\npflash -P PAYLOAD -r \/tmp\/skiboot-backup\n\n# and flash the new skiboot:\npflash -e -P PAYLOAD -p \/tmp\/skiboot.lid.xz.stb\n\n# now, power on the box\nobmcutil poweron<\/pre>\n\n\n\n
