@sourcejedi @sima Yeah, no blog posts, just loads of lkml emails over the years, sorry.

That machine that randomly reassigned PCI ids at boot time is no longer with me, but it was great for testing. I'm sure you can do the same with virtual machines these days, passing in different virtual pci devices to them.

Persistent naming is for userspace to handle, the kernel just uses "grab the next free number" as it's naming "policy" as that's all it can really do.
