Is there any concept of PCI domains in the kernel? This is for the DRM, while dealing with a complaint from Linus recently: > Please fix the fact that modern PCI is _not_ enumerated with just "bus, > slot, function". A lot of machines are starting to have a "domain number", > which allows fro multiple independent PCI subsystems in the same machine. > > On linux, you can use "pci_name(pdev)" to get a truly unique descriptor of > the device (within the PCI subsystem). It will look something like > > 0000:00:02.0 > > for "domain 0, bus 0, device 2, function 0". -- Eric Anholt eta@lclark.edu http://people.freebsd.org/~anholt/ anholt@FreeBSD.org
