I tried to disable the onboard graphics on my s2892:
device pci 6.0 off end
But that made it probe 6.1 - 6.7. Since the code only checks for multifunction devices at function 0, all of those responded. So now instead of disabling my card, it had 7 instances of it. I realize that the card probably shouldn't have responded to all of those functions, but it probably doesn't bother checking which function is addressed.
device pci 6.0 off end device pci 6.1 off end device pci 6.2 off end device pci 6.3 off end device pci 6.4 off end device pci 6.5 off end device pci 6.6 off end device pci 6.7 off end
This worked, but it is non-obvious. I wonder what the "right" way would be to handle this.
Is there any time when you want to disable function 0 but still have all the other functions enabled/probed?
Myles,
That seems like a defective card but something is strange. Why wouldn't it detect the functions when the first function was enabled?
A PCI cards functions don't have to be related to each other. It is legitimate to disable the first function and expect the others to work.
