Hi Greg, Alex
This patchset adds an uevent framework to pci_hotplug.
Why?
What is this needed for?
Who is going to use this?
Now there is no hotplug management utility as far as I know.
Not true, I know of at least 2 for PCI, one opensource and one not.
I think such utility is necessary for system administrators and
the hotplug event notification is useful for it.
Nope, its not necessary.
Do you mean utility doesnt need to handle hotplug events, or
utility can handle events without notification mechanism?
BTW, IIRC, PCI hotplug core used to have a event notification
mechanism using sysfs_update_file(*) and some people (maybe
including you) tried to utilize it in the userland ulitity (
pcihputil?). But it seems to have been given up. If you know
about that, could you tell me what the problem was?
(*) sysfs_update_file() had been removed from the kernel.
Thanks,
Kenji Kaneshige
