Subject: Kernel support for hot-plugging PCI adapters

Any plans to add support or is there support in the 2.4 kernel for
hot-plugging a PCI adapter? It may be in the sources already, but I can't
seem to locate it. Any help would be appreciated.

Thanks,
Duane Grigsby

For devices, the support is already there. See Documentation/pci.txt.
Look for 'probe', 'id_table', etc.

I don't think there is support in the current tree for a controller that
supports physical hotplugging of PCI adapters, yet. Compaq has a driver
outside the tree to do such a thing (needing only very minor kernel
patches), see http://opensource.compaq.com
