Hi,

could somebody explain what determines when in the sequence of hot
unplugging pci_disable_device() is called?

Regards
Oliver

I don't know the answer, but you might have better luck cc'ing
the linux-pci list too.

I'm not positive about this, but pci_disable_device() should be called
as part of the device's driver's .remove method, which is called from
the sequence:

hotplug driver ->
pci_remove_bus_device() ->
pci_destroy_dev() ->
pci_stop_dev() ->
device_unregister()

- R.

When a pci device is hot unplugged, .remove callback of the
corresponding adapter card driver. It calls pci_disable_device().
