Your cpci controller should do this for you. Which driver are you using
for this?
thanks,

I'm using pci_hotplug.ko and cpci_hp_generic.ko..
I had to make some modifications to
cpci_hotplug_core.c :
I had to add this code in the check_slots function in
cpci_hotplug_core.c because the disable_slot function
wasn't called anywhere as part of
cpci_hotplug_slot_ops on the EXT event..:
list_for_each_entry(slot, &slot_list, slot_list){
if (slot->extracting) {
dbg("%s - calling disable for slot %s,slot->dev=%p",
__FUNCTION__,
slot->hotplug_slot->name,slot->dev);
disable_slot(slot->hotplug_slot);
}
}
i have this cpci controller according to lspci -vvv:
02:0c.0 PCI bridge: Intel Corporation 21154 PCI-to-PCI
Bridge (prog-if 00 [Normal decode])

Bridge: PM- B3+
meanwhile i found out that that the memory allocation
is also made wrong..I don't have reserved
non-prefetchable memory if i boot without any card
inserted and after that i try to insert a card..
so can someone tell me what is going wrong?
