Re: Re: How to route INTA interupt on pci to IRQ after hotplug??

[florea igor <fl_igor@yahoo.com>]

 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])
        Control: I/O+ Mem+ BusMaster+ SpecCycle-

                Status: D0 PME-Enable- DSel=0 DScale=0
PME-
                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?
