adding driver personalities dynamically

Hello,

I am porting a pci driver to macosx that supports a very large number of
devices. This list of devices is configurable on other os's and we want to
maintain that behaviour on macosx (meaning we want to not use the
info.plist to do our matching). So i have found the IOCatalogue's
functions: addDrivers and removeDrivers, but unfortunately I don't seem to
be getting matched to my devices (i have successfully tried hardcoding the
info into the info.plist).

this is the general idea of what i do for adding....

OSArray * personalityArray = OSArray::withCapacity(1);
OSString * ioClass = OSString::withCString("my_pci_driver_class_name");
OSString * ioProvider = OSString::withCString("IOPCIDevice");

// create a personality for the device
OSDictionary * personality = OSDictionary::withCapacity(3);
OSString * ioPCIMatch = OSString::withCString("DDDDVVVV DDDDVVVV");
// if i wanted to match against two different devices

personality->setObject("IOClass", ioClass);
personality->setObject("IOProviderClass", ioProvider);
personality->setObject("IOPCIPrimaryMatch", ioPCIMatch);

// append personality to end of array
personalityArray->setObject(personality);

bool result = gIOCatalogue->addDrivers(personalityArray, false);

// clean up
personalityArray->release();
personality->release();
ioClass->release();
ioProvider->release();
ioPCIMatch->release();


now i have tried passing true in the above call to addDrivers but that
didn't seem to work (by the way addDrivers has been returning true). So
then i came up
with calling gIOCatalogue->startMatching() like so...

OSDictionary * personality = OSDictionary::withCapacity(1);
OSString * ioProvider = OSString::withCString("IOPCIDevice");
personality->setObject("IOProviderClass", ioProvider);

bool result = startMatching(personality);

ioProviderClass->release();
personaltiy->release();

So anyway, even though i think i am doing everything right (a foolish
assumption indeed) i am not getting my device to match against my driver.
Does anyone have experience using these calls successfully? Or is there a
better way to get around this problem of needing to have dynamic device
matching personalities?

Thanks

Aaron
