See, that's the thing. I'm not seeing anything sent to probe that has Whole
set to true.
I'm using this code to check:
bool com_myCompany_driver_MyDriver::isWhole( IOService *object )
{
bool result = false;
OSBoolean *val = (OSBoolean*)(object->copyProperty("Whole",
gIOServicePlane));
if (val != NULL)
{
result = val->isTrue();
val->release();
}
return result;
}
