Hello, I have written a bus device driver which itself is a pci driver. Child devices may allocate resources from my bus device.
My bus device does the usual management of resources through the children's ivars. My question is this: The bus device mallocs the children's ivars in bus_add_child and frees the ivars in either bus_detach or bus_child_detached. The children are added in identify methods through BUS_ADD_CHILD. As I understand the code the bus device's bus_child_detached method is called in device_delete_child only if the child device is already attached. So, there seems to be a memory leak if I delete the child device in either identify or probe. My current solution (not tested yet) is to explicitly call BUS_CHILD_DETACHED in the child device's code before calling device_delete_child. Is this the correct way or is there a more elegant/cleaner solution? I expected to find something like a BUS_DELETE_CHILD method. Thank you for any advice, Norbert Koch _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
