| H A D | subr_kobj.c | diff 121129 Thu Oct 16 07:16:28 MDT 2003 dfr * Add multiple inheritance to kobj. Each class can have zero or more base classes and if a method is not found in a given class, its base classes are searched (in the order they were declared). This search is recursive, i.e. a method may be define in a base class of a base class. * Change the kobj method lookup algorithm to one which is SMP-safe. This relies only on the constraint that an observer of a sequence of writes of pointer-sized values will see exactly one of those values, not a mixture of two or more values. This assumption holds for all processors which FreeBSD supports. * Add locking to kobj class initialisation. * Add a simpler form of 'inheritance' for devclasses. Each devclass can have a parent devclass. Searches for drivers continue up the chain of devclasses until either a matching driver is found or a devclass is reached which has no parent. This can allow, for instance, pci drivers to match cardbus devices (assuming that cardbus declares pci as its parent devclass). * Increment __FreeBSD_version. This preserves the driver API entirely except for one minor feature used by the ISA compatibility shims. A workaround for ISA compatibility will be committed separately. The kobj and newbus ABI has changed - all modules must be recompiled. |
