| This changeset introduces a central device management system. The system comprises the following components: - kapi::devices::bus (type) A bus can be both a real (physically present inside the machine) or virtual (purely conceptual) bus. Busses form a hierarchy rooted in the virtual root_bus (accessible via `kapi::devices::get_root_bus`). Busses are derived from `kapi::devices::device`, and own devices. This means that a bus can be attached to another bus. This facilitates a uniform structure for device ownership. Each device needs to be attached to exactly one bus. Virtual devices, e.g. RAM disks, should be attached to the root root bus (via the `add_child` member function). Once a device, or bus, has been attached to a bus, it will be initialized (by means of a call to the `init` member function). Busses are responsible to initialize their children. If a bus has already been initialized, any newly attached children will automatically be initialized. During initialization, the `probe` member function of the bus under initialization weill be invoked. This allows a bus implementation to determine if the hardware, if any, is ready to be initialized and to also perform any required initialization steps. IMPORTANT: busses take ownership of their children in the form of a `unique_ptr`. - kapi::devices (namespace) The functions `allocate_major_number`, `register_device`, `unregister_device`, and `find_device` form the device manager. The device manager is responsible for keeping a record of active devices, allowing O(log n) lookup of devices by major and minor, and O(n) lookup by name. Additionally, the device manager is responsible for handing out major numbers (via `allocate_major_number`) and keeping track of active devices. When a child is attached to a bus, it will also automatically be registered with the device manager. Lookup of devices via the device manager can be achieved by means of either overload of `find_device`. Devices should never ask the manager directly for a major number. Instead, a controller should be used, which requests a major number per device "class" (as in kind, not language class). For example, a RAM disk controller may request a single major number for all RAM disks it is going to create. When the controller creates a new device of a given "class", e.g. a RAM disk, it should then supply that major number to the new device instance. IMPORTANT: the device manager does not own the active devices. Rather it holds a `flat_map` indexed by `pair{major, minor}` and resolving to `kstd::observer_ptr<device>`. - kstd::observer_ptr (type) An observer pointer is a simple vocabulary type to express the concept of having no ownership of the pointed-to object. In essence it is equivalent to a standard C-style pointer, but expresses semantics by virtue of being a separate type. | |||||
