Kernel/USB: Create controller base class and introduce USBManagement This removes Pipes dependency on the UHCIController by introducing a controller base class. This will be used to implement other controllers such as OHCI. Additionally, there can be multiple instances of a UHCI controller. For example, multiple UHCI instances can be required for systems with EHCI controllers. EHCI relies on using multiple of either UHCI or OHCI controllers to drive USB 1.x devices. This means UHCIController can no longer be a singleton. Multiple instances of it can now be created and passed to the device and then to the pipe. To handle finding and creating these instances, USBManagement has been introduced. It has the same pattern as the other management classes such as NetworkManagement. 2021-08-08 15:50:20 -03:00			`/*`
