Combination trait that boards provide to the kernel that includes all of the extensible operations the kernel supports.

This is the primary method for configuring the kernel for a specific board.

Required Associated Types

type SyscallDriverLookup: SyscallDriverLookup

The implementation of the system call dispatch mechanism the kernel will use.

type SyscallFilter: SyscallFilter

The implementation of the system call filtering mechanism the kernel will use.

type ProcessFault: ProcessFault

The implementation of the process fault handling mechanism the kernel will use.

type ContextSwitchCallback: ContextSwitchCallback

The implementation of the context switch callback handler the kernel will use.

type Scheduler: Scheduler<C>

The implementation of the scheduling algorithm the kernel will use.

type SchedulerTimer: SchedulerTimer

The implementation of the timer used to create the timeslices provided to applications.

type WatchDog: WatchDog

The implementation of the WatchDog timer used to monitor the running of the kernel.
