unified: initial unified kernel implementation Summary of what this includes: initialization: Copy from nano_init.c, with the following changes: - the main thread is the continuation of the init thread, but an idle thread is created as well - _main() initializes threads in groups and starts the EXE group - the ready queues are initialized - the main thread is marked as non-essential once the system init is done - a weak main() symbol is provided if the application does not provide a main() function scheduler: Not an exhaustive list, but basically provide primitives for: - adding/removing a thread to/from a wait queue - adding/removing a thread to/from the ready queue - marking thread as ready - locking/unlocking the scheduler - instead of locking interrupts - getting/setting thread priority - checking what state (coop/preempt) a thread is currenlty running in - rescheduling threads - finding what thread is the next to run - yielding/sleeping/aborting sleep - finding the current thread threads: - Add operationns on threads, such as creating and starting them. standardized handling of kernel object return codes: - Kernel objects now cause _Swap() to return the following values: 0 => operation successful -EAGAIN => operation timed out -Exxxxx => operation failed for another reason - The thread's swap_data field can be used to return any additional information required to complete the operation, such as the actual result of a successful operation. timeouts: - same as nano timeouts, renamed to simply 'timeouts' - the kernel is still tick-based, but objects take timeout values in ms for forward compatibility with a tickless kernel. semaphores: - Port of the nanokernel semaphores, which have the same basic behaviour as the microkernel ones. Semaphore groups are not yet implemented. - These semaphores are enhanced in that they accept an initial count and a count limit. This allows configuring them as binary semaphores, and also provisioning them without having to "give" the semaphore multiple times before using them. mutexes: - Straight port of the microkernel mutexes. An init function is added to allow defining them at runtime. pipes: - straight port timers: - amalgamation of nano and micro timers, with all functionalities intact. events: - re-implementation, using semaphores and workqueues. mailboxes: - straight port message queues: - straight port of microkernel FIFOs memory maps: - straight port workqueues: - Basically, have all APIs follow the k_ naming rule, and use the _timeout subsystem from the unified kernel directory, and not the _nano_timeout one. stacks: - Port of the nanokernel stacks. They can now have multiple threads pending on them and threads can wait with a timeout. LIFOs: - Straight port of the nanokernel LIFOs. FIFOs: - Straight port of the nanokernel FIFOs.
