Patch 3010de9850 changed the
documentation for the ipm_send() 'wait' parameter to something
that is not what the parameter does, and removed some helpful
ancillary information.

In 1.0 you could set only one callback on the whole gpio controller. It
was impossible for another sub-system to add another callback, without
overwritting an existing one.
Such API has been obsolete for a long time and no one is using it
anymore. Thus removing it entirely.

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.

The x86 architecture port is fitted with support for the unified kernel,
namely:
- the interrupt exit code now calls _Swap() if the current
thread is not a coop thread and if the scheduler is not locked
- there is no 'task' fields in the _nanokernel anymore: _Swap()
now calls _get_next_ready_thread instead
- the _nanokernel.fiber field is replaced by a more sophisticated
ready_q, based on the microkernel's priority-bitmap-based one
- nano_private includes nano_internal.h from the unified directory
- the FIBER, TASK and PREEMPTIBLE flags do not exist anymore: the thread
priority drives the behaviour
- the tcs uses a dlist for queuing in both ready and wait queues instead
of a custom singly-linked list
- other new fields in the tcs include a schedule-lock count, a
back-pointer to init data (when the task is static) and a pointer to
swap data, needed when a thread pending on _Swap() must be passed more
then just one value (e.g. k_stack_pop() needs an error code and data)
- fiberRtnValueSet() is aliased to _set_thread_return_value since it
also operates on preempt threads now
- _set_thread_return_value_with_data() sets the swap_data field in
addition to a return value from _Swap()
- convenience aliases are created for shorter names:
- _current is defined as _nanokernel.current
- _ready_q is defined as _nanokernel.ready_q
- _Swap() sets the threads's return code to -EAGAIN before swapping out
to prevent timeouts to have to set it (solves hard issues in some
kernel objects).
- Floating point support.
Note that, in _Swap(), the register holding the thread to be swapped in has
been changed from %ecx to %eax in both the legacy kernel and the unified kernel
to take advantage of the fact that the return value of _get_next_ready_thread()
is stored in %eax, and this avoids moving it to %ecx.

Dlc mtu has to be set by profile (before it returns dlc) which will be

Originally, x86 just supported APIC. Then later support
for the Mint Valley Interrupt Controller was added. This
controller is mostly similar to the APIC with some differences,
but was integrated in a somewhat hacked-up fashion.
Now we define irq_controller.h, which is a layer of abstraction
between the core arch code and the interrupt controller
implementation.
Contents of the API:
- Controllers with a fixed irq-to-vector mapping define
_IRQ_CONTROLLER_VECTOR_MAPPING(irq) to obtain a compile-time
map between the two.
- _irq_controller_program() notifies the interrupt controller
what vector will be used for a particular IRQ along with triggering
flags
- _irq_controller_isr_vector_get() reports the vector number of
the IRQ currently being serviced
- In assembly language domain, _irq_controller_eoi implements
EOI handling.
- Since triggering options can vary, some common defines for
triggering IRQ_TRIGGER_EDGE, IRQ_TRIGGER_LEVEL, IRQ_POLARITY_HIGH,
IRQ_POLARITY_LOW introduced.
Specific changes made:
- New Kconfig X86_FIXED_IRQ_MAPPING for those interrupt controllers
that have a fixed relationship between IRQ lines and IDT vectors.
- MVIC driver rewritten per the HAS instead of the tortuous methods
used to get it to behave like LOAPIC. We are no longer writing values
to reserved registers. Additional assertions added.
- Some cleanup in the loapic_timer driver to make the MVIC differences
clearer.
- Unused APIs removed, or folded into calling code when used just once.
- MVIC doesn't bother to write a -1 to the intList priority field since
it gets ignored anyway
