unified/arm: add unified kernel support for ARM arch The ARM architecture port is fitted with support for the unified kernel, namely: - the interrupt/exception exit code now pends PendSV if the current thread is not a coop thread and if the scheduler is not locked - fiber_abort is replaced by k_thread_abort(), which takes a thread ID as a parameter (i.e. does not only operate on the current thread) - the _nanokernel.flags cache of _current.flags is not used anymore (could be a source of bugs) and is not needed in the scheduling algo - there is no 'task' field in the _nanokernel anymore: PendSV not 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 - thread initialization initializes new fields in the tcs, and does not initialize obsolete ones - 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) - the 'fiber' and 'task' fields of _nanokernel are replaced with an O(1) ready queue (taken from the microkernel) - 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).

ccflags-y += -I$(srctree)/kernel/unified/include
Use ccflags-y and asflags-y instead of EXTRA_CFLAGS According to section 3.7 of Documentation/kbuild/makefiles.txt, using EXTRA_CFLAGS in Makefiles is "still supported but their usage is deprecated." However, using make EXTRA_CFLAGS="-DSOMETHING" results in EXTRA_CFLAGS from Makefiles being overwritten, obviously breaking the build. This patch converts to them to the newer ccflags-y which also fixes the problem. Change-Id: I6309439599d4c9cc184f9ecd941bde841982ef07 Signed-off-by: Anas Nashif <anas.nashif@intel.com>

nanokernel: support GCC compiler atomic builtins Arches now select whether they want to use the GCC built-ins, their own assembly implementation, or the generic C code. At the moment, the SDK compilers only support builtins for ARM and X86. ZEP-557 opened to investigate further.

irq_offload: API to run a function in IRQ context Software interrupts or system calls aren't really appropriate for zephyr, but we have an ongoing need in our test code to run a function with arguments synchronously in interrupt context. This patch introduces irq_offload() which allows us to do this without separate initialization or having to manage fake IRQs in the interrupt controller. ARM assembly code contributed by Benjamin Walsh <benjamin.walsh@windriver.com> ARC is not yet implemented but will be in a subsequent patch. irq_test_common.h has been removed and all test cases updated to use the new API.
