Vincenzo Frascino	bb9c8df891	arm: core: Update core to use struct k_thread This patch updates the ARM core to use struct k_thread instead of struct tcs. Struct tcs has been deprecated with Zephyr 1.6. Change-Id: I1219add0bbcca4b963ffe02cd4519eca355c7719 Signed-off-by: Vincenzo Frascino <vincenzo.frascino@linaro.org>	8 years ago

David B. Kinder	ac74d8b652	license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

Benjamin Walsh	f6ca7de09c	kernel/arch: consolidate tTCS and TNANO definitions There was a lot of duplication between architectures for the definition of threads and the "nanokernel" guts. These have been consolidated. Now, a common file kernel/unified/include/kernel_structs.h holds the common definitions. Architectures provide two files to complement it: kernel_arch_data.h and kernel_arch_func.h. The first one contains at least the struct _thread_arch and struct _kernel_arch data structures, as well as the struct _callee_saved and struct _caller_saved register layouts. The second file contains anything that needs what is provided by the common stuff in kernel_structs.h. Those two files are only meant to be included in kernel_structs.h in very specific locations. The thread data structure has been separated into three major parts: common struct _thread_base and struct k_thread, and arch-specific struct _thread_arch. The first and third ones are included in the second. The struct s_NANO data structure has been split into two: common struct _kernel and arch-specific struct _kernel_arch. The latter is included in the former. Offsets files have also changed: nano_offsets.h has been renamed kernel_offsets.h and is still included by the arch-specific offsets.c. Also, since the thread and kernel data structures are now made of sub-structures, offsets have to be added to make up the full offset. Some of these additions have been consolidated in shorter symbols, available from kernel/unified/include/offsets_short.h, which includes an arch-specific offsets_arch_short.h. Most of the code include offsets_short.h now instead of offsets.h. Change-Id: I084645cb7e6db8db69aeaaf162963fe157045d5a Signed-off-by: Benjamin Walsh <benjamin.walsh@windriver.com>	9 years ago
Allan Stephens	4aef71b9f6	unified: Finish adding thread monitoring support Existing code wasn't removing a thread from the kernel's list of active threads if the thread terminated or aborted. (It did remove it if the delayed starting of a thread was cancelled.) Change-Id: Icc97917e33765696480d0e9bf31e882ef555d095 Signed-off-by: Allan Stephens <allan.stephens@windriver.com>	9 years ago
Benjamin Walsh	b4b108de4d	unified: rename sched.h to ksched.h Build breaks when enabling CONFIG_NEWLIB_LIBC because it has its own sched.h file. This is a bad symptom of a greater issue: the build system passes many '-I<path>' options to the compiler, and that allows including header files by simply specifying their names (when located somewhere else than <zephyr>/include/) and can cause clashes when several files in different locations have the same name, like in this case. Fixes ZEP-1062. Change-Id: I81d1d69ee6669a609cd0c420b1b8f870d17dcb67 Signed-off-by: Benjamin Walsh <benjamin.walsh@windriver.com>	9 years ago
Benjamin Walsh	3cf3778d31	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).
