2017-04-05SMP: Simplify SMP multicast actionsSebastian Huber4-63/+85
2017-03-28arm: Optimize context switchSebastian Huber3-78/+55
Set CPU_ENABLE_ROBUST_THREAD_DISPATCH to TRUE. In this case the interrupts are always enabled during a context switch even after interrupt processing (see #2751). Remove the CPSR from the context control since it contains only volatile bits. Close #2954.
2017-03-09arm: Fix CPU context validation for Cortex-R4Sebastian Huber2-7/+3
Do not touch the FPSCR[QC] bit since this is DNM/RAZ on Cortex-R4.
2017-03-08arm: Remove legacy execption supportSebastian Huber4-301/+0
2017-03-07score: Fix scheduler yield in SMP configurationsSebastian Huber4-20/+46
Check that no ask help request is registered during unblock and yield scheduler operations. There is no need to ask for help if a scheduled thread yields, since this is already covered by the pre-emption detection. Update #2556.

2017-02-03score: Move _Thread_Scheduler_ask_for_help()Sebastian Huber3-36/+34
Move _Thread_Scheduler_ask_for_help(), rename it to _Thread_Ask_for_help() and make it static.
2017-02-03score: Improve scheduler helping protocolSebastian Huber22-169/+88
Only register ask for help requests in the scheduler unblock and yield operations. The actual ask for help operation is carried out during _Thread_Do_dispatch() on a processor related to the thread. This yields a better separation of scheduler instances. A thread of one scheduler instance should not be forced to carry out too much work for threads on other scheduler instances. Update #2556.
2017-02-03sparc: Fix volatile clobberSebastian Huber1-1/+1
Do not adjust the stack pointer, since this is already done by the restor instruction. Update #2270.
2017-01-31score: Add _Thread_queue_Object_nameSebastian Huber18-56/+130
Add the special thread queue name _Thread_queue_Object_name to mark thread queues embedded in an object with identifier. Using the special thread state STATES_THREAD_QUEUE_WITH_IDENTIFIER is not reliable for this purpose since the thread wait information and thread state are protected by different SMP locks in separate critical sections. Remove STATES_THREAD_QUEUE_WITH_IDENTIFIER. Add and use _Thread_queue_Object_initialize(). Update #2858.

Close #2890.
2017-01-30bsps/arm: Fix Cortex-M DWT CPU counter.Christian Mauderer1-1/+45
It is necessary to enable the DWT using a special initialization sequence before the CYCCNT can be enabled. See for example the RESET_CYCLE_COUNTER in libbsp/arm/atsam/utils/utility.h. Note that this problem only occurs if no debugger is connected. A debugger most likely already enables the necessary module.
2017-01-27score: Clarify _Heap_Extend()Sebastian Huber1-5/+6
Update #1747.
2017-01-27score: Fix typoSebastian Huber1-1/+1
2017-01-26score: Fix user extensions orderSebastian Huber3-15/+26
Use forward and reverse order for initial and dynamic extensions. This is the behaviour documented in the C Users Guide. Change thread terminate order to backward to be in line with the thread delete order. Change fatal error order to forward to ensure that initial extensions are called first due the peculiar execution context of fatal error extensions, see _Terminate() documentation. Update #2692.
2017-01-26score: Delete _CPU_Context_Fp_start()Sebastian Huber18-288/+14
Since the FP area pointer is passed by reference in _CPU_Context_Initialize_fp() the optional FP area adjustment via _CPU_Context_Fp_start() is superfluous. It is also wrong with respect to memory management, e.g. pointer passed to _Workspace_Free() may be not the one returned by _Workspace_Allocate(). Close #1400.

2017-01-24Remove CPU_BIG_ENDIAN and CPU_LITTLE_ENDIANSebastian Huber17-310/+0
Use de-facto standard BYTE_ORDER instead. Close #2803.
2017-01-13posix: shared memory supportGedare Bloom2-2/+4
Add POSIX shared memory manager (Shm). Includes a hook-based approach for the backing memory storage that defaults to the Workspace, and a test is provided using the heap. A test is also provided for the basic use of mmap'ing a shared memory object. This test currently fails at the mmap stage due to no support for mmap.

2017-01-12score: Replace STATES_DELAYINGSebastian Huber1-37/+6
Replace STATES_DELAYING with STATES_WAITING_FOR_TIME. There is no need for separate timeout thread states. The Thread_Control::Timer::header and Watchdog_Control::cpu members can be used to figure out the kind of timeout.

2017-01-11score: Improve SMP lock debug supportSebastian Huber4-7/+18
The CPU index starts with zero. Increment it by one, to allow global SMP locks to reside in the BSS section.
