* Temporarily disable libdl for lm32Joel Sherrill2015-03-061-1/+4
| | | | | | | There is a GCC ICE when building libdl. This temporarily disables building libdl until that is resolved. updates 2283.
* Temporarily disable libdl for v850Joel Sherrill2015-03-061-1/+4
| | | | | | | | | There is an issue linking dl0* which has not been resolved. This issue is being tracked but is not considered a release blocker. This patch is a workaround which disables libdl for the v850 until the ticket is resolved. updates 2260.

* score: Implement fine-grained locking for eventsSebastian Huber2015-03-0512-221/+205
| | | | | | | Use the ISR lock of the thread object to protect the event state and use the Giant lock only for the blocking operations. Update #2273.

| | | | Update #2273.
* score: Add ISR lock to Objects_ControlSebastian Huber2015-03-055-0/+166
| | | | | | | | | This enables per-object SMP locks on SMP configurations and is the first step to support fine-grained locking. On uni-processor configuration there will be no overhead. The _Objects_Acquire() is intended to replace _Objects_Get_isr_disable(). Update #2273.
* score: Thread dispatch dis/enable without GiantSebastian Huber2015-03-051-22/+82
| | | | Update #2273.
* score: Add and use _Thread_Do_dispatch()Sebastian Huber2015-03-053-85/+120
| | | | | | | | | | | | The _Thread_Dispatch() function is quite complex and the time to set up and tear down the stack frame is significant. Split this function into two parts. The complex part is now in _Thread_Do_dispatch(). Call _Thread_Do_dispatch() in _Thread_Enable_dispatch() only if necessary. This increases the average case performance. Simplify _Thread_Handler() for SMP configurations. Update #2273.
* score: Simplify and fix signal deliverySebastian Huber2015-03-054-52/+26
| | | | | | | Deliver the POSIX signals after the thread state was updated to avoid race-conditions on SMP configurations. Update #2273.
* score: Update _Thread_Heir only if necessarySebastian Huber2015-03-0511-75/+49
| | | | | | | | | | | | | | | | | | | | Previously, the _Thread_Heir was updated unconditionally in case a new heir was determined. The _Thread_Dispatch_necessary was only updated in case the executing thread was preemptible or an internal thread was unblocked. Change this to update the _Thread_Heir and _Thread_Dispatch_necessary only in case the currently selected heir thread is preemptible or a dispatch is forced. Move the schedule decision into the change priority operation and use the schedule operation only in rtems_task_mode() in case preemption is enabled or an ASR dispatch is necessary. This is a behaviour change. Previously, the RTEMS_NO_PREEMPT also prevented signal delivery in certain cases (not always). Now, signal delivery is no longer influenced by RTEMS_NO_PREEMPT. Since the currently selected heir thread is used to determine if a new heir is chosen, non-preemptible heir threads currently not executing now prevent a new heir. This may have an application impact, see change test tm04. Document this change in sp04. Update #2273.

| | | | | | | | | | Empty structures are implementation-defined in C. GCC gives them a size of zero. In C++ empty structures have a non-zero size. Add ISR_LOCK_DEFINE() to define ISR locks for structures used by C and C++. Update #2273.

| | | | | | | | In _ARMV4_Exception_fiq_default, set the F bit of the SPSR so that when it gets loaded back to the CPSR in save_more_context it won't re-enable the FIQs. Tested on a TMS570LS3137.
* posix: fix error return code for pthread_mutex_trylockGedare Bloom2015-02-251-1/+4
| | | | | | | | | pthread_mutex_trylock() should return EBUSY if the mutex is already locked. The translations of CORE_MUTEX_STATUS_NESTING_NOT_ALLOWED is EDEADLK which is correct for pthread_mutex_lock(). This fixes the translation for trylock. Closes #2170.
* Panic on RTEMS_FAST_MUTEX network semaphore claim/release.Chris Johns2015-02-241-1/+8
| | | | | | | Fix the code to panic rather than perform a bad access if the network semaphore is accessed without the stack being intialised. Closes #2229.
