* Enhance Semaphore Blocking and Readying Time Test CasesJoel Sherrill2014-07-1421-171/+477
| | | | | | | | | | | | | | | | tm02 and tm03 were modified to be reused for multiple configurations of RTEMS Classic API Semaphores. This added tm31-36. The messages for tm02 and tm03 were modified to indicate the semaphore attributes. tm31 - tm36 were added. This resulted in the following cases: tm02 - rtems_semaphore_obtain: Counting/FIFO not available caller blocks tm03 - rtems_semaphore_release: Counting/FIFO task readied preempts caller tm31 - rtems_semaphore_obtain: Counting/priority not available caller blocks tm32 - rtems_semaphore_release: Counting/priority task readied preempts caller tm33 - rtems_semaphore_obtain: Binary/FIFO not available caller blocks tm34 - rtems_semaphore_release: Binary/FIFO task readied preempts caller tm35 - rtems_semaphore_obtain: Binary/priority not available caller blocks tm36 - rtems_semaphore_release: Binary/priority task readied preempts caller
* score: Implement forced thread migrationSebastian Huber2014-05-071-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation of task migration in RTEMS has some implications with respect to the interrupt latency. It is crucial to preserve the system invariant that a task can execute on at most one processor in the system at a time. This is accomplished with a boolean indicator in the task context. The processor architecture specific low-level task context switch code will mark that a task context is no longer executing and waits that the heir context stopped execution before it restores the heir context and resumes execution of the heir task. So there is one point in time in which a processor is without a task. This is essential to avoid cyclic dependencies in case multiple tasks migrate at once. Otherwise some supervising entity is necessary to prevent life-locks. Such a global supervisor would lead to scalability problems so this approach is not used. Currently the thread dispatch is performed with interrupts disabled. So in case the heir task is currently executing on another processor then this prolongs the time of disabled interrupts since one processor has to wait for another processor to make progress. It is difficult to avoid this issue with the interrupt latency since interrupts normally store the context of the interrupted task on its stack. In case a task is marked as not executing we must not use its task stack to store such an interrupt context. We cannot use the heir stack before it stopped execution on another processor. So if we enable interrupts during this transition we have to provide an alternative task independent stack for this time frame. This issue needs further investigation.
* testsuite: Add a per BSP test check for tests not to build.Chris Johns2014-05-051-3/+3
| | | | | | | | Provide a file per BSP to list tests that do not build for a BSP. This change removes the BSP_SMALL_MEMORY hack from the code. That hack was a mistake. Provide configuration files for each BSP with tests that cannot build.
* score: Static scheduler configurationSebastian Huber2014-04-152-22/+29
| | | | | | Do not allocate the scheduler control structures from the workspace. This is a preparation step for configuration of clustered/partitioned schedulers on SMP.
* rtems: Rename rtems_smp_get_processor_count()Sebastian Huber2014-04-111-1/+1
| | | | | | Rename rtems_smp_get_processor_count() in rtems_get_processor_count(). Make rtems_get_processor_count() a function in uni-processor configurations to enable ABI compatibility with SMP configurations.

* score: Add scheduler control to scheduler opsSebastian Huber2014-04-042-6/+12
| | | | | Scheduler operations must be free of a global scheduler context to enable partitioned/clustered scheduling.
* score: Move priority bit map to scheduler instanceSebastian Huber2014-04-032-24/+18
| | | | | | Delete global variables _Priority_Major_bit_map and _Priority_Bit_map. This makes it possible to use multiple priority scheduler instances for example with clustered/partitioned scheduling on SMP.

* score: Add local context to SMP lock APISebastian Huber2014-03-111-3/+3
| | | | | | | | | | | Add a local context structure to the SMP lock API for acquire and release pairs. This context can be used to store the ISR level and profiling information. It may be later used to enable more sophisticated lock algorithms, e.g. MCS locks. There is only one lock that cannot be used with a local context. This is the per-CPU lock since here we would have to transfer the local context through a context switch which is very complicated.

* smp: Add and use _Assert_Owner_of_giant()Sebastian Huber2013-08-302-27/+87
| | | | | | | | | | | | | | Add and use _ISR_Disable_without_giant() and _ISR_Enable_without_giant() if RTEMS_SMP is defined. On single processor systems the ISR disable/enable was the big hammer which ensured system-wide mutual exclusion. On SMP configurations this no longer works since other processors do not care about disabled interrupts on this processor and continue to execute freely. On SMP in addition to ISR disable/enable an SMP lock must be used. Currently we have only the Giant lock so we can check easily that ISR disable/enable is used only in the right context.
* score: Per-CPU thread dispatch disable levelSebastian Huber2013-08-092-17/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a per-CPU thread dispatch disable level. So instead of one global thread dispatch disable level we have now one instance per processor. This is a major performance improvement for SMP. On non-SMP configurations this may simplifiy the interrupt entry/exit code. The giant lock is still present, but it is now decoupled from the thread dispatching in _Thread_Dispatch(), _Thread_Handler(), _Thread_Restart_self() and the interrupt entry/exit. Access to the giant lock is now available via _Giant_Acquire() and _Giant_Release(). The giant lock is still implicitly acquired via _Thread_Dispatch_decrement_disable_level(). The giant lock is only acquired for high-level operations in interrupt handlers (e.g. release of a semaphore, sending of an event). As a side-effect this change fixes the lost thread dispatch necessary indication bug in _Thread_Dispatch(). A per-CPU thread dispatch disable level greatly simplifies the SMP support for the interrupt entry/exit code since no spin locks have to be acquired in this area. It is only necessary to get the current processor index and use this to calculate the address of the own per-CPU control. This reduces the interrupt latency considerably. All elements for the interrupt entry/exit code are now part of the Per_CPU_Control structure: thread dispatch disable level, ISR nest level and thread dispatch necessary. Nothing else is required (except CPU port specific stuff like on SPARC).

| | | | | | | | | This commit deletes all RTEMS ChangeLog files. These files have been abandoned since converting to git version control. The historical data may be recovered by checking out any commit before this one. Most of the contents of these ChangeLog files can also be found in the git log.
