* config: Improve EDF SMP scheduler configurationSebastian Huber2019-12-195-7/+7
| | | | | | | | Use CONFIGURE_MAXIMUM_PROCESSORS to configure the EDF SMP scheduler context. This avoids hard to debug configuration errors resulting in memory corruptions. Close #3815.
* rtems: Simplify semaphore configurationSebastian Huber2019-12-113-3/+0
| | | | | | | | | | | | | | | The MrsP semaphore implementation predates the addition of self-contained synchronization objects. At this time, the potential memory reduction was justified considering the more complex configuration and additional use of the workspace. With the availability of self-contained synchronization options, e.g. POSIX mutexes, this is no longer justified. Memory constrained applications should use the self-contained synchronization objects. Remove the CONFIGURE_MAXIMUM_MRSP_SEMAPHORES configuration option. This has only an impact on applications which use SMP and a large number of scheduler instances. Update #3833.
* libtest: Change expected pass state stringSebastian Huber2019-12-055-5/+5

|
* score: Modify _Per_CPU_Perform_jobs()Sebastian Huber2019-05-201-0/+41
| | | | | | | | Process only the jobs initially registered on the processing list. This makes it possible to add jobs for the current processor in a job handler. These jobs are processed with the next SMP_MESSAGE_PERFORM_JOBS message. The lock is only acquired and released once.
* score: Add _Per_CPU_Add_job()Sebastian Huber2019-05-201-0/+43
|
* score: Simplify _SMP_Multicast_action()Sebastian Huber2019-05-201-10/+4
| | | | | | Move resposibility to disable thread dispatching to the caller of _SMP_Multicast_action(). Using an interrupt disable for this purpose is questionable.
* score: Add _SMP_Broadcast_action()Sebastian Huber2019-05-201-8/+32

* smpmulticast01: Use T_TEST_CASE()Sebastian Huber2019-05-201-22/+27
|
* score: More robust _SMP_Multicast_action()Sebastian Huber2019-04-122-7/+1
| | | | | | If the caller already disabled interrupts, then do not disable thread dispatching. Calling _SMP_Multicast_action() with interrupts disabled is a questionable use case.
* score: Improve _SMP_Multicast_action()Sebastian Huber2019-04-122-73/+127
| | | | Let it work during system initialization.
* score: Rework SMP multicast actionSebastian Huber2019-04-122-1/+7
| | | | | Use a FIFO list of jobs per processor to carry out the SMP multicast action. Use a done indicator per job to reduce the bus traffic a bit.
* score: Use processor mask in _SMP_Multicast_actionSebastian Huber2019-04-126-38/+386
| | | | Processor_mask is the internal data type to deal with processor sets.
* rtems: Add rtems_scheduler_get_processor_maximum()Sebastian Huber2019-04-0943-71/+86
| | | | | | | | | | | Add rtems_scheduler_get_processor_maximum() as a replacement for rtems_get_processor_count(). The rtems_get_processor_count() is a bit orphaned. Adopt it by the Scheduler Manager. The count is also misleading, since the processor set may have gaps and the actual count of online processors may be less than the value returned by rtems_get_processor_count(). Update #3732.
* rtems: Add rtems_scheduler_get_processor()Sebastian Huber2019-04-0931-115/+115
| | | | | | | | | | | Add rtems_scheduler_get_processor() as a replacement for rtems_get_current_processor(). The rtems_get_current_processor() is a bit orphaned. Adopt it by the Scheduler Manager. This is in line with the glibc sched_getcpu() function. Deprecate rtems_get_current_processor(). Update #3731.
* score: Fix plain priority thread queues (SMP)Sebastian Huber2019-02-071-0/+63
| | | | We must add/remove the priority queue to the FIFO of priority queues.
* build: Do not install test programsSebastian Huber2019-01-301-3/+1

* rtems: Allow to set ISR level 0 in SMP configSebastian Huber2019-01-091-1/+1
| | | | Update #3000.
* score: Fix per-CPU data allocationSebastian Huber2018-12-185-0/+117
| | | | | | | | | | | Allocate the per-CPU data for secondary processors directly from the heap areas before heap initialization and not via _Workspace_Allocate_aligned(). This avoids dependency on the workspace allocator. It fixes also a problem on some platforms (e.g. QorIQ) where at this early point in the system initialization the top of the RAM is used by low-level startup code on secondary processors (boot pages). Update #3507.

* Remove rtems_cache_*_processor_set() functionsSebastian Huber2018-11-261-45/+7
| | | | | | | | The following rtems_cache_*_processor_set() cache manager API functions are exotic, complex, very hard to use correctly, not used in the RTEMS code base, and apparently unused by applications. Close #3622.
* posix: Enable more smptests tests by defaultSebastian Huber2018-10-291-6/+0

* score: Remove CPU_PROVIDES_IDLE_THREAD_BODYSebastian Huber2018-10-052-12/+0
| | | | | | | Remove the CPU_PROVIDES_IDLE_THREAD_BODY option to avoid unnecessary conditional compilation. Close #3539.
* smp03: make printout match actual task nameDaniel Hellstrom2018-09-201-1/+1
|
* score: Add thread pin/unpin supportSebastian Huber2018-09-105-0/+679
| | | | | | | | | Add support to temporarily pin a thread to its current processor. This may be used to access per-processor data structures in critical sections with enabled thread dispatching, e.g. a pinned thread is allowed to block. Update #3508.
* score: Fix EDF SMP schedulerSebastian Huber2018-09-031-0/+24
| | | | | Fix a special case: block a one-to-one scheduled thread while having a non-empty affine ready queue on the same processor.
* bsps: bsp_start_on_secondary_processor()Sebastian Huber2018-07-251-2/+4
| | | | | | Pass current processor control as first parameter in bsp_start_on_secondary_processor() and qoriq_start_thread() to make dependency more explicit.

* score: Fix _Scheduler_EDF_SMP_Set_affinity()Sebastian Huber2018-07-185-0/+172
| | | | | | Commit 8744498752ad4f0eaf9fb5640c6a0e0f2dc92fda broke the _Scheduler_EDF_SMP_Set_affinity() implementation. We must test the overall affinity against the online processors.

* configure: Add subdir-objects to all automake flags.Chris Johns2018-04-111-1/+1
| | | | | | | | | | | This option silences warning with automake-1.16.1 allowing us to upgrade to that version. This change has been tested with automake-1.12.6 and automake-1.16.1. It seems version 1.16.1 configures slower than 1.12.6 for the same source and BSP. The newer versions is 6 second slower. Close #3387.

* Remove make preinstallChris Johns2018-01-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.
