* score: Simplify _Scheduler_Tick()Sebastian Huber2021-08-121-4/+22
| | | | | | | | | | | | | | | | | | The NULL pointer check for the executing thread was introduced by commit: commit be3c257286ad870d8d1a64941cde53fd2d33a633 Author: Sebastian Huber <sebastian.huber@embedded-brains.de> Date: Thu Jun 5 11:17:26 2014 +0200 score: Avoid NULL pointer access Check that the executing thread is not NULL in _Scheduler_Tick(). It may be NULL in case the processor has an optional scheduler assigned and the system was not able to start the processor. However, it is no longer necessary since now the clock interrupt is distributed to the online processors.
* score: Replace priority prepend it with an enumSebastian Huber2021-08-121-2/+10
| | | | | | | | Use the new Priority_Group_order enum instead of a boolean to indicated if a priority should be inserted as the first or last node into its priority group. This makes the code more expressive. It is also a bit more efficient since a branch in _Scheduler_Node_set_priority() is avoided and a simple bitwise or operation can be used.
* Return status code for _Scheduler_Set_affinity()Sebastian Huber2021-04-271-9/+18
| | | | | This avoids having conditional statements to get the API-specific status code.
* rtems: Change rtems_task_get_affinity() statusSebastian Huber2021-04-271-1/+1
| | | | | | | | | In case the processor set is not large enough to contain the processor affinity set of the task return RTEMS_INVALID_SIZE instead of RTEMS_INVALID_NUMBER. This is more in line with other directives since the issue is related to the size of an object. Close #4393.
* Return status code for _Scheduler_Get_affinity()Sebastian Huber2021-04-271-3/+4
| | | | | This avoids having conditional statements to get the API-specific status code.
* score: Canonicalize Doxygen @file commentsSebastian Huber2020-12-021-4/+2
| | | | | | Use common phrases for the file brief descriptions. Update #3706.
* score: Canonicalize Doxygen groupsSebastian Huber2020-12-021-2/+4
| | | | | | | Adjust group identifier and names to be in line with a common pattern. Use common phrases for the group brief descriptions. Update #3706.

* score: _Scheduler_Is_non_preempt_mode_supported()Sebastian Huber2020-02-251-0/+18
| | | | | | | | If the non-preempt mode for threads is supported depends on the scheduler implementation. Add _Scheduler_Is_non_preempt_mode_supported() to indicate this. Update #3876.
* score: Add and use _Thread_Get_unmapped_priority().Sebastian Huber2019-06-281-30/+0
| | | | Add and use _Thread_Get_unmapped_real_priority().
* doxygen: score: adjust doc in schedulerimpl.h to doxygen guidelinesAndreas Dachsberger2019-05-131-70/+227
| | | | Update #3706.
* doxygen: Rename Score* groups in RTEMSScore*Sebastian Huber2019-04-041-1/+1
| | | | Update #3706
* score: Add thread pin/unpin supportSebastian Huber2018-09-101-11/+9
| | | | | | | | | 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: Modify _Scheduler_Unblock()Sebastian Huber2018-09-101-5/+11
| | | | | | | | | In SMP configurations, obtain the scheduler node for the block and unblock operations through the same way via Thread_Control::Scheduler::Scheduler_node. This symmetry is important in a follow up patch which introduces thread pinning. Update #3508.
* Remove make preinstallChris Johns2018-01-251-0/+1203
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.
