The embedded brains GmbH & Co. KG is the legal successor of embedded brains GmbH.
2023-02-14doxygen: Use @anchor for appl config optionsSebastian Huber1-2/+3
The application configuration options are documented in "cpukit/doxygen/appl-config.h". Since the application configuration option defines are also present in multiple test program sources, the "#OPTION" references cannot be mapped to a unique definition. Add an anchor for each option and reference it to avoid the issues with the multiple definitions. Update #3994.

2018-01-25Remove make preinstallChris Johns1-0/+0
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.
2017-01-26Remove rtems_rate_monotonic_postponed_job_count()Kuan-Hsun Chen1-20/+4
Add a variable named "count" in rtems_rate_monotonic_period_status structure. Revise rtems_rate_monotonic_get_status() for the postponed job count. sptests/sp69: Add in the verification of the postponed job count for rtems_rate_monotonic_get_status(). Update #2795.
2017-01-13classic: adjust names of RM postponed job functionsGedare Bloom1-2/+2
closes #2795
2017-01-13Enhancement of the RMS manager for the overrun handling.Kuan-Hsun Chen1-0/+33
Three additional functions: rtems_rate_monotonic_postponed_job_count, _Rate_monotonic_Renew_deadline, and _Rate_monotonic_Release_postponed_job. Four refined functions: _Rate_monotonic_Activate, _Rate_monotonic_Block_while_expired, rtems_rate_monotonic_period, _Rate_monotonic_Timeout. Rate_monotonic_Control contains one counter for counting the postponed jobs and one for recording the recent deadline. Update #2795.
2016-09-21score: Rework thread priority managementSebastian Huber1-0/+6
Add priority nodes which contribute to the overall thread priority. The actual priority of a thread is now an aggregation of priority nodes. The thread priority aggregation for the home scheduler instance of a thread consists of at least one priority node, which is normally the real priority of the thread. The locking protocols (e.g. priority ceiling and priority inheritance), rate-monotonic period objects and the POSIX sporadic server add, change and remove priority nodes. A thread changes its priority now immediately, e.g. priority changes are not deferred until the thread releases its last resource. Replace the _Thread_Change_priority() function with * _Thread_Priority_perform_actions(), * _Thread_Priority_add(), * _Thread_Priority_remove(), * _Thread_Priority_change(), and * _Thread_Priority_update(). Update #2412. Update #2556.
2016-08-04score: Fix a release/cancel job race conditionSebastian Huber1-0/+5
Split up the potential thread priority change in the scheduler release/cancel job operation. Protect the rate monotonic period state with a dedicated SMP lock. This avoids a race condition during _Rate_monotonic_Timeout() while _Rate_monotonic_Cancel() is called on another processor.
2016-06-22Avoid <rtems/print.h> in <rtems/rtems/ratemon.h>Sebastian Huber1-2/+3
This gets rid of the pull in of <stdarg.h> via <rtems.h> via <rtems/rtems/ratemon.h> via <rtems/print.h>.
2016-05-25cpukit, testsuite: Add rtems_printf and rtems_printer support.Chris Johns1-7/+6
This change adds rtems_printf and related functions and wraps the RTEMS print plugin support into a user API. All references to the plugin are removed and replaced with the rtems_printer interface. Printk and related functions are made to return a valid number of characters formatted and output. The function attribute to check printf functions has been added to rtems_printf and printk. No changes to remove warrnings are part of this patch set. The testsuite has been moved over to the rtems_printer. The testsuite has a mix of rtems_printer access and direct print control via the tmacros.h header file. The support for begink/endk has been removed as it served no purpose and only confused the code base. The testsuite has not been refactored to use rtems_printf. This is future work.
2016-03-22rtems: Rework rate-monotonic schedulerSebastian Huber1-14/+6
Use the default thread lock to protect rate-monotonic state changes. This avoids use of the Giant lock. Split rtems_rate_monotonic_period() body into several static functions. Introduce a new thread wait class THREAD_WAIT_CLASS_PERIOD for period objects to synchronize the blocking operation. Close #2631.
2016-03-21rtems: Delete Rate_monotonic_Period_time_tSebastian Huber1-9/+7
Variables with this type directly used the _Timestamp_*() functions.
2016-03-01score: Delete Thread_CPU_usage_tSebastian Huber1-4/+4
This type is superfluous since all operations with it are done via the _Timestamp_*() functions.

2015-06-15Remove use ticks for statistics configure option.Joel Sherrill1-12/+4
This was obsolete and broken based upon recent time keeping changes. Thie build option was previously enabled by adding USE_TICKS_FOR_STATISTICS=1 to the configure command line. This propagated into the code as preprocessor conditionals using the __RTEMS_USE_TICKS_FOR_STATISTICS__ conditional.

2013-07-23rtems: Create ratemon implementation headerSebastian Huber1-158/+9
Move implementation specific parts of ratemon.h and ratemon.inl into new header file ratemonimpl.h. The ratemon.h contains now only the application visible API.
