2020-10-01Decouple the C Program Heap initializationSebastian Huber
Before this patch RTEMS_Malloc_Initialize() had a fixed dependency on _Workspace_Area. Introduce _Workspace_Malloc_initializer to have this dependency only if CONFIGURE_UNIFIED_WORK_AREAS is defined by the application configuration.
2020-09-28rtems: Add rtems_message_queue_construct()Sebastian Huber
In contrast to message queues created by rtems_message_queue_create(), the message queues constructed by this directive use a user-provided message buffer storage area. Add RTEMS_MESSAGE_QUEUE_BUFFER() to define a message buffer type for message buffer storage areas. Update #4007.

2020-08-31score: Add stack free handler to TCBSebastian Huber
This avoids a dependency to the stack free function in the thread destruction. Update #3959.
2020-08-31score: Move _Stack_Allocator_free to separate fileSebastian Huber
This decouples the task stack allocation from the deallocation. Update #3959.
2020-08-31score: Add _Stack_Allocator_do_initialize()Sebastian Huber
Do the stack allocator initialization and sanity check only if a user-provided stack allocator was configured. This avoids a dependency of _Thread_Handler_initialization() on the stack allocator. Update #3959.
2020-08-31config: Add zero file descriptor data structuresSebastian Huber
Fix linker errors in the minimum test program on some BSPs introduced by ced28f2cfcee6d32ad7bb72e16b235212eb2eaaf.
2020-08-31rtems: Add _RTEMS_Name_to_id()Sebastian Huber
Simplify object name to identifier directives. Using _RTEMS_Name_to_id() to implement the directives enables a tail call optimization. Change license to BSD-2-Clause according to file history. Update #3053.
2020-08-11libtest: Add T_thread_switch_record()Sebastian Huber
Add support to record thread switch events. This can be used to check that a blocking operation results in the expected sequence of thread switches. Update #3199.
2020-07-23libtest: Add T_interrupt_test()Sebastian Huber
Update #3199.
2020-07-23libtest: Add rtems_test_run()Sebastian Huber

2020-07-23libtest: Add T_busy()Sebastian Huber
Update #3199.
2020-07-05epiphany: Remove support for this targetSebastian Huber
Due to an unmaintained toolchain (internal errors in GCC, no FSF GDB integration) the Epiphany architecture was obsoleted in RTEMS 5.1. Update #3941.
2020-05-06rtems: Add rtems_get_copyright_notice()Sebastian Huber
Update #3973.
2020-04-05Revert "score: Fix _ISR_Stack_area_end"Sebastian Huber
This reverts commit 8e80876bdd54e36fb668eee655eec1dd588daf13 which broke several architectures.
2020-04-03score: Fix _ISR_Stack_area_endSebastian Huber
The _ISR_Stack_area_begin and _ISR_Stack_area_end symbols are in different sections. They must have the same alignment, otherwise the following linker directive could separate them: *(SORT_BY_ALIGNMENT (SORT_BY_NAME (.rtemsstack*))) Update #3799.
2020-03-18record: Add rtems_record_dump()Sebastian Huber
Add rtems_record_dump_base64() and rtems_record_dump_base64_zlib(). Add CONFIGURE_RECORD_FATAL_DUMP_BASE64 and CONFIGURE_RECORD_FATAL_DUMP_BASE64_ZLIB configuration options. Update #3904.
2020-03-16rtems: Add rtems_put_char()Sebastian Huber
Update #3904.
2020-03-16score: Add _IO_Base64()Sebastian Huber
Update #3904.
2020-03-09imfs: Replace devfs with an IMFS specializationSebastian Huber
Add a simplified path evaluation function IMFS_eval_path_devfs() for a device only IMFS configuration. The code size can be further reduced by the application if it disables the support for legacy IO drivers via: #define CONFIGURE_IMFS_DISABLE_MKNOD #define CONFIGURE_IMFS_DISABLE_MKNOD_DEVICE Obsolete CONFIGURE_MAXIMUM_DEVICES. Remove BSP_MAXIMUM_DEVICES. Update #3894. Update #3898.
2020-03-04imfs: Add IMFS_add_node()Sebastian Huber
Update #3894.
2020-03-04rtems: rtems_scheduler_get_processor_maximum()Sebastian Huber
In uniprocessor configurations, use compile-time constants for rtems_scheduler_get_processor_maximum() and rtems_scheduler_get_processor(). This helps compilers and static analyzers to deduce that some loop bodies are only executed once and some conditional statements have a fixed outcome (may improve code generation and reduce false positives). In SMP configurations, directly provide the internal implementation for performance reasons.
2020-03-03rtems: Add rtems_scheduler_map_priority_from_posix()Sebastian Huber
Update #3881.
2020-03-03rtems: Add rtems_scheduler_map_priority_to_posix()Sebastian Huber
Update #3881.
2020-02-26config: Initialize IO drivers on demandSebastian Huber
2020-02-25config: Add <rtems/confdefs/malloc.h>Sebastian Huber
Remove all comments and copyrightable content from the moved content. Use BSD-2-Clause license for new file. Move the default configuration to library files so that application configurations do not include the definitions for the default case. Update #3053. Update #3875.
2020-02-25config: Add _Workspace_Is_unifiedSebastian Huber
Move the unified workspace configuration constant out of the configuration table. Provide a default definition of the unified workspace constant. Update #3875.
2020-02-25config: Add _Thread_Idle_bodySebastian Huber
Move the idle thread body configuration constant out of the configuration table. Provide a default definition of the idle thread body constant. Update #3875.
2020-02-25config: Add _Watchdog_Ticks_per_timesliceSebastian Huber
Move the ticks per timeslice configuration constant out of the configuration table. Add WATCHDOG_TICKS_PER_TIMESLICE_DEFAULT and use it to provide a default definition of the watchdog ticks per timeslice constant. Update #3875.
2020-02-25config: Simplify initialization task configSebastian Huber
With the removal of the CONFIGURE_HAS_OWN_INIT_TASK_TABLE configuration option at most one Classic API user initialization task can be configured. Provide an RTEMS API configuration table for backward compatibility. Update #3873.
2020-02-12score: Simplify _Thread_Initialize()Sebastian Huber
Allocate new thread queue heads during objects information extend. This removes an error case and the last dependency on the workspace in _Thread_Initialize(). Update #3835.
2020-02-12score: Split up objects freeSebastian Huber
Split up the different objects free methods into separate functions. This helps to avoid a dependency on the workspace in case no objects or a static set of objects is configured. Update #3835.
2020-02-12score: Split up objects allocationSebastian Huber
Split up the different objects allocation methods into separate functions. This helps to avoid a dependency on the workspace in case no objects or a static set of objects is configured. Change license to BSD-2-Clause according to file histories. Update #3053. Update #3835.
2020-02-12score: Split stack allocator configurationSebastian Huber
This allows the linker garbage collection to perform its work. Update #3835.
2020-02-12score: Simplify TLS area allocationSebastian Huber
Use the stack area to allocate the TLS area. Update #3835.
2020-02-06config: Add CONFIGURE_DIRTY_MEMORYSebastian Huber
Replace the BSP_DIRTY_MEMORY BSP option with a CONFIGURE_DIRTY_MEMORY configuration option. Update #3843.
2020-02-06sysinit: Add RTEMS_SYSINIT_ZERO_MEMORYSebastian Huber
Use a dedicate system initialization step to zero the memory used for the workspace and C program heap. This avoids dead code in case CONFIGURE_ZERO_WORKSPACE_AUTOMATICALLY is not configured.
2020-02-04config: Add CONFIGURE_VERBOSE_SYSTEM_INITIALIZATIONSebastian Huber
Update #3861.
2020-02-04score: Add _Memory_Fill()Sebastian Huber
Update #3838.
2020-02-04score: Add Memory HandlerSebastian Huber

2019-12-20libtest: Add T_check_task_context() actionSebastian Huber
2019-12-13config: Add _MPCI_ConfigurationSebastian Huber
Replace the user MPCI configuration table with a system provided _MPCI_Configuration. Update #3735.
2019-12-11Add TOD Hooks to allow BSP to take action when TOD is setJoel Sherrill
Two use cases were envisioned for this. 1) a BSP or application which desires to update a real-time clock when the RTEMS TOD is set. 2) a paravirtualized BSP can use this to propagate setting the time in an RTEMS application to the hosting environment. This enables the entire set of applications in the virtualized environments to have a single consistent TOD.
2019-11-19imfs: Add IMFS_make_linfile()Sebastian Huber
Update #3818.
2019-10-08termios: Add Capability to Generate SIGINTR and SIGQUITJoel Sherrill
This patch adds the ability for termios to send SIGINTR on receipt of VINTR and SIGQUIT for VKILL and return -1/EINTR from read() on a termios channel. Importantly, this patch does not alter the default behavior or force POSIX signal code in just because termios is used. The application must explicitly enable the POSIX behavior of generating a signal upon receipt of these characters. This is discussed in the POSIX standard: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap11.html Closes #3800.
2019-10-02Revert "record: Add wrappers for malloc() functions"Sebastian Huber
It was accidentally committed. This reverts commit a314544a278f1533ae001f742d7fe24fcee253e6.
2019-10-01record: Add wrappers for malloc() functionsSebastian Huber
Introduce new library librtemsrecordwrap.a which contains wrappers for operating system functions which produce entry/exit events. The wrappers can be selected during link time via the GNU ld --wrap option. Update #3665.
