* doxygen: Rename Score* groups in RTEMSScore*Sebastian Huber2019-04-041-1/+1
| | | | Update #3706
* score: Remove fatal is internal indicatorSebastian Huber2016-12-091-1/+1
| | | | | | | | | The fatal is internal indicator is redundant since the fatal source and error code uniquely identify a fatal error. Keep the fatal user extension is internal parameter for backward compatibility and set it to false always. Update #2825.
* score: Delete superfluous Heap_Statistics::instanceSebastian Huber2015-01-221-3/+0
| | | | | This value depends on the _Heap_Initialize() call sequence and carries no useful information.
* score: Fix workspace size estimate for TLSSebastian Huber2014-04-091-1/+2
|
* score: _Heap_Protection_set_delayed_free_fractionSebastian Huber2014-03-241-0/+2
| | | | | Add and use _Heap_Protection_set_delayed_free_fraction(). This makes it possible to avoid a dependency on _Thread_Dispatch_is_enabled().
* Change all references of rtems.com to rtems.org.Chris Johns2014-03-211-1/+1
|
* score: Rename _Internal_error_Occurred()Sebastian Huber2014-02-211-1/+1
| | | | Rename _Internal_error_Occurred() into _Terminate().
* score: Create thread implementation headerSebastian Huber2013-07-261-0/+1
| | | | | | | | Move implementation specific parts of thread.h and thread.inl into new header file threadimpl.h. The thread.h contains now only the application visible API. Remove superfluous header file includes from various files.
* score: Create heap implementation headerSebastian Huber2013-07-231-5/+4
| | | | | | Move implementation specific parts of heap.h and heap.inl into new header file heapimpl.h. The heap.h contains now only the application visible API.
* score: Use _Thread_Get_executing()Sebastian Huber2013-07-221-1/+1

* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-111-2/+0
| | | | | | | | | | | | Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.

The problem is that realloc() can neither grow nor shrink efficiently the current memory region without support from underlying heap/region modules. The patch introduces one new routine for each of heap and region modules, _Heap_Resize_block(), and rtems_region_resize_segment(), respectively, and uses the latter to optimize realloc(). The implementation of _Heap_Resize_block() lead to changing of the heap allocation strategy: now the heap manager, when splits larger free block into used and new free parts, makes the first part of the block used, not the last one as it was before. Due to this new strategy, _Heap_Resize_block() never needs to change the user pointer. Caveat: unlike previous heap implementation, first few bytes of the contents of the memory allocated from the heap are now almost never all zero. This can trigger bugs in client code that have not been visible before this patch. * libcsupport/src/malloc.c (realloc): try to resize segment in place using new rtems_region_resize_segment() routine before falling back to the malloc()/free() method. * score/src/heap.c: (_Heap_Initialize): change initial heap layout to reflect new allocation strategy of using of the lower part of a previously free block when splitting it for the purpose of allocation. (_Heap_Block_allocate): when split, make the lower part used, and leave the upper part free. Return type changed from Heap_Block* to uint32_t. * score/include/rtems/score/heap.h: (Heap_Statistics): added 'resizes' field. (Heap_Resize_status): new enum. (_Heap_Resize_block): new routine. (_Heap_Block_allocate): return type changed from Heap_Block* to uint32_t. * score/src/heapwalk.c: reflect new heap layout in checks. * score/src/heapsizeofuserarea.c: more assertions added. * score/src/heapresizeblock.c: new file. (_Heap_Resize_block): new routine. * score/src/heapfree.c: reverse the checks _Heap_Is_block_in() and _Heap_Is_prev_used() on entry to be in this order. * score/src/heapallocate.c, score/src/heapallocatealigned.c: ignore return value of _Heap_Block_allocate(). * score/Makefile.am (HEAP_C_FILES): added src/heapresizeblock.c. * rtems/include/rtems/rtems/region.h: (rtems_region_resize_segment): new interface routine. (_Region_Process_queue): new internal routine called from rtems_region_resize_segment() and rtems_region_return_segment(). * rtems/src/regionreturnsegment.c: move queue management code into the new internal routine _Region_Process_queue() and call it. * rtems/src/regionresizesegment.c: new file. (rtems_region_resize_segment): new interface routine. * rtems/src/regionprocessqueue.c: new file. (_Region_Process_queue): new internal routine containing queue management code factored out from 'regionreturnsegment.c'. * rtems/Makefile.am (REGION_C_FILES): Added src/regionresizesegment.c, and src/regionprocessqueue.c. * ada/rtems.adb, ada/rtems.ads: Added Region_Resize_Segment.

All gvar.h and conftbl.h files removed from test directories. Configuration parameter maximum_devices added. Core semaphore and mutex handlers added and RTEMS API Semaphore Manager updated to reflect this. Initialization sequence changed to invoke API specific initialization routines. Initialization tasks table now owned by RTEMS Tasks Manager. Added user extension for post-switch. Utilized user extensions to implement API specific functionality like signal dispatching. Added extensions to the System Initialization Thread so that an API can register a function to be invoked while the system is being initialized. These are largely equivalent to the pre-driver and post-driver hooks. Added the Modules file oar-go32_p5, modified oar-go32, and modified the file make/custom/go32.cfg to look at an environment varable which determines what CPU model is being used. All BSPs updated to reflect named devices and clock driver's IOCTL used by the Shared Memory Driver. Also merged clock isr into main file and removed ckisr.c where possible. Updated spsize to reflect new and moved variables. Makefiles for the executive source and include files updated to show break down of files into Core, RTEMS API, and Neither. Header and inline files installed into subdirectory based on whether logically in the Core or a part of the RTEMS API.
