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.

2016-03-29score: Remove Thread_queue_Queue::operations fieldSebastian Huber1-0/+1
Remove the Thread_queue_Queue::operations field to reduce the size of this structure. Add a thread queue operations parameter to the _Thread_queue_First(), _Thread_queue_First_locked(), _Thread_queue_Enqueue(), _Thread_queue_Dequeue() and _Thread_queue_Flush() functions. This is a preparation patch to reduce the size of several synchronization objects.

PR 746/rtems Optimize realloc(). 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.

* libcsupport/src/mallocfreespace.c, rtems/Makefile.am, rtems/include/rtems/rtems/region.h, score/Makefile.am, score/include/rtems/score/heap.h, score/src/heapgetinfo.c: Add capability to return information about just the free blocks in a region or heap. Also changed the semantics of free space available to be the largest block of memory that can be allocated. * rtems/src/regiongetfreeinfo.c, score/src/heapgetfreeinfo.c: New files. : score/include/rtems/score/object.h, score/src/objectinitializeinformation.c: Remove warning.
