* malloc: Hide RTEMS_Malloc_Sbrk_amountSebastian Huber2021-04-201-6/+1
| | | | | | Move RTEMS_Malloc_Sbrk_amount to the only implementation file which uses it and make it private to hide implementation-details from an API header.
* libcsupport: Add sbrk greedy support to consume all sbrk memoryChris Johns2021-02-101-0/+13
| | | | | | | | | - Move the heap sbrk code into a separate routnine. - Update heap and workspace greedy allocators to use the common sbrk greedy support. Closes #3982
* Decouple the C Program Heap initializationSebastian Huber2020-10-011-1/+1
| | | | | | | 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.
* bsps: Rework work area initializationSebastian Huber2020-02-041-3/+3
| | | | | | | | | | | | | | | | | | | | The work area initialization was done by the BSP through bsp_work_area_initialize(). This approach predated the system initialization through the system initialization linker set. The workspace and C program heap were unconditionally initialized. The aim is to support RTEMS application configurations which do not need the workspace and C program heap. In these configurations, the workspace and C prgram heap should not get initialized. Change all bsp_work_area_initialize() to implement _Memory_Get() instead. Move the dirty memory, sbrk(), per-CPU data, workspace, and malloc() heap initialization into separate system initialization steps. This makes it also easier to test the individual initialization steps. This change adds a dependency to _Heap_Extend() to all BSPs. This dependency will be removed in a follow up change. Update #3838.
* Remove explicit file names from @fileSebastian Huber2019-02-281-1/+1
| | | | | | This makes the @file documentation independent of the actual file name. Update #3707.
* Add rtems_malloc() and rtems_calloc()Sebastian Huber2018-11-121-0/+33
| | | | Close #3583.
* score: Add and use malloc() family attributesSebastian Huber2018-11-121-1/+2
| | | | Update #3583.
* Remove make preinstallChris Johns2018-01-251-0/+201
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.
