* rtems: Move from <rtems.h> to <rtems/config.h>Sebastian Huber2020-09-181-0/+17
| | | | | | Move configuration related declarations and definitions to <rtems/config.h>. The goal is to make <rtems.h> an include only header file.
* config: Remove CONFIGURE_DISABLE_SMP_CONFIGURATIONSebastian Huber2020-02-251-13/+0
| | | | | | | | | | The CONFIGURE_DISABLE_SMP_CONFIGURATION configuration option and rtems_configuration_is_smp_enabled() were added during the SMP support development cycle as a workaround to fix some testsuite failures in SMP configurations. All use cases were replaced with tests for specific conditions. The configuration option and test macro were undocumented. Close #3876.
* config: Add _SMP_Is_enabledSebastian Huber2020-02-251-29/+2
| | | | | | | | | | Move the is SMP enabled configuration constant out of the configuration table. Since this was the last configuration constant in rtems_configuration_table, remove this type. Update #3875.
* config: Add _SMP_Processor_configure_maximumSebastian Huber2020-02-251-11/+3
| | | | | | | Move the processor maximum configuration constant out of the configuration table. Update #3875.
* config: Add _Workspace_Is_unifiedSebastian Huber2020-02-251-9/+1
| | | | | | | | | Move the unified workspace configuration constant out of the configuration table. Provide a default definition of the unified workspace constant. Update #3875.
* config: Add _Workspace_SizeSebastian Huber2020-02-251-6/+2
| | | | | | | Move the workspace size configuration constant out of the configuration table. Update #3875.
* config: Add _Thread_Idle_bodySebastian Huber2020-02-251-7/+1
| | | | | | | | | Move the idle thread body configuration constant out of the configuration table. Provide a default definition of the idle thread body constant. Update #3875.
* config: Add _Thread_Idle_stack_sizeSebastian Huber2020-02-251-8/+2
| | | | | | | | | | Move the idle thread stack size configuration constant out of the configuration table. Add THREAD_IDLE_STACK_SIZE_DEFAULT and use it to provide a default definition of the idle thread stack size constant. Update #3875.
* config: Add _Watchdog_Ticks_per_timesliceSebastian Huber2020-02-251-6/+1
| | | | | | | | | | 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.
* config: Add _Watchdog_Microseconds_per_tickSebastian Huber2020-02-251-8/+2
| | | | | | | | | | Move the microseconds per tick configuration constant out of the configuration table. Add WATCHDOG_MICROSECONDS_PER_TICK_DEFAULT and use it to provide a default definition of the watchdog ticks constants. Update #3875.
* config: Remove CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLESebastian Huber2020-02-251-1/+0
| | | | | | | | | | | | | | | | | | | The CONFIGURE_HAS_OWN_INIT_TASK_TABLE and CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE are the last *_HAS_OWN_* configuration options. These two options are probably unused, see also: * https://lists.rtems.org/pipermail/users/2019-April/033129.html * https://lists.rtems.org/pipermail/users/2019-April/033130.html Removing them simplifies the configuration. If there is a real user need which shows up after the removal, we can resurrect them on demand. Using CONFIGURE_POSIX_HAS_OWN_INIT_THREAD_TABLE would have required the use of the undocumented CONFIGURE_POSIX_INIT_THREAD_TABLE_NAME and CONFIGURE_POSIX_INIT_THREAD_TABLE_SIZE configuration options. Update #3874.
* config: Simplify initialization task configSebastian Huber2020-02-251-3/+0
| | | | | | | | | | 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.
* config: Remove unused configuration constantSebastian Huber2020-02-171-10/+0
|
* Remove rtems_configuration_get_posix_api_configuration()Sebastian Huber2020-02-171-3/+0
| | | | | | | The corresponding data structure not longer exists. This function was not tested and documented. Close #3871.
* score: Split stack allocator configurationSebastian Huber2020-02-121-43/+20
| | | | | | This allows the linker garbage collection to perform its work. Update #3835.
* score: Simplify TLS area allocationSebastian Huber2020-02-121-7/+1
| | | | | | Use the stack area to allocate the TLS area. Update #3835.
* sysinit: Add RTEMS_SYSINIT_ZERO_MEMORYSebastian Huber2020-02-061-9/+2
| | | | | | | | 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.
* config: Add _MPCI_ConfigurationSebastian Huber2019-12-131-60/+3
| | | | | | | Replace the user MPCI configuration table with a system provided _MPCI_Configuration. Update #3735.
* userext: Fix configurationSebastian Huber2019-12-091-1/+0
|
* userext: Simplify configurationSebastian Huber2019-12-091-3/+3
| | | | | Avoid the use of the workspace and use statically allocated switch controls for the initial extensions.
* score: Static Objects_Information initializationSebastian Huber2018-12-141-12/+0
| | | | | | | | | | | Statically allocate the objects information together with the initial set of objects either via <rtems/confdefs.h>. Provide default object informations with zero objects via librtemscpu.a. This greatly simplifies the workspace size estimate. RTEMS applications which do not use the unlimited objects option are easier to debug since all objects reside now in statically allocated objects of the right types. Close #3621.
* rtems: Use object information to get config maxSebastian Huber2018-12-141-2/+1
| | | | | | | Use functions instead of macros. Add missing rtems_configuration_get_maximum_*() functions. Update #3621.
* score: Introduce <rtems/score/watchdogticks.h>Sebastian Huber2018-11-121-1/+1
| | | | | | | Separate the definitions related to watchdog ticks from the watchdog structures. Update #3598.
* config: Move includes out of extern "C" scopeSebastian Huber2018-11-081-4/+4
|
* score: Rename interrupt stack symbolsSebastian Huber2018-11-081-27/+2
| | | | | | | | | | | | | Rename * _Configuration_Interrupt_stack_area_begin in _ISR_Stack_area_begin, * _Configuration_Interrupt_stack_area_end in _ISR_Stack_area_end, and * _Configuration_Interrupt_stack_size in _ISR_Stack_size. Move definitions to <rtems/score/isr.h>. The new names are considerable shorter and in the right namespace. Update #3459.
* config: Move definitions after includesSebastian Huber2018-11-071-8/+8

* posix: Fix build with POSIX API disabledSebastian Huber2018-10-251-13/+1
| | | | Update #2514.
* Rework initialization and interrupt stack supportSebastian Huber2018-06-271-8/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Statically initialize the interrupt stack area (_Configuration_Interrupt_stack_area_begin, _Configuration_Interrupt_stack_area_end, and _Configuration_Interrupt_stack_size) via <rtems/confdefs.h>. Place the interrupt stack area in a special section ".rtemsstack.interrupt". Let BSPs define the optimal placement of this section in their linker command files (e.g. in a fast on-chip memory). This change makes makes the CPU_HAS_SOFTWARE_INTERRUPT_STACK and CPU_HAS_HARDWARE_INTERRUPT_STACK CPU port defines superfluous, since the low level initialization code has all information available via global symbols. This change makes the CPU_ALLOCATE_INTERRUPT_STACK CPU port define superfluous, since the interrupt stacks are allocated by confdefs.h for all architectures. There is no need for BSP-specific linker command file magic (except the section placement), see previous ARM linker command file as a bad example. Remove _CPU_Install_interrupt_stack(). Initialize the hardware interrupt stack in _CPU_Initialize() if necessary (e.g. m68k_install_interrupt_stack()). The optional _CPU_Interrupt_stack_setup() is still useful to customize the registration of the interrupt stack area in the per-CPU information. The initialization stack can reuse the interrupt stack, since * interrupts are disabled during the sequential system initialization, and * the boot_card() function does not return. This stack resuse saves memory. Changes per architecture: arm: * Mostly replace the linker symbol based configuration of stacks with the standard <rtems/confdefs.h> configuration via CONFIGURE_INTERRUPT_STACK_SIZE. The size of the FIQ, ABT and UND mode stack is still defined via linker symbols. These modes are rarely used in applications and the default values provided by the BSP should be sufficient in most cases. * Remove the bsp_processor_count linker symbol hack used for the SMP support. This is possible since the interrupt stack area is now allocated by the linker and not allocated from the heap. This makes some configure.ac stuff obsolete. Remove the now superfluous BSP variants altcycv_devkit_smp and realview_pbx_a9_qemu_smp. bfin: * Remove unused magic linker command file allocation of initialization stack. Maybe a previous linker command file copy and paste problem? In the start.S the initialization stack is set to a hard coded value. lm32, m32c, mips, nios2, riscv, sh, v850: * Remove magic linker command file allocation of initialization stack. Reuse interrupt stack for initialization stack. m68k: * Remove magic linker command file allocation of initialization stack. Reuse interrupt stack for initialization stack. powerpc: * Remove magic linker command file allocation of initialization stack. Reuse interrupt stack for initialization stack. * Used dedicated memory region (REGION_RTEMSSTACK) for the interrupt stack on BSPs using the shared linkcmds.base (replacement for REGION_RWEXTRA). sparc: * Remove the hard coded initialization stack. Use the interrupt stack for the initialization stack on the boot processor. This saves 16KiB of RAM. Update #3459.
* Remove make preinstallChris Johns2018-01-251-0/+397
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.
