* rtems: Deprecate region_information_blockSebastian Huber2018-11-092-2/+2
| | | | | | | The region_information_block typedef as no corresponding API. It has no proper namespace prefix. A user can do nothing with it. Close #3591.
* monitor: Remove dead codeSebastian Huber2018-11-082-19/+0

* score: Rename interrupt stack symbolsSebastian Huber2018-11-081-1/+1
| | | | | | | | | | | | | 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.

* stackchk: Fix interrupt stack preparationSebastian Huber2018-09-241-9/+11
| | | | | | We have to prepare the interrupt stack of each processor. Update #3459.
* stackchk: Improve support for interrupt stacksSebastian Huber2018-09-211-29/+84
| | | | | | | | Prepare the interrupt stack which may be used by the boot processor as initialization stack with the stack sanity pattern. Check the interrupt stack of the current processor in the thread begin and switch extension. Update #3459.

| | | | | It is now guranteed that threads do not use a freed stack during termination.
* capture: prevent unaligned access when reading timeDaniel Hellstrom2018-08-241-1/+3
| | | | | | | | | | | | LLVM warns about this: cpukit/libmisc/capture/capture.c:405:30: warning: taking address of packed member 'time' of class or structure 'rtems_capture_record' may result in an unaligned pointer value [-Waddress-of-packed-member] rtems_capture_get_time (&in.time); And on sparc it generates an unaligned trap which makes smpcapture01 and smpcapture02 test to fail on sparc.
* confdefs: Fix uniprocessor configurationSebastian Huber2018-07-301-2/+0
| | | | | | | | | | Introduce a new internal define _CONFIGURE_MAXIMUM_PROCESSORS and ensure that it is _CONFIGURE_MAXIMUM_PROCESSORS > 1 only in SMP configurations. This avoids to allocate data structures for non-existing additional processors in uniprocessor configuration. Update #3459.
* Rework initialization and interrupt stack supportSebastian Huber2018-06-271-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* stackchk: Add SMP supportSebastian Huber2018-06-201-37/+64
| | | | | | | | | | | | Check the interrupt stacks of all processors. Set up the interrupt stack of the current processor for high water testing in the thread begin extension. This must be done after multi-threading started, since the initialization stacks may reuse the interrupt stacks. Disable thread dispatching in SMP configurations to prevent thread migration. Writing to the interrupt stack is only safe if done from the corresponding processor in thread context. Update #3459.

* config: SMP only CONFIGURE_MAXIMUM_PROCESSORSSebastian Huber2018-06-201-1/+3
| | | | | | | Do not set the CONFIGURE_MAXIMUM_PROCESSORS in uni-processor default configuration, since this may lead to an oversize workspace. Update #3459.
* build: Remove EXTRA_DISTSebastian Huber2018-04-041-10/+0
| | | | | A "make dist" is not supported. So, it makes no sense to have pure "make dist" related stuff in the Makefile.am.

* Remove make preinstallChris Johns2018-01-2533-7197/+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.
