* untar: Make path also for symbolic linksSebastian Huber2019-11-251-9/+8
| | | | Close #3823.
* untar: Unify untar supportSebastian Huber2019-11-251-94/+87
| | | | Update #3823.
* Move feature macro before "config.h" includeSebastian Huber2019-11-194-9/+12
| | | | | | | This allows to use header includes in "config.h" to reduce the build configuration checks. Update #3818.
* Add and use THREAD_DEFAULT_MAXIMUM_NAME_SIZESebastian Huber2019-07-301-1/+1
|
* misc/rtemsdefaultconfig: Add bdbuf so libbsd can be used with configure.Chris Johns2019-07-021-1/+2
|
* score: Add and use _Thread_Get_unmapped_priority().Sebastian Huber2019-06-282-6/+3
| | | | Add and use _Thread_Get_unmapped_real_priority().
* shell: Avoid rtems_error()Sebastian Huber2019-05-141-9/+0
| | | | | | | Do not use the rtems_error() function since this function pulls in exit() and abort(). The abort() function pulls in raise() which pulls in the whole POSIX signals support. This change saves about 16KiB of text/rodata on ARM Thumb-2 systems.
* rtems: Add rtems_scheduler_get_processor_maximum()Sebastian Huber2019-04-094-6/+6
| | | | | | | | | | | Add rtems_scheduler_get_processor_maximum() as a replacement for rtems_get_processor_count(). The rtems_get_processor_count() is a bit orphaned. Adopt it by the Scheduler Manager. The count is also misleading, since the processor set may have gaps and the actual count of online processors may be less than the value returned by rtems_get_processor_count(). Update #3732.
* rtems: Add rtems_scheduler_get_processor()Sebastian Huber2019-04-091-2/+2
| | | | | | | | | | | Add rtems_scheduler_get_processor() as a replacement for rtems_get_current_processor(). The rtems_get_current_processor() is a bit orphaned. Adopt it by the Scheduler Manager. This is in line with the glibc sched_getcpu() function. Deprecate rtems_get_current_processor(). Update #3731.
* build: Move test support to librtemstest.aSebastian Huber2019-03-265-546/+0
| | | | | | | | One reason to move the test support into a dedicated library are the standard output __wrap_*() functions. They may conflict with application level wrappers. Update #3199.
* main_edit.c: Use strncpy() to eliminate potential buffer overflow.Joel Sherrill2019-03-141-4/+5

* shell: Correct argument order of `mfill`Jonathan Brandmeyer2019-03-081-1/+1
| | | | Close #3720.
* Remove explicit file names from @fileSebastian Huber2019-02-281-1/+1
| | | | | | This makes the @file documentation independent of the actual file name. Update #3707.
* libmisc: Fix rtems_print_bufferChris Johns2019-02-091-1/+1

* rtems: Use object information to get config maxSebastian Huber2018-12-141-9/+9
| | | | | | | Use functions instead of macros. Add missing rtems_configuration_get_maximum_*() functions. Update #3621.
* testsupport: Include missing <rtems/bspIo.h>Sebastian Huber2018-12-031-0/+1
|
* score: Remove support for RTEMS_USE_16_BIT_OBJECTSebastian Huber2018-11-212-8/+0
| | | | | | | | | The RTEMS_USE_16_BIT_OBJECT define is not set by an RTEMS port. Remove support for 16-bit object identifiers. If someone really wants to use RTEMS on a 16-bit target, then it is better to use self-contained objects instead of playing around with object identifier optimizations. Update #3603.
* rtems: Move internal structures to extensiondata.hSebastian Huber2018-11-121-0/+1
| | | | Update #3598.
* rtems: Move internal structures to tasksdata.hSebastian Huber2018-11-121-0/+1

| | | | Update #3599.
* 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
| | | | | Update #3587. Update #3589.
* 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.
* stackchk: Remove heap hackSebastian Huber2018-09-211-7/+1
| | | | | 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.
* stackchk: Refactor Stack_check_Dump_threads_usageSebastian Huber2018-06-201-60/+49
