2022-03-22cpukit/libmisc/check: Change license to BSD-2Joel Sherrill1-3/+22
Updates #3053.
2022-01-27cpukit: Prevent error with disabled stack checkerKinsey Moore1-0/+5
When the stack checker is not enabled, the stack checker reporting function can still be called. This prevents that call from performing a null memory access in trying to find the high water mark if the stack checker was never initialized. This also introduces a test to ensure this call does not cause a crash. Closes #4588
2021-05-05stackchk: Fixed 32bit pointersStephen Clark1-1/+2
Using 32bit types like uint32_t for pointers creates issues on 64 bit architectures like AArch64. Replaced occurrences of these with uintptr_t, which will work for both 32 and 64 bit architectures.

2020-02-28score: Fix context switch extensions (SMP)Sebastian Huber1-3/+23
In uniprocessor and SMP configurations, the context switch extensions were called during _Thread_Do_dispatch(): void _Thread_Do_dispatch( Per_CPU_Control *cpu_self, ISR_Level level ) { Thread_Control *executing; executing = cpu_self->executing; ... do { Thread_Control *heir; heir = _Thread_Get_heir_and_make_it_executing( cpu_self ); ... _User_extensions_Thread_switch( executing, heir ); ... _Context_Switch( &executing->Registers, &heir->Registers ); ... } while ( cpu_self->dispatch_necessary ); ... } In uniprocessor configurations, this is fine and the context switch extensions are called for all thread switches except the very first thread switch to the initialization thread. However, in SMP configurations, the context switch may be invalidated and updated in the low-level _Context_Switch() routine. See: https://docs.rtems.org/branches/master/c-user/symmetric_multiprocessing_services.html#thread-dispatch-details In case such an update happens, a thread will execute on the processor which was not seen in the previous call of the context switch extensions. This can confuse for example event record consumers which use events generated by a context switch extension. Fixing this is not straight forward. The context switch extensions call must move after the low-level context switch. The problem here is that we may end up in _Thread_Handler(). Adding the context switch extensions call to _Thread_Handler() covers now also the thread switch to the initialization thread. We also have to save the last executing thread (ancestor) of the processor. Registers or the stack cannot be used for this purpose. We have to add it to the per-processor information. Existing extensions may be affected, since now context switch extensions use the stack of the heir thread. The stack checker is affected by this. Calling the thread switch extensions in the low-level context switch is difficult since at this point an intermediate stack is used which is only large enough to enable servicing of interrupts. Update #3885.
2020-02-04stackchk: Add RTEMS_SYSINIT_ISR_STACKSebastian Huber1-2/+2
Use a dedicated system initialization step for the stack checker interrupt stack support. Update #3838.

2019-04-09rtems: Add rtems_scheduler_get_processor_maximum()Sebastian Huber1-1/+1
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.
2018-11-08score: Rename interrupt stack symbolsSebastian Huber1-1/+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.
2018-09-24stackchk: Fix interrupt stack preparationSebastian Huber1-9/+11
We have to prepare the interrupt stack of each processor. Update #3459.
2018-09-21stackchk: Improve support for interrupt stacksSebastian Huber1-29/+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.
2018-09-21stackchk: Remove heap hackSebastian Huber1-7/+1
It is now guranteed that threads do not use a freed stack during termination.
2018-06-27Rework initialization and interrupt stack supportSebastian Huber1-2/+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.
2018-06-20stackchk: Add SMP supportSebastian Huber1-37/+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.

Commit 0fd6f25507fbea5f4892b71b58837cdda17856b4 relaxed the thread begin extension execution environment. This broke the stack check which only partially initialized the stack pattern in its create extension. Move the part of the begin extension to the create extension.

2016-05-25cpukit, testsuite: Add rtems_printf and rtems_printer support.Chris Johns1-19/+17
This change adds rtems_printf and related functions and wraps the RTEMS print plugin support into a user API. All references to the plugin are removed and replaced with the rtems_printer interface. Printk and related functions are made to return a valid number of characters formatted and output. The function attribute to check printf functions has been added to rtems_printf and printk. No changes to remove warrnings are part of this patch set. The testsuite has been moved over to the rtems_printer. The testsuite has a mix of rtems_printer access and direct print control via the tmacros.h header file. The support for begink/endk has been removed as it served no purpose and only confused the code base. The testsuite has not been refactored to use rtems_printf. This is future work.
