2023-09-15rtems: rtems_configuration_get_interrupt_stack_size()Sebastian Huber1-0/+2
Fix rtems_configuration_get_interrupt_stack_size() for some code models. The _ISR_Stack_size symbol has an arbitrary absolute address and may not be representable in the code model used by the compiler. Update #4953.
2022-02-28score/src/[a-m]*.c: Change license to BSD-2Joel Sherrill1-3/+22
Updates #3053.
2021-06-24score: Move _ISR_Vector_table[] to separate fileSebastian Huber1-8/+0
The _ISR_Handler_initialization() does not touch the _ISR_Vector_table[]. Move the definition of _ISR_Vector_table[] to a separate file. Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
2021-06-24score: Remove bogus _ISR_Nest_level settingSebastian Huber1-4/+0
This variable is actually contained in _Per_CPU_Information[] which is already zero initialized. Remove superfluous includes.
2021-06-24score: Remove _CPU_Initialize_vectors()Sebastian Huber1-4/+0
This CPU port macro was not used. Since the _ISR_Vector_table[] is statically allocated, CPU ports could initialize this table in _CPU_Initialize() if necessary. Remove _CPU_Initialize_vectors() to simplify the CPU port interface.

2019-04-04doxygen: Rename Score* groups in RTEMSScore*Sebastian Huber1-1/+1
Update #3706
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.
2018-09-21Remove INTERNAL_ERROR_INTERRUPT_STACK_TOO_SMALLSebastian Huber1-4/+0
The configured interrupt stack size (CONFIGURE_INTERRUPT_STACK_SIZE) is checked against the minimum task stack size. The minium tasks task stack size is also a configuration option (CONFIGURE_MINIMUM_TASK_STACK_SIZE). So, this check does not really help in case of configuration errors. In addition, the interrupt stack is also re-used as the initialization stack in most BSPs. It is probably better to use a stack checker to detect problems. Update #3459.
2018-06-27Rework initialization and interrupt stack supportSebastian Huber1-34/+30
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.

2016-12-09score: Remove fatal is internal indicatorSebastian Huber1-1/+0
The fatal is internal indicator is redundant since the fatal source and error code uniquely identify a fatal error. Keep the fatal user extension is internal parameter for backward compatibility and set it to false always. Update #2825.

Use "cpu" for an arbitrary Per_CPU_Control variable. Use "cpu_self" for the Per_CPU_Control of the current processor. Use "cpu_index" for an arbitrary processor index. Use "cpu_index_self" for the processor index of the current processor. Use "cpu_count" for the processor count obtained via _SMP_Get_processor_count(). Use "cpu_max" for the processor maximum obtained by rtems_configuration_get_maximum_processors().

1995-09-11The word "RTEMS" almost completely removed from the core.Joel Sherrill1-0/+60
Configuration Table Template file added and all tests modified to use this. All gvar.h and conftbl.h files removed from test directories. Configuration parameter maximum_devices added. Core semaphore and mutex handlers added and RTEMS API Semaphore Manager updated to reflect this. Initialization sequence changed to invoke API specific initialization routines. Initialization tasks table now owned by RTEMS Tasks Manager. Added user extension for post-switch. Utilized user extensions to implement API specific functionality like signal dispatching. Added extensions to the System Initialization Thread so that an API can register a function to be invoked while the system is being initialized. These are largely equivalent to the pre-driver and post-driver hooks. Added the Modules file oar-go32_p5, modified oar-go32, and modified the file make/custom/go32.cfg to look at an environment varable which determines what CPU model is being used. All BSPs updated to reflect named devices and clock driver's IOCTL used by the Shared Memory Driver. Also merged clock isr into main file and removed ckisr.c where possible. Updated spsize to reflect new and moved variables. Makefiles for the executive source and include files updated to show break down of files into Core, RTEMS API, and Neither. Header and inline files installed into subdirectory based on whether logically in the Core or a part of the RTEMS API.
