| | | | | | | The inter-processor interrupt (IPI) may be used to process per-CPU jobs. See for example the blocked handler in T_interrupt_test(). Update #3199.
* bsps/powerpc: Fix inline assemblySebastian Huber2020-07-052-6/+6
| | | | | GCC 10 no longer passes -many to the assembler. This enables more checks in the assembler.

* bsps: Rework work area initializationSebastian Huber2020-02-041-4/+23
| | | | | | | | | | | | | | | | | | | | The work area initialization was done by the BSP through bsp_work_area_initialize(). This approach predated the system initialization through the system initialization linker set. The workspace and C program heap were unconditionally initialized. The aim is to support RTEMS application configurations which do not need the workspace and C program heap. In these configurations, the workspace and C prgram heap should not get initialized. Change all bsp_work_area_initialize() to implement _Memory_Get() instead. Move the dirty memory, sbrk(), per-CPU data, workspace, and malloc() heap initialization into separate system initialization steps. This makes it also easier to test the individual initialization steps. This change adds a dependency to _Heap_Extend() to all BSPs. This dependency will be removed in a follow up change. Update #3838.
* score: Rename _SMP_Get_processor_count()Sebastian Huber2019-04-111-1/+1
| | | | | | | Rename _SMP_Get_processor_count() in _SMP_Get_processor_maximum() to be in line with the API level rtems_scheduler_get_processor_maximum(). Update #3732.
* score: Rename _SMP_Processor_countSebastian Huber2019-04-111-1/+1
| | | | | | | Rename _SMP_Processor_count in _SMP_Processor_maximum to be in line with the API level rtems_scheduler_get_processor_maximum(). Update #3732.
* rtems: Add rtems_scheduler_get_processor()Sebastian Huber2019-04-091-1/+1
| | | | | | | | | | | 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.
* bsps: Adjust bsp.h Doxygen groupsSebastian Huber2019-03-086-6/+6
| | | | Update #3706.
* bsps/powerpc: Fix small data area sectionSebastian Huber2019-02-112-8/+4
| | | | | | | | | | Fix small data area in case no fixed size is desired. Rename bsp_section_set_sdata_sbss_size into bsp_section_small_data_area_size since this symbol reflects the overall small data area size (including space for libdl). Do not use bsp_section_sbss_size before definition in linker command file. Add new symbols to <bsp/linker-symbols.h>. Update #3687.
* libdl: Add powerpc large memory and small data support.Chris Johns2019-02-092-0/+10
| | | | | | | | | | | | | | | | | - Add support for architecure sections that can be handled by the architecture back end. - Add trampoline/fixup support for PowerPC. This means the PowerPC now supports large memory loading of applications. - Add a bit allocator to manage small block based regions of memory. - Add small data (sdata/sbss) support for the PowerPC. The support makes the linker allocated small data region of memory a global resource available to libdl loaded object files. Updates #3687 Updates #3685

* bsps/powerpc: Fix 64-bit issues in assembler filesSebastian Huber2019-01-251-2/+2
| | | | | | | We have to be careful with instructions which operate explicitly on words or doublewords. Update #3082.
* score: Rename interrupt stack symbolsSebastian Huber2018-11-082-3/+3
| | | | | | | | | | | | | 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.
* bsps/powerpc: Simplify ppc_exc_initialize()Sebastian Huber2018-09-062-4/+2
| | | | | | | Remove parameters from ppc_exc_initialize() since all BSPs passed the same values. Update #3459.
* bsps: BSP_INTERRUPT_STACK_AT_WORK_AREA_BEGINSebastian Huber2018-09-032-5/+3
| | | | | | | Remove the BSP_INTERRUPT_STACK_AT_WORK_AREA_BEGIN hack. The interrupt stacks are now allocated by the linker. Update #3459.
* _SMP_Start_multitasking_on_secondary_processor()Sebastian Huber2018-07-251-2/+2
| | | | | Pass current processor control as first parameter to make dependency more explicit.
* bsps: bsp_start_on_secondary_processor()Sebastian Huber2018-07-252-9/+9
| | | | | | Pass current processor control as first parameter in bsp_start_on_secondary_processor() and qoriq_start_thread() to make dependency more explicit.
* score: _SMP_Inter_processor_interrupt_handler()Sebastian Huber2018-07-251-1/+1
| | | | | Pass current processor control via parameter since it may be already available at the caller side.
* Rework initialization and interrupt stack supportSebastian Huber2018-06-271-12/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* bsps: Support .rtemsstack.* linker input sectionsSebastian Huber2018-06-275-5/+5
| | | | | | Use a dedicated memory region or place it between the BSS and workspace. Update #3459.
* Add _CPU_Counter_frequency()Sebastian Huber2018-06-151-1/+9
| | | | | | | | | | Add rtems_counter_frequency() API function. Use it to initialize the counter value converter via the new system initialization step (RTEMS_SYSINIT_CPU_COUNTER). This decouples the counter implementation and the counter converter. It avoids an unnecessary pull in of the 64-bit integer division from libgcc. Update #3456.
