* bsps: Include <rtems/score/processormaskimpl.h>Sebastian Huber2024-04-091-0/+1
| | | | | This fixes commit b678a199e499b6c3f0b453393434aefaee180423 for SMP configurations.
* bsps: Move declarations to <bsp/irq-generic.h>Sebastian Huber2024-03-271-0/+22
| | | | | | | | | | | Move declarations of bsp_interrupt_get_affinity() and bsp_interrupt_set_affinity() to <bsp/irq-generic.h>. Canonicalize the <bsp/irq.h> includes. Implement bsp_interrupt_get_affinity() and bsp_interrupt_set_affinity() only if needed (usually RTEMS_SMP). Provide stub implementations for i386 to fix build errors.
* bsps/leon3: Use custom CPU counter implementationSebastian Huber2023-10-201-26/+0
| | | | | | | | Merge the timecounter and CPU counter support for the leon3 BSP family. Remove now unused functions from the CPU counter support of the erc32 and leon3 BSPs. Update #4954.
* sparc: Move CPU counter implementationSebastian Huber2023-10-201-0/+177
| | | | | | Enable a BSP-specific CPU counter implementation. Update #4954.
* bsps/sparc: Add files to Doxygen groupsFrank Kühndel2023-07-261-0/+9
| | | | Update #3707.
* bsps/sparc: Remove BSP_POWER_DOWN_AT_FATAL_HALTSebastian Huber2023-07-141-52/+0
| | | | | | Remove the BSP_POWER_DOWN_AT_FATAL_HALT BSP option. Applications should do the customization of the system termination with an initial fatal extension.
* bsp/leon3: Move and simplify bsp_irq_fixup()Sebastian Huber2023-07-141-0/+1
|
* bsps: Remove uses of BSP-specific interrupt APISebastian Huber2023-06-162-34/+11
| | | | Update #3269.
* Update company nameSebastian Huber2023-05-201-1/+1
| | | | | The embedded brains GmbH & Co. KG is the legal successor of embedded brains GmbH.
* doxygen: Add Doxygen files to a groupSebastian Huber2023-02-161-0/+8
| | | | Update #3707.
* bsp/leon3: Move SMP data to start.SSebastian Huber2023-02-101-11/+24
| | | | | | | | | | The LEON3_Boot_Cpu global object is only used by start.S. Move the definition of this object to start.S and use a local symbol .Lbootcpuindex for it. Use a compare-and-swap instruction to assign the boot CPU. This allows a concurrent initialization. Close #4845.
* bsps/sparc: Change license to BSD-2 for files with Gaisler copyrightDaniel Cederman2022-11-1411-45/+256
| | | | | | | | | This patch changes the license to BSD-2 for all source files where the copyright is held by Aeroflex Gaisler, Cobham Gaisler, or Gaisler Research. Some files also includes copyright right statements from OAR and/or embedded Brains in addition to Gaisler. Updates #3053.
* bsps: Sort .noinit* sectionsSebastian Huber2022-07-151-1/+1
| | | | | | | | Sort the .noinit* input sections by name first, then by alignment if two sections have the same name. This allows the placement of begin/end symbols to initialize some areas with a special value. Update #4678.
* score: Canonicalize _CPU_Fatal_halt()Sebastian Huber2021-07-281-14/+9
| | | | | | | | Move _CPU_Fatal_halt() declaration to <rtems/score/cpuimpl.h> and make sure it is a proper declaration of a function which does not return. Fix the type of the error code. If necessary, add the implementation to cpu.c. Implementing _CPU_Fatal_halt() as a function makes it possible to wrap this function for example to fully test _Terminate().
* bsps/irq: bsp_interrupt_facility_initialize()Sebastian Huber2021-07-271-2/+1
| | | | | | Do not return a status code in bsp_interrupt_facility_initialize() since this leads to unreachable code in bsp_interrupt_initialize(). Use RTEMS_DEBUG assertions in bsp_interrupt_facility_initialize() if necessary.
* sparc/irq: Implement new interrupt directivesSebastian Huber2021-07-261-7/+41
| | | | Update #3269.
* bsps/irq: bsp_interrupt_get_affinity()Sebastian Huber2021-07-261-1/+1

* bsps/irq: bsp_interrupt_vector_disable()Sebastian Huber2021-07-261-1/+2
| | | | | | Return a status code for bsp_interrupt_vector_disable(). Update #3269.
* bsps/irq: bsp_interrupt_vector_enable()Sebastian Huber2021-07-261-1/+2

| | | | | | Add a default implementation which just returns RTEMS_UNSATISFIED. Update #3269.
* bsps/irq: Add rtems_interrupt_get_attributes()Sebastian Huber2021-07-261-0/+8
| | | | | | | Add a default implementation which clears the attributes to zero and just returns RTEMS_SUCCESSFUL for valid parameters. Update #3269.
* bsps/irq: Add rtems_interrupt_raise()Sebastian Huber2021-07-261-0/+23
| | | | | | | | | Add rtems_interrupt_raise_on() and rtems_interrupt_clear(). Add a default implementation which just returns RTEMS_UNSATISFIED for valid parameters. Update #3269.
* bsps/irq: Add rtems_interrupt_vector_is_enabled()Sebastian Huber2021-07-261-0/+11
| | | | | | | Add a default implementation which just returns RTEMS_UNSATISFIED for valid parameters. Update #3269.
* bsps/sparc: Improve interrupt affinity supportSebastian Huber2021-07-091-23/+11
| | | | | | | | Fully support the interrupt extension API to set/get the interrupt affinity. Remove LEON3_irq_to_cpu which defined the interrupt to processor mapping in a BSP-specific way. Update #3269.
* sparc: Simplify trap table initializationSebastian Huber2021-06-243-55/+32
| | | | | | | | | | | | | | | Move _ISR_Handler() to a separate file since it is now only used if a handler is installed by _CPU_ISR_install_raw_handler(). Statically initialize the traps for external interrupts to use the new _SPARC_Interrupt_trap() which directly dispatches the interrupt handlers installed by rtems_interrupt_handler_install() via the BSP-provided _SPARC_Interrupt_dispatch(). Since the trap table is now fully statically initialized, there is no longer a dependency on the Cache Manager in the default configuration. Update #4458.
* sparc: More reliable bad trap handlingSebastian Huber2021-06-241-5/+2
| | | | | | | | | | | | | Statically initialize the trap table in start.S to jump to _SPARC_Bad_trap() for all unexpected traps. This enables a proper RTEMS fatal error handling right from the start. Do not rely on the stack and register settings which caused an unexpected trap. Use the ISR stack of the processor to do the fatal error handling. Save the full context which caused the trap. Fatal error handler may use it for error logging. Unify the _CPU_Exception_frame_print() implementations and move it to cpukit. Update #4459.
* bsps/sparc: Add a symbol for each trap table entrySebastian Huber2021-06-241-95/+264
| | | | | | | | This makes it easier to review start.o and set break points to trap table entries. This change was checked by inspecting the trap table in start.o with objdump. Update #4458.
* bsps/sparc: Simplify memory initializationSebastian Huber2021-06-102-34/+39
| | | | | | | | | | | | | Directly initialize the memory in the start sequence defined by start.S instead of using a system initialization handler. This avoids using the global variable rdb_start which used a memory location which was shared with _ERC32_MEC_Timer_Control_Mirror. This change makes it possible to use _Memory_Allocate() even before the system initialization is started. Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* bsps/sparc: Simplify stack initializationSebastian Huber2021-06-101-28/+21
| | | | | | Initialize the stacks for all processors in one place. Do not rely on Per_CPU_Control::interrupt_stack_high and directly use the statically allocated interrupt stack area.
* bsps/sparc: Unify stack initializationSebastian Huber2021-06-101-8/+6
| | | | | Initialize the stacks in start.S in one place and identical to _CPU_Context_Initialize().
* bsps/sparc: Remove support to load data sectionSebastian Huber2021-06-101-32/+4
| | | | | | | | | | | | | | | | | | Remove the support to load the data section and rely on the boot loader. The code is an artifact from the old erc32 days, when we would boot and execute from ROM and the .data had to be copied over to RAM. With leon1/2/3, this is not used anymore as a boot loader is made from the RAM image using a custom tool (mkprom). In SMP configurations, this support was also broken since LEON3_Boot_Cpu (in the data section due to the -1 initialization value) was used quite early in the start sequence. If the data copy is really necessary, then an application can still add this step as a very early system initialization step, since boot_card() and the system initialization loop does not use initialized read-write data (only read-only and BSS data). However, the SMP startup would still not work in this case. A boot loader is a better place to load the sections.

* gr_cpci_gr740.c: Unchecked return value from library (CID #1437630)Ryan Long2021-03-051-1/+3
| | | | | | CID 1437630: Unchecked return value from library in gr_cpci_gr740_init1(). Closes #4290
* gr_leon4_n2x.c: Fix Unchecked return value from library (CID #1399767)Ryan Long2021-03-051-1/+3
| | | | | | CID 1399767: Unchecked return value error from library in gr_cpci_leon4_n2x_init1(). Closes #4285
* bsps: Always install IPI in SMP configsSebastian Huber2020-08-311-10/+4
| | | | | | | 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: Rework work area initializationSebastian Huber2020-02-041-11/+25
| | | | | | | | | | | | | | | | | | | | 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.
* bsps: Remove uses of BSP_GET_WORK_AREA_DEBUGSebastian Huber2020-02-041-28/+0
| | | | | | | | | The code covered by BSP_GET_WORK_AREA_DEBUG was basically dead code since there was no normal way to activate it (e.g. via a BSP configuration option). A follow up patch will bring back this feature through a CONFIGURE_VERBOSE_SYSTEM_INITIALIZATION configuration option. Update #3838.
* bsps: Adjust shared Doxygen groupsSebastian Huber2019-03-083-9/+9
| | | | Update #3706.
* bsps: Adjust architecture Doxygen groupsSebastian Huber2019-03-041-8/+8
| | | | | | | | | | - Use CamelCase as it is not used in our C code. Enables simple search and replace. - Prefix with "RTEMS" to aid deployment and integration. It aids searching and sorting. Update #3706.
