* Update Strong APA SchedulerRichi Dubey2021-06-243-229/+924
| | | | | | | | | | This change allows for the migration of higher priority tasks on the arrival of a lower priority task limited by affinity constraints. Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* sparc: Simplify trap table initializationSebastian Huber2021-06-2415-170/+704
| | | | | | | | | | | | | | | 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.
* bsps: bsp_interrupt_handler_dispatch_unchecked()Sebastian Huber2021-06-241-19/+40
| | | | | | Add bsp_interrupt_handler_dispatch_unchecked() as an alternative to bsp_interrupt_handler_dispatch(). It may be used if the caller can ensure that the vector number is valid.
* sparc: Move FP frame offset defines to cpuimpl.hSebastian Huber2021-06-242-57/+57
| | | | | | This makes them usable in multiple files. Update #4458.
* bsps/sparc: Use rtems_interrupt_handler_install()Sebastian Huber2021-06-2410-31/+98
| | | | | | | Avoid using set_vector() which depends on _ISR_Vector_table(). Prepare for a statically initialized trap table. Update #4458.
* sparc: More reliable bad trap handlingSebastian Huber2021-06-2423-585/+519
| | | | | | | | | | | | | 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.
* sparc: Move ISR handler install routinesSebastian Huber2021-06-244-174/+203
| | | | | | | | Move _CPU_ISR_install_raw_handler() and _CPU_ISR_install_vector() to separate files. The goal is to make their use optional. Update #4458. 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.
* score: Move _ISR_Vector_table[] to separate fileSebastian Huber2021-06-244-8/+50
| | | | | | | | | | 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.
* score: Remove bogus _ISR_Nest_level settingSebastian Huber2021-06-241-4/+0
| | | | | | | This variable is actually contained in _Per_CPU_Information[] which is already zero initialized. Remove superfluous includes.
* score: Remove _CPU_Initialize_vectors()Sebastian Huber2021-06-2413-76/+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.
* bsp/atsam: Fix BSP_INTERRUPT_VECTOR_COUNTSebastian Huber2021-06-241-1/+1
| | | | | | Fix an off by one error. Update #3269.
* bsps/irq: Default BSP_INTERRUPT_VECTOR_COUNT == 0Sebastian Huber2021-06-241-2/+5
| | | | | | | Change the default value of BSP_INTERRUPT_VECTOR_COUNT so that no interrupt vectors are supported and all related directives return RTEMS_INVALID_ID. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_MAXSebastian Huber2021-06-2455-65/+0
| | | | | | This define is no longer used. Update #3269.
* bsps/irq: Use BSP_INTERRUPT_VECTOR_COUNTSebastian Huber2021-06-2416-22/+22
| | | | | | Use BSP_INTERRUPT_VECTOR_COUNT instead of BSP_INTERRUPT_VECTOR_MAX. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_NUMBERSebastian Huber2021-06-242-4/+2
| | | | | | Replace it with BSP_INTERRUPT_VECTOR_COUNT. Update #3269.
* bsps/irq: Add BSP_INTERRUPT_VECTOR_COUNTSebastian Huber2021-06-2455-0/+67
| | | | | | | | | | | | | Assert BSP_INTERRUPT_VECTOR_MAX + 1 == BSP_INTERRUPT_VECTOR_COUNT. After building all BSPs with this patch, BSP_INTERRUPT_VECTOR_MAX can be removed and replaced by BSP_INTERRUPT_VECTOR_COUNT. The BSP_INTERRUPT_VECTOR_COUNT allows a default implementation which supports no interrupt vector at all. Using COUNT instead of MAX may avoid some interpretation issues, for example is the maximum value a valid vector number or not. Update #3269.
* smpcapture02: Fix use of BSP_INTERRUPT_VECTOR_MAXSebastian Huber2021-06-241-1/+1
| | | | | | This define represents the last valid interrupt vector number. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_MINSebastian Huber2021-06-2461-107/+16
| | | | | | | | | | Remove BSP_INTERRUPT_VECTOR_MIN and unconditionally let interrupt vector numbers start with zero. The BSP_INTERRUPT_VECTOR_MIN == 0 invariant was tested by the previous commit and building all BSPs. Update #3269.
* bsps/irq: Assert BSP_INTERRUPT_VECTOR_MIN == 0Sebastian Huber2021-06-241-0/+4
| | | | | | | After building all BSPs with this patch, this BSP-specific define can be removed to simplify the implementation. Update #3269.
* bsp/generic_or1k: Remove incomplete IRQ supportSebastian Huber2021-06-244-53/+3
| | | | Update #3269.
* bsp/genmcf548x: Change BSP_INTERRUPT_VECTOR_MINSebastian Huber2021-06-241-1/+9
| | | | | | | | | This BSP uses a customized implementation of the interrupt extension API. It was the only BSP which defined BSP_INTERRUPT_VECTOR_MIN to a value other than zero. Define it to zero and use a custom bsp_interrupt_is_valid_vector() function instead. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_NO_HEAP_USAGESebastian Huber2021-06-243-40/+3
| | | | | | | Remove the support for BSP_INTERRUPT_NO_HEAP_USAGE. This was only used by one BSP and provides no real benefit. Update #3269.
* grlib: Register system console as /dev/consoleSebastian Huber2021-06-241-1/+5
| | | | Close #4461.
* bsps/powerpc, bsps/shared: Move remaining legacy networking header filesVijay Kumar Banerjee2021-06-2310-2364/+0
|
* bsp/leon3: Fix compile errorSebastian Huber2021-06-231-1/+1
| | | | Fix compile error with RTEMS_DRVMGR_STARTUP = True.
* i2c: Add non blocking read / writeChristian Mauderer2021-06-223-7/+203
| | | | | | | This adds the possibility to open an I2C bus with O_NONBLOCK (or set it later via fcntl) to get non-blocking transmissions. This means that if the bus is busy, a read, write or transfer ioctl will return with a EAGAIN errno.
* cpukit: Add timespecisnonnegative to Makefile.amRyan Long2021-06-211-0/+1
|
* cpu/armv7m: Fix initialization of MPU regionsChristian Mauderer2021-06-211-1/+1
| | | | | | | | | | | The write to RBAR didn't have the valid flag set. Therefore the write to RASR had an influence on the previously set region. That means for example that if Region 0 had been enabled but 1 should be disabled due to a size of 0, the previous code would have disabled region 0 instead. This patch fixes that behaviour. Close #4450
* cpu/armv7m: Avoid regions with negative sizeChristian Mauderer2021-06-211-1/+1
| | | | | | | Don't initialze regions that have a negative size (for example due to a wrong calculation). Update #4450
* bsps/i386: Update calibration of TSC to be more accurateJan Sommer2021-06-211-33/+38
| | | | Closes #4455
* bsps/irq: Change license to BSD-2-ClauseSebastian Huber2021-06-1711-97/+242
| | | | | | | Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* rtems: Fix rtems_task_set_affinity() docsSebastian Huber2021-06-171-1/+1

* grlib: Simplify apbuart_inbyte_nonblocking()Sebastian Huber2021-06-171-5/+5
|
* grlib: Fix apbuart_outbyte_polled() prototypeSebastian Huber2021-06-172-2/+2
| | | | Callers usually want to output a character.
* grlib: Add apbuart_outbyte_wait()Sebastian Huber2021-06-176-24/+24
|
* grlib: Remove NL -> CR in apbuart_outbyte_polled()Sebastian Huber2021-06-176-12/+4
| | | | This is already done in rtems_putc().
* bsps/leon3: Auto initialization for printk()Sebastian Huber2021-06-171-28/+14
| | | | | | Get rid of the hack to output into the idle stack during the early system initialization. This fixes also a couple of test program failures which fail due to missing output.
* grlib: Add ambapp_plb()Sebastian Huber2021-06-1719-63/+96
| | | | | Replace the global variable ambapp_plb with a function to allow an automatic on demand initialization.
* grlib: Customizable allocation in ambapp_scan()Sebastian Huber2021-06-172-26/+42
| | | | | Make the memory allocations in ambapp_scan() customizable via the new struct ambapp_context parameter which generalizes the memory copy handler.
* arm: Fix parameter use in AARCH32_PMSA_MEM_ATTR()Sebastian Huber2021-06-161-1/+1
| | | | Update #4202.
* score: Comment _Thread_queue_Surrender_sticky()Sebastian Huber2021-06-151-1/+7
| | | | | The change also helps to avoid reports from static analysers since most callers of _Thread_queue_Make_ready_again() check the unblock status.
* Use a common phrase for pointer parametersSebastian Huber2021-06-1514-181/+180
| | | | | | | Mention the type of the pointer in the parameter description. Use the more general term "object" instead of "variable". Update #3993.
* score: Add PER_CPU_DATA_NEED_INITIALIZATION()Sebastian Huber2021-06-108-55/+118
| | | | | | | | | Make the initialization of the per-CPU data optional. Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* splinkersets01: Test linker sets in librarySebastian Huber2021-06-107-7/+66
| | | | | Make sure that the linker sets work if placed in a library (this is how they are used in RTEMS).
* 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.
