* libc: Optimize malloc() initializationSebastian Huber2021-11-302-0/+98
| | | | | | | | | | | | | | | | The BSPs provide memory for the separate C Program Heap initialization via _Memory_Get(). Most BSPs provide exactly one memory area. Only two BSPs provide more than one memory area (arm/altera-cyclone-v and bsps/powerpc/mpc55xxevb). Only if more than one memory area is provided, there is a need to use _Heap_Extend(). Provide two implementations to initialize the separate C Program Heap and let the BSP select one of the implementations based on the number of provided memory areas. This gets rid of a dependency on _Heap_Extend(). It also avoids dead code sections for most BSPs. Change licence to BSD-2-Clause according to file history. Update #3053.

* bsps/gicv2: Allow BSPs to define IRQ attributesKinsey Moore2021-09-213-34/+180
| | | | | | | ARM's GICv2 is configurable and its attributes vary between implementations including omission of specific interrupts. This allows BSPs to accomodate those varying implementations with customized attribute sets.
* bsps/shared: Add PSCI SMP startup supportKinsey Moore2021-09-211-0/+92
| | | | | | | | This adds the SMP function that supports spinup of additional CPU cores using the ARM standard PSCI inteface. This interface is provided by QEMU as well as ARM Trusted Firmware running in monitor mode (EL3) on ARMv7 and AArch64 CPUs. This supports activation va SMC or HVC instructions depending on BSP configuration.
* build: Remove old build systemSebastian Huber2021-09-214-151/+0
| | | | | Close #3250. Close #4081.
* arm/xilinx: Fix zynq-uart interrupt receiveChris Johns2021-09-162-57/+66
| | | | | | | | - Trigger on a single character entering the RX FIFO - Disable the RX timeout - Send up to a FIFO full of data
* bsps/zynq: Moved general i2c files to shared directoriesStephen Clark2021-09-091-0/+482
| | | | | Certain files related to the Zynq BSP's I2C driver are useable by the ZynqMP BSP as well. Moved these files to shared directory in anticipation of I2C support for ZynqMP.
* bsps/cache: Optimize smp_cache_broadcast()Sebastian Huber2021-07-291-1/+2
| | | | | Directly call the handler on the executing processor instead of doing this indirectly via a per-CPU job.
* bsps/irq: bsp_interrupt_facility_initialize()Sebastian Huber2021-07-274-13/+5
| | | | | | 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.
* bsps/irq: Add rtems_interrupt_entry_install()Sebastian Huber2021-07-267-341/+481
| | | | | | | | | | | | | | | | | | | Add rtems_interrupt_entry_remove(). Split up irq-generic.c into several files. In particular, place all functions which use dynamic memory into their own file. Add optional macros to let the BSP customize the vector installation after installing the first entry and the vector removal before removing the last entry: * bsp_interrupt_vector_install() * bsp_interrupt_vector_remove() Use these new customization options in the m68k/genmcf548x BSP so re-use the generic interrupt controller support. Update #3269.
* bsps/irq: Move bsp_interrupt_handler_is_empty()Sebastian Huber2021-07-261-19/+0
| | | | | | This function is only used by one BSP. Update #3269.
* bsps/irq: Add bsp_interrupt_check_and_lock()Sebastian Huber2021-07-262-61/+50
| | | | | | | | Return RTEMS_INCORRECT_STATE instead of RTEMS_INTERNAL_ERROR in case the interrupt support is not initialized. This is similar to rtems_timer_server_fire_after() for example. Update #3269.
* bsps/irq: Use rtems_interrupt_entrySebastian Huber2021-07-262-13/+13
| | | | Update #3269.

* bsps/irq: Add rtems_interrupt_get_attributes()Sebastian Huber2021-07-264-2/+55
| | | | | | | 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 Huber2021-07-266-0/+144
| | | | | | | | | 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 Huber2021-07-264-1/+51
| | | | | | | Add a default implementation which just returns RTEMS_UNSATISFIED for valid parameters. Update #3269.
* rtems: Add RTEMS_FATAL_SOURCE_SPURIOUS_INTERRUPTSebastian Huber2021-07-261-7/+5
| | | | | | | | Add RTEMS_FATAL_SOURCE_SPURIOUS_INTERRUPT as the fatal source for spurious interrupts. Use the interrupt vector number of the spurious interrupt for the fatal code. Update #3269.
* rtems: Add rtems_interrupt_vector_enable()Sebastian Huber2021-07-263-0/+61
| | | | | | Add rtems_interrupt_vector_disable(). Update #3269.

| | | | Update #3269.
* bsps/irq: Canonicalize get/set affinity errorsSebastian Huber2021-07-261-2/+10
| | | | | | | Bring the error conditions and status in line with rtems_task_get_affinity() and rtems_task_set_affinity(). Update #3269.
* bsps/irq: Move get/set affinity to separate fileSebastian Huber2021-07-264-52/+92
| | | | Update #3269.
* bsps: Fix bsp_fatal_extension()Sebastian Huber2021-07-231-0/+3
| | | | The heap protection is conditional.
* bsp: Remove fatal from exit(0). Add extended heap error outputChris Johns2021-07-231-13/+70

* bsps: Fix GICv3 support for AArch32Sebastian Huber2021-06-301-3/+3
| | | | | | | | | | | The GICv3 support is shared between AArch32 and AArch64. For AArch32, the new AARCH64_IS_NONSECURE is never defined. Use ARM_MULTILIB_ARCH_V4 instead. This issue was introduced by 76c6caad52244ab9a14151620a80ff0f71035b6c. There is still a change in bsp_interrupt_vector_enable() for AArch32 compared to the version before 76c6caad52244ab9a14151620a80ff0f71035b6c.
* bsps/zynq-uart: Make post baud change kick globalKinsey Moore2021-06-292-0/+14
| | | | | | | | The existing fix for the ZynqMP UART hardware bug only caught the vast majority of instances where it could occur. To fully fix the data corruption, this fix must be applied after every baud rate change. This makes the logic reset and kick apply in any locations where the baud rate could be changed.
* bsps/aarch64: add non-secure mode and versal supportGedare Bloom2021-06-241-2/+21

* bsps/irq: Use BSP_INTERRUPT_VECTOR_COUNTSebastian Huber2021-06-242-2/+2
| | | | | | Use BSP_INTERRUPT_VECTOR_COUNT instead of BSP_INTERRUPT_VECTOR_MAX. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_NUMBERSebastian Huber2021-06-241-1/+1
| | | | | | Replace it with BSP_INTERRUPT_VECTOR_COUNT. Update #3269.
* bsps/irq: Remove BSP_INTERRUPT_VECTOR_MINSebastian Huber2021-06-241-1/+1
| | | | | | | | | | 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: Remove BSP_INTERRUPT_NO_HEAP_USAGESebastian Huber2021-06-241-31/+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 Banerjee2021-06-231-1663/+0

* bsps/irq: Change license to BSD-2-ClauseSebastian Huber2021-06-178-71/+185
| | | | | | | Change license to BSD-2-Clause according to file history and re-licensing agreement. Update #3053.
* grlib: Simplify apbuart_inbyte_nonblocking()Sebastian Huber2021-06-171-5/+5
|
* grlib: Fix apbuart_outbyte_polled() prototypeSebastian Huber2021-06-171-1/+1
| | | | Callers usually want to output a character.
* grlib: Add apbuart_outbyte_wait()Sebastian Huber2021-06-173-17/+17
|
* grlib: Remove NL -> CR in apbuart_outbyte_polled()Sebastian Huber2021-06-173-9/+2
| | | | This is already done in rtems_putc().
* grlib: Add ambapp_plb()Sebastian Huber2021-06-174-6/+6
| | | | | Replace the global variable ambapp_plb with a function to allow an automatic on demand initialization.
* grlib: Customizable allocation in ambapp_scan()Sebastian Huber2021-06-171-16/+25
| | | | | Make the memory allocations in ambapp_scan() customizable via the new struct ambapp_context parameter which generalizes the memory copy handler.
* rtems: Constify rtems_task_wake_when()Sebastian Huber2021-05-121-1/+1
| | | | | | | | | | | | | | | | Add a parameter to _TOD_Validate() to disable the validation of the ticks member. There are two reasons for this change. Firstly, in rtems_task_wake_when() was a double check for time_buffer == NULL (one in rtems_task_wake_when() and one in _TOD_Validate()). Secondly, the ticks member is ignored by rtems_task_wake_when(). This was done with a write of zero to the ticks member and thus a modification of the user-provided structure. Now the structure is no longer modified. Using a mask parameter is quite efficient. You just have to load an immediate value and there are no additional branches in _TOD_Validate(). Close #4406.
* _TOD_Validate(): Fix incorrect return codeFrank Kühndel2021-05-121-1/+1
| | | | | | | | | | | | | | | This patch fixes bug #4403. Directives * rtems_timer_fire_when() * rtems_timer_server_fire_when() * rtems_task_wake_when() are documented to return RTEMS_INVALID_ADDRESS when their time-of-day argument is NULL. But actually they return RTEMS_INVALID_CLOCK. To fix the issue this patch changes _TOD_Validate() to return a status code instead of just true/false. Close #4403
* bsps/shared/ofw: Fix coverity defectsG S Niteesh Babu2021-05-061-1/+11
| | | | | | | | | | This patch adds asserts to fix coverity defects 1) CID 1474437 (Out-of-bounds access) 2) CID 1474436 (Out-of-bounds access) From manual inspection, out of bounds access cannot occur due to bounds checking but coverity fails to detect the checks. We are adding asserts as a secondary check.
