2020-08-03dev/spi-memdrv: Fix use of uninit mem_param_ptrSebastian Huber
2020-08-03rtems: Add rtems_interrupt_server_create()Sebastian Huber
Add rtems_interrupt_server_destroy(). Before this patch, the only way to create interrupt servers was rtems_interrupt_server_initialize(). This function creates the default interrupt server and in SMP configurations additional interrupt servers for the additional processors. The interrupt server is heavily used by libbsd. This includes the epoch based reclamation which performs time consuming resource and memory deallocation work. This does not work well with time critical services, for example an UART over SPI or I2C. One approach to address this problem is to allow the application to create custom interrupt servers with the right priority and task properties. The interrupt server API accounted for this, however, it was not implemented before this patch. Close #4034.
2020-07-31bsps/fdt: Make sure data is cache alignedChristian Mauderer
The cache of the fdt blob is flushed after copy. Therefore it should be aligned.
2020-07-23bsps/clock: Fix fast idle clock tick supportSebastian Huber
If we interrupt a thread dispatch critical section (thread dispatch disable level != ISR nest level), then we should not do the fast idle mode since this may delay an ongoing system call forever.
2020-07-14rtems: Remove _Copyright_Notice from API headerSebastian Huber
Close #3981.
2020-04-03bsp/shared/clock: Reset Clock_driver_isrs to correct valueJan Sommer
CLOCK_DRIVER_ISRS_PER_TICK is the configuration define, CLOCK_DRIVER_ISRS_PER_TICK_VALUE is the actual value of ISRS per clock tick, therefore use this one to reset the Clock_driver_isrs after each tick.
2020-03-13bsps: Remove legacy interrupt API from defaultSebastian Huber
This fixes linker issues on the powerpc/virtex4 and powerpc/virtex5 BSPs.
2020-02-25bsps/clock: Use _SMP_Get_processor_maximum()Sebastian Huber
Use a specific test to enable the fast idle mode instead of using the rtems_configuration_is_smp_enabled() workaround. Update #3876.
2020-02-20drvmgr: Fix determination of prefix in grlib uart driverDennis Pfau
drvmgr_get_dev_prefix returns 0 if a prefix was found. Therefore the if condition needs to check for 0, i.e. DRVMGR_OK.
2020-02-16libchip/ns16550: Allow user calculate baud divisorG S Niteesh
This patch will allow the user to pass a function to calculate the baud divisor. This will allow for more flexibility, since for some BSPs like raspberrypi, the calculation of baud divisor is different from what is in the current driver.
2020-02-06config: Add CONFIGURE_DIRTY_MEMORYSebastian Huber
Replace the BSP_DIRTY_MEMORY BSP option with a CONFIGURE_DIRTY_MEMORY configuration option. Update #3843.
2020-02-04Use RTEMS_SYSINIT_ORDER_LAST_BUT_5Sebastian Huber
Use RTEMS_SYSINIT_ORDER_LAST_BUT_5 instead of RTEMS_SYSINIT_ORDER_LAST to allow applications and support functions to place system initialization handlers behind the standard handlers. Update #3838.
2020-02-04bsps: Rework work area initializationSebastian Huber
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.
2020-01-03bsps/irq: fix resource leak in irq-server.cGedare Bloom
Resource leak identified by Coverity (CID 1456675). The value of instances is leaked in case some but not all irq servers are created. It should be stored in bsp_interrupt_server_instances.
2019-12-13rtems: Add and use rtems_object_get_local_node()Sebastian Huber
Update #3841.
2019-12-11mpci: Simplify MPCI configurationSebastian Huber
Use watchdog for shared memory driver instead of a Classic API Timer.
2019-12-11clock: Simplify driver initializationSebastian Huber
Use a system initialization handler instead of a legacy IO driver. Update #3834.
2019-09-20rtems: Add rtems_interrupt_server_entry_move()Sebastian Huber
The use case for this function is the libbsd. In FreeBSD, the interrupt setup and binding to a processor is done in two steps. Message based interrupts like PCIe MSI and MSI-X interrupts can be implemented through interrupt server entries. They are setup at the default interrupt server and may optionally move to an interrupt server bound to a specific processor.
2019-09-06record: Allow tracing of ISR disable/enableSebastian Huber
Directly use the CPU port API in boot_card() to allow tracing of the higher level interrupt disable/enable routines, e.g. _ISR_Local_disable() and _ISR_Local_enable(). Currently, there is no configuration option to enable this. Below is a patch. It may be used to investigate some nasty low level bugs in the system.

2019-05-20score: Simplify _SMP_Multicast_action()Sebastian Huber
Move resposibility to disable thread dispatching to the caller of _SMP_Multicast_action(). Using an interrupt disable for this purpose is questionable.
2019-05-20score: Add _SMP_Broadcast_action()Sebastian Huber
2019-05-16bsps: Always build generic interrupt supportSebastian Huber
This makes it possible to write tests for the generic interrupt controller support. Update #3269.

Processor_mask is the internal data type to deal with processor sets.
2019-04-11score: Rename _SMP_Get_processor_count()Sebastian Huber
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.
2019-04-09rtems: Add rtems_scheduler_get_processor_maximum()Sebastian Huber
Add rtems_scheduler_get_processor_maximum() as a replacement for rtems_get_processor_count(). The rtems_get_processor_count() is a bit orphaned. Adopt it by the Scheduler Manager. The count is also misleading, since the processor set may have gaps and the actual count of online processors may be less than the value returned by rtems_get_processor_count(). Update #3732.

- 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.

2018-12-07Simplify _CPU_Counter_difference()Sebastian Huber
In order to simplify the use of CPU counter values it is beneficial to have monotonic increasing values within the range of the CPU counter ticks data type, e.g. 32-bit unsigned integer. This eases the use of CPU counter timestamps in external tools which do not know the details of the CPU counter hardware. The CPU counter is the fastest way to get a time on an RTEMS system. Such a CPU counter may be also used as the timecounter. Use it on SPARC for this purpose to simplify the clock drivers. Update #3456.

2018-11-26Remove rtems_cache_*_processor_set() functionsSebastian Huber
The following rtems_cache_*_processor_set() cache manager API functions are exotic, complex, very hard to use correctly, not used in the RTEMS code base, and apparently unused by applications. Close #3622.

2018-10-17serial/ns16550: Fix precision clock synthesizerSebastian Huber
The precision clock synthesizer support broke the driver on the QorIQ P1020. On this device the Alternate Function Register is accessed with DLAB == 1 instead of the FIFO Control Register (FCR). Restructure the code to account for this.
