* rtems: Add rtems_scheduler_get_processor_maximum()Sebastian Huber2019-04-093-4/+4
| | | | | | | | | | | 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.
* 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 architecture Doxygen groupsSebastian Huber2019-03-044-11/+11
| | | | | | | | | | - 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.

* bsps/sparc: Add grlib_malloc(), grlib_calloc()Sebastian Huber2018-12-2138-140/+176
| | | | This avoids a dependency to errno in device driver code.
* Simplify _CPU_Counter_difference()Sebastian Huber2018-12-075-213/+182
| | | | | | | | | | | | | | 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.
* bsp/leon2: Move printk() supportSebastian Huber2018-12-053-88/+31
| | | | | | | | | Avoid assert() in console_inbyte_nonblocking(). Do not poll forever in bsp_in_char(). This allows the caller to decide what to do if no character is available. This entangles some dependencies and fixes a spconfig02 test failure.

| | | | Reduce copy and paste.
* score: Rename interrupt stack symbolsSebastian Huber2018-11-081-2/+2
| | | | | | | | | | | | | 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.
* leon: do not use -mfix-{device} with ClangDaniel Hellstrom2018-10-092-2/+28
| | | | | | | | | Clang do not support -mfix-gr712rc, -mfix-ut700 and -mfix-ut699. Therefore we adjust the CPU_CFLAGS to remove these when compiling with Clang. Instead use GR712RC: -mcpu=gr712rc GR740: -mcpu=gr740 UT699/UT700: Not currently supported by clang, use LEON3 BSP.

* leon, grspw_pkt: support CCSDS/ISO16 data CRCMartin Aberg2018-09-202-2/+17
| | | | | | When the CCSDS/CCITT CRC-16 and 16-bit ISO-checksum logic is available in GRSPW2, the DCRCT field is used to determine how to generate the CRC/checksum code. grspw_hw_sup has been extended with the field ccsds_crc
* leon,grspw_pkt: protect TX descriptor from bad input (hdrlen)Daniel Hellstrom2018-09-201-1/+2
|
* leon, l2cache: workaround for scrubberMartin Aberg2018-09-201-0/+8
| | | | | | | | | | This is a workaround for a L2CACHE scrubber corner case described in GR740 User's Manual, Version 1.10, section 43.2.30. The issue affects some version of the L2CACHE. However, since the performance impact of the workaround is marginal, special device probing logic has been avoided. In addition, this update does not affect users who enable the L2CACHE and scrubber before RTEMS is started.

* bsp/leon3: Fix typo which breaks the CPU counterSebastian Huber2018-09-201-1/+1
| | | | Update #3456.
* network: Use kernel/user space header filesSebastian Huber2018-09-107-8/+7
| | | | | | | | | | Add and use <machine/rtems-bsd-kernel-space.h> and <machine/rtems-bsd-user-space.h> similar to the libbsd to avoid command line defines and defines scattered throught the code base. Simplify cpukit/libnetworking/Makefile.am. Update #3375.
* leon,grspw_pkt: remove incorrect comment on SMP not being testedDaniel Hellstrom2018-08-241-1/+1
| | | | | | To clarify, SMP with GRSWP_PKT driver API has been extended to take advantage of multi-core, is now SMP-safe, and has been tested on GR740.
* leon,apbuart: replace termios c_cflag & CBAUD with c_{i,o}speedDaniel Hellstrom2018-08-241-61/+3
| | | | | | | | | | | ince some time RTEMS started to use the termios c_ispeed and c_ospeed variables in the termios struct to hold the UART baudrate. However the APBUART driver still uses the old c_cflag sometimes causing other UART parameters to get overwritten, for example the partiy setting no mapped to the same bits as the old CBAUD mask. At the same time the RTEMS primitievs for setting/reading c_{i,o}speed is now used.
* leon,greth: enable MAC filtering (promiscous mode, multicast)Daniel Hellstrom2018-08-242-1/+105
| | | | | | | | | | | | | | | | It enabled promiscous mode or sets the multicast filter according to the configuration and parameters to ioctl(SIOCSIFFLAGS), ioctl(SIOCADDMULTI) and ioctl(SIOCDELMULTI). On SIOCADDMULTI/SIOCDELMULTI requests the greth ioctl calls the Ethernet helper functions ether_addmulti()/ether_delmulti() which tells the greth driver when its required to update the MAC multicast filtering. The interface notifies support for multicast by setting IFF_MULTICAST. The GRETH has two registers which contains a bit-mask of allowed MAC addresses. The incomming MAC address is CRC:ed and the CRC is used as an index into the bit-mask to determine to allow or drop the frame.
* leon, greth: 10/100 MAC enable TX BD interruptDaniel Hellstrom2018-08-241-5/+5
| | | | | | | Missed to enable interrupt per TX descriptor. Could lead to TX buffer starvation. Does not affect the GBit code.
* sparc,smp: typo in start.S causing SMP not workingDaniel Hellstrom2018-08-241-1/+1

* bsps/sparc: Move polled APBUART functionsSebastian Huber2018-08-106-124/+62
| | | | This reduces the link-time dependencies and avoids copy-and-paste.
* bsps/sparc: Fix typo in start.SSebastian Huber2018-08-011-1/+1
| | | | | Fix typo in start.S introduced by 4678d1a8b0e74a12809122ef071324c99e78d7ff.
* _SMP_Start_multitasking_on_secondary_processor()Sebastian Huber2018-07-251-1/+1
| | | | | Pass current processor control as first parameter to make dependency more explicit.
* bsps: bsp_start_on_secondary_processor()Sebastian Huber2018-07-252-2/+4
| | | | | | 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 Huber2018-06-272-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Huber2018-06-271-0/+3
| | | | | | Use a dedicated memory region or place it between the BSS and workspace. Update #3459.
* Remove Clock_driver_support_shutdown_hardware()Sebastian Huber2018-06-274-35/+0
| | | | | | | | | | | | | | | | | The aim of this clock driver hook was to stop clock tick interrupts at some late point in the exit() procedure. The use of atexit() pulls in malloc() which pulls in errno. It is incompatible with the intention of the CONFIGURE_DISABLE_NEWLIB_REENTRANCY configuration option. The exit() function must be called from thread context, so accompanied clock tick interrupts should cause no harm. On the contrary, someone may assume a normal operating system operation, e.g. working timeouts. Remove the Clock_driver_support_shutdown_hardware() clock driver hook. Close #3436.
* Add _CPU_Counter_frequency()Sebastian Huber2018-06-152-14/+23
| | | | | | | | | | 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.
* bsps: Move documentation, etc. files to bspsSebastian Huber2018-04-263-0/+191
| | | | | | This patch is a part of the BSP source reorganization. Update #3285.
* bsps: Move make/custom/* files to bspsSebastian Huber2018-04-238-0/+120
| | | | | | | | | Adjust various build files. Remove automatic generation of the c/src/lib/libbsp/*/acinclude.m4 files from bootstrap script. This patch is a part of the BSP source reorganization. Update #3285.
* bsps/leon3: Move AMBA support to bspsSebastian Huber2018-04-201-0/+166
