* score: Add _CPU_Use_thread_local_storage()Sebastian Huber2022-07-0420-0/+207
| | | | | | | | | | | | At some point during system initialization, the idle threads are created. Afterwards, the boot processor basically executes within the context of an idle thread with thread dispatching disabled. On some architectures, the thread-local storage area of the associated thread must be set in dedicated processor registers. Add the new CPU port function to do this: void _CPU_Use_thread_local_storage( const Context_Control *context ) Close #4672.
* gcov: Add functions to dump the gcov informationSebastian Huber2022-07-043-0/+243
| | | | Update #4670.
* riscv: Include missing header fileSebastian Huber2022-06-241-0/+2
|
* score: Make SMP only code explicitSebastian Huber2022-06-234-3/+31
| | | | | | | Conditional expressions with inline functions are not optimized away if optimization is disabled. Avoid such expressions to prevent dead branches. It helps also during code review to immediately see if a loop is used or not.
* kern_tc.c: Provide a weak hardpps() implementationSebastian Huber2022-06-231-0/+12
| | | | | | | The real implementation of hardpps() is defined in kern_ntptime.c. Use it only if the NTP support is needed by the application. Update #2349.
* score: Use right clock for threadq timeoutsSebastian Huber2022-06-231-2/+2
| | | | | | | | Use CLOCK_REALTIME and CLOCK_MONOTONIC for relative thread queue timeouts instead of CLOCK_REALTIME_COARSE and CLOCK_MONOTONIC_COARSE. This fixes an issue with clock_nanosleep() in combination with clock_gettime(). Close #4669.
* score/cpu: Silence ARM and AARCH64 GCC 12 false trigger array warningChris Johns2022-06-152-1/+7
| | | | | | | | | | | | The false trigger is covered in: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99578 GCC 11 and 12 has been patched for constant pointer casts above 4K. This code casts a constant pointer within the first 4K page. As a result the patch disables the warning. Updates #4662
* kern_tc.c: Update pps_event() for uniprocessor configurationsGabriel Moyano2022-06-101-0/+6
| | | | | | Since pps->capgen equal to zero is not a special value in uniprocessor configurations, there is no need to check for this condition. Update #2349
* arm: Fix PMSA regions for contiguous sectionsSebastian Huber2022-06-081-4/+4
| | | | | | | | | | Sections with identical attributes may be contiguous with a respective begin and end address which is not on a minimum region boundary. The begin address is aligned down to the region base address. The end address is aligned up to the region end address. Account for this in the check for contiguous sections. Update #4202.
* arm: Fix PMSA region mapping with 0x0 end addressSebastian Huber2022-06-081-1/+1
| | | | | | | | A section may span up to the end of the address range. In this case the end address is zero. Use the base address to check if a region should be before another region. Update #4202.
* arm: Fix typoSebastian Huber2022-06-031-2/+2
|
* score: Fix pps_fetch()Sebastian Huber2022-05-271-1/+2
| | | | | | Return early only if there was a timeout, otherwise return the PPS info. Update #2349.
* score: Reformat for code coverageSebastian Huber2022-05-231-2/+18
| | | | Close #2349.

| | | | Update #2349.
* score: Rename tc_getfrequency()Gabriel Moyano2022-05-231-1/+1
| | | | | | Rename tc_getfrequency() to _Timecounter_Get_frequency(). Update #2349.
* kern_tc.c: Replace FreeBSD event mechanism by adding pointers to functionGabriel Moyano2022-05-231-0/+41
| | | | Update #2349.

* x86_64/elf_machdep.h: Replace stub with NetBSD versionRyan Long2022-04-081-4/+76
| | | | | | | The other ports included that architecture's version of this file from NetBSD. This patch follows that pattern. closes #4641
* cpukit/score/cpu/moxie: Change license to BSD-2Joel Sherrill2022-04-018-24/+176

* smp: Add fatal errorSebastian Huber2022-03-241-0/+5
| | | | | | | Add SMP-specifc SMP_FATAL_MULTITASKING_START_ON_NOT_ONLINE_PROCESSOR fatal error. This fatal error helps to diagnose a broken SMP startup sequence. Without this error a context switch using the NULL pointer for the thread control block happens which may be difficult to debug.
* score: Add _IO_Relax()Sebastian Huber2022-03-241-0/+53
| | | | | | | This function may be used to burn a couple of processor cycles with minimum impact on the system bus. It may be used in busy wait loops. Since it is a global function, it is possible to wrap it in device driver test code.
* cpukit/aarch64: Add Per_CPU_Control accessorKinsey Moore2022-03-121-0/+23
| | | | | | Add an architecture-specific implementation for _CPU_Get_current_per_CPU_control() to reduce overhead for getting the current CPU's Per_CPU_Control structure.
* arm: Fix PMSA section to region mappingSebastian Huber2022-03-111-22/+33
| | | | | Fix move of regions. Allow sections to be contained in a region (may happen due to region alignment).
* arm: Add _AArch32_PMSA_Map_sections_to_regions()Sebastian Huber2022-03-112-20/+90
| | | | This simplifies unit testing.
* cpukit/: Scripted embedded brains header file clean upJoel Sherrill2022-03-10102-612/+1
| | | | Updates #4625.
* SMP: Fix start multitasking for some targetsSebastian Huber2022-03-097-0/+59
| | | | | | | | | | | | | The previous SMP multitasking start assumed that the initial heir thread of a processor starts execution in _Thread_Handler(). The _Thread_Handler() sets the interrupt state explicitly by _ISR_Set_level() before it calls the thread entry. Under certain timing conditions, processors may perform an initial context switch to a thread which already executes its thread body (see smptests/smpstart01). In this case, interrupts are disabled after the context switch on targets which do not save/restore the interrupt state during a context switch (aarch64, arm, and riscv). Close #4627.
* score: Disable thread dispatching earlierSebastian Huber2022-03-082-6/+6
| | | | | | | Disable thread dispatching earlier on secondary processors. This ensures that fatal error and per-CPU job handlers are called with thread dispatching disabled. On the boot processor, the thread dispatching is already disabled by _Thread_Dispatch_initialization().
