2023-10-20sparc: Move CPU counter implementationSebastian Huber1-0/+7
Enable a BSP-specific CPU counter implementation. Update #4954.
2023-09-15score: Add _CPU_Get_TLS_thread_pointer()Sebastian Huber1-0/+7
Add _CPU_Get_TLS_thread_pointer() to get the thread pointer which is used to get the address of thread-local storage objects associated with a thread. Update #4920.
2023-05-20Update company nameSebastian Huber1-1/+1
The embedded brains GmbH & Co. KG is the legal successor of embedded brains GmbH.
2023-03-15sparc: Add header files to Doxygen groupSebastian Huber1-1/+4
2022-10-14score: Add CPU_THREAD_LOCAL_STORAGE_VARIANTSebastian Huber1-0/+2
Update #3835.
2022-09-19Do not use RTEMS_INLINE_ROUTINESebastian Huber1-3/+3
Directly use "static inline" which is available in C99 and later. This brings the RTEMS implementation closer to standard C. Close #3935.
2022-07-04score: Add _CPU_Use_thread_local_storage()Sebastian Huber1-0/+12
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.
2022-02-28score/cpu/sparc: Change license to BSD-2Joel Sherrill1-3/+22
Updates #3053.
2021-07-28score: Canonicalize _CPU_Fatal_halt()Sebastian Huber1-0/+2
Move _CPU_Fatal_halt() declaration to <rtems/score/cpuimpl.h> and make sure it is a proper declaration of a function which does not return. Fix the type of the error code. If necessary, add the implementation to cpu.c. Implementing _CPU_Fatal_halt() as a function makes it possible to wrap this function for example to fully test _Terminate().
2021-06-24sparc: Move FP frame offset defines to cpuimpl.hSebastian Huber1-0/+21
This makes them usable in multiple files. Update #4458.
2021-06-24sparc: More reliable bad trap handlingSebastian Huber1-0/+22
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.
2019-04-02doxygen: score: Add SPARC CPU architecture groupAndreas Dachsberger1-0/+12
Update #3706.
2018-09-20sparc: clang AS does no accept UNIMP without argumentDaniel Hellstrom1-1/+1
2018-07-23score: Add _CPU_Instruction_illegal()Sebastian Huber1-0/+5
On some architectures/simulators it is difficult to provoke an exception with misaligned or illegal data loads. Use an illegal instruction instead. Update #3433.
2018-07-20score: Add _CPU_Instruction_no_operation()Sebastian Huber1-0/+5
This helps to reduce the use of architecture-specific defines throughout the code base.
2018-07-20score: Move context validation declarationsSebastian Huber1-0/+4
The context validation support functions _CPU_Context_validate() and _CPU_Context_volatile_clobber() are used only by one test program (spcontext01). Move the function declarations to the CPU port implementation header file.
2018-01-25Remove make preinstallChris Johns1-0/+0
A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.
2017-07-25sparc: Add lazy floating point switchSebastian Huber1-0/+33
The SPARC ABI is a bit special with respect to the floating point context. The complete floating point context is volatile. Thus, from an ABI point of view nothing needs to be saved and restored during a context switch. Instead the floating point context must be saved and restored during interrupt processing. Historically, the deferred floating point switch was used for SPARC and the complete floating point context is saved and restored during a context switch to the new floating point unit owner. This is a bit dangerous since post-switch actions (e.g. signal handlers) and context switch extensions may silently corrupt the floating point context. The floating point unit is disabled for interrupt handlers. Thus, in case an interrupt handler uses the floating point unit then this will result in a trap (INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNIT). In uniprocessor configurations, a lazy floating point context switch is used. In case an active floating point thread is interrupted (PSR[EF] == 1) and a thread dispatch is carried out, then this thread is registered as the floating point owner. When a floating point owner is present during a context switch, the floating point unit is disabled for the heir thread (PSR[EF] == 0). The floating point disabled trap checks that the use of the floating point unit is allowed and saves/restores the floating point context on demand. Update #3077.

2016-11-18score: Move CPU_PER_CPU_CONTROL_SIZESebastian Huber1-1/+43
Move CPU_PER_CPU_CONTROL_SIZE and the optional CPU_Per_CPU_control to <rtems/score/cpuimpl.h> to hide it from <rtems.h>.
2016-11-10score: Move _CPU_Get_current_per_CPU_control()Sebastian Huber1-1/+9
Move _CPU_Get_current_per_CPU_control() from <rtems/score/cpu.h> to <rtems/score/cpuimpl.h>.

2016-11-07score: Add <rtems/score/cpuimpl.h>Sebastian Huber1-10/+15
The aim of this file is to encapsulate CPU port implementation details. This helps to hide implementation details from <rtems.h> which indirectly includes <rtems/score/cpu.h>.

2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-2/+0
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.
