* score: Change Timestamp_Control to sbintime_tSebastian Huber2017-10-094-34/+43
| | | | | | | | The timestamp are based on the uptime. There is no need for a 64-bit seconds part. The signed 32-bit seconds part of the sbintime_t limits the uptime to roughly 68 years. Close #2740.
* score: Use struct timespec for TODSebastian Huber2017-10-094-57/+19
| | | | | | | Use the timestamps only for uptime based values. Use struct timespec for the absolute time values (TOD). Update #2740.
* score: Simplify _Timestamp_Add_to()Sebastian Huber2017-10-091-7/+1
| | | | Update #2740.
* posix: Implement self-contained POSIX mutexSebastian Huber2017-10-056-12/+43
| | | | | | | | POSIX mutexes are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3112.
* posix: Implement self-contained POSIX condvarSebastian Huber2017-10-052-2/+0
| | | | | | | | POSIX condition variables are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3113.
* posix: Implement self-contained POSIX rwlocksSebastian Huber2017-10-0510-133/+82
| | | | | | | | POSIX rwlocks are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3115.
* posix: Implement self-contained POSIX barriersSebastian Huber2017-10-052-2/+0
| | | | | | | | POSIX barriers are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3114.
* posix: Implement self-contained POSIX semaphoresSebastian Huber2017-10-054-60/+91
| | | | | | | | | | | | | | For semaphore object pointer and object validation see POSIX_SEMAPHORE_VALIDATE_OBJECT(). Destruction or close of a busy semaphore returns an error status. The object is not flushed. POSIX semaphores are now available in all configurations and no longer depend on --enable-posix. Update #2514. Update #3116.
* posix: Optimize pthread_once_tSebastian Huber2017-10-052-2/+2
| | | | | | Reduce size of pthread_once_t and make it zero-initialized. Update #3142.
* score: Make status codes unconditionalSebastian Huber2017-10-051-9/+2
| | | | | | | | The internal status codes encode a Classic rtems_status_code and error codes used by the POSIX and C11/C++11 APIs. In case the POSIX API is disabled, the C11/C++11 support must still work. Close #3167.
* score: Simplify red-black tree debug supportSebastian Huber2017-09-273-13/+17
| | | | | | | | Make the RBTree_Node layout independent of RTEMS_DEBUG (and all other build configuration options). This allows the use of this structure in Newlib. Update #3112.
* score: Rename to _Scheduler_ControlSebastian Huber2017-09-277-15/+15
| | | | | | | Rename struct Scheduler_Control to _Scheduler_Control to allow its use in standard header files, e.g. <pthread.h>. Update #3112.

* sparc: Add lazy floating point switchSebastian Huber2017-07-256-219/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* INTERNAL_ERROR_ILLEGAL_USE_OF_FLOATING_POINT_UNITSebastian Huber2017-07-251-1/+2

* sparc: Add assembly workaround for LEON3FT B2BST errataDaniel Cederman2017-07-173-0/+33
| | | | | | | | | | | | | | | This patch adds NOP instructions to prevent instruction sequences that are sensitive to the LEON3FT B2BST errata. See GRLIB-TN-0009: "LEON3FT Stale Cache Entry After Store with Data Tag Parity Error" for more information. The sequences are only modified if __FIX_LEON3FT_B2BST is defined. The patch works in conjunction with the -mfix-ut700, -mfix-gr712rc, and -mfix-ut699 GCC flags that prevents the sensitive sequences from being generated. Update #3057.
