* bsps/sparc: Fix link-time errorSebastian Huber2016-01-261-6/+0
| | | | Fix for commit 76ac1ee3bba2a20ded7ea12394af0a633be25ff9.
* score: Fix simple timecounter supportSebastian Huber2016-01-191-2/+7
| | | | Update #2502.
* bsps: Call bsp_work_area_initialize() earlySebastian Huber2015-12-103-59/+6
| | | | | | | | Call bsp_work_area_initialize() before bsp_start(). This allows bsp_start() to use malloc() etc. which is beneficial for systems with a plug-and-play hardware enumeration. Update #2408.
* bsps/sparc: Use default bsp_pretasking_hook()Sebastian Huber2015-12-101-26/+0
| | | | | | Move content to bsp_predriver_hook() functions of the BSPs. Update #2408.
* sparc: Fix context switch on SMPDaniel Cederman2015-11-161-17/+14
| | | | | | | | | | | | | | | | We must not load registers (e.g. PSR) from the heir context area before the heir stopped execution. With this patch the write to PSR is divided into two steps. We first update the current window pointer and then we restore the status registers and enable traps. This allows us to move the first write to PSR to be before the write to WIM, as there is now no risk that we get an interrupt where the CWP and WIM would be inconsistent. We only need to make sure that we do not use any of the non-global registers or instructions that affects CWP for three instructions after the write. In the earlier code the non-global %o1 register was used right after the write to PSR, which required the use of three nop:s.
* basdefs.h: Add and use RTEMS_UNUSEDSebastian Huber2015-10-261-1/+1

* SMP: Fix and optimize thread dispatchingSebastian Huber2015-09-281-13/+7
| | | | | | | | According to the C11 and C++11 memory models only a read-modify-write operation guarantees that we read the last value written in modification order. Avoid the sequential consistent thread fence and instead use the inter-processor interrupt to set the thread dispatch necessary indicator.
* score: Simplify <rtems/system.h>Sebastian Huber2015-06-261-0/+1
| | | | | Drop the <rtems/score/percpu.h> include since this file exposes a lot of implementation details.
* bsps/sparc: tlib clock driver timecounter supportSebastian Huber2015-06-091-38/+56

* sparc: Add SPARC_USE_SAFE_FP_SUPPORTSebastian Huber2015-06-091-0/+85
| | | | | | | | | | | | | | | | | | | | | | | | 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 is 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. On SMP configurations the deferred floating point switch is not supported in principle. So use here a safe floating point support. Safe means that the volatile floating point context is saved and restored around a thread dispatch issued during interrupt processing. Thus post-switch actions and context switch extensions may safely use the floating point unit. Update #2270.
