* sparc: Fix context switch on SMPDaniel Cederman2015-11-171-17/+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. Close #2472.

* bsp/leon3: Fix Termios context usageSebastian Huber2015-10-201-8/+3

* Beaglebone: fix missing clobber in inline assembly.Marcos Diaz2015-09-101-1/+7
| | | | | | | | flush_data_cache uses R0 directly but doesn't list it as a clobbered register. Compiling with -O3 made this code break, since the function that calls flush_data_cache already uses r0. closes #2416.

| | | | | | | | there is no need to define access macros for field covering whole registers. In addition, BSP_FLD32 does not work right for field 32bit length. Signed-off-by: Premysl Houdek <kom541000@gmail.com>

* bsp/tms570: fix get time resolution after infrastructure change to timecounter.Pavel Pisa2015-07-161-6/+35
| | | | | | | | | | | | | | | | | The update fixes breakage of TMS570 support after Alexander Krutwig switch of RTEMS time read to timecounter mechanism bsps: Convert clock drivers to use a timecounter Mechanism to specify odd (non 1 Mhz) time base update frequencies implemented after objections of Martin Galvan. Code is adjusted to convert RTEMS configuration parameter microseconds_per_tick to such odd base if TMS570_PREFERRED_TC_FREQUENCY is specified appropriately.

| | | | | | | | Add rtems_interrupt_local_disable|enable() as suggested by Pavel Pisa to emphasize that interrupts are only disabled on the current processor. Do not define the rtems_interrupt_disable|enable|flash() macros and functions on SMP configurations since they don't ensure system wide mutual exclusion.

* 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.
* score: Add Thread_Control::is_fpSebastian Huber2015-06-091-17/+1
| | | | | | | | Store the floating-point unit property in the thread control block regardless of the CPU_HARDWARE_FP and CPU_SOFTWARE_FP settings. Make sure the floating-point unit is only enabled for the corresponding multilibs. This helps targets which have a volatile only floating point context like SPARC for example.
