rtems: Do not switch off the FP attribute This is necessary after commit 335e5caa9a9e0f28acf94fe4c2871017fcd71794.
7:56 AM Changeset in rtems [f718e79]4.11 by Sebastian Huber <sebastian.huber@…>
Revert "timecounter: No _Timecounter_Tick_simple() for SMP" This reverts commit 46ae1d7a2b49b8f973dd6ba44fbbd38383798524. The _Timecounter_Tick_simple() function actually doesn't switch to the next timehand, so it is all right to use the simple timecounter approach even on SMP configurations. The use of simple timecounters is not recommended however since they impose a performance penalty.
4:41 AM Changeset in rtems [4d0ade9] by Konstantin Belousov <kib@…>
timecounter: Merge FreeBSD change r284256 Tweaks for r284178: Do not include machine/atomic.h explicitely, the header is already included by sys/systm.h. Force inlining of tc_getgen() and tc_setgen(). The functions are used more than once, which causes compilers with non-aggressive inlining policies to generate calls. Suggested by: bde Sponsored by: The FreeBSD Foundation MFC after: 1 week Update #3175.

score: Fix compiler memory barriers for atomic ops
11:49 AM Changeset in rtems [e1d61fe]4.11 by kib <kib@…>
timecounter: Synchronize with FreeBSD When updating/accessing the timehands, barriers are needed to ensure that: - th_generation update is visible after the parameters update is visible; - the read of parameters is not reordered before initial read of th_generation. On UP kernels, compiler barriers are enough. For SMP machines, CPU barriers must be used too, as was confirmed by submitter by testing on the Freescale T4240 platform with 24 PowerPC processors.

fixed: [a51b3526eac244db59ccdf582e1921ddcd969e5c/rtems] PSR.EF is cleared for the interrupt handlers. On SMP configurations the FP context is saved/restored around the _Thread_Dispatch() call in the interrupt exit code. On uni-processor configurations post-switch actions (e.g. signal handlers) and context switch extensions may silently corrupt the floating point context.

rtems: Change CONTEXT_FP_SIZE define Define CONTEXT_FP_SIZE to zero in case hardware and software floating point support is disabled. The problem is that empty structures have a different size in C and C++. In C++ they have a non-zero size leading to an overestimate of the workspace size.
7:43 PM Changeset in rtems [335e5ca]4.11 by Sebastian Huber <sebastian.huber@…>
score: Add Thread_Control::is_fp 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.

3:48 PM Changeset in rtems [a51b352]4.11 by Sebastian Huber <sebastian.huber@…>
sparc: Add SPARC_USE_SAFE_FP_SUPPORT 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.

tmtests/tm26: Fix context switch to FP task It is wrong to restore the floating point context here. The _Context_Switch() ends up in _Thread_Handler() which will call _Thread_Restore_fp(). In _Thread_Do_dispatch() the FP restore is after the context switch.
