Lines Matching full:preemption

59 preemption and interrupt disabling primitives. Contrary to other locking
60 mechanisms, disabling preemption or interrupts are pure CPU local
76 Spinning locks implicitly disable preemption and the lock / unlock functions
103 PI has limitations on non-PREEMPT_RT kernels due to preemption and
106 PI clearly cannot preempt preemption-disabled or interrupt-disabled
162 by disabling preemption or interrupts.
164 On non-PREEMPT_RT kernels local_lock operations map to the preemption and
200 local_lock should be used in situations where disabling preemption or
204 local_lock is not suitable to protect against preemption or interrupts on a
217 preemption or interrupts is required, for example, to safely access
235  - Preemption is not disabled.
244    Non-PREEMPT_RT kernels disable preemption to get this effect.
247    preemption enabled. The lock disables softirq handlers and also
248    prevents reentrancy due to task preemption.
253    avoid migration by disabling preemption.  PREEMPT_RT kernels instead
340 preemption. The following code sequence works perfectly correct on both
430 preemption. The following substitution works on both kernels::
466 preemption. On a PREEMPT_RT kernel this is achieved by acquiring the
473 Acquiring a raw_spinlock_t disables preemption and possibly also
486 preemption on PREEMPT_RT kernels::
