Lines Matching full:barrier

14 require each architecture to have a full memory barrier after coming from
15 user-space, before updating rq->curr.  This barrier is implied by the sequence
16 rq_lock(); smp_mb__after_spinlock() in __schedule().  The barrier matches a full
17 barrier in the proximity of the membarrier system call exit, cf.
24 require each architecture to have a full memory barrier after updating rq->curr,
25 before returning to user-space.  The schemes providing this barrier on the various
28  - alpha, arc, arm, hexagon, mips rely on the full barrier implied by
31  - arm64 relies on the full barrier implied by switch_to().
33  - powerpc, riscv, s390, sparc, x86 rely on the full barrier implied by
34    switch_mm(), if mm is not NULL; they rely on the full barrier implied
