From 2d2352bab92c51c2fd857b9555242545bd08c95e Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 5 Jun 2013 11:48:57 +0200 Subject: score: Add and use _Objects_Put() Add and use _Objects_Put_without_thread_dispatch(). These two functions pair with the _Objects_Get() function. This helps to introduce object specific SMP locks to avoid lock contention. --- cpukit/libfs/src/pipe/fifo.c | 18 ++++++++++-------- 1 file changed, 10 insertions(+), 8 deletions(-) (limited to 'cpukit/libfs/src/pipe/fifo.c') diff --git a/cpukit/libfs/src/pipe/fifo.c b/cpukit/libfs/src/pipe/fifo.c index ba5e7b7e40..b8eed9b449 100644 --- a/cpukit/libfs/src/pipe/fifo.c +++ b/cpukit/libfs/src/pipe/fifo.c @@ -74,14 +74,16 @@ static rtems_id pipe_semaphore = RTEMS_ID_NONE; /* Set barriers to be interruptible by signals. */ static void pipe_interruptible(pipe_control_t *pipe) { - Objects_Locations location; - - _Barrier_Get(pipe->readBarrier, &location)->Barrier.Wait_queue.state - |= STATES_INTERRUPTIBLE_BY_SIGNAL; - _Thread_Enable_dispatch(); - _Barrier_Get(pipe->writeBarrier, &location)->Barrier.Wait_queue.state - |= STATES_INTERRUPTIBLE_BY_SIGNAL; - _Thread_Enable_dispatch(); + Objects_Locations location; + Barrier_Control *the_barrier; + + the_barrier = _Barrier_Get(pipe->readBarrier, &location); + the_barrier->Barrier.Wait_queue.state |= STATES_INTERRUPTIBLE_BY_SIGNAL; + _Objects_Put( &the_barrier->Object ); + + the_barrier = _Barrier_Get(pipe->writeBarrier, &location); + the_barrier->Barrier.Wait_queue.state |= STATES_INTERRUPTIBLE_BY_SIGNAL; + _Objects_Put( &the_barrier->Object ); } #endif -- cgit v1.2.3
