From d50acdbb6c8213114ce887a56daea02697c9e1a1 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Mon, 10 Mar 2014 08:25:32 +0100 Subject: score: Add local context to SMP lock API Add a local context structure to the SMP lock API for acquire and release pairs. This context can be used to store the ISR level and profiling information. It may be later used to enable more sophisticated lock algorithms, e.g. MCS locks. There is only one lock that cannot be used with a local context. This is the per-CPU lock since here we would have to transfer the local context through a context switch which is very complicated. --- cpukit/score/src/coretodtickle.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'cpukit/score/src/coretodtickle.c') diff --git a/cpukit/score/src/coretodtickle.c b/cpukit/score/src/coretodtickle.c index c9f9597b1d..055b40c617 100644 --- a/cpukit/score/src/coretodtickle.c +++ b/cpukit/score/src/coretodtickle.c @@ -25,7 +25,7 @@ void _TOD_Tickle_ticks( void ) { TOD_Control *tod = &_TOD; - ISR_Level level; + ISR_lock_Context lock_context; Timestamp_Control tick; uint32_t nanoseconds_per_tick; @@ -37,7 +37,7 @@ void _TOD_Tickle_ticks( void ) /* Update the counter of ticks since boot */ _Watchdog_Ticks_since_boot += 1; - _TOD_Acquire( tod, level ); + _TOD_Acquire( tod, &lock_context ); /* Update the uptime */ _Timestamp_Add_to( &tod->uptime, &tick ); @@ -45,7 +45,7 @@ void _TOD_Tickle_ticks( void ) /* Update the current TOD */ _Timestamp_Add_to( &tod->now, &tick ); - _TOD_Release( tod, level ); + _TOD_Release( tod, &lock_context ); _TOD.seconds_trigger += nanoseconds_per_tick; if ( _TOD.seconds_trigger >= 1000000000UL ) { -- cgit v1.2.3
