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/coretodset.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'cpukit/score/src/coretodset.c') diff --git a/cpukit/score/src/coretodset.c b/cpukit/score/src/coretodset.c index c265606137..4262cf32b6 100644 --- a/cpukit/score/src/coretodset.c +++ b/cpukit/score/src/coretodset.c @@ -30,7 +30,7 @@ void _TOD_Set_with_timestamp( uint32_t nanoseconds = _Timestamp_Get_nanoseconds( tod_as_timestamp ); Watchdog_Interval seconds_next = _Timestamp_Get_seconds( tod_as_timestamp ); Watchdog_Interval seconds_now; - ISR_Level level; + ISR_lock_Context lock_context; _Thread_Disable_dispatch(); @@ -41,9 +41,9 @@ void _TOD_Set_with_timestamp( else _Watchdog_Adjust_seconds( WATCHDOG_FORWARD, seconds_next - seconds_now ); - _TOD_Acquire( tod, level ); + _TOD_Acquire( tod, &lock_context ); tod->now = *tod_as_timestamp; - _TOD_Release( tod, level ); + _TOD_Release( tod, &lock_context ); tod->seconds_trigger = nanoseconds; tod->is_set = true; -- cgit v1.2.3
