From 7fe6d60bf08df975c395515074c85976d9e4e3fb Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Fri, 15 Jul 2022 09:16:04 +0200 Subject: score: Remove PRIORITY_PSEUDO_ISR thread priority The uniprocessor schedulers had some special case logic for the PRIORITY_PSEUDO_ISR priority. Tasks with a priority of PRIORITY_PSEUDO_ISR were allowed to preempt a not preemptible task. If other higher priority task are made ready while a PRIORITY_PSEUDO_ISR task preempts a not preemptible task, then the other tasks run before the not preemptible task. This made the RTEMS_NO_PREEMPT mode ineffective. Remove the PRIORITY_PSEUDO_ISR special case logic. This simplifies the uniprocessor schedulers. Move the uniprocessor-specific scheduler support to the new header file . Close #2365. --- cpukit/rtems/src/timerserver.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'cpukit/rtems') diff --git a/cpukit/rtems/src/timerserver.c b/cpukit/rtems/src/timerserver.c index 5d863bd79c..e5242c82a5 100644 --- a/cpukit/rtems/src/timerserver.c +++ b/cpukit/rtems/src/timerserver.c @@ -173,7 +173,7 @@ static rtems_status_code _Timer_server_Initiate( } if ( priority == RTEMS_TIMER_SERVER_DEFAULT_PRIORITY ) { - priority = PRIORITY_PSEUDO_ISR; + priority = PRIORITY_MINIMUM; } /* -- cgit v1.2.3
