Typically, a SCHED_QUOTA thread with no runtime budget at the time of the request would be prevented from exiting. To address this issue, we demote threads receiving a cancellation request, which implies switching them out of primary mode, and moving to the weak scheduling class, where it cannot be held. --- kernel/cobalt/thread.c |2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/cobalt/thread.c b/kernel/cobalt/thread.c index d05482f..5bf8f39 100644 --- a/kernel/cobalt/thread.c +++ b/kernel/cobalt/thread.c @@ -1535,7 +1535,7 @@ check_self_cancel: return; } - __xnshadow_kick(thread); + __xnshadow_demote(thread); xnsched_run(); unlock_and_exit: ___ Xenomai-git mailing list Xenomai-git@xenomai.org http://www.xenomai.org/mailman/listinfo/xenomai-git
