From 23350dd1f55e20a596f9e469feca743c7fe997ec Mon Sep 17 00:00:00 2001 From: deischen Date: Tue, 22 Apr 2003 20:28:33 +0000 Subject: Add a couple asserts to pthread_cond_foo to ensure the (low-level) lock level is 0. Thus far, the threads implementation doesn't use mutexes or condition variables so the lock level should be 0. Save the return value when trying to schedule a new thread and use this to return an error from pthread_create(). Change the max sleep time for an idle KSE to 1 minute from 2 minutes. Maintain a count of the number of KSEs within a KSEG. With these changes scope system threads seem to work, but heavy use of them crash the kernel (supposedly VM bugs). --- lib/libpthread/thread/thr_private.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'lib/libpthread/thread/thr_private.h') diff --git a/lib/libpthread/thread/thr_private.h b/lib/libpthread/thread/thr_private.h index 87bc05a..a554796 100644 --- a/lib/libpthread/thread/thr_private.h +++ b/lib/libpthread/thread/thr_private.h @@ -215,6 +215,7 @@ struct kse_group { struct sched_queue kg_schedq; /* scheduling queue */ struct lock kg_lock; int kg_threadcount; /* # of assigned threads */ + int kg_ksecount; /* # of assigned KSEs */ int kg_idle_kses; int kg_flags; #define KGF_SINGLE_THREAD 0x0001 /* scope system kse group */ @@ -1023,6 +1024,7 @@ void _kse_single_thread(struct pthread *); void _kse_start(struct kse *); int _kse_setthreaded(int); int _kse_isthreaded(void); +void _kseg_free(struct kse_group *); int _mutex_cv_lock(pthread_mutex_t *); int _mutex_cv_unlock(pthread_mutex_t *); void _mutex_lock_backout(struct pthread *); @@ -1060,7 +1062,7 @@ void _thr_lock_wait(struct lock *lock, struct lockuser *lu); void _thr_lock_wakeup(struct lock *lock, struct lockuser *lu); int _thr_ref_add(struct pthread *, struct pthread *, int); void _thr_ref_delete(struct pthread *, struct pthread *); -void _thr_schedule_add(struct pthread *, struct pthread *); +int _thr_schedule_add(struct pthread *, struct pthread *); void _thr_schedule_remove(struct pthread *, struct pthread *); void _thr_setrunnable(struct pthread *curthread, struct pthread *thread); void _thr_setrunnable_unlocked(struct pthread *thread); -- cgit v1.1
