Gregory Nutt cfb876263a SMP: There were certain conditions that we must avoid by preventing releasing the pending tasks while withn a critical section. But this logic was incomplete; there was no logic to prevent other CPUs from adding new, running tasks while on CPU is in a critical section. ... This commit corrects this. This is matching logic in sched_addreadytorun to avoid starting new tasks within the critical section (unless the CPU is the holder of the lock). The holder of the IRQ lock must be permitted to do whatever it needs to do.		2016-12-27 08:49:07 -06:00

Make.defs	sem_setprotocol: Handle a case of missing proxy for sem_setprotocol. Reorder so that (1) this error is avoided, and (2) >No proxy is needed if priority inheritance is not enabled.	2016-11-03 18:51:38 -06:00
sem_destroy.c	Remove some empty file section section header comments	2016-02-17 17:38:39 -06:00
sem_holder.c	Add pthread_mutexattr_get/set_protocol and non-standard sem_get/set_protocol. These may use to enable or disable priority inheritance on a single semaphore.	2016-11-02 09:05:18 -06:00
sem_initialize.c	sem_tickwait(): Add a new, non-standard function to perform timed semaphore waits. It is functionally equialent to the standard sem_timedwait(), but more efficient for use in higher performance device drivers. Requested by Max Neklyudov	2015-08-01 07:31:09 -06:00
sem_post.c	Add some comments.	2016-11-05 09:44:29 -06:00

sem_trywait.c	sem_wait() and sem_trywait() no longer modify the errno value UNLESS an error occurs. This allows these functions to be used internallly without clobbering the errno value.	2016-11-09 07:01:49 -06:00
sem_wait.c	Grrr... cloned typos!	2016-12-10 09:45:55 -06:00

semaphore.h	Within the OS, when a thread obtains a semaphore count it must call sem_addholder() if CONFIG_PRIORITY_INHERITANCE is enabled. If a count is available, then sem_wait() calls sem_addholder(), otherwise it waited for the semaphore and called sem_addholder() when it eventually received the count.	2016-10-26 07:23:15 -06:00
