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.

sem_destroy.c

Remove some empty file section section header comments

sem_holder.c

A few cosmetic changes

2017-03-11 08:58:42 -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

sem_post.c

Add some comments.

2016-11-05 09:44:29 -06:00

sem_recover.c

nuttx/sched: Replace irqsave() with enter_critical_section(); replace irqrestore() with leave_critical_section()

2016-02-14 08:17:46 -06:00

sem_reset.c

Update some comments

2016-03-06 13:50:26 -06:00

sem_setprotocol.c

Missing # on endif

2016-11-03 21:27:52 -06:00

sem_tickwait.c

nuttx/sched: Replace irqsave() with enter_critical_section(); replace irqrestore() with leave_critical_section()

2016-02-14 08:17:46 -06:00

sem_timedwait.c

Move cancellation point definitions to their own header file.

2016-12-10 09:08:26 -06:00

sem_timeout.c

nuttx/sched: Replace irqsave() with enter_critical_section(); replace irqrestore() with leave_critical_section()

2016-02-14 08:17:46 -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

Cancellation points: Fix some backward logic in conditional compilation.

2017-02-02 06:42:41 -06:00

sem_waitirq.c

nuttx/sched: Replace irqsave() with enter_critical_section(); replace irqrestore() with leave_critical_section()

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.

spinlock.c

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.
