Signal sent from work_signal() may interrupt the low priority worker thread that is already running. For example, the worker thread that is waiting for a semaphore could be woken up by the signal and break any synchronization assumption as a result. It also does not make any sense to send signal if it is already running and busy. This commit fixes it.

Trivia fix to typo in comment
2016-10-26 12:29:36 -06:00

3e13ed2400
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.
...
This caused a problem when the thread calling sem_wait() was very low priority. When it received the count, there may be higher priority threads "hogging" the CPU that prevent the lower priority task from running and, as a result, the sem_addholder() may be delayed indefinitely.
The fix was to have sem_post() call sem_addholder() just before restarting the thread waiting for the semaphore count.
This problem was noted by Benix Vincent who also suggested the solution.

sched/pthread and task: When a pthread is started, there is a small bit of logic that will run on the thread of execution of the new pthread. In the case where the new pthread has a lower priority than the parent thread, then this could cause both the parent thread and the new pthread to be blocked at the priority of the lower priority pthread (assuming that CONFIG_PRIORITY_INHERITANCE is not selected).
...
This change temporarily boosts the priority of the new pthread to at least the priority of the new pthread to at least the priority of the parent thread. When that bit of logic has executed on the thread of execution of the new pthread, it will then drop to the correct priority (if necessary) before calling into the new pthread's entry point.
