| * | score: add Inherited_priorities priority queue and functions | Gedare Bloom | 2018-03-23 | 1 | -2/+4 |
| | | | | | | | | | | Adds enqueue, dequeue, requeue, evaluate, and release functions for the thread priority node priority queue of inherited priorities. Add calls to these functions as needed to maintain the priority queue due to blocking, unblocking, and priority changes. Closes #3359. | ||||
| * | score: replace current and real priority with priority node | Gedare Bloom | 2018-03-23 | 1 | -6/+6 |
| | | | | | | | | | | Encapsulate the current_priority and real_priority fields of the thread control block with a Thread_Priority_node struct. Propagate modifications throughout the tree where the two fields are directly accessed. Updates #3359. | ||||

| | | | | | | | | | | | | | | * src/coremutex.c, src/coremutexseize.c, src/coremutexsurrender.c, inline/rtems/score/coremutex.inl: The per thread field resource_count should only be manipulated when a mutex is priority ceiling or priority inherit. This was reported by Chris Johns <ccj@acm.org> who also noticed that the use of switches for all disciplines generated less efficient code than using explicit tests for the one or two cases we were really interested in. Further review of his modifications made it apparent that the "isa" methods to test mutex discipline were not being used so this modification was swept into the code as well. | ||||

| * | Added support for simple binary semaphores in addition to the high | Joel Sherrill | 2000-01-05 | 1 | -22/+17 |
| | | | | | | | | | | | | | power binary/mutex style semaphores already supported by RTEMS. This was done at the request of Eric Norum <eric@cls.usask.ca> in support of his effort to port EPICS to RTEMS. This change consisted of changing the nesting_allowed boolean into a lock_nesting_behavior enumerated value as well as allowing the core mutex object to optionally support ensuring that the holder of a binary semaphore released it. Finally, a more subtle enhancement was to allow the non-holder to release a priority inheritance/ceiling mutex and still allow the holding task to return to its original priority. | ||||
