| | | | | | | | | | | | | | | | | | | | | | | | | | | | * Mega patch merge to change the format of the object IDs to loosen the dependency between the SCORE and the various APIs. There was considerable work to simplify the object name management and it appears that the name_table field is no longer needed. This patch also includes the addition of the internal mutex which is currently only used to protect some types of allocation and deallocation. This significantly can reduce context switch latency under certain circumstances. In particular, some heap/region operations were O(n) and had dispatching disabled. This should help enormously. With this merge, the patch is not as clean as it should be. In particular, the documentation has not been modified to reflect the new object ID layout, the IDs in the test screens are not updated, and _Objects_Get_information needs to be a real routine not inlined. As part of this patch a lot of MP code for thread/proxy blocking was made conditional and cleaned up. * include/rtems.h, inline/rtems/rtems/region.inl, macros/rtems/rtems/region.inl, src/dpmem.c, src/dpmemcreate.c, src/msg.c, src/msgqcreate.c, src/part.c, src/partcreate.c, src/ratemon.c, src/ratemoncreate.c, src/region.c, src/regioncreate.c, src/regiondelete.c, src/regionextend.c, src/regiongetinfo.c, src/regiongetsegment.c, src/regiongetsegmentsize.c, src/regionident.c, src/regionreturnsegment.c, src/rtemstimer.c, src/sem.c, src/semcreate.c, src/taskcreate.c, src/taskident.c, src/tasks.c, src/timercreate.c: Modified as part of above.

| | | | | | | | | | | * Per PR147 addressed problems when reseting and inserting a timer into a timer chain that did not honor time passage since the last time the timer server was scheduled and the new insertion. * include/rtems/rtems/timer.h, src/timerreset.c, src/timerserver.c, src/timerserverfireafter.c, src/timerserverfirewhen.c: Broke up the "reset server" routine into a set of very specific routines that allowed the server to be unscheduled, timer chains to be "synchronized" with the current time before inserting a new timer.

| | | | | | | | | | * Fixed bug where resetting a timer that was not at the head of one of the task timer chains resulted in the Timer Server task waking up too far in the future. * Added rtems_timer_get_information() directive to support testing. * src/timerserver.c, include/rtems/rtems/timer.h, * src/timergetinfo.c: New file. * src/Makefile.am: Modified to reflect above.

* Patch from Eric Norum <eric@cls.usask.ca> to implement this:Joel Sherrill2000-01-213-3/+7
| | | | | | | | | | | | | | | | | | | | I'd like to propose a change to RTEMS task variables that I think would make them more useful. I think that it is early enough in their existence to still make changes to their API. 1) Change type from `int' to `void *'. 2) Add extra argument to task_variable_add -- if non-NULL, a pointer to a `destructor' function to be called when the task exits. This function would be called with that task's value of the task variable as its argument. In many cases, the `dtor' function could be `free'. rtems_status_code rtems_task_variable_add ( rtems_id tid, void **ptr, void (*dtor)(void *)); rtems_status_code rtems_task_variable_delete (rtems_id tid, void **ptr); This would be all we'd need to cleanly and efficiently support C++ per-thread exception information without dragging in all that POSIX API stuff.

* POSIX message queues now include complete functionality includingJoel Sherrill2000-01-133-30/+31
| | | | | | | | | | | | | | | | blocking sends when the queue is full. The SuperCore was enhanced to support blocking on send. The existing POSIX API was debugged and numerous test cases were added to psxmsgq01 by Jennifer Averett. SuperCore enhancements and resulting modifications to other APIs were done by Joel. There is one significant point of interpretation for the POSIX API. What happens to threads already blocked on a message queue when the mode of that same message queue is changed from blocking to non-blocking? We decided to unblock all waiting tasks with an EAGAIN error just as if a non-blocking version of the same operation had returned unsatisfied. This case is not discussed in the POSIX standard and other implementations may have chosen differently.
* Added comment to indicate this path does not occur.Jennifer Averett2000-01-131-1/+2

* Added support for simple binary semaphores in addition to the highJoel Sherrill2000-01-055-15/+34
| | | | | | | | | | | | 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.
