litmus2008.git/kernel/sched_plugin.c, branch RTSS07 [ARCHIVE] Old LITMUS^RT 2008 version (for reference). First part of the PI semaphore implementation. 2007-05-14T21:41:58+00:00 Bjoern B.

Note: The plugins don't actually work yet, since the semantics of the
callbacks have changed. That will be fixed in the next patch.
Various changes that I don't want to lose, but the code does not work. 2007-05-09T20:44:29+00:00 John M. Calandrino jmc@jupiter-cs.cs.unc.edu 2007-05-09T20:44:29+00:00 a0615764712672e852ee44aabfaaaa0911f4a7c3

PI semaphores now use scheduler callbacks to update priority on a down or
up call. Issues with calling down/up and not calling __down_failed or
__up_wakeup for PI semaphores has been noted (since priority-related things
occured in those calls) and up has been fixed (down is in process).
Callbacks are now responsible for the priority checks and
updates, and some subtle cases are handled that were missed before. Still
need to finish handling GSN-EDF implementation issues related to suspensions.

Add scheduler plugin callbacks for priority inheritance.

the TRACE ring-buffer.
