First working version of klitirqd. 2011-02-13T01:42:53+00:00 Glenn Elliott gelliott@cs.unc.edu 2011-02-13T01:42:53+00:00 08b72aceacca166015d518738f9e300546b969ef Tasklets can be scheduled to klitirqd daemons when provided a real-time task "owner". A klitirqd kernel thread will assume the priority of the owner and will execute the provided tasklet when the kernel thread is scheduled by Litmus. See litmus_softirq.h for interface and limitations.

fdso: pass userpsace config argument to object constructor 2011-02-01T21:53:21+00:00 Bjoern B. Brandenburg bbb@cs.unc.edu 2011-01-29T20:50:52+00:00 7f0bd4c213ff8dca0eb3bdd887f5c62c8d30fab5 As Glenn pointed out, it is useful for some protocols (e.g., k-exclusion protocols) to know the userspace configuration at object creation time. This patch changes the fdso API to pass the parameter to the object constructor, which is then in turn passed to the lock allocater. The return code from the lock allocater is passed to userspace in return. This also fixes some null pointer dereferences in the FDSO code found by the test suite in liblitmus.
