Sorry. At *best* it can say how many cycles it requires. The problem with what you say is that this does not correlate exactly to schedules. Also, the check you propose would need to be done in the IPC path, and it appears (to me) to be prohibitively expensive. We didn't look at this exactly, but at something closely related. shap _______________________________________________ L4-hurd mailing list [email protected] http://lists.gnu.org/mailman/listinfo/l4-hurd
