What about intrd? It seems, this daemon does what we need -- supervision of the interrupt load and automatic reassignment of interrupts. However, it seems it is only part of OpenSolaris and not yet included in S10? Do you have any plans of integrating this in a future S10 update? Also, how exactly does intrd work? I.e, which interrupt routine(s) would be moved to a different cpu in my example? CPU 0 - Overall: 97.7% CPU 0 - Level 1: 15.9% CPU 0 - Level 6: 8.9% CPU 0 - Level 10: 71.9% Is the reassignment deterministic in any way? For example, are always lower-priority interrupts moved to different cpus first (in this example level 1 and 6 interrupts)? For our setup, we would want the clock interrupt to stay on cpu 0. And again: We urgently need a solution for this problem by early next year based on Solaris 10. Does anyone have an idea how to avoid interrupt overload in S10 (SPARC only)? Any help appreciated!
