Though now I've been confused by an offline question about affinity. Suppose we have some interrupt that has affinity to multiple cpus. E.g. (real example from one of my machines): # cat /proc/irq/94/smp_affinity_list 26,54 Now If I want to take either cpu26 or cpu54 offline - I'm guessing that I don't really need to find a new home for vector 94 - because the other one of that pair already has that set up. But your check_vectors code doesn't look like it accounts for that - if we take cpu26 offline - it would see that cpu54 doesn't have 94 free - but doesn't check that it is for the same interrupt. But I may be mixing "vectors" and "irqs" here. -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
