config. I've investigated a bit, and I've seen that cpu is only defined in struct rq on SMP kernel. So I think that you have a .config without SMP. To fix this problem, I propose this patch : Index: linux-2.6.23/kernel/sched_rt.c =================================================================== --- linux-2.6.23/kernel/sched_rt.c +++ linux-2.6.23/kernel/sched_rt.c 2007-10-27 11:04:08.000000000 -0400 @@ -18,19 +18,35 @@ static inline int rt_overloaded(struct rq *rq) { +#ifdef CONFIG_SMP return !cpus_empty(*rt_overload_mask(rq->cpu)); +#else + return !cpus_empty(*rt_overload_mask(0)); +#endif } static inline cpumask_t *rt_overload(struct rq *rq) { +#ifdef CONFIG_SMP return rt_overload_mask(rq->cpu); +#else + return rt_overload_mask(0); +#endif } static inline void rt_set_overload(struct rq *rq) { +#ifdef CONFIG_SMP cpu_set(rq->cpu, *rt_overload_mask(rq->cpu)); +#else + cpu_set(0, *rt_overload_mask(0)); +#endif } static inline void rt_clear_overload(struct rq *rq) { +#ifdef CONFIG_SMP cpu_clear(rq->cpu, *rt_overload_mask(rq->cpu)); +#else + cpu_clear(0, *rt_overload_mask(0)); +#endif } /* regards, trem - To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
