Hi,
The RT-patched kernel 2.6.25.4-rt6 doesn't build if you've turned on group scheduling but not SMP, owing to this bit of code in kernel/sched_rt.c:
#if defined CONFIG_SMP || defined CONFIG_RT_GROUP_SCHED if (rt_se_prio(rt_se) < rt_rq->highest_prio) { struct rq *rq = rq_of_rt_rq(rt_rq); rt_rq->highest_prio = rt_se_prio(rt_se);
if (rq->online) cpupri_set(&rq->rd->cpupri, rq->cpu, rt_se_prio(rt_se)); } #endif
struct rq only has "cpu" and "online" elements if CONFIG_SMP is enabled.
My full config is here: http://offog.org/stuff/config-2.6.25
Thanks,
