Currently i am running SMVP mode (2 VPEs each having one TC) on MIPS 34Kc .
W.r.t load balancing logic, load_balance --> find_busiest_group (find the busiest group in the domain) --> find_busiest_queue (find the busiest runqueue among the cpus in group)
In SMVP mode, each VPE is referred as groups and these VPEs (groups) have *ONLY* one TC (CPU) so do we still need to run "find_busiest_queue" to get the busiest runqueue among the cpus of a particular group .
Instead of "find_busiest_queue" , can we use below code in "linux-188.8.131.52/kernel/sched.c" ,
+#ifdef CONFIG_MIPS_MT_SMP + cpu = cpumask_first(sched_group_cpus(group)) / * get the first CPU in the busiest group */
+ busiest = cpu_rq (cpu) /* assign the runqueue of the cpu to busiest */ +#else busiest = find_busiest_queue(group, idle, imbalance, cpus); +#endif
