Hi, I would like to have in a quad-core, 1 core totally (100%) dedicated to RT tasks (SCHED_RR and SCHED_FIFO) and the other 3 cores with normal behavior, better said, allowing SCHED_OTHER & SCHED_FIFO & SCHED_RR tasks but still with a RT reservation. Follows an example: # Setup first domain (cpu 0,1,2) echo 0-2 > /dev/cgroup/0/cpuset.cpus echo 0 > /dev/cgroup/0/cpuset.mems # Setup RT bandwidth for firstdomain (80% for RT, 20% others) echo 1000000 > /dev/cgroup/0/cpu.rt_period_us echo 800000 > /dev/cgroup/0/cpu.rt_runtime_us # Setup second domain (cpu 3) mkdir /dev/cgroup/1 echo 3 > /dev/cgroup/1/cpuset.cpus echo 0 > /dev/cgroup/1/cpuset.mems # Setup RT bandwidth for second domain (100% for RT) echo 1000000 > /dev/cgroup/1/cpu.rt_period_us echo 1000000 > /dev/cgroup/1/cpu.rt_runtime_us # Setup RT bandwidth for third domain echo 1000000 > /dev/cgroup/1/0/cpu.rt_period_us echo 500000 > /dev/cgroup/1/0/cpu.rt_runtime_us # Setup RT bandwidth for fourth domain echo 1000000 > /dev/cgroup/1/1/cpu.rt_period_us echo 500000 > /dev/cgroup/1/1/cpu.rt_runtime_us root ----|---- | | (80% rt, 20% others 0 1 (100% rt @ core 3) @ cores 1,2,3) ------ | | 0 1 (50% rt for each group @ core 3) Is there anyway for doing this? Or must we have a separate /proc/sys/kernel/sched_rt_runtime_us & /proc/sys/kernel/sched_rt_period_us for each core/cpu? In this case: /proc/sys/kernel/sched_rt_runtime_us_0 /proc/sys/kernel/sched_rt_period_us_0 ... /proc/sys/kernel/sched_rt_runtime_us_n (n, cpu count) /proc/sys/kernel/sched_rt_period_us_n Thanks, Rol _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
