| |
Hi, I would like to have in a quad-core, 2 cores totally (100%) dedicated to RT tasks (SCHED_RR and SCHED_FIFO) and the other 2 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) echo 0-1 > /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 2,3) mkdir /dev/cgroup/1 echo 2-3 > /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
Is there anyway for doing this?
Thanks, Rol
