Tool/software:
Hi,
I am currently working on AM64x Linux_RT, I am looking to have very deterministic task scheduling and deadline handling. After browsing a bit, I got to know that sched_deadline serves my purpose. But when i try to set the CPU affinity by following through online references from Linux foundation, I don't have cpuset option in /sys/fs/cgroup.
Can you please tell me how i could achieve CPU affinity such that, i fix specific tasks to particular CPU on AM64x.
For reference, i got this slide from Linux Foundation.org
Giving SCHED_DEADLINE Affinity
cd /sys/fs/cgroup/cpuset
mkdir my_set
mkdir other_set
echo 0-2 > other_set/cpuset.cpus
echo 0 > other_set/cpuset.mems
echo 1 > other_set/cpuset.sched_load_balance
echo 1 > other_set/cpuset.cpu_exclusive
echo 3 > my_set/cpuset.cpus
echo 0 > my_set/cpuset.mems
echo 1 > my_set/cpuset.sched_load_balance
echo 1 > my_set/cpuset.cpu_exclusive
echo 0 > cpuset.sched_load_balance
Thank you in advance.
Solomon
