error: "Invalid argument" setting key "kernel.sched_rt_runtime_us"
Issue
default value for sched_rt_runtime_us kernel parameter is
kernel.sched_rt_runtime_us = 950000
when i am changing the value to 700000 i am getting following message ( while lowering value from default )
# sysctl -w kernel.sched_rt_runtime_us=700000
error: "Invalid argument" setting key "kernel.sched_rt_runtime_us"
when i am increasing the value it is working fine
# sysctl -w kernel.sched_rt_runtime_us=980000
kernel.sched_rt_runtime_us = 980000
How do we change the value of above parameter value (lower the value)?
