pthread_setschedparam (SCHED_FIFO) without sched_rt_runtime_us = -1

Hello!
How can I set pthread_setschedparam (SCHED_FIFO) without changing sched_rt_runtime_us to -1?

See details at https://devtalk.nvidia.com/default/topic/1038742/pthread_setschedparam-sched_fifo-fails/

Thank you!

Could you try r32.2.1 and apply the rt patch to try.
Reference to below topic for the rt patches.

Thank you for the answer!
Unfortunately, applying the rt patch is not appropriate solition for us. Is there any other?

Unfortunately it’s native kernel issue I don’t have others solution now. But you can try r28.3 that kernel version is k4.4 should be without problem.
