What's the impact of scheduler 'fifo' and priority '10' in the systemd service file?

I'm not able to start cdsp as a service on an Odroid C2 board running Armbian. The same ExecStart command works from the command line but fails when used in the service file.

I've tracked this down to the two options

CPUSchedulingPolicy=fifo
CPUSchedulingPriority=10

(with those commented out, the service starts and cdsp seems to work just fine) and Armbian kernel being compiled with option

CONFIG_RT_GROUP_SCHED=y

Now, before going down the rabbit hole that is compiling a custom kernel configuration for an SBC, I was wondering what will I miss without explicitly setting scheduler and priority for cdsp.

Thank you for your support and regards

The service file is somewhat outdated, and I don't know yet what needs to change and how. For now, just remove these lines to use the defaults.
