Are cpu.weight and io.bfq.weight mandatory?

What’s the content in /sys/fs/cgroup/site2/cgroup.controllers, /sys/fs/cgroup/cgroup.controllers, and site2/info/current/cgroup?

Happens because cgconfig isn’t valid until EditDomain --reconfig --all is run. Backend will attempt to create these controllers as needed.

What’s in site1/info/current/cgroup? A 0 weight isn’t valid at all.

Same for this. They will default to 100 which is balanced.

I believe it errors on None values, as I don’t usually set a specific value for weights leaving that to the panel to handle. Perhaps it doesn’t default to 100 for some reason when those are None?

Also, is there a good way to calculate proper values for those params?

Issue linked back to 5.x kernel. Kernels prior to 5.8 don’t export memory.stat top-level. A workaround is in place now to look at /proc/meminfo. Same situation for cpu.stat in these kernels, /proc/stat is used instead at a loss of precision.
