[SOLVED] CPUset not working in Ubuntu 22.04

[Snoopy8]

I've had it working on Raspberry Pi OS and SO 1.2.x but struggled to convince myself there was any benefit   . Maybe on Ubuntu...? I'll add it to my list.

Please have a read of this

Some people have reported a SQ improvement by enabling cpusets but for others, it made no difference. The intent here is to isolate the music processes from system processes. I took it further.

However, I have returned to the simple SO way because something wrong when I recently changed hardware to an Intel NUC Element and Ubuntu versions.

I have found that Cpuset is particularly useful when there is a Real Time (RT) kernel in use. The combination of cpusets and RT kernel has given a maximum latency (measured using Cyclictest) of around 10 milliseconds, spread evenly across 4 CPUs. The result is better SQ. My challenge is to apply what I have done with Ubuntu on the NUC to Ubuntu on a Pi. I suspect using Raspian is too far a leap?

Note that I am probably the craziest SO user here, even building my own RT kernel!!
