Hi there.

Havn't been around for a while. 

Just figured that some people are nagging Paul about my CPU isolation
recommendations. ;)

As a matter of fact that CPU0 isolation feature is currently not working
on the RPI4.

I am running latest RPiOS64, latest eeprom firmware, latest 5.10 kernel
(all git) . Which is quite a step 
ahead of pCP70. I got the same situation. 

However.

The key tweak is to attach the alsa output thread to a single CPU.
There's IMO no need to nail the main SL process and the other threads to
a single CPU. 
That's IMO even counterproductive.

cat /proc/interrupts

shows where the IRQs are speeding up.


I'll check with the RPi kernel folks what have changed.


@ Paul

since busybox top and ps are pretty useless, do you know a package that
holds a full "ps" version.

Thx.
