I seem to remember them switching to arm64 recently?

I think it would be helpful if someone with an RPi4 could do this.

For those of you who are able to try this, sounds like you just install
linuxcnc-uspace and then run latency-test. Also install/try latencytop,
although Linux CONFIG_LATENCYTOP is not enabled in Debian probably.

$ apt-file search latency-test
linuxcnc-uspace: /usr/bin/latency-test
linuxcnc-uspace: /usr/share/doc/linuxcnc/examples/sample-configs/apps/latency/latency-test.demo
linuxcnc-uspace: /usr/share/man/man1/latency-test.1.gz
