The description on tracing workloads from medical devices WG should be taken and applied to the Automotive WG. Describe the needed steps ho to setup the traces. Create tickets for non-working parts and report to medical-devices WG. (Shuah will do upstream of improvements.) Create example traces for further disucssion.

Tracing overall is possible with the latest qemu image. Example was done during the automotive WG meeting today. Read the minutes for the stress-ng trace using strace: https://lists.elisa.tech/g/automotive/message/626
