This session presents a proposal for a Safety Test framework in U-Boot. We use the ongoing integration effort of a Built-In Self Test (BIST) driver as an example and dive into the challenges we face during upstreaming it. In systems with heterogeneous SoCs such as the Texas Instruments (TI) K3 family, U-Boot may be required to bootstrap not just Linux running cores but also other MCUs running safe operating systems. Running safety tests on these cores would mean drivers execute safety diagnostics both triggering HW tests e.g. BIST, POST, JTAG etc. as well as SW e.g. STLs and SDLs prior to booting the MCU. At present, lack of a clear, dedicated subsystem leads to categorizing safety-related drivers under misc/. While this is a convenient approach, it may not be scalable as safety use-cases and applications increase.

The need of such a framework would be inevitable following the increase in safety-driven automotive systems. It could become a useful precursor to enabling ELISA systems and starting safe RTOSes. It would also benefit systems using Linux ecosystems such as RedHat's In-Vehicle Operating System (RHIVOS). A Safety Test uclass framework would be proposed in this session.
