We're just beginning our investigation by reviewing the available interfaces and assessing how to use them in a potential in-tree test. We would be happy to discuss this further during the testing quality meeting on June 27th, or sooner via email. We'll reach out once we have some ideas to propose and discuss. > If others are working on measuring, testing, or reducing boot time, please > consider joining the "Embedded and IOT" micro-conference at Plumbers in September. > > One of the chief topics of that micro-conference will be boot time.
