Safety Certification Challenges

From Xen
Revision as of 10:53, 6 April 2018 by Lars.kurth (talk | contribs)

This page captures the efforts to certify Xen on ARM for ISO 26262 ASIL B. Discussions happen during the regular Xen on ARM Community Calls organized on xen-devel by Stefano Stabellini and Julien Grall. See [1] for Minutes.

We have identified the following requirements, all of them need an owner:

  • Code style requirements, a subset of MISRA
  • Next step: find public documents that describe the code style requirements and publish them to xen-devel.
  • Create a subset of functions that need to go through certification
  • Next step: create a small Kconfig for Xen as a reference, using Renesas Rcar as starting point.
  • Start a discussion on which features we need to have. For instance real time schedulers might be required in some configurations but not all.
  • Understand how to address dom0:
  • We need a plan for a non-Linux dom0. It looks like FreeRTOS could be a good option.
  • Next step: Find out more information about FreeRTOS on Xen. Reach out to people that worked on it (Dornerworks? Galois?).
  • Create artifacts, such as docs, fault analysis, prove fault tolerance, safety management docs, document development processes.
  • Next step: find a company or a certification body that would guide us through the process.
