Minutes
- question on cpu usage following a discussion with a car OEM
- Sang bum: reports on a discussion on cpu consumption he had with an OEM
- Gunnar: depends on types of ECU : ic or infotainment
- Matti: most of systems are very much loaded because as soon as a system has spare capacity OEMs swap to a smaller chip because it costs less
- device driver virtualization
- wiki page: https://at.projects.genivi.org/wiki/x/ZpT0
- Matti: posted one hour ago a short intro on virtio in the above page
- report on review comments on the wiki page postponed to next week
- use cases discussion
- Sang bum: starts with a question about the use of Android os environment
- Gunnar: Android has been used for several years w/o support asked from google and w/o certification in mind, now some oems are engaging more closely with Google and look for approval
- Matti: agrees with Gunnar, Google is heavily pushing their techno into automotive and they will likely agree with the utilization of hypervisors
- Sang bum: asked whether there is a need to dynamically load an OS (i.e. load android when you want to run an android application)
- Sriram: this is an interesting requirement
- Franz: multiplying OSes make things more complex when executing the project (3/4 parties need to manage the project which makes it difficult)
- Matti: this cannot happen with Apple iOS because Apple has never offered iOS on an hw not designed by them
- Matti: all other OSes could be loaded on demand, Windows might become something people would like to have, a rear set entertainment is not really automotive, it is rather a tablet, this is why Windows could come back in the landscape
- [not captured for a couple of minutes]
- back on use cases

- Nikola: comments on the challenges column of the table, some challenges are relevant to architecture rather HV technologies, would it be worth identifying them better ?
- Sriram: yes, this would help
- Sriram: shows diagram on architecture at the bottom of the page
- Sang bum: how can SoCrun both linux and rtos w/o virtualization ?
- Sriram: this is because modern silicon offered the ability to specialize cores [capture is TBC], almost all infotainement systems were following this architecture up to now, but this is changing
- Sriram will share more diagrams
- AOB
- Technical summit - Fall 2018 (week starting on October 8, location: Bangalore, India)
- Philippe: informs the group that the topics selected for discussion in the summit are related to graphics sharing and hypervisors
- Sriram: coins the idea of inviting xviser, an HV open source project whose maintainer is based in Bangalore, can reach out to him for a possible presentation, link: http://xhypervisor.org/
- Franz: what are the results we need to talk about ?
- Gunnar: [not captured]
- Kai: what would be the prerequisites to deliver a demo there ?
- /TODO/ Philippe gather and provide info about the session schedule and space for demos at the Technical Summit
- Adjourned: 11:05am CET
- next week
- review of Opensynergy inputs on virtual device drivers
June 5
