FOSDEM 2020 - Microkernels and Component-based OS devroom CALL FOR PARTICIPATION The developers of several free and open-source microkernel-based operating systems will meet at FOSDEM 2020 [1] in Brussels, Belgium and will share a developer room. The devroom is currently looking for content in the form of talks and activities related to the area of microkernel-, unikernel-, and component-based operating systems. Possible topics include, but are not limited to: * introduction of a specific OS or framework * design of subsystems and the general architecture of an OS * used languages and tools * enabling support for hardware (architectures, device drivers) * enabling support for programming languages * maintenance and testing * security and robustness * trends and challenges * use cases, experiences, lessons learned and demos The deadline for your proposal is on December 1, 2019. Please use the Pentabarf [2] system to submit your proposals. You do not need to create a new account if you already have one. Make sure to include the following in your proposal: * title of your talk (will be printed in the FOSDEM booklet) * your full name (will be printed in the FOSDEM booklet) * a short abstract (one or two paragraphs) * duration of your talk (at least 25 and no longer than 55 min) The official devroom schedule (along with the accepted talks) will be announced on December 15 on the devroom's mailing list [3] and the speakers will be notified via e-mail. The schedule will also be published on the FOSDEM website. You are invited to send any other suggestions for what you want to see or do at the devroom to the list. We will also use this list to organize the traditional devroom dinner that will happen on the first day of FOSDEM. About the devroom Since the first Microkernel devroom at FOSDEM 2012, this devroom has been part of each following FOSDEM. The focus gradually widened to include component-based operating systems. By now it has become a somewhat institutionalized tradition for the community to meet there; to this date over a dozen projects have participated in one way or another. Each of the projects face similar challenges but come up with partially different solutions. Therefore, the goal of the devroom is to bring the various projects together, let them exchange ideas, cross-pollinate and socialize. Social events It also has become a habit that the microkernel projects dine together somewhere in Brussels. The year 2020 will not be any different, so there is going to be a dinner on Saturday night. We try place a reservation, so we will inform you about the exact location and time later. Consult the FOSDEM web and other projects for additional social events such as the famous FOSDEM-organized Friday Beer Event and the FOSDEM-arranged free sightseeing tours for spouses. About FOSDEM FOSDEM is a two-day event organised by volunteers to promote the widespread use of free and open source software. Taking place in the beautiful city of Brussels (Belgium), FOSDEM is widely recognised as the best such conference in Europe. FOSDEM covers a wide spectrum of free and open source software projects, and offers a platform for people to collaborate. To this end, FOSDEM has set up developer rooms (devrooms) with network/internet connectivity and projectors where teams can meet and showcase their projects. Devrooms are a place for teams to discuss, hack and publicly present latest directions, lightning talks, news and discussions. Besides developer rooms, FOSDEM also offers main tracks, lightning talks, certification exams and project stands. Every year, FOSDEM hosts more than 5000 developers at the ULB Solbosch campus. Participation and attendance is totally free, though the organisers gratefully accept donations and sponsorship. No registration necessary. Important dates recap * 2019-12-01: Deadline for submissions * 2019-12-15: Schedule published and speakers notified of acceptance * 2020-02-01: Devroom Dinner (details to be announced) * 2020-02-01/2020-02-02: The devroom takes places (check the schedule) Links [1] https://fosdem.org/ [2] https://penta.fosdem.org/submission/FOSDEM20 [3] https://lists.fosdem.org/listinfo/microkernel-devroom

depot_autopilot, log/serial, docker and reboots
by Roman Iten 03 Oct '19

03 Oct '19

Hello For continuous testing, I have a docker container in which the depot_autopilot run script is executed. For ARM targets, I include `log/serial` which executes `picocom`. It works like a charm until the point where the run script reboots the target and tries to reconnect to the serial port which is still busy. `ps` reaveals that picocom is still running, although it should have been killed by then. Please note that this only happens when the run script is executed within a docker container... After tinkering around with it, I came up with this patch [1]. It works for me when executing the run script "directly" as well as within the docker container. But to be honest, I don't understand why (...it's only required in a docker environment). I'd feel better if someone can confirm that the patch is reasonable or how else to solve the problem. Thanks, Roman [1] https://github.com/rite/genode/commit/c4c7bf56230d18480d672ba432d6958ff72ec…
