FreeBSD mini-Developer Summit, January 2020

Brussels, Belgium. January 31, 2020

This invitation-only FreeBSD Developer Summit takes place on Friday, January 31 2020 (the day before FOSDEM), located in Brussels, Belgium. FreeBSD committers are welcome to register themselves; non-committers have to be sponsored by a committer to attend.

FOSDEM 2020

FOSDEM 2020 takes place on February 1st and 2nd, 2020. Note that the FreeBSD mini-developer summit is organized independently from FOSDEM.

Travel Information

The FOSDEM Practical page has a lot of information about how to get to Brussels for FOSDEM.

Approaching the Event site

The DevSummit will be held in central Brussels at the Hotel NH Brussels Carrefour de l'Europe close to Brussels Centraal.

IRC

Note that many of attendees of the summit hang out on #devsummit on EFnet during the event (as well as the conference itself). Feel free to join!

Schedule

The current general plan is as follows.

(Do not edit this section yourself unless asked to.)

Presentations

Tell us about your latest project, brainstorm on solutions to a hard problem, train us to use a new tool, make observations about a FreeBSD development process and how to improve it, tell us how your company uses FreeBSD, or coordinate activities!

Submit your proposals to devsummit@freebsd.org and include a small abstract and number of slots needed. (1 slot = 20 minutes)

Working Groups

These sessions are intended to get developers with common areas of interest or specific projects in mind together for collaboration and hacking. They might involve prepared presentations, structured code reading, or a notebook-assisted whiteboard session. Advance preparation for such events is critical so everyone comes to the table with the right reading done so you can get to the meat of the matter.

Notes

If you are in trouble with preparing your slides, you could use the template attached to the page. It contains a LaTeX source file that you can modify to create PDF slides for the FreeBSD Developer Summit. It uses the Beamer class which is an easy-to-use extension to LaTeX for making presentations. You can easily install it by the following command (as root):

# pkg install latex-beamer

This will install Beamer and pdfLaTeX that can be used for compiling the sources to produce the desired PDF file.

$ pdflatex my-presentation.latex

Or you can use the LibreOffice / OpenOffice template (contributed by BaptisteDaroussin).

A few rule-of-thumbs when creating slides:

• Try to make things legible, use large fonts.
• Have title and closing.
• Use less text, you do not have to include everything on the slides. (Prepare and) Do a demonstration if needed.
• You have only a limited amount of time, having only 1 slide per minute (in addition to title and closing) is usually fine.
• Sometimes images can tell more than pure text.
• Discussions and meetings are the place where you might want to talk about the details.

Contact devsummit@FreeBSD.org if you have questions or problems.

Registration

In order to attend, you must register in advance, this allows us to size rooms, order food, provide beverages, and make dinner reservations. We appreciate your cooperation in letting us know your plans well in advance of the event. Non-committers must be sponsored by a committer in order to attend.

The meeting room and refreshments during the DevSummit will be sponsored. We collect a small fee from attendees to help cover the costs. The dinner will have to be paid by the attendees themselves (at the dinner).

Here is a list of the attendees and their guests at the summit.

Developer Attendees

(Please keep sorted alphabetically by last name. Do not change the format unless asked to.)

Guest Attendees

Developers are welcome to invite guests to attend the developer summit, subject to their tolerance for ceaseless hours of kernel hacking, and availability of space at the venue.

Discussion Notes

Notes during the summit are taken here: https://hackmd.io/5kQGpKJdTvqf758qwU8O9w

• Introductions & small announcements

• Talks:
  • Morning:
  • Google Summer of Code 2020 ideas brainstorming
  • Afternoon

    • Ports <-> src discussion (have, need, want)

      • Items most needed:
        • User management
        • Network management
    • Graphics (afternoon)
      • Things that need help updating:
        • OpenGL
        • X server
• Hacking groups

GSoC 2020 idea brainstorming

• KPI to use epoch to safely resize arrays (jtl)
• Add support for splash screens to vt (manu knows someone who could mentor)
• Explore a ABI/KBI conformance testing tool (imp)
• libpf (kp)
• System configuration from the desktop

  • Firewall configuration tool for desktops (backends for BSD firewalls, i.e. pf) -> ade

• Fully integrate MINIMAL kernel config into installer to replace GENERIC. Add missing devices and missing 'decoration' of drivers to allow them to be used with devmatch. devmatch may need to be enabled / run on installer images. (imp)
• Create a multiplexed tty device to allow /dev/console to be connected to multiple tty devices. This would allow multicons to extend beyond end of the kernel messages into the running of /etc/rc (imp)

• Desktop installation option in the installer (feel free to commendeer https://reviews.freebsd.org/D11841)

• Make evdev react (make it smarter) to events like pluggins in an external monitor (zeising)
• libifconfig (thj)
• Reimplement make xdev targets for using the host's clang. Currently it creates 'cc', 'as', etc that are used for port build. With gcc 4.2.1, we had to build separate binaries for each because gcc didn't really support multiple targets. clang supports multiple targets, so this would be shell script generation and moving the bits of clang (binaries, libraries, etc) into the chroot. We use this today to build arm and mips64 packages on amd64. What's there today is a poor match to clang and has a build time that's too long. (imp)
• Jail support for libcontainerd (pizzamig, mmokhi)
• Bluetooth audio integration (hsp)
• Bluetooth UI
• Integrating bhyve into vagrant
• UI for wifi configuration (extend bsdconfig)
• HDMI audio setup program

• Pick up a big port from the WantedPorts wiki page to port

• Help enhance CI infrastructure
• Make I2C touchpad work
• Chasing intel wireless chipset/firmware install (it's a trap!, bz)
