Thunderbolt3 combines external USB3, PCIe, and DisplayPort peripherals into a converged interface. While the original intent was that OS-specific drivers would not be needed for peripherals to function, the reality is that a driver is needed to interact with the security features of the subsystem, flash firmware, and manage bandwidth and error handling. Additionally, the OS must provide robust PCI hotplug support in order to handle device arrival and departure.

This talk will present the architecture of the FreeBSD thunderbolt driver, the challenges faced with hot-plug, and the roadmap for future support, including USB4.

$Encouraging & enabling SMEs (small to medium enterprises) to contribute to BSD development -TomSmyth - Making use of the force multiplier of many hands make light work. - Tom Smyth talks about his experience using BSD as a small business owner. - Tom further explores the positive experience of supporting developers to achieve discrete real improvements in OpenBSD and related projects. - How small business can contribute to and shape BSD development. - Ideas about aggregating the resources of multiple small businesses to achieve an outcome that each small business individually could not afford - SMEs can reap 100% of the benefit by just committing a fraction of the cost. Can many hands and many pockets contribute to sustainable code development without burdening the projects that will have to maintain the code on an ongoing basis? This talk is an AMA format and propose a 15-20 minute talk and 30 minute Q & A session afterwards.$

$Thomas Johnson: Plumbing the Internet, BSD style BSDCan 2018 If you have ever delved into the world of BGP routing on the Internet, you know that it can be quite an undertaking. Fortunately, we can utilize BSD and a couple of open source tools to build a solution that will provide high availability and easy management, at a fraction of the cost of commercial solutions. This talk is an introduction to the basics of building a BGP presence on the Internet, and orchestrating it with Ansible. If you have ever delved into the world of routing on the Internet, you probably know that it can be daunting. You learned that BGP is the protocol used to build the global routing table, but likely discover that every answer leads to two more questions. Bureaucracy and expensive, proprietary solutions are everywhere. BSD cant stop the red tape, but it does offer a fantastic solution for your technical dilemma. This talk is a whirlwind tour of building an Internet presence in three parts (and an opportunity to learn from my mistakes). Act one is a brief introduction to the BGP protocol, the process to obtain numbering resources, and connectivity. The basics of rigging a FreeBSD host for routing are covered, and the routing daemon BIRD. Next up is discussion of network design for high-availability, and the FreeBSD/BIRD configuration to make it happen. Setting up one router may be fun, but were going to want automation. Enter Ansible. After a quick introduction, well use it to deploy a live demo of our configuration Finally, now that we have a fault-tolerant solution; so lets introduce some faults, and see what happens! Well induce some failures, and watch how our network responds. Time-permitting, I will wrap up with some discussion of resources for checking the status of your installation. Ill also discuss some more complex tasks, such as multi-site failover, and taking a router out of service. http://www.bsdcan.org/2018/schedule/events/985.en.html$
