For today's #ThankYouTuesday, I want to give a huge shout-out to @bsdtv and the entire audio/video team at the BSD Conferences.
Their work is fantastic and often happens behind the scenes, but it's always top-notch and absolutely essential.
Thank you so much - and see you in Zagreb!

Today is Monday, 1st September. And September means one thing: EuroBSDCon!
23 days to go until EuroBSDCon 2025 in Zagreb!
I’m doing a little “advent calendar” for BSD fans: each day until the conference I’ll share one article from it-notes.dragas.net about FreeBSD, OpenBSD, NetBSD, DragonFlyBSD, ZFS, PF and more. The dedicated hashtag will be #EuroBSDConAdvent
Let’s start right away with "I Solve Problems" - my EuroBSDCon 2024 (and #BSDCan 2025) talk about migrating from Linux to BSDs:
https://it-notes.dragas.net/2024/10/03/i-solve-problems-eurobsdcon/
If you’re coming to Zagreb, reply to this post - it would be nice to meet up with fellow BSD users!

Confidential Computing with OpenBSD -- The Next Step by Hans-Jörg Höxer
Confidential computing is a family of techniques to enhance security and confidentiality for data in use. One technical approach is strong isolation for virtual machines.
AMDs Secure Encrypted Virtualization (SEV) offers several feature sets for isolation of guest virtual machines from an non-trusted host hypervisor and operating system. These feature sets include memory encryption, encryption of guest state including CPU registers and an attestation framework.
With OpenBSD 7.6 released in October 2024 we are now able to use the memory encryption features of AMD SEV to run OpenBSD as both
a confidential guest VM and
as a hypervisor providing a confidential execution environment.
Now, thanks to memory encryption the hypervisor is not able to peek into a guests memory and is not able to retrieve sensitive information. However, the state of the CPU registers used by the guest is still visible to the hypervisor.
Therefore, we implemented support of AMDs "Secure Encrypted Virtualization with State Encryption" (SEV-ES) for OpenBSD guests and hypervisor. With SEV-ES all CPU guest state is encrypted and hidden from the hypervisor.
In this talk we will explain the fundamentals of SEV and SEV-ES. Then we explore the challenges imposed by SEV-ES for both guest and hypervisor. Finally we will take a closer look into selected implementation details.
Hans-Jörg Höxer is employed at genua, a German firewall manufacturer, who is using OpenBSD as a secure and stable base for its products.

An embedded "dev kit" for EndBASIC with NetBSD
by Julio Merino
In this talk, I'd like to present how I took EndBASIC and built a NetBSD-based embedded device that boots into this interpreter in just a few seconds.
EndBASIC is a side project of mine that implements a retro-looking BASIC environment. Up until now, this featured a web interface and a desktop interface -- but I wanted to offer a prebuilt image for the Raspberry Pi that booted almost-immediately and was resilient to reboots. You know, like the computers of the 1980s, because I believe such a simplified environment can help with learning the basics of programming.
For this project, I picked NetBSD as the core due to its great cross-building features and then implemented new backends for EndBASIC to leverage NetBSD's native features. In particular, I wrote a driver for NetBSD's wscons framebuffer to have graphics output without having to even start X11.
The result is that I can build a full disk image from my Linux development box for NetBSD, write it to an SD card, and have a Pi boot straight into EndBASIC in about 5 seconds.
What's more: the whole of EndBASIC is written in Rust, and cross-compiling it from Linux x86_64 to NetBSD aarch6 is challenging. I bridged this gap with qemu and automated the whole thing so that I can build images end-to-end without even looking. Having proper cross-build support would be desirable, and I'll cover that.
I can also cover the contributions that this project led to upstream NetBSD, which actually made me recover my account and come back to contributing.
I'm actively working on this project and, from now through June, things may change significantly and I might have new things to talk about and demonstrate. For example, I want to integrate with NetBSD's WiFi stack, or SPI to leverage a tiny LCD. But for now, that's what I can offer for this talk!
