Last day of EU is on, come and stop by the booth! We still have a few plushies left, if you beat our quiz 😉
And we are also showcasing a educational emulator on the MilkV Pioneer running Tumbleweed.
The emulator has been made by @ppisa and his students from the Faculty of Electrical Engineering, ČVUT and is on github: https://github.com/cvut/qtrvsim

The first day of #OpenSourceSummit on the #SUSE booth together with @Defolos and other #SUSE people is over. The presentation of the new #QtRvSim release as well of simple fluid dynamics demo on #MILKV Pioneer #RISCV hardware with #openSUSE GNU/Linux system run smoothly. As well as, @remus32 prepared motor control demo with visualization on #MILKV implemented in #RUST and #CANbus connected MCU board running #Zephyr. The CTU CAN FD IP cores have realized CAN FD communication. Thanks again to #SUSE for invitation of #CVUT #CVUTFEE at their booth at this conference.

We're at EU until Friday, showing of the Milk-V pioneer, running Tumbleweed. Come over and take a look!
We have a RISC-V emulator too, that emulates RISC-V on RISC-V thanks to @ppisa 🥳

Since Friday, BengalOS gained support for DisplayPort on SHIFT 6MQ.

This is a new addition to the recently added USB-C role switching (OTG).

Kernel support included from the `sdm845-next-20260820-15` tag, if you want to integrate it into your project!

Goodbye #LinuxDays2026, warm welcome at #OpenSourceSummit in #Prague. The #openSUSE Tumbleweed installation on #MILKV Pioneer 64-core #RISCV system, presented at #LinuxDays running our #QtRvSim educational simulator (Sv32/Sv39 visual emulation on Sv39), #pysmiCoder, and CTU CAN FD-based #CANBUS controller on CycloneIV PCIe board, will be available to play with on the @opensuse booth at #OpenSourceSummit from this Wednesday till Friday. The graphical #Rust application for control and visualization of a CAN FD-connected motor controller running on the MCU in #Zephyr has been implemented @remus32. I have bootstrapped (through Canadian cross from my #Debian) git version #FreePascal and built the #Lazarus libraries, which allowed me to build our Open Chromatography Station CHROMuLAN software. Even though this child #CHROMuLAN chronically starves for more love and maintenance time, it is being actively used with our HPLC and amino acid analyzer systems for decades. It is one of the few open systems available for chromatogram evaluation, even for other instruments in general; see references at Scholar for its use in application and primary research. But compared to these achievements, the #SuperTUX and #SuperTuxKart have been the most appreciated applications on this 64-core RISCV box by #LinuxDays children visitors.

Great stuff you get to see at : tumbleweed running on a board, the MilkV thanks to the work by @ppisa and colleagues 🥳

Come to tomorrow to see it live!

#QtRvSim 0.9.9 release adds Sv32 and Sv39 #RISCV standard MMU, S and U modes, PC position in source code visualization, and direct fetch and submission into the evaluation site. Online version at #CVUT central computer architecture education site https://comparch.edu.cvut.cz/ is updated as well as GitHub release page, where you can find a little more detailed changelog with contributors’ attributions. The related lectures sources are available at https://github.com/cvut/comparch-slides;

We send our big thanks to SUSE.com, who conceived and support the openSUSE Build Service (https://build.opensuse.org/), which allowed us to start QtMips and then QtRvSim packaging for a broad range of Linux distributions in the past, and motivates us to prepare it for openSUSE as well.

We will present advances in QtRvSim and the RVapo VHDL equivalent with a new GDB interface at https://www.linuxdays.cz/2026/ on Sunday, October 4. We will have the Open Technologies Research Education and Exchange Services booth there with our whole hardware ZOO and #QtRvSim running on Milk-V Pioneer 64-core RISC-V system with an openSUSE Tumbleweed installation. Thanks to #SUSE’s sponsorship, we will continue demos at the #openSUSE prepared booth, focused on cooperation with #CVUT, #CVUTFEL, and other academic institutions at Open Source Summit Europe in Prague from October 7 to October 9.

Introduced QtRvSim MMU, which allows running MIT PDOS XV6 (slowly and slightly modified for QtRvSim).

We will present other RISC-V hardware, as well as our #CANbus projects, including the CTU CAN FD IP core on PCIe card in #MilkV Pioneer, industrial control projects, and educational projects, e.g., pysimCoder.

Thanks to @remus32 for helping with #MilkV Pioneer bringup as to Han Gao RevySR. We have used his RevyOS to bringup system and boot it with his #Debian derivative kernel and EFI boot. We have switched to Linux his 7.3.0-rc4+ #Linux kernel built on openSUSE. The mainline #Grub EFI has been used as the second stage loader.

I will attend the ESA Industry Space Days next week. I would be happy to meet and discuss our #RTEMS, #Linux, #NuttX, communication, #canbus, #SpaceWire, IP cores related work. Some examples

I arrive to Noordwijk around the lunch time on Tuesday September 15 and stay there to about 2 PM on Friday so there is lot of options to meet.

Xiaomi Mi 8 (codename dipper) landed on my desk today.

Inserted SIM card, logged in into Xiaomi service a voila, unlocked.

I'll try to introduce some basic support, but without active community don't expect comparable experience to OnePlus 6 or Xiaomi Poco F1.

Seriously, we're happy that people use our work, but we need active devs.

We working on phones which aren't "cool" today. Phones based on Snapdragon 845 are phones which people actually daily-drive.

The #SpaceWire ( #satellite oriented wired communication standard) #OpenSource #GNU/ #Linux software support (C library, CLI, Python) for Remote Memory Access Protocol ( #RMAP ) initiator and target realized by STAR-Dundee RMAP IP Cores integrated into custom variant of TEDIA PCD-8006 PCIe expansion card developed by Kyaw Htet Lin at #CVUT #CVUTFEL and his related thesis have been published.

The project page https://gitlab.fel.cvut.cz/otrees/spacewire/spw-pcie-tedia, Wiki, Thesis PDF, Presentation PDF and complete record with review reports https://dspace.cvut.cz/entities/publication/490357d1-8609-414e-91ad-87d4cc0e9b7e.

Longer term plan is to continue with support of more SpW IP cores, #RTEMS and #Zynq and #BeagleV/ #BeagleVFire with potential to be used even for space qualified #PolarFire #SoC.

Thanks to the great work done by @wrenix, @valpackett, and many others (certainly not me), I've finally gotten calls working on my Fairphone 5.

While there's some kinks left to be ironed out, call quality is excellent out of the box (certainly better than my PinePhone (Pro)).

I've pushed a `linux-sc7280-calls` kernel to my arch repo for anyone who wants to try it. The following PR discussion should help set it all up:

I wanted the blue checkmark on LinkedIn. The one that says “this person is real.” In a sea of fake recruiters, bot accounts, and AI-generated headshots, it seemed like a smart thing to do.

So I tapped “verify.” I scanned my passport. I took a selfie. Three minutes later — done. Badge acquired. I felt a tiny dopamine hit of legitimacy.

Then I did what apparently nobody does. I went and read the privacy policy and terms of service.

Not LinkedIn’s. The other company’s.

UK, welcome back to Erasmus+ 🇪🇺🇬🇧

The EU and the United Kingdom sealed the deal to bring the UK back into Erasmus+ from 2027.

We are rebuilding opportunities for the next generation to study, work and grow together, giving people the chance to connect across borders once again.

It will also help create and deepen partnerships between our academic institutions.

Together again through learning, exchange and connection 🤝
