#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.
