RISC-V With Linux 6.18 Brings Support For MIPS Vendor Extensions / Phoronix
｢ Back during the Linux 6.17 merge window the RISC-V changes were rejected as "garbage" for being submitted too late in the merge window and with some code choices that upset Linus Torvalds. With lessons learned, the RISC-V changes for Linux 6.18 were submitted today during the first official day of this new kernel cycle ｣
Want to build secure systems you can actually trust? You need open hardware. See how #open secure elements enable auditability, fast fixes & real innovation in this #oSC25 keynote. #RISCV #openSUSE #tropicsquare https://youtu.be/LK1NwIMHc1g?si=ej8rUmQPjARXVrIl
Our lead relay engineer @alexhaydock has increased our stateless #Tor exit relay deployment to 96! (+1 because of the new #RISCV bare-metal node, +1 other we redeployed due to a silly spelling error). We're stress testing our three AMD Epyc 7402P servers that use #Proxmox.
Each one of the 96 Tor exit nodes are diskless Unified Kernel Images, 56MB in total size, using @alpinelinux's alpine-make-rootfs with an absolutely bare minimum number of packages. We'll be publishing more about our new architecture and configuration soon.
My friend @Needlesscomplexity has posted two articles about RISC-V assembly language techniques to his substack:
https://needlesscomplexity.substack.com/p/efficient-risc-v-range-checking
https://needlesscomplexity.substack.com/p/efficient-sign-extension-on-risc
And a library of useful integer operations:

I did a lot of assembly language programming back when dinosaurs still roamed the earth, and there are still some valid use cases even today. I firmly believe that having a grasp of assembly language also helps one write better HLL code.

Linus Torvalds Rejects RISC-V Changes For Linux 6.17: "Garbage" • Phoronix
｢ Linus Torvalds has used his authority to reject the RISC-V architecture changes for the Linux 6.17 kernel. The RISC-V updates won't land this cycle and will need to try again for v6.18 later in the year ｣
Another hardware-focused project is #RIVET, making a plug-and-play way for #RISCV systems to connect to #ethernet 
https://nlnet.nl/project/RIVET/
These are the small things that go a long way in speeding up #OpenHardware development.
(I don't know if you gathered, but I like using open, customisable, and repairable devices that I can specially tailor to my needs—and I'm excited to see this take more shape in future!)

The RISC-V community is very active in Fedora. Initial support for RISC-V in @centos was started from Fedora and they just want to keep on trucking!
If you want to learn more about how our open OS is meeting their open architecture, check out their Matrix room!

ICYMI: Canonical partners with ESWIN for new RISC-V SBC with support for Ubuntu 24.04 - but it won't be able to run Ubuntu 25.10 or later.

#RISCV is now fast enough to run *Crysis* in an *emulator*?! Wow! How's the frame rate?
Also, I see a lot of complaints in that thread about GPU availability. Wasn't there a project to make a RISC-V GPU?
The long awaited Black Magic Debug V2.0.0 release is finally here! It is a big update with a lot of improvements and newly supported targets. It pairs very well with bmputil, make sure to give it a try! See release notes for more details. Thanks to everyone who contributed!

@ekaitz_zarraga Would be nice to meet in person in sunny Valencia to discover your work around #riscv bootstraping and #guix.

Ubuntu is raising its RISC-V profile requirements to RVA23, requiring vector and hypervisor extensions to be included. Most existing RISC-V SBCs on sale lack them.

I suppose the #Nvidia #Jetson form factor is a kind of standard interface for #systemOnModule #SBC
There's already a #RiscV #SoM called the #MilkV Jupiter that's supposedly compatible with a #NvidiaJetson #carrierBoard, and now the #radxaN150 with an #x86 chip.
I'd be interested in seeing someone try various Jetson boards with the available modules.

In my little world of #RetroComputing, I have stumbled across minor issues in some of the tools that I use.
I've had two cases so far where maintainers very quickly took my suggestion and made it available in their main branch. I've also had one where I haven't heard back from the maintainer, i.e. where I'm going to need to maintain my own fork (for #RiscV compatibility). And that's OK. Beyond being glad that I got help, I'm glad that the original authors allow me also to do the work myself.
