RISC-V is a free and open-source instruction set architecture (ISA) for developing custom processors. It is an alternative to proprietary ISAs like ARM and x86, allowing anyone to design, manufacture, and sell RISC-V chips without needing expensive licensing. RISC-V is based on the principles of Reduced Instruction Set Computing (RISC), and has gained popularity due to its open nature and flexibility.

🌖 Rocky Linux 10 正式支援 RISC-V！
➤ 擴展架構支援，擁抱開放硬體
✤ https://rockylinux.org/news/rockylinux-support-for-riscv
Rocky Linux 宣佈其即將推出的 Rocky Linux 10 版本將正式支援 RISC-V 架構，這得益於 Fedora RISC-V 社羣和 Rocky 的 AltArch SIG 的努力。此版本將提供 riscv64gc 建置，支援 StarFive VisionFive 2、QEMU 和 SiFive HiFive Premier P550 等平臺。儘管 RISC-V 被視為替代架構，但其建置失敗不會阻止其他架構的發布，確保套件更新不會因 RISC-V 版本而延遲。
+ 太棒了！RISC-V 的支援意味著更多選擇，對於想要嘗試新硬體的用戶來說是個好消息。
+ 很高興看到 Rocky Linux 積極擁抱新的技術，這表明了他們對開源社羣的承諾。

🌖 GitHub - IBM/ACE-RISCV：安全機密執行環境
➤ RISC-V 系統的安全基石
✤ https://github.com/IBM/ACE-RISCV
IBM 的 ACE-RISCV 專案是一個開源的機密運算框架，專為嵌入式 RISC-V 系統設計，並著重於形式化驗證和可審計的韌體。它實現了基於虛擬機（VM）的受信任執行環境（TEE），支持本地證明和後量子密碼學，旨在提供高安全性的運算環境。
+ 這真是一個令人興奮的專案！形式化驗證對於確保系統安全至關重要，希望它能推動 RISC-V 在安全應用領域的發展。
+ 對於嵌入式系統來說，本地證明功能非常實用，尤其是在無法連接網路的環境中。期待看到更多關於 ACE-RISCV 的應用案例。

🌖 實作基於RISC-V H擴展的虛擬機器監控程式
➤ 從零打造RISC-V虛擬化架構的技術實錄
✤ https://seiya.me/blog/riscv-hypervisor
開發者記錄在Starina作業系統實作RISC-V H擴展虛擬化的完整歷程，從基礎架構搭建到成功運行Linux核心，詳解技術挑戰與解決方案。
+ 「RISC-V的CSR設計確實比x86簡潔，但htval位移位問題實在太容易踩雷！」
+ 「作者選擇virtio-fs而非傳統blk裝置的決策邏輯值得深入探討，期待後續實作細節公開。」
##RISC-V #虛擬化技術

🎉 Ah, the classic tale of an overenthusiastic developer who decided that implementing a #RISC-V #hypervisor would be a fun weekend project. 🤦‍♂️ Apparently, the thrill of virtual machines and obscure CPU extensions is just too irresistible. Spoiler: it's just like Intel VTx but with more acronyms and fewer people who care. 🚀

Implementing a RISC-V Hypervisor

Have a couple more openings on my team for folks if you want to come play:

First up is a Rust developer, mostly working on things like Luwen and working on moving some of our python based tools down to rust based tools. Lots of things coming, and all down in the systems stack.

https://job-boards.greenhouse.io/tenstorrent/jobs/4736078007

Second up is someone to come work on the OSPO side of things, day to day chasing stuff down on that front, getting out ahead, policy stuff, and some side scripting to help make things in a few directions better.

https://job-boards.greenhouse.io/tenstorrent/jobs/4736080007

Solid team, lots of interesting problems, and we are working in the open on open source tooling for things here.

Worth taking a look!

#RISC-V #AI PC Delivers 50 TOPS, Runs #Ubuntu 24.04, fits the @framework laptop case 💪 Almost all configurations already sold-out !

Hackers (1995) called it: Angelina Jolie's character knew RISC architecture would change everything. 30 years on, that prophecy is more potent than ever, silently reshaping tech. Let's talk RISC. #RISC #TechProphecy #FutureTech

silly question:

how many instructions and registers would a minimal RISC be?

load, store, move, add, sub, nop, jump, beq, blt, and, or, xor, not, shift left, shift right, mul, div, rem, min, max, call, ret, sys, int?

general purpose, return addr, stack pointer, func args(x?), saved registers(x?),

maaaybe a time register and identity register, an interrupt masks register that can only be written by a privileged process... so a ring register?

DeepComputing Unveil RISC-V AI PC Running Ubuntu 24.04

Ubuntu is one of the leading Linux distributions for RISC-V hardware thanks to Canonical’s strategic partnerships with companies like DeepComputing – who just announced their powerful new RISC-V AI PC running Ubuntu 24.04 LTS. The DC-ROMA RISC-V AI PC is built around the new company’s new RISC-V Mainboard II, designed for use in the Framework 13″ or 14.2″ laptops. Owning a Framework laptop is not a requirement since a nifty enclosure allows the mainboard to be used like a regular PC. The DC-ROMA RISC-V AI PC—apologies for the caps, its how it’s stylised—uses ESWIN’s advanced RISC-V AI SoC EIC7702X—sorry for even more :sys_more_orange:

Pricing and availability are still under wraps. Are you excited about this RISC-V-powered AI module? Let’s discuss your thoughts! 👇 #BananaPi #RISC-V #AIComputing

I wonder how DEC Alpha compares to RISC-V, given the age gap. #risc
