🌖 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. 🚀

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!

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

Over 250 billion Arm chips have shipped since the first #ARM1 processor launched 40 years ago
ARM1 #CPU ended up being a pioneering #RISC chip, featuring just 6,000 gates, while modern Arm processors feature more than 100 million.
Arm admits that the signature quality of its chips – their energy efficiency – was driven out of frugality they couldn't afford ceramic chip packaging so had to be very strict about efficiency, so plastic packaging would be acceptable.

Angelina Jolie Was Right About Computers | WIRED

｢ China’s top scientists have heralded RISC-V as a path to silicon independence. India just used RISC-V to make its first homemade microprocessor. Name a country; it’s probably experimenting with RISC-V. Brazil sent a record 25 delegates to the RISC-V summit ｣

Atari Jaguar news: This year, there is another JagJam and I'm hoping to see some great, creative new titles for the Jaguar again. The deadline for submissions is October, 31st, which gives devs half a year to make something. So if you are looking for a programming challenge or want to support the jam by spreading the word, please feel free to do so! Cheers!
