Φαίνεται πως υπάρχει μομέντουμ πίσω από το RISC-V, αν βέβαια δεν το σαμποτάρουν οι αμερικάνοι.

Εχει οντως παρει μπρος η φαση και οι βελτιωσεις μοντελων πανω σε αυτο το προτυπο γινονται με αλματωδεις ρυθμους. Δε νομιζω να ρισκαρουν οι αμερικανοι να απομονωθουν απο τον υπολοιπο κοσμο, ειδικα κινησεις σαν και τη παραπανω δειχνουν πως εχουν ανοιξει επιτελους οι πυλες του μονοπωλιου της τεχνολογιας απο αυτους

Lichee Console 4A - RISC-V mini laptop : Review, benchmarks and early issues : Svarichevsky Mikhail

Conclusion​

My overall experience with Lichee Console is positive and I like it.

It should be noted that at the moment it is more of a product for tinkering and not something that you can immediately use as-is for work with no changes.

Substantial improvement will be required on software to fully utilize hardware capabilities (but this often happens with Linux on mobile platforms). Hardware has some flaws, they are unpleasant but not fatal (microsd stability at high speed, high idle power consumption). I am concerned about battery safety, and hopefully this is something that Sipeed can improve.

12nm TH1520 SoC offer competetive dynamic power consumption and sufficient performance, but lacks in IO (for desktop) which forced Sipeed to add additional interface ICs which happened to consume too much static power.

I hope that current rapid pace of RISC-V infrastructure development will continue and in the nearest years we'll see more RISC-V SoC's, this time with at least few lines of PCI-E - and we'll get even more exciting Linux-capable RISC-V devices.

Making an RISC-V OS (Part 1): Project Setup

Long term goals​

The plan of this series of articles is to make a full blown OS, with filesystems, PCIe support, a good POSIX compatibility...


The OS will only target the virt machine of QEMU, in order to simplify the implementation.Performance won't be a major goal, as I will do everything alone, and as such I will try to keep things simple.


This project is meant to be a way to learn about low-level systems subjects, and in the longer term maybe higher level subjects.Most of the software developed in the project is going to be in Rust, but I will still try to run external programs in other languages (C/C++ utilities for example).

Πολυ καλο προτζεκτακι γραμμενο σε Rust, ειναι βημα βημα work-in-progress και εχει πολυ καλες πληροφοριες!
