openc910 VS clash

> I'm pretty sure that SiFive isn't allowed to sell their RISC-V core designs to any Chinese company already.

The JH7110 SoC from the Chinese firm Starfive uses SiFive's U74 core. Eswin, also Chinese uses SiFive's P550 core in their upcoming EIC7700 SoC.

> All Chinese RISC-V core designs have been proprietary designs thus far.

There is the OpenC910 [1] and OpenXiangShan [2].

Note that the C910 CPU cores used in this chip are in fact open source:

(C920 is just C910 plus RVV draft 0.7.1 vector unit which pretty much no software uses anyway, sadly)

The Milk-V Pioneer uses a C910 CPU, which has been open sourced by t-head: https://github.com/T-head-Semi/openc910

More precisely, a Chinese university assembled a rack containing 48 [1] commercially available SBCs [2], each with a Chinese-designed and made SG2042 SoC with 64 C910 CPU cores. The C910 was designed in China in 2018/19 and open-sourced in October 2021, on Microsoft's github site.

The SG2042 is the most powerful RISC-V SoC available today.

In which direction is the technology transfer going?

For "coming down the pipeline" they're essentially free.

Today, the c910 is an Apache 2, hardware proven out of order core on GitHub here https://github.com/T-head-Semi/openc910 a little slower than an RPi3's core.

Here is the source code* for the CPU:

https://github.com/T-head-Semi/openc910

* AFAIK they didn't opensource the pre ratification vector extension implementation they ship with the taped out chip.

The source RTL for the roughly Arm A72-equivalent cores used in this were open-sourced several years ago.

The same cores are used in the 64 core SG2042 workstation/server SoC.

It's a shame, because it was the best design from ARM; they're now focusing on Cortex-A7x and Cortex-X, which aren't anywhere as power efficient[0].

Meanwhile, their revised Cortex-A57 has been surpassed in performance/power/area by several RISC-V microarchitectures, such as SiFive's U74[1], used in the VisionFive2 and Star64, or even the open source XuanTie C910[2][3].

being one of the developers of the Clash core (https://github.com/Dreamacro/clash) and its closed-source (free of charge) premium version (clash-premium), i'm really heartbroken seeing this - everything is tearing down.

even without the context of being in China or Iran, Clash is still an awesome piece of software that can be used everywhere, with proper understanding of computer networking.

i ain't sure if both Dreamacro and Fndroid are physically safe now, but i'm sure they are both physically in mainland China.

Now, I have been meaning to set up a Clash proxy to set my whole network to use ProtonVPN (via Wireguard) and possibly add other nicities to it such as Tor and I2P access, simply because it supports it and ... well, I can. :)

I feel you man. But check this out. It's a proxy server provider that i used before, they provide two Taiwan proxy servers for free and set up all the protocols for you. It's so much easier than setting up things on your own server by yourself. It's pretty stable as my experience. And you need a proxy client to use it, I recommend clash. Basically you just install clash and download profiles on the provider's website. Then you run clash -f path_to_your_profile, and set environment variable http_proxy and https_proxy to the port that clash is listening to. Usually it's 7890, so you set environment variables http_proxy=http://127.0.0.1:7890 and https_proxy=http://127.0.0.1:7890 for example and all done. It won't take too much time to set it up, but you need to do some translation work to that website, it's Chinese because who else in this world need to use this thing anyway.

Hi, unlike X-ray panel which has a very straightforward procedure to set it up and running on VPS, there is absolutely no guide on how to set up clash, I'm kindly asking is anyone here is knowledgeable about running clash step by step.

So, for reference if someone comes across this and doesnt know which Clash we mean: https://github.com/Dreamacro/clash

can also consider the Clash
