Chimera Linux在获得必要的硬件后,撤销了放弃RISC-V支持的决定。一些人认为这意义不大,因为与x86和ARM相比,公开可用的RISC-V硬件有限;另一些人则指出,随着Framework RISC-V主板和DC-ROMA笔记本电脑等产品的出现,RISC-V硬件的可用性正在增长。 然而,现有的RISC-V硬件,例如基于JH7110的开发板,速度慢,与树莓派3相当,因此不太适合用作构建机器。尽管性能有限,一些人认为公众无法获得RISC-V硬件的说法是不准确的,他们列举了Milk-V Jupiter等现成的选择。维持支持的决定,虽然对小众用户群的影响有限,但也符合推动处理器架构多样化和减少对既有技术的依赖这一更广泛的趋势。

Chimera Linux NOT dropping RISC-V support after all (chimera-linux.org)

They wanted to drop support because they didn't have the hardware. Now that they have access to the hardware and not dropping support, I am not sure if it matters much.

The public doesn't have access to RISC-V hardware and it won't have access anytime soon.

The problem to be solved seems availability of the hardware, not support from a small Linux distribution. It's not like we can go to Hetzner and rent a RISC-V server or go to AWS and provision a RISC-V VM.

And the availability will only improve if there is enough demand from the market to build such hardware. The EU and China wanting to be less dependant on US tech might help here.

Of course, RISC-V hardware should be on par on perf/price with x86 and ARM to tempt someone to switch.



Whilst not exactly easy to come across quite yet, there are some signs of growing public availability for RISC-V:

In the original post about dropping RISC-V support chimera Linux mentions that this existing hardware is too slow realistically use for build machines. They specifically mention the JH7110 which powers the framework board and the spacemit k1/m1 that powers the DC Roma laptop.

So yeah there is hardware available but expect raspberry pi 3 or lower levels of performance.

The fuck are you talking about?

I barely pay attention to this stuff and know this is available and have already seen one in person on a colleague's desk:

Good news for their huge userbase (3 people around the globe)
