XiangShan VS redroid-doc

Link to the open-source processor implementation: https://github.com/OpenXiangShan/XiangShan/tree/nanhu

You can download and simulate it on regular hardware.

I ran a few micro benchmarks it XiangShanV2 (Nanhu), the one in the laptop, and XiangShanV3 the next generation of their implementation:

    integer micro benchmark from the XiangShan repo:

Are you calling for the government to pick a winner? The Chinese word for this fierce if at times chaotic competition is "juan". It worked for them in EV and PV. The outcome remains to be seen in chips and commercial space launches. But even their mostly (ex-)students-run open source Xiangshan RiscV project https://github.com/OpenXiangShan/XiangShan shows a remarkable level of sophistication.

> Certainly no RISC-V implementations that are in the hands of customers right now do any fusion and it doesn't seem to hurt their ability to match or exceed the performance of similar Arm cores (A55, A72).

You can play around with OpenXianShan though, they have a few fusion targets: https://github.com/OpenXiangShan/XiangShan/blob/master/src/m...

Most of the targets require the same destination, so it won't be able to fuse current codegen. I suppose there is still some time before compilers need to be ready, but it's not that much.

I hope so, btw t-head seems to be still be trying to upstream XTheadVector: https://gcc.gnu.org/pipermail/gcc-patches/2024-January/64278...

This is the most advanced open source risc-v implementation I'm awair of: https://github.com/OpenXiangShan/XiangShan

Maybe implement a big feature for a open source design? like vroom or xiangshan.

I did know about XiangShan, but not Aolai. Is it a Linux distribution?

If you are interested in high performance look into vroom , c910 and xianghan, maybe you could adopt one of them.

I've been trying to install ReDroid following this guide (replacing docker with podman) but the container gives only the following output:

Hmm, again

The building insturction is here. You have to manually build a ReDroid image with Gapps...It took me 7 hours and thank god now Gapps is working.

I would say redroid is better. docker-android seems to be something geared towards developers.

Might want to check out ReDroid

Any Linux distro + Android in a container solution(Example)(recommended)

don't test me in vice versa

And even better Android is a Linux too, and can run inside containers(*like separate operating systems from the same families sharing the same kernel) in every Linux distros you could find, for example Chrome OS' Android container, Anbox, Waydroid, Redroid benefits from that.

4- Android is a Linux distribution, basically same kernel can run both GNU userland of Chrome OS and Bionic Libc/ART userland of Android, without needing much resources, this is called containerization. It is nothing new, any regular GNU/Linux distro can run Android containers, Redroid for example.
