SPAM: Re: Upstream Support for LoongArch

[Kaiyang Wu <wukaiyang2003@gmail.com>]

Hi Thomas,

We are glad to see your interest in the architecture.

While we currently do not have any European vendors, we are able to 
supply Loongson hardware in reasonably efficient manner, see:

https://loongfans.cn/en/intro#i-m-sold-where-can-i-buy-one

But yes, we are indeed working on supporting more overseas vendors for 
LoongArch hardware. In the mean time, We will continuously maintain the 
unofficial port and align it to the upstream maintenance guidelines and 
idioms. Thank you for the feedback!

Best,
Kaiyang Wu

>> LoongArch is a new RISC ISA developed by Loongson Technology. The Loongson 3 family supports virtualization via the LVZ extension, and while the Loongson 2 family of SoCs do not support virtualization, they are capable of running containerized applications via LXC. The performance of the latest mainstream server processor, Loongson 3C6000/S, is about equivalent to an AMD Ryzen 7 5700 and, the latest Loongson 2 SoC, 2K3000, is about equivalent to an Intel N95. This means that Loongson's mainstream processors are capable of hosting Proxmox VE instances.

>> There is an existing unofficial port of Proxmox VE 9.0 to LoongArch maintained by Lierfang (https://github.com/jiangcuo/pxvirt). While we recognize their effort on maintaining the port, the repository has not been actively maintained for 8 months. We do not plan on using their patchset and will maintain our own in order to align them for upstreaming.

>> We would like to seek chances to support LoongArch officially by Proxmox in the future. Loongson Hobbyists Community (https://loongfans.cn/en/) will provide long term support for the LoongArch port. If needed, we will be able to supply LoongArch devices for testing. To support the upstream work, we would like to know about the current workflow for managing patches, maintenance, and testing process. We are happy to answer any of your questions or comments.
