Loongson Continues Working On LoongArch For Linux, But It's Mostly Copying MIPS Code

Of course it is MIPS, as I said when MIPS was EOLd. Loongson are in an awkward position, they clearly have no intention of dropping MIPS architecture, and why should they? However, MIPS is dead (officially). They probably *can't* call it MIPS anymore if they want their CPUs to be sold in other markets.

Quite honestly it strikes me as a somewhat political move "killing" the architecture when China is still has a significant strategic stake in the technology. MIPS isn't fashionable anymore, but it is still viable.

Upstream kernel can't really just let a copy-paste new architecture in the kernel, that would be crazy, but Loongson calling it MIPS obviously has legal issues. Maybe some kind of compromise is needed? Maybe rename the kernel MIPS architecture: "(not) MIPS"?! ;-)

Of course it's a MIPS ripoff. China's tech industry still hasn't risen to the level of inventing from whole cloth anything that can compete with x86/POWER/ARM. They haven't funneled enough stolen IP back to the fatherland to accomplish that yet. 🤡

Flygoat (as jiaxun.yang at flygoat.com) felt tired.
He tried to persuade not to use MIPS heritage.

Phoronix: Loongson Continues Working On LoongArch For Linux, But It's Mostly Copying MIPS Code

Loongson this summer rolled out their 3A5000 processors built on their own "LoongArch" ISA. While the company continues claiming that LoongArch is "not MIPS", the Linux kernel code they continue proposing for the mainline Linux kernel points to it being a close facsimile to MIPS...
