Phoronix: LoongArch Wires Up Real-Time Kernel Support & Lazy Preemption

Merged for the Linux 6.12 kernel was the long-awaited real-time "PREEMPT_RT" kernel support and allowing it to be enabled across x86/x86_64, ARM64, and RISC-V CPU architectures. With the Linux 6.13 kernel, LoongArch is joining the RT party...

This is pretty silly architecture to begin with. It's essentially unobtainium outside China, largely to my understanding for political reasons.

Not really. National security sort of demands that market makers (aka US, China, Russia and EU) each have their own chip-sets.

At this point, since two years ago all the x86_64 instruction sets (the original one) are copyright free, they should ditch the emulation part and fully reverse engineer the x86_64 instructions. Then they wouldn't have these non-optimal compilations (or even compilation failure).

Chips are overtaking everything, so if a market maker was cut-off, they would become completely vulnerable.

Remember when there was a chip shortage so you couldn't find a car? Like that, but way deadlier.

Also, it's unobtainium in China too. It's just for critical systems and educational institutions.

Not true. I can order loongarch machines and motherboards on major e-commerce sites and have them delivered to me tomorrow.
Out side China there is Aliexpress.
