There will be many more stories about Chinese "Open Source" CPUs, because the USA has declared a strategy for this decade to control and limit the flow of advanced semiconductor tech to China. China would love to have bright minds from the West contribute to "Chinese Open Source" CPUs. Western contributors will find that these "Open Source" designs can only be economically fabricated in China, though, creating dependence on China.

It is a good strategy that has worked historically. Sugarcoat your real goal with some humanitarian bs and then have the best talent of the world working for you.

Chinese companies have focused on RISC-V as an alternative to ARM since the export controls. The thing with their chips is that SDK support is somewhat lacking? This is my conclusion after working with the extremely popular ESP devices.

Are you talking about the riscv esp32-3c SDK? Because I think the Espressif SDK has really matured over time for their other cores.

The documentation is far from top notch. Compare it with Zephyr OS documentation and you'll see quite a difference.
