Phoronix: Linux 5.16 KVM To Land RISC-V Hypervisor Support

Coming with the Linux 5.16 kernel cycle will be support for RISC-V virtualization with the Kernel-based Virtual Machine (KVM)...

The RISC-V ISA recently settled on its hypervisor extension and its spec is now considered frozen.

Wow that's awesome! I seem to remember it being a huge pain point with RISC-V and people complained that after so many years it wasn't stable.

Yeah, but I don't know if there are any mistakes in in the RISC-V ISA and if maybe ARMv8 (and ARMv9) are better than RISC-V. I've heard some rumors about the RISC-V ISA not being all that good. Everyone seem to agree that ARMv8 is great though.

Can you share links to this discussions?
I don't know much of ISA, but want to read some arguments (positive and negative) on RISC-V.

This is a post by an ex-ARM engineer. The post is quite technical.

Ahh, this is it! I made some similar comments here that I thought I read some complaints about RISC-V, but couldn't remember where. This is what I read. That said, all this is over my understanding (especially since I skimmed it), but yeah someone took issue. I cannot judge good or bad, just know I read this.
