I can not find infos about the Vector-extensions ? Is this cpu/board suitable to test the RISC-V Vector extensions ? thx for any insights..

I have one. Yes, I'm currently using it to successfully test vector instructions. A blog post is being written, but may take a week or so. Keep an eye on blog.habets.se, or ping me here on HN in about a week.

  Seems I can't add another reply, nor edit the one I created. But [here's more info about the Orange Pi RV2 and RVV](https://blog.habets.se/2025/03/Exploring-RISC-V-vector-instructions.html https://blog.habets.se/2025/03/Exploring-RISC-V-vector-instr...).

Yeah, they somehow released a SBC without telling us what processor it contains. It seems to be the same one as the BananaPi BPI-F3, see: https://www.reddit.com/r/RISCV/comments/1j6c6xz/orange_pi_rv2_riscv_sbc_powered_by_ky_x1_octacore/ https://www.reddit.com/r/RISCV/comments/1j6c6xz/orange_pi_rv...

  As per the article: "The biggest difference between the two boars is that the Orange Pi RV has a 1.5 GHz StarFive JH7110 quad-core processor, while the new Orange Pi RV2 has a an octa-core Ky X1 chip with a 2 TOPS AI accelerator." The link you posted goes to the exact same board as in the article.

    It's not about the article, but the comment from u/12101111: > It's a cheaper Spacemit K1. > The CPU spec from dtb: > compatible = "ky,x60", "riscv"; model = "Ky(R) X60"; riscv,isa = "rv64imafdcv"; riscv,isa-extensions = "i", "m", "a", "f", "d", "c", "v", "zicbom", "zicboz", "zicntr", "zicond", "zicsr", "zifencei", "zihintpause", "zihpm", "zfh", "zfhmin", "zba", "zbb", "zbc", "zbs", "zkt", "zvfh", "zvfhmin", "zvkt", "sscofpmf", "sstc", "svinval", "svnapot", "svpbmt"; > It also have a ARM China Linlon v5 VPU and Imagination IMG GPU.

      From memory, the SpacemiT K1 doesn't support extensions like Zvkt? EDIT: okay, looks like the official documentation lists it, but many places I looked didn't. Maybe it wasn't being detected in cpuinfo?

It seems likely to be the same as this chip, so yes. https://docs.banana-pi.org/en/BPI-F3/SpacemiT_K1 https://docs.banana-pi.org/en/BPI-F3/SpacemiT_K1

It has a JH7110 onboard. From what I can tell, all of the vector processing is in dedicated hardware subsystems, not individual vector instructions. We're still very early in the RISC V ecosystem, so most of the processors in production pre-date current standardizations, which requires applications to target specific silicon. To add insult to injury, those individual processors are relatively new, so the dedicated image processing and vector/tensor hardware doesn't have much support yet.

  This is not JH7110 based.
