[ERROR]: print_ascii_riscv: Unable to find the extension to print (VisionFive 2 / JH7110)

[JamiKettunen]

I see the titled error when running ./cpufetch after build on my VisionFive 2 (JH7110 SoC) with https://chimera-linux.org/:

The command still appears to mostly work and exists with code 0, and it doesn't appear to be present if I try ./cpufetch --logo-short instead:

                                 SoC:                 StarFive VisionFive 2

    ########   ########           - (H) Hypervisor

My theory is it tries to address the hypervisor core in the --logo-long mode as it also prints Supervisor-level Instructions under extensions before erroring; my kernel is v6.5 from https://github.com/esmil/linux/tree/jh7110/ with mainline U-Boot & OpenSBI as well

Hello, can you please download and compile the last fix in bugfix4 branch and report the output of ./cpufetch -v?

The fix appears to work, did you have something more in mind to do with the multi-letter extensions still?

[Dr-Noob]

Hello, I have added a few more patches and now it should work properly. Can you please confirm in your end?

[JamiKettunen]

Looks about right

LGTM. I'll merge this into main, thanks for reporting the issue!
