Wanting to decommisson any pre-haswell based computers I currently run for servers I purchased one with a comet lake-s cpu. As I am not made of money I cheaped it out and got one with a pentium gold g6505.

  x86-64-v2 (supported, searched)

oops. I should have done more homework earlier where I would have discovered that the necessary instruction set extensions to qualify as x86-64-v3 are not included on that chip. Cancel using c10s. Good thing there is almalinux 10. I also have to reevaluate fedora server.

I ran F41 Server on a Phenom II, but I recently switched that out for something Intel.

ld.so --help is pretty cool! I’ll have to check that other Intel CPU later, but a i5-8400H looks ok:

Is this something that can be switched on Fedora now (assuming .2 is a v level and could be 3)?

This program interpreter self-identifies as: /lib64/ld-linux-x86-64.so.2

In fact, Fedora 41 can even run on x86-64-v1. :eyes:
