CPU minimum requirements?

What is the minimum supported CPU on Arch32? Will it work on a Pentium MMX?

Re: CPU minimum requirements?

The current repositories require a Pentium Pro, i686. Some chips reporting as i585 (like the Geode LX on an Alix 1E) also work.
The CMOV opcode must be available.

Have a look at /proc/cpuinfo. Minimal requirements to boot are MMX and CMOV.

Some packages may require SSE and SSE2.

That's something we would like to sort out by separating the repositories in the future as follows:
- 486: no MMX, SSE, SSE2
- i686: MMX only
- pentium4: with MMX,  SSE and/or SSE2 optimizations

Re: CPU minimum requirements?

That's good to know you are planning to support older x86 processors. I might suggest you have a category for Athlon XP which has SSE, but not SSE2.

Re: CPU minimum requirements?

I'm not sure about having a separate "architecture" for Athlon XP.
There are far too many features, which you can have / not have, thus creating quite a lot of repositories.
The question is, if there is such a big performance gain in having sse vs. not having it and if there are any packages which need sse (but not sse2) - which would be available for you then, but not if a separate architecture was not introduced.
