those machines would not be able to run a recent Fedora due all the
bloat introduced over the years - try a system update with 512 MB and
shake your hands with the OOM-killer
I have a computer without SSE3. It runs Fedora just fine. I initially had 1
GiB of RAM in it, I upgraded it to 3 GiB.
Fedora incompatible?
many software including the kernel has binary code for AVX and even AVX2
and is using CPU runtime detection - using SSE3 instructions in a
software is not bound to compiler flags and when a upstream developer
don't care about 11 year old hardware you have to suck taht downstrem
What he means is that Fedora policies DO NOT allow REQUIRING those
instruction sets. Runtime detection is of course fine.
The problem we are having now is upstream projects that do not support ANY
kind of fallback, not even at compile time. (Those are also inherently non-
portable because they don't work on any other CPU architecture.) Chromium/V8
is another such problem program.
