Subject: What processor features does Guix support on i686?
Date: Sun, 2 May 2021 00:59:16 -0400 [thread overview]
Message-ID: <YI4xpDGiZdbUYkfF@jasmine.lan> (raw)
I noticed that Linux 5.12 has a new config option regarding "Processor
family". The default choice, Pentium-Pro (M686), is highlighted in this

I know that, in the past, we have been careful to not require certain
processor features on i686, such as SSE [0].
I would appreciate some guidance, both about this kernel configuration
option, and what we have historically considered to be the "minimum
requirements" for i686 hardware. I will put that information the manual
so that it doesn't get lost.
