Subject: [PATCH] VIA and SiS AGP chipsets are x86-only


There's no point in troubling the Alpha, IA-64, PowerPC and PARISC
people with SiS and VIA options. Andrew thinks it helps find bugs,
but there's no evidence of that.

I don't know about SiS, but this is certainly *not* true for Via. There
are some PowerPC and, IIRC, Alpha motherboards that have Via chipsets.
My config-fu isn't quite what it should be, so this may be a dumb
question. Does the "& X86" requirement exclude x86-64?

No, X86 includes both X86_32 and X86_64.

Yes, but they don't have VIA *AGP*. At least, that's what I've been
told by people who know those architectures.

Yeah, I don't know of any VIA AGP chipset used on ppc...

Pegasos has a VIA southbridge but no AGP.

VIA south gets used by a lot of the systems but the VIA North bridges
I've got docs for cover only x86 variants, although one of the older ones
implies it has both K7 and Alpha support (just as the AMD chipset does)

Personally I'd rather know when I broke stuff by getting everything
to compile that sanely compiles. Operating the ".config" file is not
complex after all.

VIA chips (even southbridges) have never been used on Alpha.

I double checked, and you're right. Please ignore my noise.
