Re: Re: Any one going to change to sata disks?

The fs kernel's sdata.c hadn't been recognising Silicon Image's and
other VIDs and DIDs recognised by the current cpu kernel's sdata.c
I've just updated source's /sys/src/fs/pc/sdata.c to incorporate the
atapnp() code from the cpu kernel to recognise Silicon Image SATA,
Nvidia, ATI, Serverworks and other controllers.

Re: AMD Sempron

only socket A semprons are k7s.
from AMD's site the 3300+ socket 754 is stepping D0, E3 or E6.

the E3/E6 is a 64-bit Palermo core with mmx/sse2/3dnow! with a 16bit 800Mhz HT link.
the D0 is the same but might (!) not support 64bit and the cache sizes are half as bug.
(64/128 vs. 128/256).

Bloody hell.  Let's just simplify the whole mess and give them all a  
brand name of CPU™.

I've have a new plan:  I'll buy the Sempr0n box to use as a  
replacement for my BSD server, and run Plan 9 on the old box (a Via  
C3 Nehemiah).  This works better anyway, as the Via "server" will  
actually fit on the boat

Re: AMD Sempron

it's not that bad.  they're all K8s with different steppings.  what you don't 
know is the cache size or if it's got 64-bit capabilities, which kenc does not
yet support.  i don't think what you don't know will be a problem in this
case.

it's interesting with all the marketing going on right now you need to be
quite savvy to figure out what you're really getting.  a bit like the days of
hand-built computers.

Re: AMD Sempron

yes. you can fuss over the micromanagement that
ekes out every fractional % of performance but unless
you are in a very specialised environment that's
just obsession. the chips either implement the
instruction set and architectural features you expect
or they don't. plan9 expects little from the cpu.

as usual, what's round about the cpu is the problem,
graphics, network, and now to some extent usb (and
sata?) being the primary concerns for support. but,
of course, device drivers aren't hard (are they? if
they were why do other operating systems have so many,
coded by such obviously mediocre programmers?), so a
little elbow grease should fix that.

When I build them by hand I *know* what I'm getting.  That's the  
problem here 

Anyway, if the little bugger will play nice as a 32-bit CPU I suppose  
I'm okay.  But that BSD machine could use a kick in the pants, so I  
think I'll stick to the plan, anyway.

And I don't even want to ask about the G5 box I'm working on getting  
my fingers on.

Not having played with any of the 64 bit intel/amd gear I'm not  
really comfortable with having to figure out the hard way just how  
"compatible" they are with 32 bit mode, despite (or in spite of)  
claims made by the manufacturers.  Hardware is just too fscking  
weirde these days.

Re: AMD Sempron

they're 100% compatable in 32bit mode.
