Hmmm ...

Despite its name, the Intel Core (Yonah) is more similar to the Pentium M than to the Intel Core 2.

I see, so yeah, you should use Pentium M, it's the closest thing.

Thank you guys for your help! I'll see if I can find out some solution for udev and I'll let you know.

poof.. dust off this thread. I think I've found the 'correct' answer to the which processor question.

i just took the time to recompile a 2.6.21.1 kernel, and from the CPU selection options it seems that you can find out which to select like this:

Code:

# cat /proc/cpuinfo | grep family
cpu family      : 6
cpu family      : 6

if your family is >= 6, then you want to select the "Core 2/newer Xeon"

CPUs. You can distingush newer from older Xeons by the CPU family
in /proc/cpuinfo. Newer ones have 6.

Hmmm ... but it says here:

Quote:

Intel identifies its various processor using a combination of the family and model codes. Pentium processors are identified by a family code of 5. A family code of 6 covers the PentiumPro and all of its variants. Since the PentiumPro, Pentium II, Pentium III and Celeron are all based on the same processor architecture, they are all part of the P6 family( hence, family code 6). The model code is used to tell the various P6 processors apart, along with the cache size and brand ID, depending on the CPU (it's messy; don't ask).

So, the model number is more important.

I'm looking for a nice table of family and model codes and related processor types ... all I could find so far is this:

Unfortunately, it's not enough, it doesn't list them all.

well, i did recompile with the Core 2/Xeon processor selected and it _seems_ a touch faster, compile bzImage down ~10s and memory use seems less. not that I pay too much attention but before it seems conky reports ~30% usage and now its typically ~15-20% usage. (1GB total)

??? i am dumbfounded.. . nothing new i guess
