Coppermine is the code name of the low level arch of the chip. Really, the kernel should be querying the builder: Have you a Deschutes, a Mendocino or a Coppermine ? How much cache do you have ? But that is rarely known (Uh? I bought a Pentium III). You have to guess from the answer to: Have you a PII, an old Celeron (Mendocino) or a new Cel-PIII (Copper). -- J.A.

Until recently it was using the 3dnow memcopy stuff. It got disabled when the memcopy stuff was overhauled to give even bigger wins on the Athlon. Which makes sense given that there are a lot more Athlons out there than Winchips. Who knows, maybe the old 3dnow! copy routine will make a comeback in a future kernel just for Winchip-2As and above. Just needs someone to find the time. regards, Davej. -- | Dave Jones.http://www.suse.de/~davej | SuSE Labs - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

Celeron (Coppermine).
