Description Liang Huang 2000-01-17 23:19:32 UTC

I just installed 6.1 on a dual PIII-650 coppermine system.  Taking a look
at /proc/cpuinfo I see both CPU's get identified as coppermines but it
reports 0 for the cpus' cache size.  Does this mean that the kernel is not
using any of the cache on the chip.  Sorta defeats the purpose of even
having the coppermines.

The problem also occurs with the 650MHZ mobile Pentium III (Coppermine) with
256KB cache in my Dell Inspiron 7500 notebook. Here is  the contents of
/proc/cpuinfo:
