SubjectRe: [PATCH] Processor autodetection (when configuring kernel)
Giacomo,

I don't think cpu_info.sh is quite right. It identified my 500 Mhz Pentium
III as CONFIG_M386. I think CONFIG_M686 is closer, but as I don't know the
significance of all the flags (MMX, TSC, etc), I'm not certain. Since the
flags do include fxsr, the correct answer may be CONFIG_M686FXSR.

Anyhow, here are my results:

[relson@osage relson]$ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 7
model name : Pentium III (Katmai)
stepping : 3
cpu MHz : 501.147
cache size : 512 KB
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36
mmx fxsr xmm
bogomips : 999.42

[relson@osage relson]$ ARCH=i386 ; . cpu_detect.sh
GenuineIntel:6:7
CONFIG_M386

Also, here's a patch to make the script echo CONFIG_M686:

diff -urN cpu_detect.sh.orig cpu_detect.sh

P.S. I'm running 2.2.18, if it matters.
