Another item from the meeting...
Whether the x86 CPU is 32 or 64 bit, and how many cores there are. `cat
/proc/cpuinfo' shows `flags', the interesting ones being the modes,
rm=real-mode=16-bit, tm=transparent=32, and lm=long=64. This awk shows
the flags and how many CPU entries there are.
$ awk '$1 == "flags" {for (f = 3; f <= NF; f++) if ($f ~ /^[rtl]m$/) m[$f]
= 1; c++}
> END {for (t in m) printf "%s ", t; print c}' /proc/cpuinfo
tm lm 4
$
Separately, there's whether the kernel is 32 or 64-bit. It's possible
to run a 32-bit kernel on a 64-bit CPU but it's not making best use of
the hardware. `uname -m' shows `i686' for 32-bit, `x86_64' for 64.
Cheers, Ralph.
