Hi Peter,

Since I did not have /dev/cpu I did after some searching:

for i in 0 1 2 3; do
mkdir -p /dev/cpu/$i
mknod -m 444 /dev/cpu/$i/msr c 202 $i
mknod -m 444 /dev/cpu/$i/cpuid c 203 $i
done
modprobe msr

Then:

# hexdump -s 0xc0010015 -n 8 -C /dev/cpu/0/msr
# echo $?
0
# cat /proc/version
Linux version 2.6.24-1-amd64 (Debian 2.6.24-4) (waldi@debian.org) (gcc
version 4.1.3 20080114 (prerelease) (Debian 4.1.2-19)) #1 SMP Mon Feb 11
13:47:43 UTC 2008

When I look at hexdump -v it's only zeroes for as long as I run it.

What am I doing wrong?

Thanks for your help!

Laurent
