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
