Is /dev/thinkpad a directory ?Re: [ltp] CPU Speed...

[Julien Tane]

Well I just made the command:

> su -c 'chmod 755 /dev/thinkpad'


I also read a bit of the README file from the tpctl 5.0. But it seems 
that /dev/thinkpad is a character device
currently :
crwxr-xr-x    1 root     thinkpad  10, 170 Jan 22 13:35 /dev/thinkpad

where as the README says:

>    mkdir --mode=755 /dev/thinkpad

which means it is a directory.
