Two problems:
1) /dev/smb* are exclusive access -- only one process can hold them open
at a time. (As of a couple of months ago in -stable at least)
2) You still need knowledge of the chipsets. This isn't an abstracted
interface.
What would work better is:
% cat /dev/mbmon
cpu[0] temp=73 fan=180 vcc=2.30 ...
cpu[1] temp=76 fan=167 vcc=2.32 ...
motherboard temp=38 <-- generic motherboard sensor values
fan[0]=313 <-- rpm for non-cpu fans
fan[1]=-1
.
.
.
%
I.e., something suitable for direct display, and which can easily
be ripped apart with awk to extract specific values. It should also
be possible to ioctl the device in a manner similar to /dev/apm,
although defining the variables and data types for the ioctl
interface might be a bit of a pain, since the variables returned
by the different chips are, well, variable.
