Thermal Monitor

hi,
Anybody know how to get cpu sensor temperature. I analyze core temp and
other software, i know they all get data from msr by use rdmsr and wdmsr
instruction. I record the ecx, but i cannot find which ecx meaning. For
example, my cpu is amd, look through the amd manul,i am not find the
MSRC0010042 's description.
Anybody know this, please tell me.
Thank you.

Hello Tommy,


I solved with an intel cpu.
I had to write a driver because the read msr funtion runs at ring 0 level.
Intel CPUs have a MSR register which tells you temperature in centigrade
degres.
Intel manuals describe (Volume 1, 2, 3, 3A, 3B) describe all information you
need, so I think it's the same in AMD cpu's.
