Subject: [lm-sensors] coretemp support for Core i5 CPU
Date: Sun, 20 Sep 2009 07:47:43 +0000 [thread overview]
Message-ID: <4AB5DE1F.1020004@gmail.com> (raw)
Trying to load the coretemp driver for CPU temperature monitoring on a
Core i5 750 CPU gives:
coretemp: Unknown CPU model 1e
coretemp: Unknown CPU model 1e
coretemp: Unknown CPU model 1e
coretemp: Unknown CPU model 1e
Looks like this model needs to be added to the list in
drivers/hwmon/coretemp.c. Though this doesn't really seem like a very
good approach as we'll keep having to update this driver whenever a new
CPU model gets released. Intel has a CPUID field that indicates if the
thermal sensor is supported: "The processor supports a digital thermal
sensor if CPUID.06H.EAX[0] = 1." We should likely be using this instead
of hard-coded CPU model checks..
