With commit c814a4c7c4aad795835583344353963a0a673eb0, the meaning of tempX_max
was changed. It no longer returns the value of bits 8:15 of
MSR_IA32_TEMPERATURE_TARGET, but instead returns the value of CPU threshold
register T1. tempX_max_hyst was added to reflect the value of temperature
threshold register T0.As it turns out, T0 and T1 are used on some systems, presumably by the BIOS.
Also, T0 and T1 don't have a well defined meaning. The thresholds may be used
as upper or lower limits, and it is not guaranteed that T0

On old CPUs (and even some recent Atom CPUs) TjMax can't be read from
the CPU registers, so it is guessed by the driver using a complex
heuristic which isn't reliable. So let users who know their CPU's
TjMax pass it as a module parameter.Signed-off-by: Jean Delvare

This patch adds the core and pkg support to coretemp.
These thresholds can be configured via the sysfs interfaces tempX_max
and tempX_max_hyst. An interrupt is generated when CPU temperature reaches
or crosses above tempX_max OR drops below tempX_max_hyst.This patch is based on the documentation in IA Manual vol 3A, that can be
downloaded from here:

This patch merges the pkgtemp with coretemp driver.
The sysfs interfaces for all cores in the same pkg
are shown under one directory, in hwmon. It also
supports CONFIG_HOTPLUG_CPU. So, the sysfs interfaces
are created when each core comes online and are
removed when it goes offline.Signed-off-by: Durgadoss R

Following patch adds support for mobile Penryn CPUs. Intel documents this
poorly. I asked the Coretemp author for some help. This is totally untested and
may not work. Please test!Signed-off-by: Rudolf Marek

Fix Atom CPUs support. Intel documents TjMax at 90 degrees C but
some Atoms may have 125 degrees C (this is undocumented speculation).Signed-off-by: Rudolf Marek

This patch adds support for family 0x17, which has Penryn Core. It should also
cover the 8 cores Xeons.Can someone test please? I think it should work.
