2012-10-14hwmon: (coretemp) Add support for Atom CE4110/4150/4170Guenter Roeck1-0/+1
TjMax for the CE4100 series of Atom CPUs was previously reported to be 110 degrees C. cpuinfo logs on the web show existing CPU types CE4110, CE4150, and CE4170, reported as "model name : Intel(R) Atom(TM) CPU CE41{1|5|7}0 @ 1.{2|6}0GHz" with model 28 (0x1c) and stepping 10 (0x0a). Add the three known variants to the tjmax table. Signed-off-by: Guenter Roeck <[email protected]> cc: [email protected] Acked-by: Jean Delvare <[email protected]>

2011-09-21hwmon: (coretemp) Don't use threshold registers for tempX_maxGuenter Roeck1-7/+0
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 <= T1. Thus, the new attribute mapping does not reflect the actual usage of the threshold registers. Also, register contents are changed during runtime by an entity other than the hwmon driver, meaning the values cached by the driver do not reflect actual register contents. Revert most of c814a4c7c4aad795835583344353963a0a673eb0 to address the problem. Support for T0 and T1 will be added back in with a separate commit, using new attribute names.

2011-09-21hwmon: (coretemp) Let the user force TjMaxJean Delvare1-3/+4
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.

2011-07-28hwmon: (coretemp) Add core/pkg threshold support to CoretempDurgadoss R1-0/+7
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: http://download.intel.com/design/processor/manuals/253668.pdf Signed-off-by: Durgadoss R <[email protected]> Signed-off-by: Guenter Roeck <[email protected]>
2011-05-20hwmon: (coretemp) Merge pkgtemp with coretempDurgadoss R1-7/+14
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.
