hwmon: (ibmpowernv) Add current(A) sensor

2017-06-20T20:52:19+00:00

hwmon: (ibmpowernv) introduce a legacy_compatibles array

2017-06-20T20:51:45+00:00

Today, the type of a PowerNV sensor system is determined with the "compatible" property for legacy Firmwares and with the "sensor-type" for newer ones. The same array of strings is used for both to do the matching and this raises some issue to introduce new sensor types. Let's introduce two different arrays (legacy and current) to make things easier for new sensor types. Signed-off-by: Cédric Le Goater Tested-by: Shilpasri G Bhat Signed-off-by: Guenter Roeck

hwmon: (ibmpowernv) Add highest/lowest attributes to sensors

2017-06-12T00:08:19+00:00

OCC provides historical minimum and maximum value for the sensor readings. This patch exports them as highest and lowest attributes for the inband sensors copied by OCC to main memory. Signed-off-by: Shilpasri G Bhat Signed-off-by: Guenter Roeck

hwmon: (ibmpowernv) Fix label for cores numbers not threads

2016-09-13T14:27:05+00:00

Currently the label says "Core" but lists the thread numbers. This ends up looking like this: # cat /sys/class/hwmon/hwmon0/temp[1-4]_label Core 0-7 Core 8-15 Core 16-23 Core 24-31 This is misleading as it looks like it's cores 0-7 when it's actually threads 0-7. This changes the print to just give the core number, so the output now looks like this: # cat /sys/class/hwmon/hwmon0/temp[1-4]_label Core 0 Core 8 Core 16 Core 24 Signed-off-by: Michael Neuling Acked-by: Cédric Le Goater Signed-off-by: Guenter Roeck

hwmon: (ibmpowernv) Fix build error seen for some configurations

hwmon: (ibmpowernv) pretty print labels

2015-04-08T17:34:20+00:00

The new OPAL device tree adds a few properties which can be used to add extra information on the sensor label. In the case of a cpu core sensor, the firmware exposes the physical identifier of the core in the "ibm,pir" property. The driver translates this identifier in a linux cpu number and prints out a range corresponding to the hardware threads of the core (as they share the same sensor). The numbering gives a hint on the localization of the core in the system (which socket, which chip). Signed-off-by: Cédric Le Goater Signed-off-by: Guenter Roeck

hwmon: (ibmpowernv) add a label attribute

2015-04-08T17:34:20+00:00

Currently, sensors are only identified by their type and index. The new OPAL device tree can expose extra properties to identify some sensors by their name or location. This patch adds the creation of a new hwmon *_label attribute when such properties are detected. Signed-off-by: Cédric Le Goater Signed-off-by: Guenter Roeck

hwmon: (ibmpowernv) add support for the new device tree

2015-04-08T17:34:20+00:00

The new OPAL device tree for sensors has a different layout and uses new property names, for the type and for the handler used to capture the sensor data. This patch modifies the ibmpowernv driver to support such a tree in a way preserving compatibility with older OPAL firmwares. This is achieved by changing the error path of the routine parsing an OPAL node name. The node is simply considered being from the new device tree layout and fallback values are used.

hwmon: (ibmpowernv) add a helper routine create_hwmon_attr

This should shorten a bit the code necessary to create a hmwon attribute. Signed-off-by: Cédric Le Goater Signed-off-by: Guenter Roeck
