similar to: [PATCH v4 0/6] Suppor for various power sensors on GF100+

This is a complete rework from the first version I sent out. Now the implementation is more centered around the power_rails we find in the SENSE table instead of extdev centered. This makes the implementation a lot easier and straightforward. I've added support for the INA219, INA209 and INA3221 sensors found on multiple Fermi and Kepler cards. The power consumption is also exported via

This is a complete rework from the last version I sent out. Now the implementation is more centered around the power_rails we find in the SENSE table instead of extdev centered. This makes the implementation a lot easier and straightforward. I've added support for the INA219, INA209 and INA3221 sensors found on multiple Fermi and Kepler cards, but only the INA3221 bits are tested so far.

The INA3221 is usually found on mid and high end kepler+ gpus Marins Patch implements the new iccsense subdev and all needed bits for the INA3221 power sensor. My Patch implements the hwmon power1 interface to expose the current power consumption through hwmon (and can be read out via sysfs or the sensors tool) Please test these patches for Fermi+ GPUs, that nothing gets messed up and works as

The power sensors can be configured to sample the readout values over time. Nvidia does this too, so nouveau should probably do that too.

There is an optinal header field in the power budget table we can use to read out the power cap of the GPU. The meaning of this header field was confirmed with nvidia-smi -q: The rows "Min Power Limit", "Power Limit" and "Max Power Limit" are set to the "min", "avg" and "max" values from the referenced power budget entry respectively.

There is an optinal header field in the power budget table we can use to read out the power cap of the GPU. Sadly it is optional and if that field isn't sad, things beome complicated. Anyhow, this is good enough for most cards and we can use it later for capping the power consumption of the GPUs, but first, just export those values through hwmon. First design, will change stuff, want

There is an optinal header field in the power budget table we can use to read out the power cap of the GPU. We should have this in the kernel before actually using it to catch errors and see how reliable this is, but as it seems it works on all GPUs as expected on Kepler und Maxwells with the power cap field set in the vbios. This series keeps things really simple for now until we figure out

This v5 drops a check for attr_set. Versions: v1 -> v2: * Keep temp attrs as read only v2 -> v3: * Code fix-ups: struct and string as const and add return within switch due to fallthrough * Add Signed-off-by to all commits v3 -> v4: * Rever const to struct attribute. Kbuild complains. v4 -> v5: * Drops a check for attr_set in

Kbuild sent me an e-mail due to a fixup I introduced in v3. It complains due to an incompatible pointer type and it doesn't build. This version reverts it.

This v8 fixes removes dummy functions which only had a return and moves the code into the switch statements.

Hi! This patchseries replaces the deprecated hwmon_device_register function with the new one hwmon_device_register_with_info. It also does some cleanup. Here is the list of patches and what they do: 1/ Adds config structures for all sensors and their possible settings. This patch and the next one are just preparing the code for what it comes. 2/ Now everything goes through
