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

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

This patch series makes suspend support in qemu alot more useful. Right now the guest can put itself into s3, but qemu will wakeup the guest instantly. With this patch series applied the guest will stay suspended instead and there are a few events which can kick the guest out of suspend state: A monitor command, ps/2 input, serial input, rtc. Not much yet, but it''s a start with the

A call to drm_simple_encoder_init() initializes an encoder without further functionality. It only provides the destroy callback to cleanup the encoder's state. Only few drivers implement more sophisticated encoders than that. Most drivers implement such a simple encoder and can use drm_simple_encoder_init() instead. The patchset converts drivers where the encoder's instance is embedded in
