[Intel-gfx] [PATCH 0/5] PowerManagement Toggle for PowerTOP

[Alexandra Yates]

This project is explained in detail on the HAS
https://docs.google.com/a/intel.com/document/d/1E-en_xqfHgCnhD1Tes3f08UYrOc-etv2W-pU0ZErKdE/edit?usp=sharing  

Summary: 
Permits the user to identify and toggle values for PSR, FBC, RC6, DRRS, and IPS
under /sys/class/drm/card0/power/.  By enabling these features I'm looking to
empower our customers, such as, power team, chrome OS, and platform integration teams
to debug graphics power management features. 

>From the current patchset PSR, FBC, RC6, and, DRRS are complete and past BAT, modset,
and suspend/resume tests.  For IPS I'm looking for feedback since IPS seems to change
during runtime dynamically.  Additionally, as a future project IPS would be better 
served if it is implemented by using the atomic check, pre-commit, commit, post-commit,
a good example of this is the PSR enable/disable implementation.

For this project to be completed needs to have in place the following components:
(Need to be developed)
* IPS toggle interface flesh-out
* Tests added to intel-gpu-tools repo
* Documentation for all sysfs added interfaces
* PowerTOP component named: GFX-TOP. With the following requirements:
	* It would be available only to developers
	* It would allow the developers to toggle the interfaces from
	  the PowerTOP user interface.  
	* It would show the Power Consumption impact of toggling on and off
	  these settings.      
     
Your review of this patchset is intended to contribute to its full
maturity so that when we reach the PowerTOP development all pieces would
be ready for commit.  

Thank you in advance,
