Description wendy.wang 2014-12-25 12:19:36 UTC 
In all branches, by default kernel setting, PSR feature is disabled by default for PSR supported platforms.

Submit this bug is aims to mark PSR feature current status.

Expected Behavior：
PSR as a POR feature, should be enabled by default, but currently because of the issue, this feature has been disabled.

If want to enable, must add "i915.enable_psr=1" parameter in kernel.

per Daniel's suggestion, these "disabled" features should be marked as "enhancement"

And really, these should be tracked in JIRA, not bugzilla. Closing.
