--- Comment #2 from Dhinakaran Pandiyan <dhinakaran.pandiyan at intel.com> ---
PSR on BDW isn't supported currently.

But, here's something you can try on top of drm-tip
(https://cgit.freedesktop.org/drm-tip)
https://patchwork.freedesktop.org/series/50654/


As documentation for future BDW enablement, it'd be great if you also attach
the output of 
edid-decode /sys/class/drm/card0-eDP-1/edid and
/sys/kernel/debug/dri/0/i915_edp_psr_status
