<pre>PSR on BDW isn't supported currently.
But, here's something you can try on top of drm-tip
(<a href="https://cgit.freedesktop.org/drm-tip">https://cgit.freedesktop.org/drm-tip</a>)
<a href="https://patchwork.freedesktop.org/series/50654/">https://patchwork.freedesktop.org/series/50654/</a>
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
-DK</pre>
