[Intel-gfx] [PATCH 5/5] drm/i915: Enable PSR by default.

[Rodrigo Vivi]

Another questions,

Are you using powertop --auto-tune?

If so, can you please try to repdoruce X slowness issue on these 2 scenarios:
1. without doing the powertop auto-tune and psr enabled.
2. with powertop auto-tune but with PSR disabled by i915.enable_psr=0

Thanks in advance,
Rodrigo.
