drm/i915: Enable PSR by default on Valleyview and Cherryview.
With a reliable frontbuffer tracking and all instability corner cases solved for this platform let's re-enabled PSR by default. In case a new issue is found and PSR is the main suspect, please check if i915.enable_psr=0 really makes your problem go away, please report it at bugs.freedesktop.org. In a bugzilla entry for PSR is desirable: - dmesg (drm.debug=0xe) - output of /sys/kernel/debug/dri/0/i915_edp_psr_status - Platform information. Vendor, model, id, pci id. - Graphical environment: Gnome, KDE, openbox, etc... - Details how to reproduce. - Also good if you could run PSR test cases of Intel-gpu-tools - Please mention if forcing main link standby or main link off helps you. There are Intel-gpu-tools test cases that can be helpful to determine if PSR is working as expected: kms_psr_sink_crc and kms_psr_frontbuffer_tracking.
