    drm/i915: Disable LVDS port after the pipe on PCH

    Follow the correct pipe vs port disable sequence for the PCH LVDS
    ports, ie. disable the port after the pipe.

    Other PCH port were already converted in the following commits:

That doesn't make sense since neither of the affected platforms have LVDS.
Comment 4 cprigent 2015-07-25 15:39:18 UTC 
Reproduced on SKL with kernel 4.2-rc2. External screen works.
It is no more reproduced on BSW.

We found a "workaround":
1. suspend to RAM (command: echo mem > /sys/power/state)
2. Wait external screen goes to power save mode
3. Resume -> Display works on eDP screen

Comment 5 Patrik Jakobsson 2015-07-26 21:30:18 UTC 
Hi Christophe

As Ville says, the bisected commit is not related to this afaict. The problem seems to appear randomly on my SKL-Y so you probably just got unlucky.

I think this is related to a bug in the hw readout code (could be same as https://bugs.freedesktop.org/show_bug.cgi?id=91428) or the DP link training issue you're seeing in the dmesg. Both issues are causing quite a lot of igt fails on SKL.

I'll look into this tomorrow since it seems quite urgent.
Comment 6 cprigent 2015-07-27 21:54:09 UTC 
Not reproduced with kernel drm-intel-nightly c1380a01867fd3cc7922a5152186e1aac7118b35 (4.2.0-rc3) from git://anongit.freedesktop.org/drm-intel
I don't resolve it at the moment, in case this is randomly reproduced.

Comment 9 Gavin Hindman 2015-08-03 07:30:40 UTC 
Have you tried to pass either i915.edp_vswing=1 or =2 as a boot option?  This is a driver workaround for incompatible panel vswing values in the default uEFI VBT.  This seems to be bouncing in and out randomly per uEFI release.

Still reproduced with last setup (update this Monday). We will add panel references for better understanding.
