Subject: [Bug 88861] [efi, i915, vgaswitcheroo, black screen, nouveau] Screen goes black when switching from dedicated nvidia graphics card (nouveau) to integrated

--- Comment #9 from Lukas Wunner <lukas@wunner.de> ---
Hi Jani,
Paul Hordiienko, the reporter of this bug, successfully tested an earlier
version (v2) of the patch set, see the Tested-by: tags on these patches:
http://lists.freedesktop.org/archives/dri-devel/2015-August/thread.html#88156
The most recent version (v5) was tested on the following machines:
Tested-by: Pierre Moreau <pierre.morrow@free.fr>
[MBP 5,3 2009 nvidia MCP79 + G96 pre-retina 15"]
Tested-by: William Brown <william@blackhats.net.au>
[MBP 8,2 2011 intel SNB + amd turks pre-retina 15"]
Tested-by: Lukas Wunner <lukas@wunner.de>
[MBP 9,1 2012 intel IVB + nvidia GK107 pre-retina 15"]
(The patches as posted miss the Tested-by: tags by Pierre and William since I
posted them before getting their feedback.)
The patch set worked just fine on my machine and William Brown's.
On Pierre Moreau's machine the discrete GPU locks up when woken. It used to do
that in the past as well but only after about 10 switches, now it's locking up
every time. My guess is that this is a regression in nouveau on the G96 since
it works fine on my GK107.
Paul Hordiienko's machine is an MBP 6,2 2010 with intel ILK + nvidia GT216. So
architecturally it is similar to my machine (integrated Intel and discrete
Nvidia) and since v2 worked fine, I expect that v5 would work as well (FWIW).
