Enable GPU switching on the pre-retina MacBook Pro (2008 - 2013), v5. The main obstacle on these machines is that the panel mode in VBIOS is bogus. Fortunately gmux can switch DDC independently from the display, thereby allowing the inactive GPU to probe the panel's EDID. In short, vga_switcheroo and apple-gmux are amended with hooks to switch DDC, DRM core is amended with a

...t gmux is present, the driver would never load, even if we're the active GPU. (vga_default_device() would evaluate to NULL and vga_switcheroo_handler_flags() would evaluate to 0.)

Any takers? Merging this would allow fdo #61115 to be closed (currently assigned to intel-gfx). FWIW this series has in the meantime been tested by more folks: Tested-by: Pierre Moreau <pierre.morrow at free.fr> [MBP 5,3 2009 nvidia MCP79 + G96 pre-retina 15"] Tested-by: Paul Hordiienko <pvt.gord at gmail.com>...

...ktop.org/archives/dri-devel/2015-April/081515.html Patches 1 - 17 enable GPU switching on the pre-retina MacBook Pro. These were tested successfully by multiple people and solve two tickets in Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=88861 https://bugs.freedesktop.org/show_bug.cgi?id=61115 Patches 18 - 22 are a preview of how we're tackling retina support. Those are marked experimental and are NOT ready to be merged yet. Feedback on them is welcome. The patches are based on drm-next. They were tested on the following hardware (thanks a lot everyone!): Tested-by: Paul Hordiienk...
