I just copy out the hw/xfree86/drivers/modesetting, and make it build
with the system xserver-xorg-dev like a normal DDX (ie. xserver-xorg-video-ati).
But I don't think this makes any difference if you build the patched whole
Xserver to generate modesetting_drv.so. I think the RenderXXX option
is the point to find why your modesetting_drv.so can't work.

Qiang

Ok, now you need to teach me how you did that magic trick. Mind you, the
fan is running non-stop, but I don't care.

Yes, I tested on Ubuntu 16.04 and it's OK. But I haven't tried to build
the whole Xserver to get the modesetting_drv.so, instead I build it separately.
Attach my modesetting DDX and you can copy it to
/usr/lib/xorg/extra-modules/drivers/
for a try.

Ah, and your configuration works? I'll have to look closer into the
difference between Ubuntu and Mint.
As promised, here are the files:
The log file (again):
https://www.dropbox.com/s/cqklcqjn18aer3m/Xorg.0.log?dl=0
And the build-source files:

1.18.3 is OK. And I use Ubuntu 16.04.
The RenderPath and RenderDriver are necessary for modesetting
to select a different render GPU than the display GPU.

Greetings Qiang,
What version of X are you using? I've built my own with what Mint
currently is offering, which is apparently 1.18.3, but it seems to be
behind whatever you are using. I'll have the full source (with the
modifications) available for you as soon as DropBox finishes synching
everything with my laptop (went with a clean install, it may be a few
hours...). Until then, I've attached the Xorg.log, if you're interested.
For whatever reason it did not care for the "RenderPath" and
"RenderDriver" sections.
Ah, and one line needed to be added 'driver.c' to get it to compile:
"#include <gbm.h>". Aside from that, once all dependencies were
satisfied, it compiled well.
Many Thanks,
Ryan

Hi Ryan,
That's interesting. I also want to do this but in another way:
one modesetting DDX display on iGPU and render on dGPU
Attach the prototype patch and the xorg.conf should be
Section "ServerFlags"
Option "AutoAddGPU" "off"
EndSection
Section "Device"
Identifier "Intel"
Driver "modesetting"
Option "RenderPath" "radeon"
Option "RenderDriver" "radeonsi"
EndSection
Regards,
Qiang

Subject: Making the discrete AMD GPU the default GPU in a Mux-less setup with
an integrated Intel GPU in Mint 18 (Xenial)
Greetings,
I have a Toshiba Satellite P55T-B5340 that I am attempting to persuade
to boot X using the discrete GPU, and only the discrete GPU. It's been a
lot of fun, because it's muxless (no hardware switch, vgaswitcharoo
seems only to crash it), and the GPU I want to use has no dedicated
outputs (and so, somehow, has to steal them from the integrated GPU,
using magic from what I can tell...). I've attempted to adapt the Nvidia
approach, which sadly only appears to work for glxinfo; attempts to use
"modesetting", screens, and AllowEmptyInitialConfiguration appear to
have no (positive) effect on X, as it really wants this GPU to be hooked
up to some form of output (or it will unload the module). On the upside,
the discrete GPU is quite happy with the 'radeon' driver.
Additional Information:
The iGPU is an Intel HD 4600 Graphics (CPU is a i7-4710HQ).
The dGPU is an AMD/ATI Venus Pro (Radeon HD 8850M / R9 M265X).
Output from xrandr --listproviders is as follows:

Pages I've looked at, solutions I've tried:
https://wiki.archlinux.org/index.php/PRIME
https://www.mankier.com/5/xorg.conf#Outputclass_Section
http://us.download.nvidia.com/XFree86/Linux-x86/364.15/README/randr14.html
and a search through both Google and this greater mailing list for
'discrete gpu', finding some interesting stuff, but nothing applicable.
Has anyone some magic glitter to spare, or perhaps some working
knowledge of how I might get this beast into the proper configuration?
Many Thanks,
Ryan
