Yes, I try to do that.

xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x7e cap: 0xf, Source Output, Sink Output, Source Offload, Sink
Offload crtcs: 4 outputs: 4 associated providers: 0 name:radeon
Provider 1: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink
Offload crtcs: 6 outputs: 1 associated providers: 0 name:radeon

xrandr --setprovideroffloadsink 0x7e 0x46

And it ruined my xorg completely. X fall out in to the shell without any
errors.

I could switch between graphics card on flgrx driver with "aticonfig --px-dgpu"
and "aticonfig --px-igpu". It worked well.
But now, it seems that I stuck in low power graphics mode and I can't switch to
my power card. '

glxinfo always show me AMD ARUBA chip:

glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Gallium 0.4 on AMD ARUBA (DRM 2.43.0, LLVM 3.7.0)

DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Gallium 0.4 on AMD ARUBA (DRM 2.43.0, LLVM 3.7.0)

DRI_PRIME=0 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Gallium 0.4 on AMD ARUBA (DRM 2.43.0, LLVM 3.7.0)
