Configuring AMD RADEON 520 in a Hybrid graphics setup with Wayland

[Kanfused]

Hi,
The tl;dr about this question is - Is my radeon 520 dedicated card working fine? Do I need to set "xrandr --setprovideroffloadsink radeon Intel" in Wayland to configure hybrid graphics? Xrandr is not working well in weston/wayland.

Long version:
I installed Ubuntu 17.10 on my newly bought HP Laptop (Model: HP 15-BS576TX) which has a dedicated AMD 520 2GB DDR3 graphics card and Intel HD 620 onboard graphics in a Kabylake Core i5 processor system. This is the first time I'm installing Linux on a hybrid graphics card setup on a laptop.

Now, Ubuntu 17.10 defaults with Xwayland instead of Xorg/XFree86. I find it confusing to configure AMD Radeon 520 dedicated graphics. The confusing part is xrander --listproviders only list the intel hd 620 integrated graphics.

xrandr --listproviders 
Providers: number : 0

But, lspci -knnn shows that AMD Radeon 520 card is detected:

01:00.0 Display controller [0380]: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430 / R7 M520] [1002:6660] (rev 83)

and Integrated Intel HD 620 graphics:

I'm booting with "radeon.modeset=1" which is added to the grub bootloader entry.

Now, if I run any app with DRI_PRIME=1 it works and shows below info:

 :~$ DRI_PRIME=1 glxinfo |grep -i Opengl*
OpenGL vendor string: X.Org
OpenGL renderer string: AMD HAINAN (DRM 2.50.0 / 4.13.0-16-generic, LLVM 5.0.0)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.2.2
OpenGL core profile shading language version string: 4.50

So, I assumed Radeon 520 is working fine. Then, noticed that there is no mention of gallium 3d? But, why Xrandr is not showing dedicated card as one of the providers?

I see that there is amdgpu driver module also loaded. From the list, R520 card seems to be supported by the radeon driver.

 
 lsmod |grep radeon
radeon               1470464  0
ttm                    94208  2 amdgpu,radeon

drm                   356352  28 amdgpu,radeon,i915,ttm,drm_kms_helper

Wnat needs to be done now? I have no custom scripts or files placed in /etc/X11 directory .
