AMD GPU switching graphics using the prime

Good day,

I have an AMD CPU a4-5000 (kabini 8330 gpu)
and an external graphics 8570m (Oland - Engineering Names).
These are very low-end harware.

It only uses integrated (kabini - Engineering Names). I'd like the option to switch to an external gpu sometimes using prime.
 
I use a mesa-git http://pkgbuild.com/~lcarlier/mesa-git/ repo and I tried now also the latest mesa-git from AUR https://aur.archlinux.org/packages/mesa-git/ with dri3-enable.
Installation and start a new graphic interface will flawlessly.

According to the site, I tried https://wiki.archlinux.org/index.php/PRIME
xrandr --listproviders
But it only displays (kabini)
Providers: number : 1
Provider 0: id: 0x84 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 3 associated providers: 0 name:KABINI @ pci:0000:00:01.0

When I will choose:
DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
It will return a:
OpenGL renderer string: Gallium 0.4 on AMD HAINAN (DRM 2.43.0, LLVM 3.9.0)
In fact, I do not Hainan but I have Oland (Engineering Names)....
This, according temperature sensor displays for about 3 seconds activate external gpu and then turn back to (kabini).

Please Ask me how to properly deploy.

Re: AMD GPU switching graphics using the prime

same thing happens on A10(w\ Aruba) + R7 M260(Topaz). neither radeon nor amdgpu works. only one list provider.
