Comment 2 Tomas W 2016-04-01 19:19:38 UTC 
Ah might add its an A10 8700p APU (With built in R6 Carrizo) and "external" gpu is supposed to be an R7 Topaz

The driver appears to be loading fine according to your xorg log and dmesg output.

[    10.084] (--) AMDGPU(G0): Chipset: "TOPAZ" (ChipID = 0x6900)

Seems to work with kernel 4.5, tho no powerplay for the topaz gpu so its very very slow =)
Comment 6 Michel Dänzer 2016-04-04 02:35:10 UTC 
Resolving per comment 5.

BTW, with DRI3 enabled, you don't need to fiddle with xrandr --listproviders and friends at all; Mesa automagically uses the other GPU with DRI_PRIME=1.
