I can help testing code for 4.17/++ if you wish but that is *different* storry.
Quick tested an 4.16.0-11490-gb284d4d5a678 , amdgpu and radeon driver are broken now in this one.
radeon tells:
...
[ 6.337838] [drm] PCIE GART of 2048M enabled (table at 0x00000000001D6000). [ 6.338210] radeon 0000:21:00.0: (-12) create WB bo failed [ 6.338214] radeon 0000:21:00.0: disabling GPU acceleration
...
I have the same Issue now on final 4.17.
Also I played with BIOS options also which does not fix anything but changes the error message.
IOMMU && SR-IOV disabled the error changes to this :
[ 7.092044] [drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0 test failed (scratch(0x850C)=0xCAFEDEAD) [ 7.092059] radeon 0000:21:00.0: disabling GPU acceleration
While I could workaround SWIOTLB bugs in 4.15 and 4.16 , 4.17 seems to kill the GPU with no way for me to make it work ( at least I could not find any workaround by now )
