Ethereum & OpenCL: ROCm vs. AMDGPU-PRO 17.40

[lucrus]

So, are amdgpu (not -pro) and a 4.18 kernel on any distro enough to run ethminer with rocm, on my hardware which happens to be a Saberthooth 990FX R2.0 (no PCIe atomics AFAIK), AMD FX 8350 CPU and a RX580 GPU?

Not sure if we still have atomics requirement for 580 - I believe it was relaxed for Vega but not sure about earlier parts.

Ignoring atomics for a minute, you would need something like:

- latest WIP 4.18 kernel (580 support went into 4.17 but fixes kept going up after that),

- Felix's WIP thunk with upstream-compatible IOCTL calls,
https://github.com/RadeonOpenCompute...d/drm-next-wip

- the rest of the ROCm stack above ROCT (so ROCR and up).

I haven't tried that myself but I think it should work. Without the matching thunk nothing will work on upstream kernel because the IOCTLs won't line up.

All this should also fetch up in the ROCm 1.9 release fairly soon.
