https://github.com/RadeonOpenCompute/ROCm ROCm has open-source support for OpenCL 1.2 but doesn't yet work on all mainline components (i.e. Linux kernel and LLVM changes needed), but that should change in 2018, and also only works with relatively recent AMD GPUs.

That looks very interesting. I'm OK with it only supporting recent AMD GPUs, but I hope the other changes will be upstreamed soon.
