There’s been a couple of PRs, but nothing GPU specific ([https://github.com/JuliaLang/julia/pull/31563](https://github.com/JuliaLang/julia/pull/31563), [https://github.com/JuliaLang/julia/pull/25558](https://github.com/JuliaLang/julia/pull/25558)). Here’s something similar to Adapt.jl: [https://github.com/JuliaGPU/GPUArrays.jl/issues/147#issuecomment-417255267](https://github.com/JuliaGPU/GPUArrays.jl/issues/147#issuecomment-417255267). I know @keno had some thoughts about this too, but I don’t think he’s had the time to do anything with them.
