CUDA.Mem.unregister fails with CUDA.jl 5.4 (not with 5.3)

[omlins]

It seems like the method register(::CUDA.HostMemory) required by CUDA.Mem.unregister has been removed.

The error message is the following (observed in the unit tests from ImplicitGlobalGrid.jl):

  MethodError: no method matching register(::CUDA.HostMemory)
  
  Closest candidates are:
    register(::Type{CUDA.HostMemory}, ::Ptr, ::Integer, ::Any)
     @ CUDA /scratch/snx3000tds/julia/omlins/daint-gpu/packages/CUDA/Tl08O/lib/cudadrv/memory.jl:167

     @ CUDA /scratch/snx3000tds/julia/omlins/daint-gpu/packages/CUDA/Tl08O/lib/cudadrv/memory.jl:167
  
  Stacktrace:

This is a typo in the method deprecation. I'd advise moving away from those deprecated functions though.

@maleadt : thanks!

I'd advise moving away from those deprecated functions though.

Could you tell me how this functionality is exposed in future? Which order functions to be used?

[maleadt]

See https://juliagpu.org/post/2024-05-28-cuda_5.4/; the Mem submodule has been removed.

@maleadt Could you release soon a new version? We keep running into this error here... Thanks!

[maleadt]

Sure, there's a couple of PRs I want merged, but I'll tag a release after that.

Isn't it easier to just fix the use of the deprecated function though?
