Deprecated, please use AMDGPU.jl
Currently, the requirements to get everything working properly is a bit poorly documented in the upstream docs for any distro other than Ubuntu. So here is a list of requirements I've found through the process of making this work:
Make sure /dev/kfd has a group other than root that you can add your user to. I recommend adding your user to the "video" group, and setting the ownership of /dev/kfd to root:video with 660 permissions. Or, run as root! (Don't actually do this)
The correct libraries in your LD_LIBRARY_PATH or standard library locations:
- libhsa-runtime64.so
- libhsakmt.so
In terms of Linux kernel versions, just pick the newest one you can (I'm running 4.20 as I type this). If building your own kernel, make sure all the regular AMDGPU and HSA options are enabled.
You will also need ld.lld installed on your system (provided by LLVM/Clang);
if you built Julia from source, you should have a copy somewhere in
deps/scratch/llvm-*/*/bin/ that you can add to your PATH.
Once all of this is setup properly, you should be able to ] build HSARuntime
successfully; after that, if you have a supported GPU attached and enabled, ] test HSARuntime should work exactly as you might expect.
- Document some key Linux kernel config options to have enabled
- Make deps/wrap.jl use system-installed HSA headers
