Unable to find correct HIP path

[eirikfagerbakke]

Hi!
I am kind of a noob when it comes to GPU programming, so apologies if this is a trivial question.
When calling AMDGPU.versioninfo(), the path listed for HIP is "C:\\WINDOWS\\SYSTEM32\\amdhip64.DLL". This is however an old version, and I think the correct version should be "C:\\Program Files\\AMD\\ROCm\\6.1\\bin\\amdhip64_6.DLL". I have tried deleting the old amdhip64.dll file, but then AMDGPU isn't able to build. Everything else seems to find the correct path.
I also do not have MIOpen, but from what I can understand, this is only available on Linux. Is this a big problem?
I am specifically going to be using AMDGPU with Lux.jl.

Is there any way I can manually change the HIP path? Or should I finally just switch over to Linux?
Any help would be greatly appreciated.

We probably need to change this line to account for the change in name (amdhip64_6):

AMDGPU.jl/src/discovery/discovery.jl

Line 137 in 7bec32c

Sys.islinux() ? "libamdhip64" : "amdhip64";

MIOpen is used for convolutions so it you need them, then it is probably better to swtich to Linux :)

I tried changing it just now, but I now get the error ERROR: InitError: HIPError(code hipErrorNoDevice, no device found) after re-building and simply running using AMDGPU. I also tried just naively changing the file name to "amdhip64", but then I got errors from the other ROCm files.

Aa okay, good to know! I think I might give Linux a try then :)
