[Issue]: amdgpu on WSL uses too much space

[morags]

Problem Description

When installing ROCm on WSL using amdgpu-install, the installer asks for 24.6 GB of space, which seems excessive.

Operating System

Ubuntu 24.04 / WSL 2.6 / Windows 11 Pro 10.0.26200

CPU

AMD Ryzen 5 5600X

GPU

AMD Radeon RX 9060 XT

ROCm Version

6.4.2

ROCm Component

No response

Steps to Reproduce

On WSL, run the following:

wget https://repo.radeon.com/amdgpu-install/6.4.2.1/ubuntu/noble/amdgpu-install_6.4.60402-1_all.deb
sudo apt install ./amdgpu-install_6.4.60402-1_all.deb
amdgpu-install -y --usecase=wsl,rocm --no-dkms

After enumerating the required packages, the program will print the following:

Need to get 3923 MB/4193 MB of archives.
After this operation, 24.6 GB of additional disk space will be used.

(Optional for Linux users) Output of /opt/rocm/bin/rocminfo --support

No response

Additional Information

One ROCm developer suggested this is the result of bundling the code for all available platforms into a single installation.

This should be in the https://github.com/ROCm/ROCm/issues issues. You're specifying --no-dkms, which excludes amdgpu altogether. The amdgpu code is actually pretty small, all things considered (e.g. https://repo.radeon.com/amdgpu/31.10/ubuntu/pool/main/a/amdgpu-dkms/amdgpu-dkms_6.18.4.31100000-2286447.22.04_all.deb is only 12MB), but isn't included in WSL installs since amdgpu is just the kernel driver.
