I've successfully installed Ubuntu 18.04 as described in https://www.udoo.org/docs-bolt/Operating_Systems/Linux/Known_issues.html and installed ROCm packages provided for Ubuntu by AMD. However I was unable to get ROCm to work properly (basic ROCm applications such as "rocminfo" or "clinfo" fail to run). After some investigation in system logs I strongly suspect the issue is in initialization of "amdkfd" driver (which is one of kernel space components of ROCm) which fails due to lack of "IOMMUv2" support. So I tried to find "IOMMUv2" in BIOS (or any IOMMU for that matter) and it seems that the option is missing (I believe the CPU indeed does support IOMMUv2). Is it possible to expose IOMMUv2 in BIOS? Or is there any other way to get ROCm to work without it?
