Gentoo OpenCL drivers without GPU (so CPU-only)

I have access to a new university machine which runs 4x AMD® Opteron™  6212 processors, but has no separate GPU. And now I'd need to get OpenCL working here. The machine runs Gentoo linux, this may be a bit of an unhappy choice but I have no say in that.

I wonder how find and install the proper OpenCL drivers. I can find drivers for the AMD GPUs, but there is no separate GPU, so that's probably not the best idea. I can find drivers for the Intel CPUs, but they are AMD CPUs. I can find windows-only drivers with auto-detect, so which work for just the CPU, but they are windows-only and I run Gentoo linux.

So how should I find and install the drivers to actually run my programs on this new machine?

Problem solved: somewhere deeply hidden, I found a package x11-drivers/ati-drivers.

So running "emerge x11-drivers/ati-drivers" solved the problem. Now clinfo() runs correctly. 🙂
