    This message showed up after an update today:

    * Messages for package virtual/opencl-3-r2:

    *
    * In order to take advantage of OpenCL you will need a runtime for your hardware.
    * Currently included in Gentoo are:
    *
    * * open:
    * - dev-libs/intel-compute-runtime - integrated Intel GPUs from Broadwell onwards. 64-bit only;
    * - dev-libs/pocl - to run OpenCL programs on your CPU, if you do not
    have a supported GPU;
    * - dev-libs/rocm-opencl-runtime - AMD GPUs supported by the amdgpu
    kernel driver. 64-bit only;
    * - media-libs/mesa[opencl] - some older AMD GPUs; see [1]. 32-bit support;
    *
    * * proprietary:
    * - dev-libs/amdgpu-pro-opencl - AMD Polaris GPUs. 32-bit support;
    * - dev-util/intel-ocl-sdk - Intel CPUs (*not* GPUs). 64-bit only;
    * - x11-drivers/nvidia-drivers[uvm] - Nvidia GPUs; specific package versions
    * required for older devices [2]. 32-bit support.

    On a number of stable systems with a selection of different Northern Islands
    to Sea Islands APUs/GPUs, I have media-libs/mesa installed in as a dependency. Given the above message and noticing dev-libs/rocm-opencl-runtime is still in testing, am I meant to keyword it and install it manually, or will it replace mesa automagically some day in the future when marked as stable?
