    Forgive my ignorance, but I thought there was plans to merge AMDGPU and AMDKFD into a single module?
    Was this plan abandoned or is it just too early to expect this merge?

          The two drivers are being built into a single module (ie merged from a build perspective) but are not being merged into a single driver.

          The amdgpu driver is a standard drm driver with one instance per GPU, while the amdkfd driver has one instance for the entire system and is built around a system-wide topology map.
