    Iterate over physical engines · 305ebced
    Chris Wilson authored
    We current have a single for_each_engine() iterator which we use to
    generate both a set of uABI engines and a set of physical engines.
    Determining what uABI ring-id corresponds to an actual HW engine is
    tricky, so pull that out to a library function and introduce
    for_each_physical_engine() for cases where we want to issue requests
    once on each HW ring (avoiding aliasing issues).
    v2: Remember can_store_dword for gem_sync
    v3: Find more open-coded for_each_physical
