    drm/nouveau/mmu: support initialisation of client-managed address-spaces · 2606f291
    Ben Skeggs authored
    NVKM is currently responsible for managing the allocation of a client's
    GPU address-space, but there's various use-cases (ie. HMM address-space
    mirroring) where giving a client more direct control is desirable.
    
    This commit allows for a VMM to be created where the area allocated for
    NVKM is limited to a client-specified window, the remainder of address-
    space is controlled directly by the client.
    
    Leaving a window is necessary to support various internal requirements,
    but also to support existing allocation interfaces as not all of the HW
    is capable of working with a HMM allocation.
