    drm/amdgpu: Add H/W agnostic amdgpu <--> amdkfd interface · 130e0371
    Oded Gabbay authored
    This patch adds an interface file between amdgpu and amdkfd. This
    interface file is H/W agnostic, thus containing functions that
    operate the same for any AMD APU/GPU H/W generation.
    
    The functions in this interface mirror (some) of the functions in
    radeon_kfd.c (the radeon<-->amdkfd interface file). The main functions
    are:
    
    - amdgpu_amdkfd_init - initialize the amdkfd module
    - amdgpu_amdkfd_load_interface - load the H/W interface according to the
      currently probed device
    - amdgpu_amdkfd_device_probe - probe the device in amdkfd
    - amdgpu_amdkfd_device_init - initialize the device in amdkfd
    - amdgpu_amdkfd_interrupt - call the ISR of amdkfd
    - amdgpu_amdkfd_suspend - suspend callback from amdgpu
    - amdgpu_amdkfd_resume - resume callback from amdgpu
    
    This patch also modifies the relevant amdgpu files, to use this new
    interface.
