  48  *  We expect that acceleration initialization might fail for various

  50  *  configurations. In order to still have a working userspace in such
  51  *  situation the init path must succeed up to the memory controller
  52  *  initialization point. Failure before this point are considered as
  53  *  fatal error. Here is the init callchain :
  54  *      radeon_device_init  perform common structure, mutex initialization
  55  *      asic_init           setup the GPU memory layout and perform all
  56  *                          one time initialization (failure in this
  57  *                          function are considered fatal)
  58  *      asic_startup        setup the GPU acceleration, in order to
  59  *                          follow guideline the first thing this
  60  *                          function should do is setting the GPU
  61  *                          memory controller (only MC setup failure
  62  *                          are considered as fatal)
