  35  *      - WB : write back stuff (do it bit like scratch reg things)
  36  *      - Vblank : look at Jesse's rework and what we should do
  37  *      - r600/r700: gart & cp

  40  *      - Barrier in gart code

  46  *  We expect that acceleration initialization might fail for various
  47  *  reasons even thought we work hard to make it works on most
  48  *  configurations. In order to still have a working userspace in such
  49  *  situation the init path must succeed up to the memory controller
  50  *  initialization point. Failure before this point are considered as
  51  *  fatal error. Here is the init callchain :
  52  *      radeon_device_init  perform common structure, mutex initialization
  53  *      asic_init           setup the GPU memory layout and perform all
  54  *                          one time initialization (failure in this
  55  *                          function are considered fatal)
  56  *      asic_startup        setup the GPU acceleration, in order to
  57  *                          follow guideline the first thing this
  58  *                          function should do is setting the GPU
  59  *                          memory controller (only MC setup failure
  60  *                          are considered as fatal)
