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)
