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

56 * asic_startup setup the GPU acceleration, in order to
57 * follow guideline the first thing this
