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

527 * locking.
528 *
529 * Principe is simple, we keep a list of sub allocation in offset
530 * order (first entry has offset == 0, last entry has the highest
531 * offset).
532 *
533 * When allocating new object we first check if there is room at
534 * the end total_size - (last_object_offset + last_object_size) >=
535 * alloc_size. If so we allocate new object there.
536 *
537 * When there is not enough room at the end, we start waiting for
538 * each sub object until we reach object_offset+object_size >=
539 * alloc_size, this object then become the sub object we return.
540 *
541 * Alignment can't be bigger than page size.
542 *
543 * Hole are not considered for allocation to keep things simple.
544 * Assumption is that there won't be hole (all object on same
545 * alignment).
