32 * - surface allocator & initializer : (bit like scratch reg) should
33 * initialize HDP_ stuff on RS600, R600, R700 hw, well anythings
34 * related to surface
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
38 * - cs : clean cs ioctl use bitmap & things like that.
39 * - power management stuff
40 * - Barrier in gart code
41 * - Unmappabled vram ?
42 * - TESTING, TESTING, TESTING

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)

523 * locking.
524 *
525 * Principe is simple, we keep a list of sub allocation in offset
526 * order (first entry has offset == 0, last entry has the highest
527 * offset).
528 *
529 * When allocating new object we first check if there is room at
530 * the end total_size - (last_object_offset + last_object_size) >=
531 * alloc_size. If so we allocate new object there.
532 *
533 * When there is not enough room at the end, we start waiting for
534 * each sub object until we reach object_offset+object_size >=
535 * alloc_size, this object then become the sub object we return.
536 *
537 * Alignment can't be bigger than page size.
538 *
539 * Hole are not considered for allocation to keep things simple.
540 * Assumption is that there won't be hole (all object on same
541 * alignment).
