34 * - surface allocator & initializer : (bit like scratch reg) should
35 * initialize HDP_ stuff on RS600, R600, R700 hw, well anythings
36 * related to surface
37 * - WB : write back stuff (do it bit like scratch reg things)
38 * - Vblank : look at Jesse's rework and what we should do
39 * - r600/r700: gart & cp
40 * - cs : clean cs ioctl use bitmap & things like that.
41 * - power management stuff
42 * - Barrier in gart code
43 * - Unmappabled vram ?

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