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

JG		 45/* Initialization path:
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)
