34 /* TODO: Here are things that needs to be done :
35 * - surface allocator & initializer : (bit like scratch reg) should
36 * initialize HDP_ stuff on RS600, R600, R700 hw, well anythings
38 * - WB : write back stuff (do it bit like scratch reg things)
39 * - Vblank : look at Jesse's rework and what we should do
40 * - r600/r700: gart & cp
41 * - cs : clean cs ioctl use bitmap & things like that.
42 * - power management stuff
43 * - Barrier in gart code
44 * - Unmappabled vram ?
45 * - TESTING, TESTING, TESTING
48 /* Initialization path:
49 * We expect that acceleration initialization might fail for various
50 * reasons even thought we work hard to make it works on most
51 * configurations. In order to still have a working userspace in such
52 * situation the init path must succeed up to the memory controller
53 * initialization point. Failure before this point are considered as
54 * fatal error. Here is the init callchain :
55 * radeon_device_init perform common structure, mutex initialization
56 * asic_init setup the GPU memory layout and perform all
57 * one time initialization (failure in this
58 * function are considered fatal)
59 * asic_startup setup the GPU acceleration, in order to
60 * follow guideline the first thing this
61 * function should do is setting the GPU
62 * memory controller (only MC setup failure
63 * are considered as fatal)
