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