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

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