|
|
* - 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.
|

|

/* 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)

* When there is not enough room at the end, we start waiting for
