|

|
|
* - Vblank : look at Jesse's rework and what we should do

/* Initialization path:

|
|
* 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
|
|
