|
|
* GPUs are composed of IP (intellectual property) blocks. These
|
|
* IP blocks provide various functionalities: display, graphics,
|
|
* video decode, etc. The IP blocks that comprise a particular GPU
|
|
* are listed in the GPU's respective SoC file. amdgpu_device.c
|
|
* acquires the list of IP blocks for the GPU in use on initialization.
|
|
* It can then operate on this list to perform standard driver operations
|
|
* such as: init, fini, suspend, resume, etc.
|
|
*
|
|
*
|
|
* IP block implementations are named using the following convention:
|
|
* <functionality>_v<version> (E.g.: gfx_v6_0).
