55  * DOC: IP Blocks
56  *
57  * GPUs are composed of IP (intellectual property) blocks. These
58  * IP blocks provide various functionalities: display, graphics,
59  * video decode, etc. The IP blocks that comprise a particular GPU
60  * are listed in the GPU's respective SoC file. amdgpu_device.c
61  * acquires the list of IP blocks for the GPU in use on initialization.
62  * It can then operate on this list to perform standard driver operations
63  * such as: init, fini, suspend, resume, etc.
64  *
65  *
66  * IP block implementations are named using the following convention:
67  * <functionality>_v<version> (E.g.: gfx_v6_0).
