5 Here you can find some generic acronyms used in the amdgpu driver. Notice that
6 we have a dedicated glossary for Display Core at

12 The number of CUs that are active on the system. The number of active
13 CUs may be less than SE * SH * CU depending on the board configuration.
19 Content Protection Library

28 Enhanced Content Protection
34 Graphics Address Remapping Table. This is the name we use for the GPUVM
35 page table used by the GPU kernel driver. It remaps system resources
36 (memory or MMIO space) into the GPU's address space so the GPU can access
37 them. The name GART harkens back to the days of AGP when the platform
38 provided an MMU that the GPU could use to get a contiguous view of
39 scattered pages for DMA. The MMU has since moved on to the GPU, but the
46 Graphic Memory Controller
49 GPU Virtual Memory. This is the GPU's MMU. The GPU supports multiple
50 virtual address spaces that can be in flight at any given time. These
51 allow the GPU to remap VRAM and system resources into GPU virtual address
52 spaces for use by the GPU kernel driver and applications using the GPU.
53 These provide memory protection for different applications using the GPU.
56 Graphics Translation Tables. This is a memory pool managed through TTM
57 which provides access to system resources (memory or MMIO space) for
58 use by the GPU. These addresses can be mapped into the "GART" GPUVM page
59 table for use by the kernel driver or into per process GPUVM page tables
60 for application usage.
