1.Overview Command Processor(CP命令处理器)是一个可编程处理器,旨在为图形控制器设备提供一些片上智能。CP架构被视为一种特殊用途的计算引擎,针对获取和解释PROMO4(简称PM4)命令流,PM4是amdgpu的数据包格式。 CP命令处理器在一个典型的图形控制器中处理了几个任务: 作为接收器,接收来自在主机CPU上运行的视频和图形设备驱

The first block of the output shows the distance between the GPUs similar to what the numactl command outputs for the NUMA domains of a system. The weight is a qualitative measure for the “distance” data must travel to reach one GPU from another one. While the values do not carry a sp...
If the system is set to one NUMA domain per socket/processor (NPS1), bidirectional copy bandwidth between host memory and GPU memory may be slightly higher (up to about 16% more) than with four NUMA domains per socket processor (NPS4). For memory bandwidth sensitive applications using MPI,...
Graphic Command Processor:处理各种命令的处理器 Geometry Processor:几何处理 ACE:异步计算引擎 DMA:负责数据搬运的引擎 相比移动GPU,顶层一般都是一些硬化的模块,比如前端命令处理单元,负责分块处理的tiling模块,MMU单元等,近几年前端命令处理单元有逐渐软化的趋势,像Mali增加的CSF(Command Steam Frontend)就是个软化的...
The command processor sends work packages (i.e. workgroups of work-items in HIP) to the Compute Units (CUs) Blocks are executed in wavefronts (groups of 64 work-items on a SIMD) All wavefronts in a block reside on the same CU ...
Avoid vkCmdBlitImage() for Upscaling Up-scaling low-resolution frames using this command is inefficient, as it causes extra memory transfers. Optimized Code for Rendering Pipeline The following code demonstrates an optimized approach to implementing the rendering pipeline efficiently, minimizing memory ope...
Which processor do you use?I had the same issue. For me, the problem was the AMD PSP Device driver. Which is a chipset driver. Try to update this driver through the official AMD's webpage and make sure that it is updated. If the update doesn't help, try to disable this driver thr...
[Slides – 5.9MB PDF] GPU Work Graphs: Welcome to the future of GPU programming Matthäus Chajdas (AMD) and Shawn Hargreaves (Microsoft) We were thrilled to once again be invited to present at the Advanced Graphics Summit on the Monday. This year our topic was Work Graphs, which was re...
While I was able to get my PC mining, it has intermittently stopped working, not to mention I am doing everything over command line, which is difficult and time consuming for me. The past few days have been a struggle getting it to work. I appreciate the work you're doing on this. ...
