We are trying to make a peer-to- peer transaction between 2 End-Points, through Intel chipset without succession. (Not through CPU/ CPU memory). The 2 E.P. connected to PCIe channels of the QM57 \ QM77 \ QM170. There is communication between the EP and the CPU/CPU memory. but not...
Peer-to-peer 两台PCI设备之间直接传送数据;PCI总线系统中的主机身份并不是固定不变的,而是可以切换的(借助仲裁器),但是同一时刻只能存在一个主机。 完成Peer-to-Peer这一传输方式的前提是,PCI总线系统中至少存在一个有能力成为主机的设备。在仲裁器的控制下,完成主机身份的切换,进而获得PCI总线的控制权, 然后与总...
PCIe peer-to-peer communication (P2P) is a PCIe feature which enables two PCIe devices to directly transfer data between each other without using host RAM as a temporary storage. However, there are a number of issues that make P2P transactions tricky to do in a perfectly safe way. ...

1 : GPU Frame Buffer BAR – In this example it happens to be 256M, but typically this will be size of the GPU memory (typically 4GB+). This BAR has to be placed < 2^40 to allow peer-to-peer access from other GFX8 AMD GPUs. For GFX9 (Vega GPU) the BAR has to be placed <...
