支持 NVMe 持久内存区域 (PMR) 的 P2PDMA 是一种可能性,它可以加载存储访问并由某种持久数据(例如电池备份 RAM)支持,尽管他没有听说过任何正在开发的 NVMe PMR 驱动器。PMR 设备可能与以下用例重叠CXL,他说。 更好的 VM 和 IOMMU 支持正在开发中。PCIe 有多种处理和缓存内存地址转换的机制,可用于改进 P2PDMA...
做Peer to Peer DMA的PCIe Switch型号选型 Other Parts Discussed in Thread:TMUXHS4412 麻烦推荐一下带DMA的PCIe Switch型号。 upstream port接CPU 的PCIe Gen4 X16,2个downstream port:GPU( Gen4 X16),FPGA(Gen3 X8)
Peer-to-peer Direct Memory Access (DMA) permits the efficient transfer of data from one DMA capable Application Specific Integrated Circuit (ASIC) block to another without accessing memory. The peer-to-peer transfer can be done over a standard AMBA AHB bus architecture without side band signals ...
We created a number of textures in addition to the backbuffers, filled the textures with a peer to peer DMA then StretchRect into the backbuffer. This also exhibited the error seen in the image attached above. We have committed much time to this error, assistance is appreciated. Intel has ...
This is a Linux kernel mode driver that enables direct P2P communication between the memory of an Intel GPU card that supports the DMA-Buf framework and an HCA device that supports the PeerDirect interface from Mellanox.It provides two interfaces:As a Peer-Memory client: Peer-Memory is a ...

This builds upon earlier AMD Linux work likeP2P DMA between devices on AMD Zen systems. Now the last of the series is supporting the peer-to-peer import/export at the DMA-BUF level with this buffer sharing and synchronization framework being common among the Linux GPU drivers. ...

I believe P2PDMA is a nice step towards upstream support for PeerDirect, but I don't think it handles user-space access yet, which is needed for this use case. 😄 1 Sign up for free to join this conversation on GitHub. Already have an account? Sign in to comment ...
