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. On Wednesday C...
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 ...
