It's basically a 1:1 move of the functionality from DRM to DMA-buf. For my big picture understanding, and because I spotted in the latest rocm release that apparently the fancy interconnect is now support. I looked around a bit in upstream and basic xgmi support seems to be there already, but I haven't seen anything that looks like xgmi buffer sharing is there already? Missing something, or am I looking at the wrong thing (xgmi seems to be the engineering name for that fancy interconnect at least). For the big plan I've seen the dynamic dma-buf and p2p stuff, I think it'd be good if we also make sure xgmi and related things integrate somewhat neatly. Ofc xgmi requires that we upcast the dma_buf_attachment to somethign driver specific (I don't think we should make that generic, but maybe Jerome has different ideas with HMM). Question I have is how much of the map/unmap/invaliidate and passing sg tables around we can reuse for this. If you have patches/pointers would be really intersting to read them a bit. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
