I would like to discuss un-addressable device memory in the context of filesystem and block device. Specificaly how to handle write-back, read, ... when a filesystem page is migrated to device memory that CPU can not access. I intend to post a patchset leveraging the same idea as the existing block bounce helper (block/bounce.c) to handle this. I believe this is worth discussing during summit see how people feels about such plan and if they have better ideas. I also like to join discussions on: - Peer-to-Peer DMAs between PCIe devices - CDM coherent device memory - PMEM - overall mm discussions Cheers, Jérôme -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
