Btw, there is another interesting thing around on the block:
NVMe Computational Storage devices. Don't be fooled by the name, much of it is not about neither computation not storage, but it allows to use the existing NVMe queuing model model to allow access to arbitrary accelerators, including a way to expose access to on-device memory.
The probably most current version is here:
https://www.snia.org/educational-library/nvme-computational-storage-update-standard-2022
The first version will be rather limited and miss some important functionality like directly accessing host DRAM or CXL integration, but much of that is planned. The initial version also probably won't be able to be supported by Linux at all, but we need to think hard about how to support it.
It woud also be really elpful to get more people with accelerator experience into the NVMe working group.
