We tried to standardize exactly this - eBPF programs offloaded onto the device. The NVMe standard now has a lot of infrastructure for this standardized, including commands to discover device memory topology, transfer to/from that memory, and discover and upload programs. But one of the blockers is that eBPF isn't itself standardized. The other blockers are vendors ready and willing to build these devices and customers ready to buy them in volume. The extra compute ability will introduce some extra cost.
I'm still hopeful that we see it happen some day.
