cxl - 77-2+b1 main

This utility provides commands for enumerating and provisioning CXL devices.
CXL is a protocol that allows accessing memory over the PCI bus (PCIe ≥ 5)
with full cache coherency. The access can be in either direction, with
latencies closer to that of DDR (usually less than twice as bad) rather than
those usually associated with PCI attached storage.
.
This can be used eg. for installing many terabytes of memory into one
machine, dynamically sharing a pool of memory between machines in a rack,
letting a smart NIC use the host's memory on its own, letting a GPU access
both the host's memory and its own concurrently with the host, etc.
