Some of the protocols support syncing via the protocol like, EFI_FILE_PROTOCOL.Flush(). Disconnect also does a sync for that part of the device tree. >>> >>> Also in general, what is the difference between a "ControllerHandle" and a >>> "DriverHandle" in terms of getting handles. The DriverHandle is the handle associated with the device driver, and it contains the EFI Loaded Image Protocol. See chapter 12 UEFI 2.4. >>> In other words, If I have a block io protocol handle is that a controller >>> handle or a driver handle or some other handle?

From a bus driver point of view you just copy your parents device path and append a node that represents what your driver manages. So for example the partition driver is adding the HD(1,GPT,E223FF7F-F2DA-4DBB-B765-756F2D95B0FE,0x28,0x64000) node, but it just copies PcieRoot(0x0)/Pci(0x1F,0x2)/Sata(0x0,0x0,0x0) and does not need to understand anything about that path.
