    Marks a path as failed when the path becomes faulty. Depending on the failback policy, it can reactivate the path. [5] Devmap-name: provides a meaningful device-name to udev for devmaps. [5] Kpartx: maps linear devmaps to device partitions to make multipath maps partitionable. [5] Multipath.conf: configuration file for the multipath daemon ...

    Examples of coherency protocols for cache memory are listed here. For simplicity, all "miss" Read and Write status transactions which obviously come from state "I" (or miss of Tag), in the diagrams are not shown. They are shown directly on the new state. Many of the following protocols have only historical value.

    A larger data path can be made by joining more than one data paths using multiplexers. A data path is the ALU, the set of registers, and the CPU's internal bus(es) that allow data to flow between them. [2] A microarchitecture data path organized around a single bus. The simplest design for a CPU uses one common internal bus.
