These library changes provide a new Intel DPDK feature for communicating with virtual machines using QEMU's IVSHMEM mechanism. The feature works by providing a command line for QEMU to map several hugepages into a single IVSHMEM device. For the guest to know what is inside any given IVSHMEM device (and to distinguish between Intel(R) DPDK and non-Intel(R) DPDK IVSHMEM devices), a metadata file is also mapped into the IVSHMEM segment. No work needs to be done by the guest application to map IVSHMEM devices into memory; they are automatically recognized by the Intel(R) DPDK Environment Abstraction Layer (EAL). Changes in this patch: * Changes to EAL to allow mapping of all hugepages in a memseg into a single file * Changes to EAL to allow ivshmem devices to be transparently mapped in the process running on the guest. * New ivshmem library to create and manage metadata exported to guest VM's * New ivshmem compilation targets * Mempool and ring changes to allow export of structures to a VM and allow a VM to attach to those structures. * New autotests to unit tests this functionality.
