The series includes shared header files, driver implementation, and changes to documentation files in support of this new driver. The AVP driver is a shared memory based device. It is intended to be used as a PMD within a virtual machine running on a Wind River virtualization platform. See: http://www.windriver.com/products/titanium-cloud/ It enables optimized packet throughput without requiring any packet processing in qemu. This allowed us to provide our customers with a significant performance increase for both DPDK and non-DPDK applications in the VM. Since our AVP implementation supports VM live-migration it is viewed as a better alternative to PCI passthrough or PCI SRIOV since neither of those support VM live-migration without manual intervention or significant performance penalties. Since the initial implementation of AVP devices, vhost-user has become part of the qemu offering with a significant performance increase over the original virtio implementation. However, vhost-user still does not achieve the level of performance that the AVP device can provide to our customers for DPDK based guests. A number of our customers have requested that we upstream the driver to dpdk.org. v2: * Fixed coding style violations that slipped in accidentally because of an out of date checkpatch.pl from an older kernel. v3: * Updated 17.05 release notes to add a section for this new PMD * Added additional info to the AVP nic guide document to clarify the benefit of using AVP over virtio. * Fixed spelling error in debug log missed by local checkpatch.pl version * Split the transmit patch to separate the stats functions as they accidentally got squashed in the last patchset. * Fixed debug log strings so that they exceed 80 characters rather than span multiple lines. * Renamed RTE_AVP_* defines that were in avp_ethdev.h to be AVP_* instead * Replaced usage of RTE_WRITE32 and RTE_READ32 with rte_write32_relaxed and rte_read32_relaxed. * Declared rte_pci_id table as const v4: * Split our interrupt handlers to a separate patch and moved to the end of the series. * Removed memset() from stats_get API * Removed usage of RTE_AVP_ALIGNMENT * Removed unnecessary parentheses in rte_avp_common.h * Removed unneeded "goto unlock" where there are no statements in between the goto and the end of the function. * Re-tested with pktgen and found that rte_eth_tx_burst() is being called with 0 packets even before starting traffic which resulted in incrementing oerrors; fixed in transmit patch. v5: * Updated documentation to remove references to ivshmem as it lead to confusion about whether AVP is exactly like ivshmem or simply based on how ivshmem exports memory to a VM via a PCI device. * Restructured first set of patches to condense them down to a base patch with the files needed to apply subsequent patches. * Removed static prototypes from init/uninit functions in avp_ethdev.c * Moved MAC addresses init to the device initialization patch because it is setup by the avp_dev_create() function. * Split the changes to the avp.ini features file so that features are marked as enabled in the patch that actually enables them.
