The DLB\n PMD adds support for the Intel Dynamic Load Balancer (DLB) hardware.\n The DLB is a PCIe device that provides load-balanced, prioritized\n scheduling of core-to-core communication. The device consists of\n queues and arbiters that connect producer and consumer cores, and\n implements load-balanced queueing features including:\n - Lock-free multi-producer/multi-consumer operation.\n - Multiple priority levels for varying traffic types.\n - 'Direct' traffic (i.e. multi-producer/single-consumer)\n - Simple unordered load-balanced distribution.\n - Atomic lock-free load balancing across multiple consumers.\n - Queue element reordering feature allowing ordered load-balanced\n distribution.\n \n The DLB hardware supports both load balanced and directed ports and\n queues. Unlike other eventdev devices already in the repo, not all\n DLB ports and queues are equally capable. In particular, directed\n ports are limited to a single link, and must be connected to a directed\n queue.\n Additionally, even though LDB ports may link multiple queues, the\n number of queues that may be linked is limited by hardware. Another\n difference is that DLB does not have a straightforward way of carrying\n the flow_id in the queue elements (QE) that the hardware operates on.\n \n Due to the above restrictions, we would like to extend the eventdev\n interface in manner that allows our PMD to take full advantage of\n the DLB hardware, while also adding useful functionality for non-Intel\n PMDs. Our proposed changes are contained in the first two patches\n in this patchset.\n \n While reviewing the code, please be aware that this PMD has full\n control over the DLB hardware. Intel will be extending the DLB PMD\n in the future (not as part of this first series) with a mode that we\n refer to as the bifurcated PMD. The bifurcated PMD communicates with a\n kernel driver to configure the device, ports, and queues, and memory\n maps device MMIO so datapath operations occur purely in user-space.\n \n The framework to support both the PF PMD and bifurcated PMD exists in\n this patchset, and is why the iface.[ch] layer is present.\n \n Thank You and Best Regards,\n \n Tim McDaniel\n\n\nMcDaniel, Timothy (27):\n
