The DLB2 PMD adds support for the Intel Dynamic Load Balancer 2.0 (DLB2) hardware. The DLB2 is a PCIe device that provides load-balanced, prioritized scheduling of core-to-core communication. The device consists of queues and arbiters that connect producer and consumer cores, and implements load-balanced queueing features including: - Lock-free multi-producer/multi-consumer operation. - Multiple priority levels for varying traffic types. - 'Direct' traffic (i.e. multi-producer/single-consumer) - Simple unordered load-balanced distribution. - Atomic lock-free load balancing across multiple consumers. - Queue element reordering feature allowing ordered load-balanced distribution. The DLB2 hardware supports both load balanced and directed ports and queues. Unlike other eventdev devices already in the repo, not all DLB2 ports and queues are equally capable. In particular, directed ports are limited to a single link, and must be connected to a directed queue. Additionally, even though LDB ports may link multiple queues, the number of queues that may be linked is limited by hardware. While reviewing the code, please be aware that this PMD has full control over the DLB2 hardware. Intel will be extending the DLB2 PMD in the future (not as part of this first series) with a mode that we refer to as the bifurcated PMD. The bifurcated PMD communicates with a kernel driver to configure the device, ports, and queues, and memory maps device MMIO so datapath operations occur purely in user-space. Note that the DLB2 hardware is a successor of the DLB hardware, and as such is structured similarly, both in terms of code layout and implementation. The framework to support both the PF PMD and bifurcated PMD exists in this patchset, and is why the iface.[ch] layer is present.
