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. Major changes since V4: ================ - moved introduction of dlb in relnotes_20_11 to first patch in series - fixed underlines in dlb.rst that were too short - note that the code still uses its private byte-encoded versions of umonitor/umwait, rather than the new functions in the power patch that are built on top of those intrinsics. This is intentional. Changes since V3: ================ - updated MAINTAINERS file to alphabetically insert DLB - don't create RTE_ symbols in pmd - converted to use version.map scheme - converted to use .._master_lcore instead of .._main_lcore - this patch set is based on dpdk-next-eventdev Changes since V2: ================ - fixed meson conditional build. Moved test into driver’s meson.build file instead of event/meson.build - documentation is populated as associated code is introduced - add log_register in add dynamic logging patch - rename RTE_xxx symbol(s) as DLB2_xxx - replaced function ptr enqueue_four with direct call to movdir64b - remove unused port_pages - broke up probe patch into 3 smaller patches for easier review - changed param order of movdir64b/movntdq to match intrinsics - added self to MAINTAINERS files - squashed announcement of availability into last patch in series - correct spelling errors and delete repeated words - DPDK_21.0 -> DPDK 21 in map file - add experimental banner to public structs and APIs Changes since V1: ================= - implement changes requested in code reviews by Gage Eads and Mike Chen - fix a memzone leak - convert to use eal rte-cpuflags patch from Liang Ma Known Issues: - the documentation contained in dlb2.rst is not complete, and should be updated to include command line parameters (class of service, etc ...).
