    "content": "This patchset introduces a new EAL API for querying devices,\nfiltered by arbitrary properties.\n\nThe following elements are introduced to this end:\n\n * A new object, \"rte_class\", is used to describe\n   the device class abstraction layer (eth, crypto, ...).\n\n * Both rte_bus and rte_class now offer a way to\n   list their devices and filter the result\n   using locally defined properties.\n\n * The rte_dev API now has an rte_dev_iterator, which\n   is the way for the user to define the device filter\n   and iterate upon the resulting set.\n\nAs an example, the \"eth\" device class is implemented.\n\nAdditionally, the device filters for\n\n  + rte_bus_pci\n  + rte_bus_vdev\n  + rte_class_eth\n\nare implemented and can be used with some\nproperties each, to show how to extend those.\n\nSome example of filters:\n\n  \"bus=pci/class=eth\"\n  \"bus=pci\"\n  \"class=eth\"\n  \"class=eth,name=net_ring0\"\n  \"bus=pci,id=00:00.0\"\n  \"bus=vdev,driver=net_ring\"\n\n---\n\nv2:\n\n  * Reworked the dev_iterate callback to simplify\n    its implementation.\n\n    Now dev_iterate implementation do not need to learn\n    about the intricacies of the rte_dev_iterator.\n    The rte_dev_iterator is managed purely by the\n    rte_dev_iterator_next function. Buses and classes then\n    do not have to care about settings things right.\n\n    Additionally, dev_iterate implementations do not\n    have to sanitize their dev string anymore, they\n    are prepared by the rte_dev layer prior, which also\n    reduces the number of dynamic allocations.\n\nv3:\n\n  * Introduced central constructor priority list.\n  * Removed lightweight kvarg parsing utility,\n    using librte_kvargs instead.\n  * Reversed dependencies of librte_kvargs and\n    librte_eal.\n  * Fixed a few bugs.\n  * @Bruce: I have noted the request for meson support.\n    I will install it and attempt it once the bulk of the work is done.\n\nv4:\n\n  * Fixed a few bugs, added relevant acks,\n    fixed some typos.\n  * Made each matching functions actually check for a proper\n    list of accepted properties.\n  * rte_kvargs now includes rte_eal directly and keeps rte_log.\n  * added generic string comparison function to rte_kvargs,\n    as some kind of comparison should probably be shared by many layers.\n\nv5:\n\n  * Rebased on master\n  * Use strcspn instead of custom function.\n  * Introduce private generic rte_eth_dev iterator.\n    This could be generalized to other iterators\n    (port_next, owner_id-aware, etc).\n  * Attempted to support meson.build.\n    Got lost in the implicit variables declared\n    when inversing dependencies between kvargs and EAL.\n    Removed anything related to meson.\n  * Postponed genericization of work from\n    device query to device declaration.\n    Much bigger than anticipated, will let this\n    part get in first and iterate over it.\n\nv6:\n\n  * Rebased on master\n  * Introduce RTE_PRIORITY_LAST, to explicitly set\n    the lowest constructor priority.\n  * Fix copyright notice for eth_privage.* files.\n\nv7:\n\n  * Rebased on master\n  * Fix rte_kvargs_strcmp return value.\n  * Fix layer parsing error\n    devstr \"bus=pci/onemorelayer\" now tells\n    that the additional layer is not recognized.\n\nv8:\n\n  * Rebased on master\n  * Cleaned kvargs use: introduced\n    a new parser function, that simplifies\n    using the library for DPDK devargs.\n  * Refactored devargs parsing in a single\n    function within rte_devargs.\n    This function is useful both for rte_dev\n    parsing its iterator, and for rte_devargs\n    parsing --dev parameters (not yet implemented).\n  * A few small bugfixes.\n\nv9:\n\n  * Rebased on master\n  * Fixed cyclic dependency kvargs <-> eal\n  * Fixed a few checkpatch issues\n  * Added dynamic help to testpmd for new \"show device\" command\n  * Added devargs processing stubs to\n    primary buses / classes\n  * Added new --dev generic device declaration option\n\nv10:\n\n  * Support meson build\n\nGaetan Rivet (27):\n  devargs: add non-variadic parsing function\n  kvargs: remove error logs\n  kvargs: build before EAL\n  kvargs: introduce a more flexible parsing function\n  eal: introduce dtor macros\n  eal: introduce device class abstraction\n  eal/class: register destructor\n  devargs: add function to parse device layers\n  eal/dev: add device iterator interface\n  eal/class: add device iteration\n  eal/bus: add device iteration\n  eal/dev: implement device iteration initialization\n  eal/dev: implement device iteration\n  kvargs: add generic string matching callback\n  bus/pci: implement device iteration and comparison\n  bus/pci: add device matching field id\n  bus/vdev: implement device iteration\n  bus/vdev: add device matching field driver\n  ethdev: add private generic device iterator\n  ethdev: register ether layer as a class\n  ethdev: add device matching field name\n  app/testpmd: add show device command\n  bus/pci: pre-process declarative PCI devargs\n  bus/vdev: pre-process declarative vdev devargs\n  bus/pci: process declarative PCI devargs\n  ethdev: process declarative eth devargs\n  eal: add generic dev parameter\n\n app/test-pmd/cmdline.c                      |  54 +++++\n
