This series hides them, and mark associated driver only API as internal. A good amount of the patches are preparation work on rte_bus.h, rte_dev.h, rte_devargs.h and rte_eal.h headers, removing dependencies between them. PCI bus specific handling are removed from testpmd, unit tests and examples. After this series, driver-only API headers for registering to buses are not exported anymore, unless the enable_driver_sdk meson option is selected. New accessors for rte_bus, rte_driver and rte_device have been added, marked with an experimental tag first when introducing them, and later in the series marked as stable since external users will want to use those drop-in replacements right away. A check is added to ensure we won't pollute app/ and examples/ again, though some unit tests are left intentionnally untouched as they test some internals of DPDK. Changes since v4: - (hopefully, because I can't test) fixed Windows build, - dropped unneeded change in vdev unit test, Changes since RFC v3: - marked the series as non-RFC, - rebased on v22.11-rc0, - marked RTE_FUNC_PTR_* macros as deprecated, - split the bus specific patch in two patches, Changes since RFC v2: - added check for additions of include .*_(driver|pmd)\.h in apps and examples, - dropped legacy/debug testpmd commands to read PCI BAR0 registers, - dropped patches on bbdev, ethdev, rawdev driver headers for now, - reordered patches and separated changes per bus type to ease review, - added more accessor for device, - introduced rte_dev_bus_info to provide a Bus specific description of a device, a first use is for providing a PCI device vendor / device identifiers that are otherwise unavailable through a generic existing API, Changes since RFC v1: - added two more cleanups (new patch 3 and 4) for unit test and examples relying on PCI specific info, - went on with masking rte_driver and rte_device too,
