The EAL PCI implementation is divided in two parts: - librte_pci: library offering helpers to handle PCI objects - librte_bus_pci: bus driver for PCI devices This allows other libraries / tools to use PCI elements (location, mappings, parsing operations, etc) without forcing a dependency on a bus driver. The latter should not have to export helpers that others might need. It is focused on defining the rte_pci_device, rte_pci_driver objects and their handling. The cryptodev library has hard dependencies on rte_pci_devices (used by generic probe function). Other similar libs (ether and eventdev) avoided the issue by inlining such functions and expecting users to include the relevant headers once the PCI bus has already been built. After review from Declan, he proposed to submit a patch removing this dependency. Once this patch is submitted, the relevant commit will be dropped from this patchset. v2: + Made rte_eal_using_phys_addrs common to both linux and bsd interfaces. + Added documentation of EAL API changes in release note. + Fixed a few rebase-related mistakes. + Fixed parallel build race condition reported by Luca Boccassi. + Grouped together commits breaking compilation: -> pci: introduce PCI lib and bus -> lib: include rte_bus_pci -> drivers: include rte_bus_pci -> test: include rte_bus_pci -> app/testpmd: include rte_bus_pci -> cryptodev: move PCI specific helpers to drivers/crypto Until all of them have been applied, compilation is broken. I am currently wondering whether merging some of them might be sensible. + Not included in this series: Several filesystem-related functions are currently private to the EAL and directly linked. This is not good, but the solution seems to be to have a new lib offering an FS abstraction. This seems an overreach for this patchset and should probably come in a second step. v3: + Fixed .map versioning + merged one commit breaking the build into the main commit moving code around. Other such commits are still present, as they only break specific subsystems (lib, drivers, apps, cryptodev). Merging them all within the one main commit does not seem right. As such, build is still broken from * pci: introduce PCI lib and bus until * cryptodev: move PCI specific helpers to drivers/crypto v4: + Rebased unto master, with new PCI functionalities integrated. + Removed the exposition of private EAL functions. While one commit did deal with this for one function, the issue is more widespread and should be fixed in a more generic way. + Introduced new PCI address parsing function, deprecating the old ones. + Fix conflict with bonding PMD regarding pci_addr_cmp function name. v5: + Rebase unto master: fix a few compilation issues with the header change. + Make more PCI bus functions private. ~*~ Compilation is still broken from * pci: introduce PCI lib and bus until * net/bonding: use local prefix for local function Gaetan Rivet (20): eal: include debug header in bus source ethdev: remove useless PCI dependency pci: introduce PCI lib and bus lib: include PCI bus header drivers: include PCI bus header test: include PCI bus header app/testpmd: include PCI bus header cryptodev: move PCI specific helpers to drivers/crypto net/bonding: use local prefix for local function pci: avoid inlining functions pci: avoid over-complicated macro pci: deprecate misnamed functions pci: introduce PCI address parsing function pci: make specialized parsing functions private bus/pci: use new PCI addr parsing function bus/pci: do not expose private functions bus/pci: do not expose PCI match function bus/pci: do not expose IOVA mode getter doc: add notes on EAL PCI API update bus: rename scan policy as probe policy app/test-pmd/testpmd.h | 1 + config/common_base | 10 + doc/guides/rel_notes/deprecation.rst | 10 + doc/guides/rel_notes/release_17_11.rst | 28 + drivers/bus/Makefile | 2 + drivers/bus/pci/Makefile | 59 ++ drivers/bus/pci/bsd/Makefile | 32 + drivers/bus/pci/bsd/pci.c | 681 +++++++++++++++++++ drivers/bus/pci/include/rte_bus_pci.h | 350 ++++++++++ drivers/bus/pci/linux/Makefile | 37 + drivers/bus/pci/linux/pci.c | 821 +++++++++++++++++++++++ drivers/bus/pci/linux/pci_init.h | 97 +++ drivers/bus/pci/linux/pci_uio.c | 568 ++++++++++++++++ drivers/bus/pci/linux/pci_vfio.c | 757 +++++++++++++++++++++ drivers/bus/pci/linux/vfio_mp_sync.c | 426 ++++++++++++ drivers/bus/pci/pci_common.c | 535 +++++++++++++++ drivers/bus/pci/pci_common_uio.c | 235 +++++++ drivers/bus/pci/private.h | 248 +++++++ drivers/bus/pci/rte_bus_pci_version.map | 17 + drivers/crypto/Makefile | 4 +- drivers/crypto/pci/Makefile | 52 ++ drivers/crypto/pci/rte_cryptodev_pci.c | 128 ++++ drivers/crypto/pci/rte_cryptodev_pci.h | 94 +++ drivers/crypto/pci/rte_cryptodev_pci_version.map | 7 + drivers/crypto/qat/qat_qp.c | 1 + drivers/event/octeontx/ssovf_probe.c | 1 + drivers/mempool/octeontx/octeontx_fpavf.c | 2 +- drivers/net/ark/ark_ethdev.c | 1 + drivers/net/avp/avp_ethdev.c | 2 + drivers/net/bnxt/bnxt.h | 1 + drivers/net/bonding/rte_eth_bond_args.c | 5 +- drivers/net/cxgbe/base/adapter.h | 1 + drivers/net/cxgbe/cxgbe_ethdev.c | 1 + drivers/net/e1000/em_ethdev.c | 1 + drivers/net/e1000/igb_ethdev.c | 1 + drivers/net/e1000/igb_pf.c | 1 + drivers/net/ena/ena_ethdev.h | 1 + drivers/net/enic/base/vnic_dev.h | 4 +- drivers/net/enic/enic_ethdev.c | 1 + drivers/net/enic/enic_main.c | 1 + drivers/net/i40e/i40e_ethdev.c | 1 + drivers/net/i40e/i40e_ethdev_vf.c | 1 + drivers/net/ixgbe/ixgbe_ethdev.c | 1 + drivers/net/ixgbe/ixgbe_ethdev.h | 1 + drivers/net/mlx4/mlx4_ethdev.c | 2 +- drivers/net/mlx5/mlx5.c | 1 + drivers/net/mlx5/mlx5_ethdev.c | 1 + drivers/net/nfp/nfp_nfpu.c | 2 +- drivers/net/nfp/nfp_nfpu.h | 2 +- drivers/net/octeontx/base/octeontx_pkivf.c | 2 +- drivers/net/octeontx/base/octeontx_pkovf.c | 2 +- drivers/net/sfc/sfc.h | 1 + drivers/net/sfc/sfc_ethdev.c | 1 + drivers/net/thunderx/nicvf_ethdev.c | 1 + drivers/net/virtio/virtio_ethdev.c | 1 + drivers/net/virtio/virtio_pci.h | 1 + drivers/net/vmxnet3/vmxnet3_ethdev.c | 1 + lib/Makefile | 2 + lib/librte_cryptodev/Makefile | 1 -
