From: David Marchand <david.march...@6wind.com> * Original patch series is from David Marchand. This is just a rebase over master (d76c19309) *
Following discussions with Jan [1] and some cleanup I started on pci code, here is a patchset that reworks pdev drivers registration and hotplug api. The structures changes mentioned in [1] are still to be done, but at least, I think we are one step closer to it. Before this patchset, rte_driver .init semantics differed whether it concerned a pdev or a vdev driver: - for vdev, it actually meant that a devargs is given to the driver so that it creates ethdev / crypto objects, so it was a probing action - for pdev, it only registered the driver triggering no ethdev / crypto objects >From my pov, eal hotplug api introduced in this patchset still needs more work so that it does not need to know about devargs. So a new devargs api is needed. Changes since v2: - rebase over HEAD (d76c193) - Move SYSFS_PCI_DRIVERS macro to rte_pci.h to avoid compilation issue Changes since v1: - rebased on HEAD, new drivers should be okay - patches have been split into smaller pieces - RTE_INIT macro has been added, but in the end, I am not sure it is useful - device type has been removed from ethdev, as it was used only by hotplug - getting rid of pmd type in eal patch (patch 5 of initial series) has been dropped for now, we can do this once vdev drivers have been converted [1] http://dpdk.org/ml/archives/dev/2016-January/031390.html David Marchand (17): pci: no need for dynamic tailq init crypto: no need for a crypto pmd type drivers: align pci driver definitions eal: remove duplicate function declaration eal: introduce init macros crypto: export init/uninit common wrappers for pci drivers ethdev: export init/uninit common wrappers for pci drivers drivers: convert all pdev drivers as pci drivers crypto: get rid of crypto driver register callback ethdev: get rid of eth driver register callback eal/linux: move back interrupt thread init before setting affinity pci: add a helper for device name pci: add a helper to update a device ethdev: do not scan all pci devices on attach eal: add hotplug operations for pci and vdev ethdev: convert to eal hotplug ethdev: get rid of device type app/test/virtual_pmd.c | 2 +- drivers/crypto/qat/rte_qat_cryptodev.c | 18 +- drivers/net/af_packet/rte_eth_af_packet.c | 2 +- drivers/net/bnx2x/bnx2x_ethdev.c | 35 +-- drivers/net/bonding/rte_eth_bond_api.c | 2 +- drivers/net/cxgbe/cxgbe_ethdev.c | 24 +- drivers/net/cxgbe/cxgbe_main.c | 2 +- drivers/net/e1000/em_ethdev.c | 16 +- drivers/net/e1000/igb_ethdev.c | 40 +-- drivers/net/ena/ena_ethdev.c | 20 +- drivers/net/enic/enic_ethdev.c | 23 +- drivers/net/fm10k/fm10k_ethdev.c | 23 +- drivers/net/i40e/i40e_ethdev.c | 26 +- drivers/net/i40e/i40e_ethdev_vf.c | 25 +- drivers/net/ixgbe/ixgbe_ethdev.c | 47 +--- drivers/net/mlx4/mlx4.c | 22 +- drivers/net/mlx5/mlx5.c | 21 +- drivers/net/mpipe/mpipe_tilegx.c | 2 +- drivers/net/nfp/nfp_net.c | 23 +- drivers/net/null/rte_eth_null.c | 2 +- drivers/net/pcap/rte_eth_pcap.c | 2 +- drivers/net/ring/rte_eth_ring.c | 2 +- drivers/net/szedata2/rte_eth_szedata2.c | 25 +- drivers/net/vhost/rte_eth_vhost.c | 2 +- drivers/net/virtio/virtio_ethdev.c | 26 +- drivers/net/vmxnet3/vmxnet3_ethdev.c | 23 +- drivers/net/xenvirt/rte_eth_xenvirt.c | 2 +- examples/ip_pipeline/init.c | 22 -- lib/librte_cryptodev/rte_cryptodev.c | 67 +---- lib/librte_cryptodev/rte_cryptodev.h | 2 - lib/librte_cryptodev/rte_cryptodev_pmd.h | 45 +--- lib/librte_cryptodev/rte_cryptodev_version.map | 9 +- lib/librte_eal/bsdapp/eal/eal_pci.c | 52 +++- lib/librte_eal/bsdapp/eal/rte_eal_version.map | 2 + lib/librte_eal/common/eal_common_dev.c | 39 +++ lib/librte_eal/common/eal_common_pci.c | 19 +- lib/librte_eal/common/eal_private.h | 20 +- lib/librte_eal/common/include/rte_dev.h | 29 ++- lib/librte_eal/common/include/rte_eal.h | 3 + lib/librte_eal/common/include/rte_pci.h | 35 +++ lib/librte_eal/common/include/rte_tailq.h | 4 +- lib/librte_eal/linuxapp/eal/eal.c | 7 +- lib/librte_eal/linuxapp/eal/eal_pci.c | 16 +- lib/librte_eal/linuxapp/eal/rte_eal_version.map | 2 + lib/librte_ether/rte_ethdev.c | 315 ++++-------------------- lib/librte_ether/rte_ethdev.h | 40 ++- lib/librte_ether/rte_ether_version.map | 9 +- 47 files changed, 383 insertions(+), 811 deletions(-) -- 2.7.4
