VFIO is a kernel 3.6+ driver allowing secure DMA from userspace by means of using IOMMU instead of working directly with physical memory like igb_uio does. Short summary: * Adding support for VFIO in EAL PCI code * Adding new command-line parameter for VFIO interrupt type * Adding support for VFIO in setup.sh * Renaming igb_uio_bind to dpdk_nic_bind and adding support for VFIO there * Removing PCI ID list from igb_uio, effectively making it another generic PCI driver similar to pci_stub, vfio-pci et al * Adding autotest for VFIO interrupt types * Making igb_uio and VFIO compilation optional I'm submitting this as an RFC because this patch is based off current dpdk.org branch with David Marchand's RTE_EAL_UNBIND_PORTS patchset. IOW, this will *not* apply to the dpdk.org tree *unless* you also apply David's patches beforehand. Signed-off by: Anatoly Burakov Anatoly Burakov (16): Separate igb_uio mapping into a separate file Distinguish between legitimate failures and non-fatal errors Rename RTE_PCI_DRV_NEED_IGB_UIO to RTE_PCI_DRV_NEED_MAPPING Make igb_uio compilation optional Moved interrupt type out of igb_uio Add support for VFIO in Linuxapp targets Add support for VFIO interrupts, add VFIO header Add support for mapping devices through VFIO. Enable VFIO device binding Added support for selecting VFIO interrupt type from EAL command-line Make --no-huge use mmap instead of malloc. Adding unit tests for VFIO EAL command-line parameter Removed PCI ID table from igb_uio Renamed igb_uio_bind to dpdk_nic_bind Added support for VFIO drivers in dpdk_nic_bind.py Adding support for VFIO to setup.sh app/test/test_eal_flags.c | 24 + app/test/test_pci.c | 4 +- config/defconfig_i686-default-linuxapp-gcc | 2 + config/defconfig_i686-default-linuxapp-icc | 2 + config/defconfig_x86_64-default-linuxapp-gcc | 2 + config/defconfig_x86_64-default-linuxapp-icc | 2 + lib/librte_eal/bsdapp/eal/eal_pci.c | 2 +- lib/librte_eal/common/Makefile | 1 + lib/librte_eal/common/eal_common_pci.c | 17 +- lib/librte_eal/common/include/rte_pci.h | 7 +- .../common/include/rte_pci_dev_feature_defs.h | 46 ++ .../common/include/rte_pci_dev_features.h | 42 ++ lib/librte_eal/linuxapp/Makefile | 2 + lib/librte_eal/linuxapp/eal/Makefile | 6 +- lib/librte_eal/linuxapp/eal/eal.c | 35 + lib/librte_eal/linuxapp/eal/eal_interrupts.c | 203 +++++- lib/librte_eal/linuxapp/eal/eal_memory.c | 8 +- lib/librte_eal/linuxapp/eal/eal_pci.c | 480 ++------------ lib/librte_eal/linuxapp/eal/eal_pci_uio.c | 416 ++++++++++++ lib/librte_eal/linuxapp/eal/eal_pci_vfio.c | 709 +++++++++++++++++= ++++ lib/librte_eal/linuxapp/eal/eal_pci_vfio_socket.c | 367 +++++++++++ .../linuxapp/eal/include/eal_internal_cfg.h | 3 + lib/librte_eal/linuxapp/eal/include/eal_pci_init.h | 120 ++++ lib/librte_eal/linuxapp/eal/include/eal_vfio.h | 55 ++ .../linuxapp/eal/include/exec-env/rte_interrupts.h | 7 +- lib/librte_eal/linuxapp/igb_uio/igb_uio.c | 70 +- lib/librte_pmd_e1000/em_ethdev.c | 2 +- lib/librte_pmd_e1000/igb_ethdev.c | 4 +- lib/librte_pmd_ixgbe/ixgbe_ethdev.c | 4 +- lib/librte_pmd_vmxnet3/vmxnet3_ethdev.c | 2 +- tools/dpdk_nic_bind.py | 500 +++++++++++++++ tools/igb_uio_bind.py | 485 -------------- tools/setup.sh | 168 ++++- 33 files changed, 2797 insertions(+), 1000 deletions(-) create mode 100644 lib/librte_eal/common/include/rte_pci_dev_feature_defs.= h create mode 100644 lib/librte_eal/common/include/rte_pci_dev_features.h create mode 100644 lib/librte_eal/linuxapp/eal/eal_pci_uio.c create mode 100644 lib/librte_eal/linuxapp/eal/eal_pci_vfio.c create mode 100644 lib/librte_eal/linuxapp/eal/eal_pci_vfio_socket.c create mode 100644 lib/librte_eal/linuxapp/eal/include/eal_pci_init.h create mode 100644 lib/librte_eal/linuxapp/eal/include/eal_vfio.h create mode 100755 tools/dpdk_nic_bind.py delete mode 100755 tools/igb_uio_bind.py --=20 1.8.1.4
