When SR-IOV virtual functions devices are enabled a corresponding representor port for each VF can be enabled in the process in which the i40e PMD is running within, by specifying the representor devarg with the list of VF ports that representors are to be created for. An example of the devargs which would create VF representor for virtual functions 0,2,4,5,6 and 7 is: -w pci:D:B:D.F,representor=[0,2,4-7] Signed-off-by: Declan Doherty Signed-off-by: Mohammad Abdul Awal Signed-off-by: Remy Horton --- drivers/net/i40e/Makefile | 3 + drivers/net/i40e/i40e_ethdev.c | 71 +++++- drivers/net/i40e/i40e_ethdev.h | 12 + drivers/net/i40e/i40e_vf_representor.c | 392 +++++++++++++++++++++++++++++++++ drivers/net/i40e/meson.build | 4 +- drivers/net/i40e/rte_pmd_i40e.c | 43 ++++ drivers/net/i40e/rte_pmd_i40e.h | 18 ++ 7 files changed, 535 insertions(+), 8 deletions(-) create mode 100644 drivers/net/i40e/i40e_vf_representor.c diff --git a/drivers/net/i40e/Makefile b/drivers/net/i40e/Makefile index 5663f5b1c..6184b38f3 100644 --- a/drivers/net/i40e/Makefile +++ b/drivers/net/i40e/Makefile @@ -11,6 +11,8 @@ LIB = librte_pmd_i40e.a CFLAGS += -O3 CFLAGS += $(WERROR_FLAGS) -DPF_DRIVER -DVF_DRIVER -DINTEGRATED_VF CFLAGS += -DX722_A0_SUPPORT +CFLAGS += -DALLOW_EXPERIMENTAL_API + LDLIBS += -lrte_eal -lrte_mbuf -lrte_mempool -lrte_ring LDLIBS += -lrte_ethdev -lrte_net -lrte_kvargs -lrte_hash LDLIBS += -lrte_bus_pci @@ -85,6 +87,7 @@ SRCS-$(CONFIG_RTE_LIBRTE_I40E_PMD) += i40e_fdir.c SRCS-$(CONFIG_RTE_LIBRTE_I40E_PMD) += i40e_flow.c SRCS-$(CONFIG_RTE_LIBRTE_I40E_PMD) += rte_pmd_i40e.c SRCS-$(CONFIG_RTE_LIBRTE_I40E_PMD) += i40e_tm.c +SRCS-$(CONFIG_RTE_LIBRTE_I40E_PMD) += i40e_vf_representor.c ifeq ($(findstring RTE_MACHINE_CPUFLAG_AVX2,$(CFLAGS)),RTE_MACHINE_CPUFLAG_AVX2) CC_AVX2_SUPPORT=1 diff --git a/drivers/net/i40e/i40e_ethdev.c b/drivers/net/i40e/i40e_ethdev.c index 508b4171c..397d834ed 100644 --- a/drivers/net/i40e/i40e_ethdev.c +++ b/drivers/net/i40e/i40e_ethdev.c @@ -18,6 +18,7 @@ #include #include #include +#include #include #include #include @@ -213,7 +214,7 @@ /* Bit mask of Extended Tag enable/disable */ #define PCI_DEV_CTRL_EXT_TAG_MASK (1 << PCI_DEV_CTRL_EXT_TAG_SHIFT) -static int eth_i40e_dev_init(struct rte_eth_dev *eth_dev);
