From: Kevin Traynor Date: Fri, 8 Mar 2019 09:28:55 +0000 (+0000) Subject: net/qede: support IOVA VA mode X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7aac5899df81f40c07a8047f410e7f2fcc62962d;p=dpdk.git net/qede: support IOVA VA mode Set RTE_PCI_DRV_IOVA_AS_VA in drv_flags. This allows initializing qede PMD as non-root also on Linux v4.x, where /proc/self/pagemap can't be acccessed without CAP_SYS_ADMIN privileges. The flag was introduced generically but not in pmds in: commit 815c7deaed2d ("pci: get IOMMU class on Linux") Cc: stable@dpdk.org Acked-by: Shahed Shaikh Acked-by: Rasesh Mody Signed-off-by: Kevin Traynor --- diff --git a/drivers/net/qede/qede_ethdev.c b/drivers/net/qede/qede_ethdev.c index 518673dce1..0b2f305e17 100644 --- a/drivers/net/qede/qede_ethdev.c +++ b/drivers/net/qede/qede_ethdev.c @@ -2735,7 +2735,8 @@ static int qedevf_eth_dev_pci_remove(struct rte_pci_device *pci_dev) static struct rte_pci_driver rte_qedevf_pmd = { .id_table = pci_id_qedevf_map, - .drv_flags = RTE_PCI_DRV_NEED_MAPPING | RTE_PCI_DRV_INTR_LSC, + .drv_flags = RTE_PCI_DRV_NEED_MAPPING | RTE_PCI_DRV_INTR_LSC | + RTE_PCI_DRV_IOVA_AS_VA, .probe = qedevf_eth_dev_pci_probe, .remove = qedevf_eth_dev_pci_remove, }; @@ -2754,7 +2755,8 @@ static int qede_eth_dev_pci_remove(struct rte_pci_device *pci_dev) static struct rte_pci_driver rte_qede_pmd = { .id_table = pci_id_qede_map, - .drv_flags = RTE_PCI_DRV_NEED_MAPPING | RTE_PCI_DRV_INTR_LSC, + .drv_flags = RTE_PCI_DRV_NEED_MAPPING | RTE_PCI_DRV_INTR_LSC | + RTE_PCI_DRV_IOVA_AS_VA, .probe = qede_eth_dev_pci_probe, .remove = qede_eth_dev_pci_remove, };
