[dpdk-dev] [PATCH v7 3/4] eal/linux: vfio: ignore mapping for ioport region

vfio_pci_mmap() try to map all pci bars. ioport region are not mapped in vfio/kernel so ignore mmaping for ioport. Signed-off-by: Santosh Shukla --- lib/librte_eal/linuxapp/eal/eal_pci_vfio.c | 20 1 file changed, 20 insertions(+) diff --git

[dpdk-dev] [PATCH v7 2/4] virtio: Introduce config RTE_VIRTIO_INC_VECTOR

- virtio_recv_pkts_vec and other virtio vector friend apis are written for sse/avx instructions. For arm64 in particular, virtio vector implementation does not exist(todo). So virtio pmd driver wont build for targets like i686, arm64. By making RTE_VIRTIO_INC_VECTOR=n, Driver can build for

[dpdk-dev] [PATCH v7 0/4] Add virtio support for arm/arm64

Hi, Patch series to allow access to virtio using vfio interface. Tested for vfio-noiommu mode for x86_64/arm64{thunderX} platform. patch series builds successfully for armv7/v8/x86_64/i686. Note: Rebased on David(s) recent patch series titled "rework virtio for ioport". Step to enable

[dpdk-dev] [PATCH v2 3/4] eal: introduce pci ioport api

Most of the code is inspired on virtio driver. rte_pci_ioport structure is filled at map time with anything needed for later read / write calls. At the moment, offset field is used to store a x86 ioport (uint16_t) and will be reused for other arches. TODO: check multi process, check intr_handle

[dpdk-dev] [PATCH v2 0/4] rework ioport access for virtio

Introduce a new pci ioport api in eal to mask all arch / kernel driver specifics. - rte_eal_pci_ioport_map is responsible for initialising an rte_pci_ioport object that is used in subsequent calls, this function must be tweaked per architecture and per kernel driver, - rte_eal_pci_ioport_read
