[dpdk-dev] [PATCH v6 16/20] eal: make --no-huge use mmap instead of malloc

This makes it possible to run DPDK without hugepage memory when VFIO is used, as VFIO uses virtual addresses to set up DMA mappings. Technically, malloc is just fine, but we want to guarantee that memory will be page-aligned, so using mmap to be safe. --- lib/librte_eal/linuxapp/eal/eal_memory.c

[dpdk-dev] [PATCH v6 15/20] eal: added support for selecting VFIO interrupt type from EAL command-line

Unlike igb_uio, VFIO interrupt type is not set by kernel module parameters but is set up via ioctl() calls at runtime. This warrants a new EAL command-line parameter. It will have no effect if VFIO is not compiled, but will set VFIO interrupt type to either "legacy", "msi" or "msix" if VFIO

[dpdk-dev] [PATCH v6 13/20] vfio: add multiprocess support.

Since VFIO cannot be used to map the same device twice, secondary processes receive the device/group fd's by means of communicating over a local socket. Only group and container fd's should be sent, as device fd's can be obtained via ioctl() calls' on the group fd. For multiprocess, VFIO

[dpdk-dev] [PATCH v6 12/20] vfio: create mapping code for VFIO

Adding code to support VFIO mapping (primary processes only). Most of the things are done via ioctl() calls on either /dev/vfio/vfio (the container) or a /dev/vfio/$GROUP_NR (IOMMU group). In a nutshell, the code does the following: 1. creates a VFIO container (an entity that allows sharing IOMMU
