Adding unit tests for VFIO interrupt type command-line parameter.
We don't know if VFIO is compiled (eal_vfio.h header is internal
to Linuxapp EAL), so we check this flag regardless.

* [dpdk-dev] [PATCH 00/16] [RFC] [VFIO] Add VFIO support to DPDK
@ 2014-05-01 11:05 Burakov, Anatoly

This patchset adds support for using VFIO instead of IGB_UIO to
map the device BARs.
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.

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
