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
v2 fixes:
* Fixed a couple of resource leaks
v3 fixes:
* Fixed various checkpatch.pl issues
* Added MSI interrupt support
* Added an option to automatically determine interrupt type
* Fixed various issues of commit atomicity
v4 fixes:
* Rebased on top of 5ebbb17281645b23359fbd49133bb639b63ba88c
* Fixed a typo in EAL command-line help text
v5 fixes:
* Fixed missing virtio change to RTE_PCI_DRV_NEED_MAPPING
* Fixed compile issue when VFIO was disabled (introduced in v3)
v6 fixes:
* Rebased on top of 36c248ebc629889fff4e7d9d17e109412ddf9ecf
* Fixed FreeBSD issue with failed unbinds (introduced in v1)
* Fixed a few issues found by checkpatch
Tested-by: Waterman Cao <waterman.cao@intel.com>
This patch has been tested by intel.
We tested this patch with the following functions:
* Layer-2 Forwarding support
* Sample commands test
* Packet forwarding checking
* Bind and unbind VFIO driver
* Compile igb_uio driver ( Linux kernel < 3.6)
* Interrupt model test under Legacy|msi|msix
All cases passed.
Please see test environment information :
Fedora 20 x86_64, Linux Kernel 3.13.6-200,
GCC 4.8.2 Intel Xeon CPU E5-2680 v2 @ 2.80GHz NIC: Intel Niantic 82599
