Changes:\n* For KNI case, to restore the existing behaviour, forcing IOVA as PA\nif bus iommu returns IOVA_DC.\n* Restored phys_addr and kni_lib defination checks.\n* Simplified patch titles.\n* Updated documentation about patch set's impact on performance and\nkernel version requirement.\n\nV12 Changes:\n* Removed previously added `--legacy-kni` eal option.\n* Removed previously added kni specific mempool create routines\nand mempool populate routines.\n\nV11 Changes:\n* Added iova to kva address translation routines in kernel module to\nmake it work in iova=va mode which enables DPDK to create kni devices\non any kind of backed device/memory.\n* Added ``--legacy-kni`` eal option to make existing KNI applications\nwork with DPDK 19.11 and later versions.\n* Removed previously added pci device info from kni device info struct.\n \nV10 Changes:\n* Fixed function return code on failure when min_chunk_size > pg_sz.\n* Marked new mempool populate routine as EXPERIMENTAL.\n \nV9 Changes:\n* Used rte_mempool_ops_calc_mem_size() instead of default handler in the\nnew mempool populate routine.\n* Check min_chunk_size and return values.\n* Removed ethdev_info memset to '0' and moved pci dev_info populate into\nkni_dev_pci_addr_get() routine.\n* Addressed misc. review comments.\n \nV8 Changes:\n* Remove default mempool populate() routine changes.\n* Add kni app specific mempool create & free routines.\n* Add new mempool populate routine to allocate page-aligned memzones\nwith page size to make sure all mempool objects reside on a page.\n* Update release notes and map files.\n \nV7 Changes:\n* Removed previously proposed mempool flag and made those page\nboundary checks default in mempool populate() except for the objects size\nbigger than the size of page.\n* Removed KNI example application related changes since pool related\nrequirement is taken care in mempool lib.\n* All PCI dev related info is moved under rte_eal_iova_mode() == VA check.\n* Added wrapper functions in KNI module to hide IOVA checks and make\naddress translation routines more readable.\n* Updated IOVA mode checks that enforcing IOVA=PA mode when IOVA=VA\nmode is enabled.\n \nV6 Changes:\n* Added new mempool flag to ensure mbuf memory is not scattered across\npage boundaries.\n* Added KNI kernel module required PCI device information.\n* Modified KNI example application to create mempool with new mempool\nflag.\n \nV5 changes:\n* Fixed build issue with 32b build\n \nV4 changes:\n* Fixed build issues with older kernel versions\n* This approach will only work with kernel above 4.4.0\n\nDavid Marchand (1):\n kni: support IOVA mode\n\nVamsi Attunuru (1):\n kni: support IOVA mode in kernel module\n\n doc/guides/prog_guide/kernel_nic_interface.rst | 14 +++++\n
