V12 Changes: * Removed previously added `--legacy-kni` eal option. * Removed previously added kni specific mempool create routines and mempool populate routines. V11 Changes: * Added iova to kva address translation routines in kernel module to make it work in iova=va mode which enables DPDK to create kni devices on any kind of backed device/memory. * Added ``--legacy-kni`` eal option to make existing KNI applications work with DPDK 19.11 and later versions. * Removed previously added pci device info from kni device info struct. V10 Changes: * Fixed function return code on failure when min_chunk_size > pg_sz. * Marked new mempool populate routine as EXPERIMENTAL. V9 Changes: * Used rte_mempool_ops_calc_mem_size() instead of default handler in the new mempool populate routine. * Check min_chunk_size and return values. * Removed ethdev_info memset to '0' and moved pci dev_info populate into kni_dev_pci_addr_get() routine. * Addressed misc. review comments. V8 Changes: * Remove default mempool populate() routine changes. * Add kni app specific mempool create & free routines. * Add new mempool populate routine to allocate page-aligned memzones with page size to make sure all mempool objects reside on a page. * Update release notes and map files. V7 Changes: * Removed previously proposed mempool flag and made those page boundary checks default in mempool populate() except for the objects size bigger than the size of page. * Removed KNI example application related changes since pool related requirement is taken care in mempool lib. * All PCI dev related info is moved under rte_eal_iova_mode() == VA check. * Added wrapper functions in KNI module to hide IOVA checks and make address translation routines more readable. * Updated IOVA mode checks that enforcing IOVA=PA mode when IOVA=VA mode is enabled. V6 Changes: * Added new mempool flag to ensure mbuf memory is not scattered across page boundaries. * Added KNI kernel module required PCI device information. * Modified KNI example application to create mempool with new mempool flag. V5 changes: * Fixed build issue with 32b build V4 changes: * Fixed build issues with older kernel versions * This approach will only work with kernel above 4.4.0 David Marchand (1): kni: support IOVA mode Vamsi Attunuru (1): kni: support IOVA mode in kernel module doc/guides/prog_guide/kernel_nic_interface.rst | 14 +++++ doc/guides/rel_notes/release_19_11.rst | 13 ++++- kernel/linux/kni/compat.h | 14 +++++ kernel/linux/kni/kni_dev.h | 42 +++++++++++++++ kernel/linux/kni/kni_misc.c | 39 ++++++++++---- kernel/linux/kni/kni_net.c | 62 ++++++++++++++++++----- lib/librte_eal/linux/eal/eal.c | 11 +++- lib/librte_eal/linux/eal/include/rte_kni_common.h | 1 + lib/librte_kni/rte_kni.c | 5 ++ 9 files changed, 176 insertions(+), 25 deletions(-) -- 2.8.4
