The following series implements rdmavt. This is the rdma verbs transport software library which will help to solve the problem of code duplication between hardware drivers when it comes to a verbs implementation.
Rdmavt is basically just another verbs provider and lives in the Infiniband tree in a new sw directory. It provides a software implementation of the Infiniband verbs API. More details can be found in the following threads: http://www.spinics.net/lists/linux-rdma/msg29064.html http://www.spinics.net/lists/linux-rdma/msg29922.html This patch series is based on what appears to be the latest branch on Doug's kernel.org repo (k.o/for-4.4-rc). I can rebase onto something else if needed. Changes since v1: Removed driver specific version Fixed license text to remove copyright and put on top Return 0 in rvt_map_sg instead of BAD_DMA_AGGRESS Remove #include of dma.h from dma.c Update comment about protection domain limit Remove comment on alternative design for private data Rename CDR macro to CHECK_DRIVER_OVERRIDE Change all the stubs to return EOPNOTSUPP Fix comment style for rvt_query_port Fix typo in subject Rename rdi.lk_table to rdi.lkey_table Rename rvt_sge.m => rvt_sge.cur_map (Sean) Rename rvt_sge.n => rvt_sge.cur_seg (Sean) Remove rvt_reg_phys_mr Drop support for commit 38071a461f0a ("IB/qib: Support the new memory registration API") --- Dennis Dalessandro (34): IB/rdmavt: Create module framework and handle driver registration IB/rdmavt: Consolidate dma ops in rdmavt.
