There are devices (like IDT PCIe switches), which outbound MWs xlat address is setup on peer side. In this case local side is supposed to allocate a memory buffer and somehow deliver the xlat DMA address to peer so one could set the outbound MW up. The MW test is altered so to support both previous Intel/AMD and new IDT-like devices. Signed-off-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
