Armada XP does not only support MSI, but also MSI-X. This patch sets the MSI_FLAG_PCI_MSIX flag in the interrupt controller driver which is the only change necessary to enable MSI-X support on this SoC. As the Linux PCI MSI-X infrastructure takes care of writing the data and address structures into the BAR specified by the MSI-X controller.

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.
