In case the IOMMU translates MSI transactions (typical case on ARM), we check MSI remapping capability at IRQ domain level. Otherwise it is checked at IOMMU level. At this stage the arm-smmu-(v3) still advertise the IOMMU_CAP_INTR_REMAP capability at IOMMU level. This will be removed in subsequent patches.

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.
