We introduce two new enum values for the irq domain flag: - IRQ_DOMAIN_FLAG_MSI indicates the irq domain corresponds to an MSI domain - IRQ_DOMAIN_FLAG_MSI_REMAP indicates the irq domain has MSI remapping capabilities. Those values will be useful to check all MSI irq domains have MSI remapping support when assessing the safety of IRQ assignment to a guest. irq_domain_hierarchical_is_msi_remap() allows to check if an irq domain or any parent implements MSI remapping.

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.
