In order to make generic IOV code work, the physical function IOV BAR should start from offset of the first VF. Since M64 segments share PE number space across PHB, and some PEs may be in use at the time when IOV is enabled, the existing code shifts the IOV BAR to the index of the first PE/VF. This creates a hole in IOMEM space which can be potentially taken by some other device. This reserves a temporary hole on a parent and releases it when IOV is disabled; the temporary resources are stored in pci_dn to avoid kmalloc/free.

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.
