Pull VFIO updates from Alex Williamson: - Relax IGD support code to match display class device rather than specifically requiring a VGA device (Tomita Moeko) - Accelerate DMA mapping of device MMIO by iterating at PMD and PUD levels to take advantage of huge pfnmap support added in v6.12 (Alex Williamson) - Extend virtio vfio-pci variant driver to include migration support for block devices where enabled by the PF (Yishai Hadas) - Virtualize INTx PIN register for devices where the platform does not route legacy PCI interrupts for the device and the interrupt is reported as IRQ_NOTCONNECTED (Alex Williamson) * tag 'vfio-v6.15-rc1' of https://github.com/awilliam/linux-vfio: vfio/pci: Handle INTx IRQ_NOTCONNECTED vfio/virtio: Enable support for virtio-block live migration vfio/type1: Use mapping page mask for pfnmaps mm: Provide address mask in struct follow_pfnmap_args vfio/type1: Use consistent types for page counts vfio/type1: Use vfio_batch for vaddr_get_pfns() vfio/type1: Convert all vaddr_get_pfns() callers to use vfio_batch vfio/type1: Catch zero from pin_user_pages_remote() vfio/pci: match IGD devices in display controller class
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
