Linus Torvalds deefd5024f VFIO updates for v6.7
- Add support for "chunk mode" in the mlx5-vfio-pci variant driver,
    which allows both larger device image sizes for migration, beyond
    the previous 4GB limit, and also read-ahead support for improved
    migration performance. (Yishai Hadas)
 
  - A new bus master control interface for the CDX bus driver where
    there is no in-band mechanism to toggle device DMA as there is
    through config space on PCI devices. (Nipun Gupta)
 
  - Add explicit alignment directives to vfio data structures to
    reduce the chance of breaking 32-bit userspace.  In most cases
    this is transparent and the remaining cases where data structures
    are padded work within the existing rules for extending data
    structures within vfio.  (Stefan Hajnoczi)
 
  - Resolve a bug in the cdx bus driver noted when compiled with clang
    where missing parenthesis result in the wrong operation.
    (Nathan Chancellor)
 
  - Resolve errors reported by smatch for a function when dealing
    with invalid inputs. (Alex Williamson)
 
  - Add migration support to the mtty vfio/mdev sample driver for
    testing and integration purposes, allowing CI of migration without
    specific hardware requirements.  Also resolve many of the short-
    comings of this driver relative to implementation of the vfio
    interrupt ioctl along the way. (Alex Williamson)

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 Restructured Text 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.
