vfio-cdx driver enables IOCTLs for user space to query MMIO regions for CDX devices and mmap them. This change also adds support for reset of CDX devices. With VFIO enabled on CDX devices, user-space applications can also exercise DMA securely via IOMMU on these devices. This change adds the VFIO CDX driver and enables the following ioctls for CDX devices: - VFIO_DEVICE_GET_INFO: - VFIO_DEVICE_GET_REGION_INFO - VFIO_DEVICE_RESET Signed-off-by: Nipun Gupta <nipun.gupta@amd.com> Reviewed-by: Pieter Jansen van Vuuren <pieter.jansen-van-vuuren@amd.com> Tested-by: Nikhil Agarwal <nikhil.agarwal@amd.com> Link: https://lore.kernel.org/r/20230531124557.11009-1-nipun.gupta@amd.com Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
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.
