All in-kernel references to the old paths have been updated.

This is an LSFMM outcome that, it is hoped, will help encourage developers to fill in the many gaps. Optimism is eternal...but hopefully it will work. - More Chinese translations.

This documentation describes the basics of IFS, the loading IFS image, chunk authentication, running scan and how to check result via sysfs. The CORE_CAPABILITIES MSR enumerates whether IFS is supported. The full github location for distributing the IFS images is still being decided. So just a placeholder included for now in the documentation. Future CPUs will support more than one type of test. Plan for that now by using a "_0" suffix on the ABI directory names. Additional test types will use "_1", etc. Reviewed-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com> Reviewed-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/r/20220506225410.1652287-13-tony.luck@intel.com Signed-off-by: Hans de Goede <hdegoede@redhat.com> 2022-04-28T13:59:45+00:00 Alex Deucher alexander.deucher@amd.com 2022-04-22T19:26:56+00:00 urn:sha1:2a8d78d566faa3d92214f161fdd7134957407871 Add preliminary documentation for AMD IOMMU and combine with the existing Intel IOMMU documentation and clean up and modernize some of the existing documentation to align with the current state of the kernel.
