Some VT-d hardware implementations invalidate all interrupt remapping hardware translation caches as part of SIRTP flow. The VT-d spec adds a ESIRTPS (Enhanced Set Interrupt Remap Table Pointer Support, section 11.4.2 in VT-d spec) capability bit to indicate this. The spec also states in 11.4.4 that hardware also performs global invalidation on all interrupt remapping caches as part of Interrupt Remapping Disable operation if ESIRTPS capability bit is set. This checks the ESIRTPS capability bit and skip software global cache invalidation if it's set.

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.
