After the global KeyID has been configured on all packages, initialize all TDMRs to make all TDX-usable memory regions that are passed to the TDX module become usable. This is the last step of initializing the TDX module. Initializing TDMRs can be time consuming on large memory systems as it involves initializing all metadata entries for all pages that can be used by TDX guests. Initializing different TDMRs can be parallelized. For now to keep it simple, just initialize all TDMRs one by one. It can be enhanced in the future.

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.
