The Thread Control Structure (TCS) contains meta-data used by the hardware to save and restore thread specific information when entering/exiting the enclave. A TCS can be added to an initialized enclave by first adding a new regular enclave page, initializing the content of the new page from within the enclave, and then changing that page's type to a TCS. Support the initialization of a TCS from within the enclave. The variable information needed that should be provided from outside the enclave is the address of the TCS, address of the State Save Area (SSA), and the entry point that the thread should use to enter the enclave. With this information provided all needed fields of a TCS can be initialized.

README
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.
