The V3D MMU also supports 64KB and 1MB pages, called big and super pages, respectively. In order to set a 64KB page or 1MB page in the MMU, we need to make sure that page table entries for all 4KB pages within a big/super page must be correctly configured. In order to create a big/super page, we need a contiguous memory region. That's why we use a separate mountpoint with THP enabled. In order to place the page table entries in the MMU, we iterate over the 16 4KB pages (for big pages) or 256 4KB pages (for super pages) and insert the PTE.

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 reStructuredText 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.
