Linux kernel source tree

We already wrap i915_vma.node.start for use with the GGTT, as there we can perform additional sanity checks that the node belongs to the GGTT and fits within the 32b registers. In the next couple of patches, we will introduce guard pages around the objects _inside_ the drm_mm_node allocation. That is we will offset the vma->pages so that the first page is at drm_mm_node.start + vma->guard (not 0 as is currently the case). All users must then not use i915_vma.node.start directly, but compute the guard offset, thus all users are converted to use a i915_vma_offset() wrapper. The notable exceptions are the selftests that are testing exact behaviour of i915_vma_pin/i915_vma_insert.

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.
