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.

The current implementation of i915 prime mmap only works when initializing drm_i915_gem_object with shmem_region. When using LMEM, drm_i915_gem_object is initialized with ttm_system_region. In order to make prime mmap work even this case, when using LMEM (when using ttm in i915), dma_buf_ops.mmap callback function calls drm_gem_prime_mmap(). drm_gem_prime_mmap() of drm core calls internally i915_gem_mmap() so that prime mmap can perform normally. The fake offset is processed inside drm_gem_prime_mmap().
