This introduces the required definitions for HEVC decoding support with stateless VPUs. The controls associated to the HEVC slice format provide the required meta-data for decoding slices extracted from the bitstream. They are not exported to the public V4L2 API since reworking this API will likely be needed for covering various use-cases and new hardware. Multi-slice decoding is exposed as a valid decoding mode to match current H.264 support but it is not yet implemented. The interface comes with the following limitations: * No custom quantization matrices (scaling lists); * Support for a single temporal layer only; * No slice entry point offsets support; * No conformance window support; * No VUI parameters support; * No support for SPS extensions: range, multilayer, 3d, scc, 4 bits; * No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.

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.
