Currently, YUV hardware overlays are converted to RGB using a color space conversion different than BT.601. The result is that colors of e.g. NV12 buffers don't match colors of YUV hardware overlays. In order to fix this, enable YUV2YUV and set appropriate coefficients for formats such as NV12 to be displayed correctly. This commit was tested using modetest, gstreamer and chromeos (hardware accelerated video playback). Before the commit, tests rendering with NV12 format resulted in colors not displayed correctly. Test examples (Tested on RK3399 and RK3288 boards connected to HDMI monitor): $ modetest 39@32:1920x1080@NV12 $ gst-launch-1.0 videotestrc ! video/x-raw,format=NV12 ! kmssink Signed-off-by: Daniele Castagna <dcastagna@chromium.org> [ezequiel: rebase on linux-next and massage commit log] Signed-off-by: Ezequiel Garcia <ezequiel@collabora.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Link: https://patchwork.freedesktop.org/patch/msgid/20190108214659.28794-1-ezequiel@collabora.com |

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.
