See: https://forum.libreelec.tv/thread/24783-tv-avr-turns-back-on-right-after-turning-them-off While the kernel provides a :D flag for assuming device is connected, it doesn't stop this function from being called and generating a cec_phys_addr_invalidate message when hotplug is deasserted. That message provokes a flurry of CEC messages which for many users results in the TV switching back on again and it's very hard to get it to stay switched off. It seems to only occur with an AVR and TV connected but has been observed across a number of manufacturers. The issue started with https://github.com/raspberrypi/linux/pull/4371 and this provides an optional way of getting back the old behaviour Signed-off-by: Dom Cobley <popcornmix@gmail.com>
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.
