This patch adds support for controller rumble. The ff_effect weak magnitude is associated with the pro controller's right motor (or with a right joy-con). The strong magnitude is associated with the pro's left motor (or a left joy-con). The rumble data is sent periodically (currently configured for every 50 milliseconds). If the controller receives no rumble data for too long a time period, it will stop vibrating. The data is also sent every time joycon_set_rumble is called to avoid latency of up to 50ms. Because the rumble subcommands are sent in a deferred workqueue (they can't be sent in the play_effect function due to the hid send sleeping), the effects are queued. This ensures that no rumble effect is missed due to them arriving in too quick of succession. Signed-off-by: Daniel J. Ogorchock <djogorchock@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
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.
