Some form factors (detachables/tablets) may not have a keyboard and thus user may have to resort to using a defined EC UI to send sysrq(s) to the kernel in order to collect crash info etc. This UI typically is in the form of user pressing volume / power buttons in some specific sequence and for some specific time. Add a new EC event that allows EC to communicate the sysrq to the AP. (We're skipping event number 5 because it has been reserved for something else) Signed-off-by: Rajat Jain <rajatja@google.com> Acked-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
