Triple Modular Redundancy(TMR) subsystem contains three microblaze cores, subsystem is fault-tolerant and continues to operate nominally after encountering an error. Together with the capability to detect and recover from errors, the implementation ensures the reliability of the entire subsystem. TMR Manager is responsible for performing recovery of the subsystem detects the fault via a break signal it invokes microblaze software break handler which calls the tmr manager driver api to update the error count and status, added support for fault detection feature via sysfs interface. Usage: To know the break handler count(Error count): cat /sys/devices/platform/amba_pl/44a10000.tmr_manager/errcnt Signed-off-by: Appana Durga Kedareswara rao <appana.durga.kedareswara.rao@amd.com> Link: https://lore.kernel.org/r/20221125054113.122833-3-appana.durga.kedareswara.rao@amd.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
