Together with the capability to detect and recoverfrom errors, the implementation ensures the reliability of the entiresubsystem. TMR Manager is responsible for performing recovery of thesubsystem detects the fault via a break signal it invokes microblazesoftware break handler which calls the tmr manager driver api toupdate the error count and status, added support for fault detectionfeature via sysfs interface.Usage:To know the break handler count(Error count):cat /sys/devices/platform/amba_pl/44a10000.tmr_manager/errcntSigned-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.comSigned-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> List of files: /linux-6.15/Documentation/ABI/testing/sysfs-driver-xilinx-tmr-manager Fri, 25 Nov 2022 05:41:11 +0000 Appana Durga Kedareswara rao <appana.durga.kedareswara.rao@amd.com>
