Date: Wed, 20 Feb 2019 09:34:21 +0000 [thread overview]
Message-ID: <20190220093424.5374-1-michaelsh@mellanox.com> (raw)
From: Michael Shych <michaelsh@mellanox.com>
This patchset introduces watchdog driver for a various range of Mellanox
Ethernet and Infiniband switch systems.
Mellanox watchdog device is implemented in programmable logic device.
There are 2 types of HW watchdog implementations with different capabilities.
This mlx-wdt driver supports both HW watchdog implementations.
Mellanox system can have 2 watchdogs: main and auxiliary.
Main and auxiliary watchdog devices can be enabled together on the same system.
There are several actions that can be defined in the watchdog:
system reset, start fans on full speed and increase register counter.
