# Watchdog device configuration
#
menuconfig WATCHDOG
bool "Watchdog Timer Support"
---help---
If you say Y here (and to one of the following options) and create a
character special file /dev/watchdog with major number 10 and minor
number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
subsequently opening the file and then failing to write to it for
longer than 1 minute will result in rebooting the machine. This
could be useful for a networked machine that needs to come back
on-line as fast as possible after a lock-up. There's both a watchdog
implementation entirely in software (which can sometimes fail to
reboot the machine) and a driver for hardware watchdog boards, which
are more robust and can also keep track of the temperature inside
your computer. For details, read
<file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
The watchdog is usually used together with the watchdog daemon
which is available from
<ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
also monitor NFS connections and can reboot the machine when the process
table is full.
If unsure, say N.
if WATCHDOG
config WATCHDOG_CORE
bool "WatchDog Timer Driver Core"
---help---
Say Y here if you want to use the new watchdog timer driver core.
This driver provides a framework for all watchdog timer drivers
and gives them the /dev/watchdog interface (and later also the
sysfs interface).
config WATCHDOG_NOWAYOUT
bool "Disable watchdog shutdown on close"
help
The default watchdog behaviour (which you get if you say N here) is
to stop the timer if the process managing it closes the file
/dev/watchdog. It's always remotely possible that this process might
get killed. If you say Y here, the watchdog cannot be stopped once
it has been started.
config WATCHDOG_SYSFS
bool "Read different watchdog information through sysfs"
help
Say Y here if you want to enable watchdog device status read through
sysfs attributes.

config SOFT_WATCHDOG
tristate "Software watchdog"
select WATCHDOG_CORE
help
A software monitoring watchdog. This will fail to reboot your system
from some situations that the hardware watchdog will recover
from. Equally it's a lot cheaper to install.
To compile this driver as a module, choose M here: the
module will be called softdog.
config SOFT_WATCHDOG_PRETIMEOUT
bool "Software watchdog pretimeout governor support"
depends on SOFT_WATCHDOG && WATCHDOG_PRETIMEOUT_GOV
help
Enable this if you want to use pretimeout governors with the software
watchdog. Be aware that governors might affect the watchdog because it
is purely software, e.g. the panic governor will stall it!
config DA9052_WATCHDOG
tristate "Dialog DA9052 Watchdog"
depends on PMIC_DA9052 || COMPILE_TEST
select WATCHDOG_CORE
help
Support for the watchdog in the DA9052 PMIC. Watchdog trigger
cause system reset.
Say Y here to include support for the DA9052 watchdog.
Alternatively say M to compile the driver as a module,
which will be called da9052_wdt.
config DA9055_WATCHDOG
tristate "Dialog Semiconductor DA9055 Watchdog"
depends on MFD_DA9055 || COMPILE_TEST
select WATCHDOG_CORE
help
If you say yes here you get support for watchdog on the Dialog
Semiconductor DA9055 PMIC.
This driver can also be built as a module. If so, the module
will be called da9055_wdt.
config DA9063_WATCHDOG
tristate "Dialog DA9063 Watchdog"
depends on MFD_DA9063 || COMPILE_TEST
select WATCHDOG_CORE
help
Support for the watchdog in the DA9063 PMIC.
This driver can be built as a module. The module name is da9063_wdt.
config DA9062_WATCHDOG
tristate "Dialog DA9062/61 Watchdog"
depends on MFD_DA9062 || COMPILE_TEST
select WATCHDOG_CORE
help
Support for the watchdog in the DA9062 and DA9061 PMICs.
This driver can be built as a module. The module name is da9062_wdt.
config GPIO_WATCHDOG
tristate "Watchdog device controlled through GPIO-line"
depends on OF_GPIO
select WATCHDOG_CORE
help
If you say yes here you get support for watchdog device
controlled through GPIO-line.
config GPIO_WATCHDOG_ARCH_INITCALL
bool "Register the watchdog as early as possible"
depends on GPIO_WATCHDOG=y
help
In some situations, the default initcall level (module_init)
in not early enough in the boot process to avoid the watchdog
to be triggered.
If you say yes here, the initcall level would be raised to
arch_initcall.
If in doubt, say N.
config MENF21BMC_WATCHDOG
tristate "MEN 14F021P00 BMC Watchdog"
depends on MFD_MENF21BMC || COMPILE_TEST
depends on I2C
select WATCHDOG_CORE
help
Say Y here to include support for the MEN 14F021P00 BMC Watchdog.
This driver can also be built as a module. If so the module
will be called menf21bmc_wdt.
config TANGOX_WATCHDOG
tristate "Sigma Designs SMP86xx/SMP87xx watchdog"
select WATCHDOG_CORE
depends on ARCH_TANGO || COMPILE_TEST
depends on HAS_IOMEM
help
Support for the watchdog in Sigma Designs SMP86xx (tango3)
and SMP87xx (tango4) family chips.
This driver can be built as a module. The module name is tangox_wdt.
config WDAT_WDT
tristate "ACPI Watchdog Action Table (WDAT)"
depends on ACPI
select WATCHDOG_CORE
select ACPI_WATCHDOG
help
This driver adds support for systems with ACPI Watchdog Action
Table (WDAT) table. Servers typically have this but it can be
found on some desktop machines as well. This driver will take
over the native iTCO watchdog driver found on many Intel CPUs.
To compile this driver as module, choose M here: the module will
be called wdat_wdt.
config WM831X_WATCHDOG
tristate "WM831x watchdog"
depends on MFD_WM831X
select WATCHDOG_CORE
help
Support for the watchdog in the WM831x AudioPlus PMICs. When
the watchdog triggers the system will be reset.
config WM8350_WATCHDOG
tristate "WM8350 watchdog"
depends on MFD_WM8350
select WATCHDOG_CORE
help
Support for the watchdog in the WM8350 AudioPlus PMIC. When
the watchdog triggers the system will be reset.
config XILINX_WATCHDOG
tristate "Xilinx Watchdog timer"
depends on HAS_IOMEM
select WATCHDOG_CORE
help
Watchdog driver for the xps_timebase_wdt ip core.
To compile this driver as a module, choose M here: the
module will be called of_xilinx_wdt.
config ZIIRAVE_WATCHDOG
tristate "Zodiac RAVE Watchdog Timer"
depends on I2C
select WATCHDOG_CORE
help
Watchdog driver for the Zodiac Aerospace RAVE Switch Watchdog
Processor.
To compile this driver as a module, choose M here: the
module will be called ziirave_wdt.
# ALPHA Architecture
# ARM Architecture
config ARM_SP805_WATCHDOG
tristate "ARM SP805 Watchdog"
depends on (ARM || ARM64 || COMPILE_TEST) && ARM_AMBA
select WATCHDOG_CORE
help
ARM Primecell SP805 Watchdog timer. This will reboot your system when
the timeout is reached.
config ARM_SBSA_WATCHDOG
tristate "ARM SBSA Generic Watchdog"
depends on ARM64
depends on ARM_ARCH_TIMER
select WATCHDOG_CORE
help
ARM SBSA Generic Watchdog has two stage timeouts:
the first signal (WS0) is for alerting the system by interrupt,
