2019-06-15watchdog: fix compile time error of pretimeout governorsVladimir Zapolskiy
[ Upstream commit a223770bfa7b6647f3a70983257bd89f9cafce46 ] CONFIG_WATCHDOG_PRETIMEOUT_GOV build symbol adds watchdog_pretimeout.o object to watchdog.o, the latter is compiled only if CONFIG_WATCHDOG_CORE is selected, so it rightfully makes sense to add it as a dependency.

This watchdog driver is a virtual driver in Linux and call ATF interface where call SCFW eventually. In SCFW, it's done by SCU timer tick instead of hardware watchdog.This is why we have to call ATF because such system resource owned by secure patition.Currently, booard reset happen if not ping this software watchdog in time in linux side, may change to partition reboot once SCFW support this feature in the future.

It occurred to me that the panic pretimeout governor will stall the softdog, because it is purely software which simply breaks when the kernel panics. Testing governors with the softdog on the other hand is really useful, so make this feature a compile time option which nees to be enabled explicitly. This also removes the overhead if pretimeout support is not used because it will now be compiled away (saving ~10% on ARM32).

The WDAT watchdog driver uses functionality provided by the watchdog timer core but it did not select it explicitly. This results following linker error when only WDAT_WDT is enabled in Kconfig: drivers/built-in.o: In function `wdat_wdt_probe': drivers/watchdog/wdat_wdt.c:444: undefined reference to `devm_watchdog_register_device' Fix this by explicitly selecting WATCHDOG_CORE when WDAT watchdog driver is enabled.

2016-10-08watchdog: pretimeout: add panic pretimeout governorVladimir Zapolskiy
The change adds panic watchdog pretimeout governor, on watchdog pretimeout event the kernel shall panic. In general watchdog pretimeout event means that something essentially bad is going on the system, for example a process scheduler stalls or watchdog feeder is killed due to OOM, so printing out information attendant to panic and before likely unavoidable reboot caused by a watchdog may help to determine a root cause of the issue.

2016-10-08watchdog: pretimeout: add noop pretimeout governorVladimir Zapolskiy
The change adds noop watchdog pretimeout governor, only an informational message is printed to the kernel log buffer when a watchdog triggers a pretimeout event. While introducing the first pretimeout governor the selected design assumes that the default pretimeout governor is selected by its name and it is always built-in, thus the default pretimeout governor can not be unregistered and the correspondent check can be removed from the watchdog_unregister_governor() function.

2016-10-08watchdog: add watchdog pretimeout governor frameworkVladimir Zapolskiy
The change adds a simple watchdog pretimeout framework infrastructure, its purpose is to allow users to select a desired handling of watchdog pretimeout events, which may be generated by some watchdog devices. A user selects a default watchdog pretimeout governor during compilation stage. Watchdogs with WDIOF_PRETIMEOUT capability now have one more device attribute in sysfs, pretimeout_governor attribute is intended to display the selected watchdog pretimeout governor. The framework has no impact at runtime on watchdog devices with no WDIOF_PRETIMEOUT capability set.

2016-09-24ACPI / watchdog: Add support for WDAT hardware watchdogMika Westerberg
Starting from Intel Skylake the iTCO watchdog timer registers were moved to reside in the same register space with SMBus host controller. Not all needed registers are available though and we need to unhide P2SB (Primary to Sideband) device briefly to be able to read status of required NO_REBOOT bit. The i2c-i801.c SMBus driver used to handle this and creation of the iTCO watchdog platform device. Windows, on the other hand, does not use the iTCO watchdog hardware directly even if it is available. Instead it relies on ACPI Watchdog Action Table (WDAT) table to describe the watchdog hardware to the OS. This table contains necessary information about the the hardware and also set of actions which are executed by a driver as needed. This patch implements a new watchdog driver that takes advantage of the ACPI WDAT table. We split the functionality into two parts: first part enumerates the WDAT table and if found, populates resources and creates platform device for the actual driver. The second part is the driver itself. The reason for the split is that this way we can make the driver itself to be a module and loaded automatically if the WDAT table is found. Otherwise the module is not loaded. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Rafael J.
