watchdog: WatchDog Timer Driver Core - Add minimum and max timeout

2011-07-28T08:01:18Z

Add min_timeout (minimum timeout) and max_timeout values so that the framework can check if the new timeout value is between the minimum and maximum timeout values. If both values are 0, then the framework will leave the check for the watchdog device driver itself.

watchdog: WatchDog Timer Driver Core - Add ioctl call

2011-07-28T08:01:16Z

Add support for extra ioctl calls by adding a ioctl watchdog operation. This operation will be called before we do our own handling of ioctl commands. This way we can override the internal ioctl command handling and we can also add extra ioctl commands. The ioctl watchdog operation should return the appropriate error codes or -ENOIOCTLCMD if the ioctl command should be handled through the internal ioctl handling of the framework.

watchdog: WatchDog Timer Driver Core - Add nowayout feature

2011-07-28T08:01:14Z

Add support for the nowayout feature to the WatchDog Timer Driver Core framework. This feature prevents the watchdog timer from being stopped. Signed-off-by: Alan Cox Signed-off-by: Wim Van Sebroeck Acked-by: Arnd Bergmann Acked-by: Wolfram Sang

watchdog: WatchDog Timer Driver Core - Add basic ioctl functionality

2011-07-28T08:01:05Z

watchdog: WatchDog Timer Driver Core - Add basic framework

2011-07-28T08:01:04Z

The WatchDog Timer Driver Core is a framework that contains the common code for all watchdog-driver's. It also introduces a watchdog device structure and the operations that go with it. This is the introduction of this framework. This part supports the minimal watchdog userspace API (or with other words: the functionality to use /dev/watchdog's open, release and write functionality as defined in the simplest watchdog API). Extra functionality will follow in the next set of patches. Signed-off-by: Alan Cox Signed-off-by: Wim Van Sebroeck Acked-by: Arnd Bergmann Acked-by: Wolfram Sang

[WATCHDOG] add WDIOC_GETTIMELEFT ioctl

2006-06-20T17:00:30Z

Some watchdog drivers have the ability to report the remaining time before the system will reboot. With the WDIOC_GETTIMELEFT ioctl you can now read the time left before the watchdog would reboot your system. The following drivers support this new IOCTL: i8xx_tco.c, pcwd_pci.c and pcwd_usb.c .

[WATCHDOG] Pre-Timeout flags

2006-06-20T16:50:42Z

Some watchdog timers support the concept of a "pretimeout" which occurs some time before the real timeout. The pretimeout can be delivered via an interrupt or NMI and can be used to panic the system when it occurs (so you get useful information instead of a blind reboot).
