selftests: move watchdog tests from Documentation/watchdog

2016-09-20T15:58:34+00:00

Remove watchdog-test from Makefile to move the test to selftests. Add Makefile and .gitignore for watchdog-test. watchdog-test will not be run as part of selftests suite and will not be included in install targets. It can be built separately for now.

Documentation/watchdog: check return value for magic close

2016-07-25T09:02:17+00:00

A recent commit added a write to the watchdog test code for doing the "magic close", but that caused a compile-time warning: Documentation/watchdog/src/watchdog-test.c: In function ‘main’: Documentation/watchdog/src/watchdog-test.c:94:5: warning: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Wunused-result] This changes the code to print a runtime warning if the write fails.

Documentation/watchdog: add support for magic close to watchdog-test

2016-07-17T19:02:32+00:00

Some drivers have the WDIOF_MAGICCLOSE set, which means that applications need to write 'V' to the watchdog device before closing, otherwise the driver won't stop the watchdog timer. Signed-off-by: Timur Tabi Reviewed-by: Guenter Roeck Signed-off-by: Guenter Roeck Signed-off-by: Wim Van Sebroeck

Documentation/watchdog: use stdout instead of stderr in watchdog-test

2016-07-17T19:02:29+00:00

The watchdog-test utility outputs all messages to stderr, even those that are not error messages. Output to stdout instead. Instead of flushing the output after every write, just disabled the output buffer. Also display a dot for every ping of the watchdog, so that the user knows that it's working.

Documentation/watchdog: add timeout and ping rate control to watchdog-test.c

2015-09-09T19:33:36+00:00

The watchdog test program is much more useful if it can configure the timeout value and ping rate. This will allow you to test actual timeouts. Adds the -t parameter to set the timeout value (in seconds), and -p to set the ping rate (number of seconds between pings).

Documentation/watchdog: Fix the file descriptor leak when no cmdline arg given

2012-05-23T14:27:48+00:00

we start a infinite loop when user gives ./watchdog-test, and when user ctrl + c's the program, we just exit immeadiately with out closing the filedescriptor of the watchdog device. a signal handler is used to do the job of closing the filedescriptor and exiting the program.

[WATCHDOG] doc: Fix use of WDIOC_SETOPTIONS ioctl.

2010-04-06T14:23:55+00:00

In the watchdog-test program and watchdog-api.txt, pass the values to the WDIOC_SETOPTIONS ioctl as a pointer to an integer containing the values intead of directly in the third ioctl argument. The actual watchdog drivers in drivers/watchdog don't read the options directly from the argument but use get_user and copy_from_user.
