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.

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: use subdir-y to avoid unnecessary built-in.o files

2014-09-26T09:02:55+00:00

Change the Documentation makefiles from obj-m to subdir-y
to avoid generating unnecessary built-in.o files since nothing
in Documentation/ is ever linked in to vmlinux.

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.
