Watchdog Testing Documentation
|
||
|
|
|
||
|
|
Usage: msm_watchdog_test.sh TEST
|
||
|
|
Runs the basic watchdog test
|
||
|
|
|
||
|
|
TEST can be one of: apps_wdog_bite, sec_wdog_bite,
|
||
|
|
sec_wdog_scm, apps_wdog_bark
|
||
|
|
|
||
|
|
|
||
|
|
OPTIONS:
|
||
|
|
The module knows about the following parameters
|
||
|
|
|
||
|
|
- apps_wdog_bite
|
||
|
|
- sec_wdog_bite
|
||
|
|
- sec_wdog_scm
|
||
|
|
- apps_wdog_bark
|
||
|
|
|
||
|
|
Setting any of these to 1 at insmod time will cause the
|
||
|
|
corresponding test to be executed. For example, the following will
|
||
|
|
run the apps watchdog bark test:
|
||
|
|
|
||
|
|
# insmod msm_watchdog_test_module.ko apps_wdog_bark=1
|
||
|
|
|
||
|
|
However, rather than inserting the module directly and worrying
|
||
|
|
about supplying the correct parameters, you should use the wrapper
|
||
|
|
script: msm_watchdog_test.sh.
|
||
|
|
|
||
|
|
TEST BEHAVIOR:
|
||
|
|
* Test will force a watchdog timeout, which will reboot the system.
|
||
|
|
After obtaining rampdumps from debug mode, the ramdump parser
|
||
|
|
will produce the following results:
|
||
|
|
|

|
|

test failed.
