Public methods
getDependentModules
public static String[] getDependentModules (String modName, String lsmodOutput)
Return the names of the modules that the given module depends on.
For example, if the given module is `kunit`, and the `lsmod` output is:
$ lsmod
Module Size Used by
kunit_test 663552 0
time_test 663558 0
kunit 57344 15 kunit_test,time_test
Then this method will return an array containing `kunit_test` and `time_test`.
Parameters | |

modName |
String |
lsmodOutput |

String[] |
getDisplayedModuleName
public static String getDisplayedModuleName (String fullPath)
Return module name as it's displayed after loading.
For example, see the difference between the file name and that returned by `lsmod`:
$ insmod kunit.ko
$ lsmod | grep kunit
kunit 20480 0

installModule
public static void installModule (ITestDevice device, String modulePath, String arg, long timeoutMs)
Install a kernel module on the given device.
Parameters | |
---|---|
device |
ITestDevice : the device to install the module on |
modulePath |
String : the path to the module to install |
arg |
String : the argument to pass to the install command |
timeoutMs |
long : the timeout in milliseconds |
Throws | |
---|---|
TargetSetupError |
if the module cannot be installed |
DeviceNotAvailableException |
if the device is not available |
removeKoExtension
public static String removeKoExtension (String s)
Remove `.ko` extension if present
Parameters | |
---|---|
s |
String |
Returns | |
---|---|
String |
removeModule
public static void removeModule (ITestDevice device, String module)
Remove a kernel module and dependent modules from the given device.
This method attempts to remove the target kernel module from the device. If the module has any dependencies, those dependent modules will be removed before the target module with best effort.
Parameters | |
---|---|
device |
ITestDevice : the device to remove the module from |
module |
String : the name or the path to the module to remove |
Throws | |
---|---|
DeviceNotAvailableException |
if the device is not available |
