* struct firmware_fallback_config - firmware fallback configuration settings
|
|
*
|
|
* Helps describe and fine tune the fallback mechanism.
|
|
*
|
|
* @force_sysfs_fallback: force the sysfs fallback mechanism to be used
|
|
* as if one had enabled CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y.
|
|
* Useful to help debug a CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y
|
|
* functionality on a kernel where that config entry has been disabled.
|
|
* @ignore_sysfs_fallback: force to disable the sysfs fallback mechanism.
|
|
* This emulates the behaviour as if we had set the kernel
|
|
* config CONFIG_FW_LOADER_USER_HELPER=n.
|
|
* @old_timeout: for internal use
|
|
* @loading_timeout: the timeout to wait for the fallback mechanism before
|
|
* giving up, in seconds.
