CONFIG_FW_LOADER_USER_HELPER_FALLBACK: Force the firmware sysfs fallback mechanism when possible

General informations

The Linux kernel configuration item CONFIG_FW_LOADER_USER_HELPER_FALLBACK has multiple definitions:

Fallback user-helper invocation for firmware loading found in drivers/base/Kconfig

The configuration item CONFIG_FW_LOADER_USER_HELPER_FALLBACK:

Help text

This option enables / disables the invocation of user-helper (e.g. udev) for loading firmware files as a fallback after the direct file loading in kernel fails. The user-mode helper is no longer required unless you have a special firmware file that resides in a non-standard path. Moreover, the udev support has been deprecated upstream.

If you are unsure about this, say N here.

Force the firmware sysfs fallback mechanism when possible found in drivers/base/firmware_loader/Kconfig

The configuration item CONFIG_FW_LOADER_USER_HELPER_FALLBACK:

Help text

Enabling this option forces a sysfs userspace fallback mechanism to be used for all firmware requests which explicitly do not disable a a fallback mechanism. Firmware calls which do prohibit a fallback mechanism is request_firmware_direct(). This option is kept for backward compatibility purposes given this precise mechanism can also be enabled by setting the proc sysctl value to true:

/proc/sys/kernel/firmware_config/force_sysfs_fallback

If you are unsure about this, say N here.
