+What: /sys/class/reboot-mode/<driver>/reboot_modes
+Date: March 2026(TBD)
+KernelVersion: TBD
+Contact: linux-pm@vger.kernel.org
+ Description:
+ This interface exposes the reboot-mode arguments
+ registered with the reboot-mode framework. It is
+ a read-only interface and provides a space
+ separated list of reboot-mode arguments supported
+ on the current platform.
+ Example:
+ recovery fastboot bootloader
+
+ The exact sysfs path may vary depending on the
+ name of the driver that registers the arguments.
+ Example:
+ /sys/class/reboot-mode/nvmem-reboot-mode/reboot_modes
+ /sys/class/reboot-mode/syscon-reboot-mode/reboot_modes
+ /sys/class/reboot-mode/qcom-pon/reboot_modes
+
+ The supported arguments can be used by userspace to
+ invoke device reset using the standard reboot() system
+ call interface, with the "argument" as string to "*arg"
+ parameter along with LINUX_REBOOT_CMD_RESTART2.
+
+ A driver can expose the supported arguments by
+ registering them with the reboot-mode framework
+ using the property names that follow the
+ mode-<argument> format.
+ Example:
+ mode-bootloader, mode-recovery.
+
+ This attribute is useful for scripts or initramfs
+ logic that need to programmatically determine
+ which reboot-mode arguments are valid before
+ triggering a reboot.
