What: /sys/class/reboot-mode//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- 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.
