What: /sys/class/reboot-mode/<driver>/reboot_modes

KernelVersion: 6.17.0-rc1
4+
Contact: linux-pm@vger.kernel.org
5+
Description:
6+
This interface exposes the reboot-mode arguments
7+
registered with the reboot-mode framework. It is
8+
a read-only interface and provides a space
9+
separated list of reboot-mode arguments supported
10+
on the current platform.
11+
Example:
12+
recovery fastboot bootloader
13+
14+
The exact sysfs path may vary depending on the
15+
name of the driver that registers the arguments.
16+
Example:
17+
/sys/class/reboot-mode/nvmem-reboot-mode/reboot_modes
18+
/sys/class/reboot-mode/syscon-reboot-mode/reboot_modes
19+
/sys/class/reboot-mode/qcom-pon/reboot_modes
20+
21+
The supported arguments can be used by userspace
22+
to invoke device reset using the reboot() system
23+
call, with the "argument" as string to "*arg"
24+
parameter along with LINUX_REBOOT_CMD_RESTART2.
25+
Example:
26+
reboot(LINUX_REBOOT_MAGIC1, LINUX_REBOOT_MAGIC2,
27+
LINUX_REBOOT_CMD_RESTART2, "bootloader");
28+
29+
A driver can expose the supported arguments by
30+
registering them with the reboot-mode framework
31+
using the property names that follow the
32+
mode-<argument> format.
33+
Example:
34+
mode-bootloader, mode-recovery.
35+
36+
This attribute is useful for scripts or initramfs
37+
logic that need to programmatically determine
38+
which reboot-mode arguments are valid before
39+
triggering a reboot.
