请求帮助，x96max，关于linux定时休眠、定时开关机的可能性讨论。

如果每天晚上23点开机，早上7点自动开机，对于轻度使用还是很不错的。我通过查询资料得到：
root@armbian:# cat /sys/power/state
root@armbian:# cat /proc/driver/rtc
rtc_time : 00:45:29
rtc_date : 2026-01-16
alrm_time : 00:00:00
alrm_date : 1970-01-01
alarm_IRQ : no
alrm_pending : no
update IRQ enabled : no
periodic IRQ enabled : no
periodic IRQ frequency : 1
max user IRQ frequency : 64
24hr : yes
root@armbian:~# ethtool eth0
Settings for eth0:
Supports Wake-on: ug
Wake-on: d

这些参数代表支持网络唤醒，但是“cat /sys/power/state”输出为空代表内核缺失功能，请问哪一版本才能获取完整的电源管理。

尝试刷入Armbian_26.02.0_amlogic_s905x3_jammy_6.1.160_server_2026.01.15.img，"cat /sys/power/state"也无任何输出。

Ai分析是缺失某些选项导致：
` CONFIG_SUSPEND is not set

CONFIG_HIBERNATION is not set
`
有人能给于一些思路吗

[6LWa6ZKx]

https://github.com/ophub/kernel/blob/main/kernel-config/release/stable/config-6.1

我找到了这些编译配置：

`
# Power management options

#
# CONFIG_SUSPEND is not set

# CONFIG_HIBERNATION is not set

CONFIG_PM=y

# CONFIG_PM_DEBUG is not set

CONFIG_PM_CLK=y

CONFIG_PM_GENERIC_DOMAINS=y

# CONFIG_WQ_POWER_EFFICIENT_DEFAULT is not set

CONFIG_PM_GENERIC_DOMAINS_OF=y

CONFIG_CPU_PM=y

CONFIG_ENERGY_MODEL=y

CONFIG_ARCH_HIBERNATION_POSSIBLE=y

CONFIG_ARCH_SUSPEND_POSSIBLE=y

# end of Power management options`

是出于什么考虑，而关闭了一些功能呢

[6LWa6ZKx]

我通过fork、action增加config-6.1中的：

CONFIG_SUSPEND=y
CONFIG_HIBERNATION=y

重新构建内核并且armbian-update 。
现在测试得到了：

root@armbian:# cat /sys/power/state
freeze mem disk
root@armbian:# ls /sys/class/rtc/
rtc0
root@armbian:# cat /proc/driver/rtc
rtc_time : 08:41:43

alrm_pending : no
update IRQ enabled : no
periodic IRQ enabled : no
periodic IRQ frequency : 1
max user IRQ frequency : 64

op大佬看到了，麻烦指点下，我的构建、更新正确吗？我希望后续能跟上你的版本更新。
