> 你好，
> 
> 你的主板8A4D目前没有出现在hp-wmi驱动的任何白名单中。因此，它默认使用传统的Omen WMI接口来注册平台配置文件。
> 
> 从你在 Omen Gaming Hub 的日志和 EC 转储来看，很明显你的主板需要更新的 Victus S 风格的 WMI
> 查询来切换平台配置文件（以及与粉丝相关的活动），而不是传统查询。

> 请您应用以下补丁并测试以下内容：
> 1. 查看dmesg是否成功注册信息：
>    “hp_wmi：注册为平台配置文件管理员”
> 
> 2. 确认风扇转速可通过sysfs（/sys/devices/platform/hp-wmi/hwmon/*）读取和控制。
> 
> 3. 在更改平台配置文件时验证这一点，它确实会物理上改变CPU/GPU的耗电量。

Hello Krishna,

I successfully applied the patch to the mainline RC kernel and thoroughly
tested it on my board (8A4D). The results are fantastic:
❯ echo 255 | sudo tee /sys/class/hwmon/hwmon6/pwm1
255

❯ sudo dmesg | grep hp_wmi

 Sysfs nodes are populated correctly (performance, balanced, low-power).
Switching to the "performance" profile works flawlessly and successfully
unlocks the hardware power limits—I can confirm the CPU reaches 115W under full
load!

The patch brings full and essential support for the Omen 8A4D board. Thank you
so much for your hard work!
