Fan Controls for OneXPlayer Super X

[sean89butler]

Everything in HHD works quite well for the new Super X device. However, there are currently no fan controls. The device is quite new so maybe the oxp-sensors doesn't support it yet?

Indeed. If you still have windows, the quickest way is to use https://rweverything.com/download/

Then, reference oxpec for the registers.

They should match an existing quirk. Tell me which it is and I will make a patch and send it to the kernel.

I installed Windows on an external SSD so I could install RWEverything. From what I can see, OXP_SENSOR_FAN_REG 0x76 & OXP_SENSOR_PWM_REG 0x4B match what I'm seeing in the EC. From what I can tell, both fans run simultaneously, they don't seem to have independent control

What about the fan speed register and the battery registers?

[sean89butler]

Ok, I think 0x4B is the fan speed register, I was running a stress test and watching it rise with the fan speed and drop as it lowered.

I'll try to find the battery registers

[sean89butler]

Here's all the registers I've found so far.

-OXP_SENSOR_FAN_REG: 0x76

-PWM Enable Register: 0x4A

-Fan Speed Register: 0x4B

-Bypass Power Supply: 0xA4

-Battery Charge Limit: 0xA3

Registers 0x00 and 0x01 don't change no matter what I do, they remain at 09 and 06 respectively.
