Hey,
I wonder if it would be possible to implement a write to / dump EC register mechanism into HwInfo? I am actually trying to find a way to deactivate EC fan control and let HwInfo control the fans, for the Dell XPS 15 9570. Sending values to the fans works with HwInfo, but the EC overwrites them immediately again. Found some information on the web, that there is a way to set a register at least for 9550/9560 deactivating the EC fan control
[font=arial, helvetica, sans-serif]#define DISABLE_BIOS_METHOD2 0x34a3[/font]
[font=arial, helvetica, sans-serif]#define ENABLE_BIOS_METHOD2 0x35a3[/font]
I found these two implementations, one SMM Windows driver port, which is based on the Linux i8k driver or something I think? But it fails to load for the 9570
https://github.com/424778940z/bzh-windrv-dell-smm-io
and this one which basically also uses the same registers

[font=arial, helvetica, sans-serif]Would this be possible to implement in HwInfo? How far implemented is the EC/SMM driver for Dell Laptops in HwInfo?[/font]
