Fan	Address	Value	State	Comment
Real-Time fan speed	0xCD			Weird behavior: gradually increasing the RPM starting at the lowest speed (1500 RPM = 0x3A) then the hexa value decreases and cross 0x00, loops around at 0xFF, at 3000 RPM = 0xA0 and finally max at 5925 RPM = 0x51

About realtime fan speed - actually it seems using 2 bytes, and values is X / RPM

Does writing keyboard brightness to EC change backlight brightness?

Win-Fn swap

Known issue

[smalltheif]

After closer inspection, I identified the byte corresponding to the keyboard backlight intensity. I modified the address and verified the correct functioning.

Do you know what are these 2 bytes? I don't understand what X / RPM means.

Win-Fn swap

This issue seems to have been resolved in the main branch, do I correct my version of the branch, by adding .invert = true?

yes, but for now just use mcontrol center if you want realtime rpm

This issue seems to have been resolved in the main branch, do I correct my version of the branch, by adding .invert = true?

Yes, please do this

Also, you can merge main to your branch if you know how to do it. Else, just add this option.

.invert  = true

[smalltheif]

Everything should be OK to merge.

On a side note: adding support for the keyboard backlight intensity enabled its control in the quick settings in Gnome 46 on Fedora 40 (Workstation Edition).

Wow, that's good, because on older gnomes you need to install external plugin

Hi!

after each reboot, the shift mode is back to unspecified

That's normal, it happens on all laptops. You can mark is as supported

Edit: actually, I'll just commit it myself. I'm merging multiple PRs right now, don't wan't to cause more conflicts
