[SOLVED] Thinkpad ACPI Extras is not in 6.18 anymore?

[cz0]

Hi folks!

After updating to 6.18.18 I found that my Lenovo X230 has no ACPI support: no AC/battery status, no brightness key support, no sensors, no lid events.
After some search I found that CONFIG_THINKPAD_ACPI* options are completely missing from 6.18.18 kernel and Device drivers -> X86 Platform Specific Device Drivers simply do not mention any Thinkpad option except hdaps. There is whole bunch of vendor Laptop Extras except for Thinkpad! Also I found Lenovo IdeaPad Laptop Extras but that didn't work. Google gives only old information that does not help. I have to roll back to 6.12.58.

What is going on? What I'm missing?

I found it right below the Ideapad Laptop Extras:

Code: Select all

< >   Lenovo IdeaPad Laptop Extras
< >   Lenovo Hotkey Utility WMI extras driver  
< >   Lenovo WMI Camera Button driver  
< >   ThinkPad ACPI Laptop Extras

It is dependent on some things. Maybe you have one of them disabled?

Yes, this was CONFIG_ACPI_EC right away. Have no clue why I disabled this, but after reenabling it, I have all ThinkPad bells and whistles back again.
Thank you very much!
