Hello, I'm interested in detecting tablet mode switching for my Lenovo Yoga laptop properly in the kernel. Ultimately I'd like to provide the SW_TABLET_MODE input event. I have found that there are ACPI events fired when the tablet mode is toggled (both directions send the same event). Here are the logs: kernel: ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PC00.LPCB.EC0._Q44.WM00], AE_NOT_FOUND (20221020/psargs-330) kernel: ACPI Error: Aborting method \_SB.PC00.LPCB.EC0._Q44 due to previous error (AE_NOT_FOUND) (20221020/psparse-529) root[10258]: ACPI group/action undefined: 06129D99-6083- / 000000d0 When I looked at the code I found TP_HKEY_EV_TABLET_CHANGED in the thinkpad_acpi.c driver which seems to have exactly the behavior I'm looking for but with a different ACPI event number. Would it be possible to do something like this in the ideapad_laptop driver?
