Hi x86 platform list,
I'm considering contributing support for the usage mode/tablet mode
switch for some Lenovo laptops (including the popular IdeaPad Flex
series).
There is already an out-of-tree driver at
https://github.com/lukas-w/yoga-usage-mode which works well,
but I'd like to get this support upstream.
I have a few questions regarding the best approach:
1. There is the ideapad-laptop module already which deals with a bunch
of functionality related to these laptops, but not the mode switch. Do
you prefer a separate driver or should the functionality be added to
ideapad-laptop?
2. The existing out-of-tree driver uses a WMI interface to access mode
information. Should I work on the WMI layer or should I figure out
which EC registers to use to get the functionality independently? If
yes, how do we want to identify support for this type of mode switch?
Regards,
Lorenz
