Dear all, I'd like to have tablet mode support on my system, probably by means an linux input device such as implemented in the intel platform specific driver drivers/platform/x86/intel/vbtn.c [0] In the end I hope GNOME eventually to rotate the systems display and to show some virtual keyboard (upon users request), cf. for [3] It appears there has already been a patch proposed by the chromium team to support device PNP0C60 [1] but not merged to [5]. Since the system of interest is a HP Probook, there is already a driver providing virtual buttons,namely hp-wmi [6]. However, the driver loads probes and loads successfully but doesn't provide any additional functionality plus some non critical errors on incorrect ACPI method calls. I've noticed AMD has started to provide platform specific driver(s) such as pmf [2]. To my knowledge there is no support for CEZANNE/green sardine based systems (yet). What would be recommended practice and subsystem/folder to provide such capability by means of a (platform specific) driver? At least the CID PNP0C60 seems to be held by Microsoft [4] and thus be common to both amd and intel platforms [4]. However, HID INT33D6 is held by Intel and HID AMDI0081 by AMD. Yet I'm not quite sure if iio-sensor-proxy [7] needs to be involved, too.
