Till end of month two Dell kernel devs are on vacation, so after that they maybe answer to question about new hotkey format/support in kernel. > drivers/platform/x86/dell-wmi.c | 9 ++++++++- > 1 file changed, 8 insertions(+), 1 deletion(-) > > diff --git a/drivers/platform/x86/dell-wmi.c b/drivers/platform/x86/dell-wmi.c > index 8cb0f57..e68ce3b 100644 > --- a/drivers/platform/x86/dell-wmi.c > +++ b/drivers/platform/x86/dell-wmi.c > @@ -44,6 +44,10 @@ MODULE_LICENSE("GPL"); > #define DELL_EVENT_GUID "9DBB5994-A997-11DA-B012-B622A1EF5492" > > static int acpi_video; > +static bool process_dil; > + > +module_param(process_dil, bool, 0644); > +MODULE_PARM_DESC(process_dil, "Generate an input event when the WMI event for Dell Instant Launch hotkey is received"); I do not like name "dil". It takes me few minutes to interpret it as Dell Instant Launch...
