Subject: [PATCH] EFI: console: Fix the "enter" key not working on X86 tablets
|
|
|
|
Most 8" or 7" x86 Windows 10 tablets come with volume up/down buttons and
|
|
a power-button. In their UEFI these are almost always mapped to arrow
|
|
up/down and enter.
|
|
|
|
Pressing the volume buttons (sometimes by accident) will stop the
|
|
menu countdown, but the power-button / "enter" key was not being recognized
|
|
as enter, so the user would be stuck at the grub menu.
|
|
|
|
The problem is that these tablets send scan_code 13 or 0x0d for the
|
|
power-button, which officialy maps to the F3 key. They also set
|
|
unicode_char to 0x0d.
|
|
|
|
This commit recognizes the special case of both scan_code and unicode_char
|
|
being set to 0x0d and treats this as an enter key press.
|
|
|
|
This fixes things getting stuck at the grub-menu and allows the user
|
|
to choice a grub-menu entry using the buttons on the tablet.
|
