Subject: [PATCH] EFI: console: Implement getkeystatus() support
|
|
|
|
Implement getkeystatus() support.
|
|
|
|
Note that if a non-modifier key gets pressed and repeated calls to
|
|
getkeystatus() are made then it will return the modifier status at the
|
|
time of the non-modifier key, until that key-press gets consumed by a
|
|
getkey() call.
|
|
|
|
This is a side-effect of how the EFI simple-text-input protocol works
|
|
and cannot be avoided.
