EmbeddedPkg: Clear keyboard queue buffer after reading

2025-10-09T08:02:51+00:00

There is a possibility to retrieve user input keystroke data stored in the queue buffer via the EFI_SIMPLE_TEXT_INPUT_PROTOCOL pointer. To prevent exposure of the password string, clear the queue buffer by filling it with zeros after reading. Signed-off-by: Nick Wang

EmbeddedPkg/VirtualKeyboard: Avoid notification called more than once

2018-09-14T02:18:31+00:00

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=996 Issue: In current code logic, when a key is pressed, it will search the whole NotifyList to find whether a notification has been registered with the keystroke. if yes, it will en-queue the key for notification execution later. And now if different notification functions have been registered with the same key, then the key will be en-queued more than once. Then it will cause the notification executed more than once. This patch is to enhance the code logic to fix this issue.

EmbeddedPkg/Drivers: add virtual keyboard driver

2018-04-30T16:58:14+00:00

This driver is used to simulate a keyboard. For example, user could read GPIO setting or data from RAM address. If the value matches the expected pattern, it could trigger a key pressed event. User needs to implement hooks of PLATFORM_VIRTUAL_KBD_PROTOCOL. There're 4 hooks in this protocol. Register(): Quote the interface that user needs. For example, user needs to locate GPIO protocol if he wants to simulate a GPIO value as a key. Reset(): Do the initialization before reading value. Query(): Read value. If the value matches the expected pattern, trigger a key pressed event. Clear(): Clean the value if necessary.
