2025-08-22MdeModulePkg: Improve the implementation of EFI_SIMPLE_TEXT_OUTPUT_PROTOCOLGao Qihang1-0/+9
Fix TestString() to be compatible with wide/narrow string in GraphicsConsole driver. If WIDE_CHAR or NARROW_CHAR is hit in TestString function, ignore it since OutputString function will correctly handle it. Fix OutputString() to skip wide/narrow char in TerminalDxe. Because they are not displayable in terminal emulation tool, ingore to output if they are hit in OutputString function. Signed-off-by: Gao Qihang <gaoqihang@loongson.cn>

The Universal Graphics Adapter (UGA) is a graphic abstraction. The UGA I/O and Draw protocols are deprecated since UEFI 2.0 was introduced.

2022-04-22MdeModulePkg/GraphicsConsoleDxe: add modesGerd Hoffmann1-1/+4
Add modes for a few common display resolutions higher than 800x600, specifically 1024x768, 1280x800 and 1920x1080, so ConSplitterDxe has more options available. The mode list is not use as-is, InitializeGraphicsConsoleTextMode() will check the list and filter out any modes which don't fit to the screen, so this will also work fine for small displays.

REF: https://github.com/pftf/RPi4/issues/115 GraphicsConsoleDxe defaults the ConOut Mode.CursorVisible to TRUE. However, the driver never draws the cursor during init. This results in the first call to disable the cursor (using ConOut->EnableCursor(FALSE)) to actually draw the cursor on the screen, as the logic in FlushCursor depends on the Mode.CursorVisible state to determine if it should draw or erase the cursor. Fix by changing the default CursorVisible in this driver to FALSE.

2019-06-13MdeModulePkg/GraphicsConsoleDxe: Initialize the output modeZhichao Gao1-10/+32
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1412 Original logic: Connect the graphics device -> connect it as graphics consoles and initialize its parameters(Mode = -1, invalid) -> connect it as console spliter and add the device to the list(use SetMode to set mode to the user defined mode or the best mode the devices supported if the mode is invalid. *clear the screen at this phase*) Changed logic: Connect the graphics device -> connect it as graphics consoles and initialize its parameters(initialize the mode to the user defined mode or the best mode. *directly set the mode value without using SetMode, that would not clear the screen) -> connect it as console spliter and add the device to the list(use SetMode to set mode to the user defined mode or the best mode the devices supported if the mode is invalid. *now the mode is already set, so it would not clear the screen*). Also remove the section of SetMode for debug version. Impact: as the text mode may not be an invalid value, the SetMode may have no chance to be called during reconnect the graphics device. That means the screen may not be cleaned after finishing reconnect operation. There is one common condition: shell command "recoonect -r".
