Laszlo,
Where do you get the video resolution list? I prefer to be more popular
to cover most common resolutions we see.
Thanks
Elvin

Subject: [edk2] [PATCH 1/1] MdeModulePkg: TerminalDxe: add other text
resolutions
When the console output is multiplexed to several devices by ConSplitterDxe,
then ConSplitterDxe builds an intersection of text modes supported by all
console output devices.
Two notable output devices are provided by:
(1) MdeModulePkg/Universal/Console/GraphicsConsoleDxe,
(2) MdeModulePkg/Universal/Console/TerminalDxe.
GraphicsConsoleDxe supports four modes at most -- see
InitializeGraphicsConsoleTextMode():
(1a) 80x25 (required by the UEFI spec as mode 0),
(1b) 80x50 (not necessarily supported, but if it is, then the UEFI spec
requires the driver to provide it as mode 1),
(1c) 100x31 (corresponding to graphics resolution 800x600, which the UEFI
spec requires from all plug-in graphics devices),
(1d) "full screen" resolution, derived form the underlying GOP's
horizontal and vertical resolutions with division by EFI_GLYPH_WIDTH
(8) and EFI_GLYPH_HEIGHT (19), respectively.
The automatic "full screen resolution" makes GraphicsConsoleDxe's character
console very flexible. However, TerminalDxe (which runs on serial ports) only
provides the following fixed resolutions -- see
InitializeTerminalConsoleTextMode():
(2a) 80x25 (required by the UEFI spec as mode 0),
(2b) 80x50 (since the character resolution of a serial device cannot be
interrogated easily, this is added unconditionally as mode 1)
(2c) modes 2 and above come from "mTerminalConsoleModeData". This table
currently only contains one mode, 100x31.
When ConSplitterDxe combines (1) and (2), multiplexing console output to both
video output and serial terminal, the list of commonly supported text modes
(ie. the "intersection") comprises:
(3a) 80x25, unconditionally, from (1a) and (2a),
(3b) 80x50, if the graphics console provides at least 640x950 pixel
resolution, from (1b) and (2b)
(3c) 100x31, if the graphics device is a plug-in one (because in that case
800x600 is a mandated pixel resolution), from (1c) and (2c).
Unfortunately, the "full screen resolution" (1d) of the GOP-based text console
is not available in general.
Mitigate this problem by extending "mTerminalConsoleModeData" with a handful of
text resolutions that are derived from widespread maximal pixel resolutions.
This way TerminalDxe won't cause ConSplitterDxe to filter out the most frequent
(1d) values from the intersection, and eg. the MODE command in the UEFI shell
will offer the "best" (ie. full screen) resolution too.
