Subject: 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() and "mGraphicsConsoleModeData":
|
|
|
|
(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() and "mTerminalConsoleModeData":
|
|
|
|
(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) 100x31 (since the character resolution of a serial device cannot be
|
|
interrogated easily, this is added unconditionally as mode 2).
|
|
|
|
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.
|
|
|
|
Upstream status: three calendar months (with on-and-off discussion and
|
|
patches) have not been enough to find a solution to this problem that
|
|
would please all stakeholders.

Notes about the 20160608b-988715a -> 20170228-c325e41585e3 rebase:
|
|
|
|
- adapt commit 0bc77c63de03 (code and commit message) to upstream commit
|
|
390b95a49c14 ("MdeModulePkg/TerminalDxe: Refine
|
|
InitializeTerminalConsoleTextMode", 2017-01-10).
