video: console: truetype: Staticize and constify driver ops

2026-05-29T23:10:46Z

Set the ops structure as static const. The structure is not accessible from outside of this driver and is not going to be modified at runtime. Signed-off-by: Marek Vasut Reviewed-by: Simon Glass

video: add DejaVu Mono font

2026-01-24T16:01:22Z

A TrueType font for U-Boot should fulfill the following requirements: * mono spaced * support full code page 437 * easily readable Unfortunately none of the fonts provided with U-Boot fulfills all of these requirements. Let's add the DejaVu Mono font. To reduce the code size the characters are limited to code page 437. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

vidconsole: Avoid kerning against an unrelated character

2025-05-02T19:40:25Z

When the cursor position changes, kerning should not be used for the next character, since it can make the first displayed character shuffle left or right a bit. Clear the kern character when setting the position. Signed-off-by: Simon Glass

video: truetype: Support a limit on the width of a line

2025-05-02T19:40:25Z

Expo needs to be able to word-wrap lines so that they are displayed as the user expects. Add a limit on the width of each line and support this in the measurement algorithm. Add a log category to truetype while we are here. Signed-off-by: Simon Glass

video: truetype: Support newlines in the measured string

2025-05-02T19:40:25Z

It is useful to be able to embed newline characters in the string and have the text measured into multiple lines. Add support for this. Signed-off-by: Simon Glass

video: truetype: Fill in the measured line

2025-05-02T19:40:25Z

Create a measured line for the (single) line of text. Signed-off-by: Simon Glass

video: Begin support for measuring multiple lines of text

2025-05-02T19:40:25Z

Update the vidconsole API so that measure() can measure multiple lines of text. This will make it easier to implement multi-line fields in expo. Tidy up the function comments while we are here. Signed-off-by: Simon Glass

video: Use VIDEO_DAMAGE for VIDEO_COPY

2025-05-01T10:32:45Z

CONFIG_VIDEO_COPY implemented a range-based copying mechanism: If we print a single character, it will always copy the full range of bytes from the top left corner of the character to the lower right onto the uncached frame buffer. This includes pretty much the full line contents of the printed character. Since we now have proper damage tracking, let's make use of that to reduce the amount of data we need to copy. With this patch applied, we will only copy the tiny rectangle surrounding characters when we print them, speeding up the video console. After this, changes to the main frame buffer are not immediately copied to the copy frame buffer, but postponed until the next video device sync. So issue an explicit sync before inspecting the copy frame buffer contents for the video tests.

vidconsole: Add damage notifications to all vidconsole drivers

Now that we have a damage tracking API, let's populate damage done by vidconsole drivers. We try to declare as little memory as damaged as possible.
