CONFIG_FB_TILEBLITTING: Enable Tile Blitting Support

General informations

The Linux kernel configuration item CONFIG_FB_TILEBLITTING has multiple definitions:

Enable Tile Blitting Support found in drivers/video/fbdev/core/Kconfig

The configuration item CONFIG_FB_TILEBLITTING:

• prompt: Enable Tile Blitting Support
• type: bool
• depends on: CONFIG_FB
• defined in drivers/video/fbdev/core/Kconfig
• found in Linux kernels: 6.6–6.12, 6.13-rc+HEAD

This enables tile blitting. Tile blitting is a drawing technique where the screen is divided into rectangular sections (tiles), whereas the standard blitting divides the screen into pixels. Because the default drawing element is a tile, drawing functions will be passed parameters in terms of number of tiles instead of number of pixels. For example, to draw a single character, instead of using bitmaps, an index to an array of bitmaps will be used. To clear or move a rectangular section of a screen, the rectangle will be described in terms of number of tiles in the x- and y-axis.

This is particularly important to one driver, matroxfb. If unsure, say N.
