| help | |
| This enables driver model for LCD and video devices. These support | |
| a bitmap display of various sizes and depths which can be drawn on | |
| to display a command-line console or splash screen. Enabling this | |
| option compiles in the video uclass and routes all LCD/video access | |
| through this. | |
| If CYCLIC is enabled (which it is by default), the cyclic subsystem | |
| is used to flush pending output to the display periodically, rather | |
| than this happening with every chunk of output. This allows for more | |
| efficient operation and faster display output. | |

| help | |
| Generally, video drivers request the amount of memory they need for | |
| the frame buffer when they are bound, by setting the size field in | |
| struct video_uc_plat. That memory is then reserved for use after | |
| relocation. But PCI drivers cannot be bound before relocation unless | |
| they are mentioned in the devicetree. | |
| With this value set appropriately, it is possible for PCI video | |
| devices to have a framebuffer allocated by U-Boot. | |
| Note: the framebuffer needs to be large enough to store all pixels at | |
| maximum resolution. For example, at 2560 x 1600 with 32 bits per | |
| pixel, 2560 * 1600 * 32 / 8 = 0xfa0000 bytes are needed. | |
| config VIDEO_COPY | |
| bool "Enable copying the frame buffer to a hardware copy" | |
| help | |
| On some machines (e.g. x86), reading from the frame buffer is very | |
| slow because it is uncached. To improve performance, this feature | |
| allows the frame buffer to be kept in cached memory (allocated by | |
| U-Boot) and then copied to the hardware frame-buffer as needed. | |
| To use this, your video driver must set @copy_base in | |
| struct video_uc_plat. | |

| This sets the font size for the console. The size is measured in | |

| are commonly measured in 'points', being 1/72 inch (about 3.52mm). | |
| However that measurement depends on the size of your display and | |

| default 100 | |
| help | |
| This sets the requested, maximum time before a video sync will take | |
| place, in milliseconds. Note that the time between video syncs | |
| may be longer than this, since syncs only happen when the video system | |
| is used, e.g. by outputting a character to the console. | |
| It may also be shorter, since the video uclass will automatically | |
| force a sync in certain situations. | |
| Many video-output systems require a sync operation before any output | |
| is visible. This may flush the CPU cache or perhaps copy the | |
| display contents to a hardware framebuffer. Without this, change to | |
