12 | a bitmap display of various sizes and depths which can be drawn on | |

14 | option compiles in the video uclass and routes all LCD/video access | |

70 | help |
71 | Generally, video drivers request the amount of memory they need for | |
72 | the frame buffer when they are bound, by setting the size field in | |
196947b1 | 73 | struct video_uc_plat. That memory is then reserved for use after |
551ca0e6 SG |
74 | relocation. But PCI drivers cannot be bound before relocation unless |
75 | they are mentioned in the devicetree. | |
76 | ||
77 | With this value set appropriately, it is possible for PCI video | |
78 | devices to have a framebuffer allocated by U-Boot. | |
79 | ||
80 | Note: the framebuffer needs to be large enough to store all pixels at | |
17cd8023 | 81 | maximum resolution. For example, at 2560 x 1600 with 32 bits per |
551ca0e6 SG |
82 | pixel, 2560 * 1600 * 32 / 8 = 0xfa0000 bytes are needed. |

86 | help |
87 | On some machines (e.g. x86), reading from the frame buffer is very | |

89 | allows the frame buffer to be kept in cached memory (allocated by | |
90 | U-Boot) and then copied to the hardware frame-buffer as needed. | |
91 | ||
92 | To use this, your video driver must set @copy_base in | |
196947b1 | 93 | struct video_uc_plat. |
