# # Video configuration # menu "Graphics support" config DM_VIDEO bool "Enable driver model support for LCD/video" depends on DM 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. config VIDEO_BPP8 bool "Support 8-bit-per-pixel displays" depends on DM_VIDEO default y if DM_VIDEO help Support drawing text and bitmaps onto a 8-bit-per-pixel display. Enabling this will include code to support this display. Without this option, such displays will not be supported and console output will be empty. config VIDEO_BPP16 bool "Support 16-bit-per-pixel displays" depends on DM_VIDEO default y if DM_VIDEO help Support drawing text and bitmaps onto a 16-bit-per-pixel display. Enabling this will include code to support this display. Without this option, such displays will not be supported and console output will be empty. config VIDEO_BPP32 bool "Support 32-bit-per-pixel displays" depends on DM_VIDEO default y if DM_VIDEO help Support drawing text and bitmaps onto a 32-bit-per-pixel display. Enabling this will include code to support this display. Without this option, such displays will not be supported and console output will be empty. config CONSOLE_NORMAL bool "Support a simple text console" depends on DM_VIDEO default y if DM_VIDEO help Support drawing text on the frame buffer console so that it can be used as a console. Rotation is not supported by this driver (see CONFIG_CONSOLE_ROTATION for that). A built-in 8x16 font is used for the display. config CONSOLE_ROTATION bool "Support rotated displays" depends on DM_VIDEO help Sometimes, for example if the display is mounted in portrait mode or even if it's mounted landscape but rotated by 180degree, we need to rotate our content of the display relative to the framebuffer, so that user can read the messages which are printed out. Enable this option to include a text driver which can support this. The rotation is set by the 'rot' parameter in struct video_priv: 0=unrotated, 1=90 degrees clockwise, 2=180 degrees, 3=270 degrees. config CONSOLE_TRUETYPE bool "Support a console that uses TrueType fonts" depends on DM_VIDEO help TrueTrype fonts can provide outline-drawing capability rather than needing to provide a bitmap for each font and size that is needed. With this option you can adjust the text size and use a variety of fonts. Note that this is noticeably slower than with normal console. config CONSOLE_TRUETYPE_SIZE int "TrueType font size" depends on CONSOLE_TRUETYPE default 18 help This sets the font size for the console. The size is measured in pixels and is the nominal height of a character. Note that fonts are commonly measured in 'points', being 1/72 inch (about 3.52mm). However that measurement depends on the size of your display and there is no standard display density. At present there is not a method to select the display's physical size, which would allow U-Boot to calculate the correct font size. source "drivers/video/fonts/Kconfig" config VIDCONSOLE_AS_LCD bool "Use 'vidconsole' when 'lcd' is seen in stdout" depends on DM_VIDEO help This is a work-around for boards which have 'lcd' in their stdout environment variable, but have moved to use driver model for video. In this case the console will no-longer work. While it is possible to update the environment, the breakage may be confusing for users. This option will be removed around the end of 2016. config VIDEO_VESA bool "Enable VESA video driver support" default n help Turn on this option to enable a very simple driver which uses vesa to discover the video mode and then provides a frame buffer for use by U-Boot. This can in principle be used with any platform that supports PCI and video cards that support VESA BIOS Extension (VBE). config FRAMEBUFFER_SET_VESA_MODE bool "Set framebuffer graphics resolution" depends on VIDEO_VESA || VIDEO_BROADWELL_IGD help Set VESA/native framebuffer mode (needed for bootsplash and graphical framebuffer console) choice prompt "framebuffer graphics resolution" default FRAMEBUFFER_VESA_MODE_117 depends on FRAMEBUFFER_SET_VESA_MODE help This option sets the resolution used for the U-Boot framebuffer (and bootsplash screen). config FRAMEBUFFER_VESA_MODE_100 bool "640x400 256-color" config FRAMEBUFFER_VESA_MODE_101 bool "640x480 256-color" config FRAMEBUFFER_VESA_MODE_102 bool "800x600 16-color" config FRAMEBUFFER_VESA_MODE_103 bool "800x600 256-color" config FRAMEBUFFER_VESA_MODE_104 bool "1024x768 16-color" config FRAMEBUFFER_VESA_MODE_105 bool "1024x768 256-color" config FRAMEBUFFER_VESA_MODE_106 bool "1280x1024 16-color" config FRAMEBUFFER_VESA_MODE_107 bool "1280x1024 256-color" config FRAMEBUFFER_VESA_MODE_108 bool "80x60 text" config FRAMEBUFFER_VESA_MODE_109 bool "132x25 text" config FRAMEBUFFER_VESA_MODE_10A bool "132x43 text" config FRAMEBUFFER_VESA_MODE_10B bool "132x50 text" config FRAMEBUFFER_VESA_MODE_10C bool "132x60 text" config FRAMEBUFFER_VESA_MODE_10D bool "320x200 32k-color (1:5:5:5)" config FRAMEBUFFER_VESA_MODE_10E bool "320x200 64k-color (5:6:5)" config FRAMEBUFFER_VESA_MODE_10F bool "320x200 16.8M-color (8:8:8)" config FRAMEBUFFER_VESA_MODE_110 bool "640x480 32k-color (1:5:5:5)" config FRAMEBUFFER_VESA_MODE_111 bool "640x480 64k-color (5:6:5)" config FRAMEBUFFER_VESA_MODE_112 bool "640x480 16.8M-color (8:8:8)" config FRAMEBUFFER_VESA_MODE_113 bool "800x600 32k-color (1:5:5:5)" config FRAMEBUFFER_VESA_MODE_114 bool "800x600 64k-color (5:6:5)" config FRAMEBUFFER_VESA_MODE_115 bool "800x600 16.8M-color (8:8:8)" config FRAMEBUFFER_VESA_MODE_116 bool "1024x768 32k-color (1:5:5:5)" config FRAMEBUFFER_VESA_MODE_117 bool "1024x768 64k-color (5:6:5)" config FRAMEBUFFER_VESA_MODE_118 bool "1024x768 16.8M-color (8:8:8)" config FRAMEBUFFER_VESA_MODE_119 bool "1280x1024 32k-color (1:5:5:5)" config FRAMEBUFFER_VESA_MODE_11A bool "1280x1024 64k-color (5:6:5)" config FRAMEBUFFER_VESA_MODE_11B bool "1280x1024 16.8M-color (8:8:8)" config FRAMEBUFFER_VESA_MODE_USER bool "Manually select VESA mode" endchoice # Map the config names to an integer (KB). config FRAMEBUFFER_VESA_MODE prompt "VESA mode" if FRAMEBUFFER_VESA_MODE_USER hex default 0x100 if FRAMEBUFFER_VESA_MODE_100 default 0x101 if FRAMEBUFFER_VESA_MODE_101 default 0x102 if FRAMEBUFFER_VESA_MODE_102 default 0x103 if FRAMEBUFFER_VESA_MODE_103 default 0x104 if FRAMEBUFFER_VESA_MODE_104 default 0x105 if FRAMEBUFFER_VESA_MODE_105 default 0x106 if FRAMEBUFFER_VESA_MODE_106 default 0x107 if FRAMEBUFFER_VESA_MODE_107 default 0x108 if FRAMEBUFFER_VESA_MODE_108 default 0x109 if FRAMEBUFFER_VESA_MODE_109 default 0x10A if FRAMEBUFFER_VESA_MODE_10A default 0x10B if FRAMEBUFFER_VESA_MODE_10B default 0x10C if FRAMEBUFFER_VESA_MODE_10C default 0x10D if FRAMEBUFFER_VESA_MODE_10D default 0x10E if FRAMEBUFFER_VESA_MODE_10E default 0x10F if FRAMEBUFFER_VESA_MODE_10F default 0x110 if FRAMEBUFFER_VESA_MODE_110 default 0x111 if FRAMEBUFFER_VESA_MODE_111 default 0x112 if FRAMEBUFFER_VESA_MODE_112 default 0x113 if FRAMEBUFFER_VESA_MODE_113 default 0x114 if FRAMEBUFFER_VESA_MODE_114 default 0x115 if FRAMEBUFFER_VESA_MODE_115 default 0x116 if FRAMEBUFFER_VESA_MODE_116 default 0x117 if FRAMEBUFFER_VESA_MODE_117 default 0x118 if FRAMEBUFFER_VESA_MODE_118 default 0x119 if FRAMEBUFFER_VESA_MODE_119 default 0x11A if FRAMEBUFFER_VESA_MODE_11A default 0x11B if FRAMEBUFFER_VESA_MODE_11B default 0x117 if FRAMEBUFFER_VESA_MODE_USER config VIDEO_LCD_ANX9804 bool "ANX9804 bridge chip" default n ---help--- Support for the ANX9804 bridge chip, which can take pixel data coming from a parallel LCD interface and translate it on the fy into a DP interface for driving eDP TFT displays.
