8 bool "Enable driver model support for LCD/video"
11 This enables driver model for LCD and video devices. These support
12 a bitmap display of various sizes and depths which can be drawn on
13 to display a command-line console or splash screen. Enabling this
14 option compiles in the video uclass and routes all LCD/video access
18 bool "Generic PWM based Backlight Driver"
19 depends on DM_VIDEO && DM_PWM
22 If you have a LCD backlight adjustable by PWM, say Y to enable
24 This driver can be use with "simple-panel" and
25 it understands the standard device tree

34 This driver can be used with "simple-panel" and
35 it understands the standard device tree

39 bool "Support 8-bit-per-pixel displays"
43 Support drawing text and bitmaps onto a 8-bit-per-pixel display.
44 Enabling this will include code to support this display. Without
45 this option, such displays will not be supported and console output
49 bool "Support 16-bit-per-pixel displays"
53 Support drawing text and bitmaps onto a 16-bit-per-pixel display.
54 Enabling this will include code to support this display. Without
55 this option, such displays will not be supported and console output
59 bool "Support 32-bit-per-pixel displays"
63 Support drawing text and bitmaps onto a 32-bit-per-pixel display.
64 Enabling this will include code to support this display. Without
65 this option, such displays will not be supported and console output
69 bool "Support ANSI escape sequences in video console"
73 Enable ANSI escape sequence decoding for a more fully functional
77 bool "Support a simple text console"
81 Support drawing text on the frame buffer console so that it can be
82 used as a console. Rotation is not supported by this driver (see
83 CONFIG_CONSOLE_ROTATION for that). A built-in 8x16 font is used
86 config CONSOLE_ROTATION
87 bool "Support rotated displays"
90 Sometimes, for example if the display is mounted in portrait
91 mode or even if it's mounted landscape but rotated by 180degree,
92 we need to rotate our content of the display relative to the
93 framebuffer, so that user can read the messages which are
94 printed out. Enable this option to include a text driver which can
95 support this. The rotation is set by the 'rot' parameter in
96 struct video_priv: 0=unrotated, 1=90 degrees clockwise, 2=180
97 degrees, 3=270 degrees.
99 config CONSOLE_TRUETYPE
100 bool "Support a console that uses TrueType fonts"
103 TrueTrype fonts can provide outline-drawing capability rather than
104 needing to provide a bitmap for each font and size that is needed.
105 With this option you can adjust the text size and use a variety of
106 fonts. Note that this is noticeably slower than with normal console.
108 config CONSOLE_TRUETYPE_SIZE
109 int "TrueType font size"
110 depends on CONSOLE_TRUETYPE
113 This sets the font size for the console. The size is measured in
114 pixels and is the nominal height of a character. Note that fonts
115 are commonly measured in 'points', being 1/72 inch (about 3.52mm).
116 However that measurement depends on the size of your display and
117 there is no standard display density. At present there is not a
118 method to select the display's physical size, which would allow
119 U-Boot to calculate the correct font size.
121 config SYS_WHITE_ON_BLACK
122 bool "Display console as white on a black background"
123 default y if ARCH_AT91 || ARCH_EXYNOS || ARCH_ROCKCHIP || TEGRA || X86 || ARCH_SUNXI
125 Normally the display is black on a white background, Enable this
126 option to invert this, i.e. white on a black background. This can be
127 better in low-light situations or to reduce eye strain in some
131 bool "Skip framebuffer clear"
133 If firmware (whatever loads u-boot) has already put a splash image
134 on screen, you might want to preserve it until whatever u-boot
135 loads takes over the screen. This, for example, can be used to
136 keep splash image on screen until grub graphical boot menu starts.
138 source "drivers/video/fonts/Kconfig"
140 config VIDCONSOLE_AS_LCD
141 bool "Use 'vidconsole' when 'lcd' is seen in stdout"
144 This is a work-around for boards which have 'lcd' in their stdout
145 environment variable, but have moved to use driver model for video.
146 In this case the console will no-longer work. While it is possible
147 to update the environment, the breakage may be confusing for users.
148 This option will be removed around the end of 2016.
150 config VIDEO_COREBOOT
151 bool "Enable coreboot framebuffer driver support"
152 depends on X86 && SYS_COREBOOT
154 Turn on this option to enable a framebuffer driver when U-Boot is
155 loaded by coreboot where the graphics device is configured by
156 coreboot already. This can in principle be used with any platform
157 that coreboot supports.
160 bool "Enable EFI framebuffer driver support"
163 Turn on this option to enable a framebuffeer driver when U-Boot is
164 loaded as a payload (see README.u-boot_on_efi) by an EFI BIOS where
165 the graphics device is configured by the EFI BIOS already. This can
166 in principle be used with any platform that has an EFI BIOS.
169 bool "Enable VESA video driver support"
172 Turn on this option to enable a very simple driver which uses vesa
173 to discover the video mode and then provides a frame buffer for use
174 by U-Boot. This can in principle be used with any platform that
175 supports PCI and video cards that support VESA BIOS Extension (VBE).

689 Enables a simple generic display driver which utilizes the
