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

35 it understands the standard device tree

39 bool "Enable vidconsole commands lcdputs and setcurs"
43 Enabling this will provide 'setcurs' and 'lcdputs' commands which
44 support cursor positioning and drawing strings on video framebuffer.
47 bool "Support 8-bit-per-pixel displays"
51 Support drawing text and bitmaps onto a 8-bit-per-pixel display.
52 Enabling this will include code to support this display. Without
53 this option, such displays will not be supported and console output
57 bool "Support 16-bit-per-pixel displays"
61 Support drawing text and bitmaps onto a 16-bit-per-pixel display.
62 Enabling this will include code to support this display. Without
63 this option, such displays will not be supported and console output
67 bool "Support 32-bit-per-pixel displays"
71 Support drawing text and bitmaps onto a 32-bit-per-pixel display.
72 Enabling this will include code to support this display. Without
73 this option, such displays will not be supported and console output
77 bool "Support ANSI escape sequences in video console"
81 Enable ANSI escape sequence decoding for a more fully functional
85 bool "Support MIPI DSI interface"
88 Support MIPI DSI interface for driving a MIPI compatible device.
89 The MIPI Display Serial Interface (MIPI DSI) defines a high-speed
90 serial interface between a host processor and a display module.
93 bool "Support a simple text console"
97 Support drawing text on the frame buffer console so that it can be
98 used as a console. Rotation is not supported by this driver (see
99 CONFIG_CONSOLE_ROTATION for that). A built-in 8x16 font is used
102 config CONSOLE_ROTATION
103 bool "Support rotated displays"
106 Sometimes, for example if the display is mounted in portrait
107 mode or even if it's mounted landscape but rotated by 180degree,
108 we need to rotate our content of the display relative to the
109 framebuffer, so that user can read the messages which are
110 printed out. Enable this option to include a text driver which can
111 support this. The rotation is set by the 'rot' parameter in
112 struct video_priv: 0=unrotated, 1=90 degrees clockwise, 2=180
113 degrees, 3=270 degrees.
115 config CONSOLE_TRUETYPE
116 bool "Support a console that uses TrueType fonts"
119 TrueTrype fonts can provide outline-drawing capability rather than
120 needing to provide a bitmap for each font and size that is needed.
121 With this option you can adjust the text size and use a variety of
122 fonts. Note that this is noticeably slower than with normal console.
124 config CONSOLE_TRUETYPE_SIZE
125 int "TrueType font size"
126 depends on CONSOLE_TRUETYPE
129 This sets the font size for the console. The size is measured in
130 pixels and is the nominal height of a character. Note that fonts
131 are commonly measured in 'points', being 1/72 inch (about 3.52mm).
132 However that measurement depends on the size of your display and
133 there is no standard display density. At present there is not a
134 method to select the display's physical size, which would allow
135 U-Boot to calculate the correct font size.

138 bool "Display console as white on a black background"
139 default y if ARCH_AT91 || ARCH_EXYNOS || ARCH_ROCKCHIP || ARCH_TEGRA || X86 || ARCH_SUNXI
141 Normally the display is black on a white background, Enable this
142 option to invert this, i.e. white on a black background. This can be
143 better in low-light situations or to reduce eye strain in some
147 bool "Skip framebuffer clear"
149 If firmware (whatever loads u-boot) has already put a splash image
150 on screen, you might want to preserve it until whatever u-boot
151 loads takes over the screen. This, for example, can be used to
152 keep splash image on screen until grub graphical boot menu starts.

156 config VIDCONSOLE_AS_LCD
157 bool "Use 'vidconsole' when 'lcd' is seen in stdout"
160 This is a work-around for boards which have 'lcd' in their stdout
161 environment variable, but have moved to use driver model for video.
162 In this case the console will no-longer work. While it is possible
163 to update the environment, the breakage may be confusing for users.
164 This option will be removed around the end of 2016.
166 config VIDEO_COREBOOT
167 bool "Enable coreboot framebuffer driver support"
168 depends on X86 && SYS_COREBOOT
170 Turn on this option to enable a framebuffer driver when U-Boot is
171 loaded by coreboot where the graphics device is configured by
172 coreboot already. This can in principle be used with any platform
173 that coreboot supports.
176 bool "Enable EFI framebuffer driver support"
179 Turn on this option to enable a framebuffeer driver when U-Boot is
180 loaded as a payload (see README.u-boot_on_efi) by an EFI BIOS where
181 the graphics device is configured by the EFI BIOS already. This can
182 in principle be used with any platform that has an EFI BIOS.
185 bool "Enable VESA video driver support"
188 Turn on this option to enable a very simple driver which uses vesa
189 to discover the video mode and then provides a frame buffer for use
190 by U-Boot. This can in principle be used with any platform that
191 supports PCI and video cards that support VESA BIOS Extension (VBE).

698 Defines the foreground colour for the console. The value is from
699 0x00 to 0xff and the meaning depends on the graphics card.
700 Typically, 0x00 means black and 0xff means white. Do not set
701 the background and foreground to the same colour or you will see
705 bool "Enable legacy LCD support"
707 Define this to enable LCD support (for output to LCD display).
708 You will also need to select an LCD driver using an additional
709 CONFIG option. See the README for details. Drives which have been
710 converted to driver model will instead used CONFIG_DM_VIDEO.
715 Enables the common driver code for the Designware HDMI TX
716 block found in SoCs from various vendors.
717 As this does not provide any functionality by itself (but
718 rather requires a SoC-specific glue driver to call it), it
719 can not be enabled from the configuration menu.
721 config VIDEO_DSI_HOST_SANDBOX
722 bool "Enable sandbox for dsi host"
724 select VIDEO_MIPI_DSI
726 Enable support for sandbox dsi host device used for testing
728 Display Serial Interface (DSI) defines a serial bus and
729 a communication protocol between the host and the device
732 config VIDEO_DW_MIPI_DSI
734 select VIDEO_MIPI_DSI
736 Enables the common driver code for the Synopsis Designware
737 MIPI DSI block found in SoCs from various vendors.
738 As this does not provide any functionality by itself (but
739 rather requires a SoC-specific glue driver to call it), it
740 can not be enabled from the configuration menu.
743 bool "Simple display driver for preconfigured display"
745 Enables a simple generic display driver which utilizes the
746 simple-framebuffer devicetree bindings.
748 This driver assumes that the display hardware has been initialized
749 before u-boot starts, and u-boot will simply render to the pre-
750 allocated frame buffer surface.
752 config VIDEO_DT_SIMPLEFB
753 bool "Enable SimpleFB support for passing framebuffer to OS"
755 Enables the code to pass the framebuffer to the kernel as a
756 simple framebuffer in the device tree.
757 The video output is initialized by U-Boot, and kept by the
761 bool "Enable OSD support"
765 This supports drivers that provide a OSD (on-screen display), which
766 is a (usually text-oriented) graphics buffer to show information on
770 bool "Enable sandbox OSD"
773 Enable support for sandbox OSD device used for testing purposes.
776 bool "Enable IHS video out driver"
779 Enable support for the gdsys Integrated Hardware Systems (IHS) video
780 out On-screen Display (OSD) used on gdsys FPGAs to control dynamic
781 textual overlays of the display outputs.
