That memory is then reserved for use after 73 relocation. But PCI drivers cannot be bound before relocation unless 74 they are mentioned in the devicetree. 75 76 With this value set appropriately, it is possible for PCI video 77 devices to have a framebuffer allocated by U-Boot. 78 79 Note: the framebuffer needs to be large enough to store all pixels at 80 maximum resolution. For example, at 1920 x 1200 with 32 bits per 81 pixel, 2560 * 1600 * 32 / 8 = 0xfa0000 bytes are needed. 82 83config VIDEO_COPY 84 bool "Enable copying the frame buffer to a hardware copy" 85 help 86 On some machines (e.g. x86), reading from the frame buffer is very 87 slow because it is uncached. To improve performance, this feature 88 allows the frame buffer to be kept in cached memory (allocated by 89 U-Boot) and then copied to the hardware frame-buffer as needed. 90 91 To use this, your video driver must set @copy_base in 92 struct video_uc_plat. 93 94config BACKLIGHT_PWM 95 bool "Generic PWM based Backlight Driver" 96 depends on BACKLIGHT && DM_PWM 97 default y 98 help 99 If you have a LCD backlight adjustable by PWM, say Y to enable 100 this driver. 101 This driver can be use with "simple-panel" and 102 it understands the standard device tree 103 (leds/backlight/pwm-backlight.txt) 104 105config BACKLIGHT_GPIO 106 bool "Generic GPIO based Backlight Driver" 107 depends on BACKLIGHT 108 help 109 If you have a LCD backlight adjustable by GPIO, say Y to enable 110 this driver. 111 This driver can be used with "simple-panel" and 112 it understands the standard device tree 113 (leds/backlight/gpio-backlight.txt) 114 115config VIDEO_BPP8 116 bool "Support 8-bit-per-pixel displays" 117 default y 118 help 119 Support drawing text and bitmaps onto a 8-bit-per-pixel display. 120 Enabling this will include code to support this display.

The size is measured in 195 pixels and is the nominal height of a character. Note that fonts 196 are commonly measured in 'points', being 1/72 inch (about 3.52mm). 197 However that measurement depends on the size of your display and 198 there is no standard display density.

When 210 boot menus are in use, this may need to be increased. 211 212 Note that a separate entry is needed for each font size, even if the 213 font itself is the same. This is because the entry caches various 214 font metrics which are expensive to regenerate each time the font 215 size changes. 216 217config SYS_WHITE_ON_BLACK 218 bool "Display console as white on a black background" 219 default y if ARCH_AT91 || ARCH_EXYNOS || ARCH_ROCKCHIP || ARCH_TEGRA || X86 || ARCH_SUNXI 220 help 221 Normally the display is black on a white background, Enable this 222 option to invert this, i.e. white on a black background.
