That memory is then reserved for use after 80 relocation. But PCI drivers cannot be bound before relocation unless 81 they are mentioned in the devicetree. 82 83 With this value set appropriately, it is possible for PCI video 84 devices to have a framebuffer allocated by U-Boot. 85 86 Note: the framebuffer needs to be large enough to store all pixels at 87 maximum resolution.

To make the display controller pick up screen updates, we 109 have to flush frame buffer contents from CPU caches into RAM which 110 can be a slow operation. 111 112 This feature adds damage tracking to collect information about regions 113 that received updates. When we want to sync, we then only flush 114 regions of the frame buffer that were modified before, speeding up 115 screen refreshes significantly. 116 117 It is also used by VIDEO_COPY to identify which regions changed. 118 119config BACKLIGHT_PWM 120 bool "Generic PWM based Backlight Driver" 121 depends on BACKLIGHT && DM_PWM 122 default y 123 help 124 If you have a LCD backlight adjustable by PWM, say Y to enable 125 this driver. 126 This driver can be use with "simple-panel" and 127 it understands the standard device tree 128 (leds/backlight/pwm-backlight.txt) 129 130config BACKLIGHT_GPIO 131 bool "Generic GPIO based Backlight Driver" 132 depends on BACKLIGHT 133 help 134 If you have a LCD backlight adjustable by GPIO, say Y to enable 135 this driver. 136 This driver can be used with "simple-panel" and 137 it understands the standard device tree 138 (leds/backlight/gpio-backlight.txt) 139 140config VIDEO_BPP8 141 bool "Support 8-bit-per-pixel displays" 142 default y 143 help 144 Support drawing text and bitmaps onto a 8-bit-per-pixel display. 145 Enabling this will include code to support this display.

Note that the time between video syncs 266 may be longer than this, since syncs only happen when the video system 267 is used, e.g. by outputting a character to the console. 268 269 It may also be shorter, since the video uclass will automatically 270 force a sync in certain situations. 271 272 Many video-output systems require a sync operation before any output 273 is visible.
