|
|
*
|
|
* Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
|
|
*
|
|
* At the moment only the 8x16 font is tested and the font fore- and
|
|
* background color is limited to black/white/gray colors. The Linux
|
|
* logo can be placed in the upper left corner and additional board
|
|
* information strings (that normally goes to serial port) can be drawn.
|
|
*
|
|
* The console driver can use a keyboard interface for character input
|
|
* but this is deprecated. Only rk51 uses it.
|
|
*
|
|
* Character output goes to a memory-mapped video
|
|
* framebuffer with little or big-endian organisation.
|
|
* With environment setting 'console=serial' the console i/o can be
|
|
* forced to serial port.
|
|
*
|
|
* The driver uses graphic specific defines/parameters/functions:
|
|
*
|
|
* (for SMI LynxE graphic chip)
|
|
*
|
|
* VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian
|
|
* VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill
|
|
* VIDEO_HW_BITBLT - graphic driver supports hardware bit blt
|
|
*
|
|
* Console Parameters are set by graphic drivers global struct:
|
|
*
|
|
* VIDEO_VISIBLE_COLS - x resolution
|
|
* VIDEO_VISIBLE_ROWS - y resolution
|
|
* VIDEO_PIXEL_SIZE - storage size in byte per pixel
|
|
* VIDEO_DATA_FORMAT - graphical data format GDF
|
|
* VIDEO_FB_ADRS - start of video memory
|
|
*
|
|
* VIDEO_KBD_INIT_FCT - init function for keyboard
|
|
* VIDEO_TSTC_FCT - keyboard_tstc function
|
|
* VIDEO_GETC_FCT - keyboard_getc function
|
|
*
|
|
* CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner.
|
|
* Use CONFIG_SPLASH_SCREEN_ALIGN with
|
|
* environment variable "splashpos" to place
|
|
* the logo on other position. In this case
|
|
* no CONSOLE_EXTRA_INFO is possible.
|
|
* CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo
|
|
* CONFIG_CONSOLE_EXTRA_INFO - display additional board information
|
|
* strings that normaly goes to serial
|
|
* port. This define requires a board
|
|
* specific function:
|
|
* video_drawstring (VIDEO_INFO_X,
|
|
* VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
|
|
* info);
|
|
* that fills a info buffer at i=row.
|
|
* s.a: board/eltec/bab7xx.
|
|
*
|
|
* CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last
|
|
* character. No blinking is provided.
|
|
* Uses the macros CURSOR_SET and
|
|
* CURSOR_OFF.
