|
|
* 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 normaly goes to serial port) can be drawed.
|
|
*
|
|
* The console driver can use the standard PC keyboard interface (i8042)
|
|
* for character input. 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)
|
|
|
|
CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810
|
|
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
|
|
|
|
CONFIG_I8042_KBD - AT Keyboard driver for i8042
|
|
VIDEO_KBD_INIT_FCT - init function for keyboard
|
|
VIDEO_TSTC_FCT - keyboard_tstc function
|
|
VIDEO_GETC_FCT - keyboard_getc function
|
|
|
|
CONFIG_CONSOLE_CURSOR - on/off drawing cursor is done with delay
|
|
loop in VIDEO_TSTC_FCT (i8042)
|
|
CONFIG_SYS_CONSOLE_BLINK_COUNT - value for delay loop - blink rate
|
|
CONFIG_CONSOLE_TIME - display time/date in upper right corner,
|
|
needs CONFIG_CMD_DATE and CONFIG_CONSOLE_CURSOR
|
|
CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner
|
|
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_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be initialised
|
|
as an output only device. The Keyboard driver
|
|
will not be set-up. This may be used, if you
|
|
have none or more than one Keyboard devices
|
|
(USB Keyboard, AT Keyboard).
|
|
|
|
CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last character. No
|
|
blinking is provided. Uses the macros CURSOR_SET
|
|
and CURSOR_OFF.
|
|
CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability of the
|
|
graphic chip. Uses the macro CURSOR_SET.
|
|
ATTENTION: If booting an OS, the display driver
|
|
must disable the hardware register of the graphic
|
|
chip. Otherwise a blinking field is displayed
