27 * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
29 * At the moment only the 8x16 font is tested and the font fore- and
30 * background color is limited to black/white/gray colors. The Linux
31 * logo can be placed in the upper left corner and additional board
32 * information strings (that normaly goes to serial port) can be drawed.
34 * The console driver can use the standard PC keyboard interface (i8042)
35 * for character input. Character output goes to a memory mapped video
36 * framebuffer with little or big-endian organisation.
37 * With environment setting 'console=serial' the console i/o can be
38 * forced to serial port.
40 The driver uses graphic specific defines/parameters/functions:
42 (for SMI LynxE graphic chip)
44 CONFIG_VIDEO_SMI_LYNXEM - use graphic driver for SMI 710,712,810
45 VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian
46 VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill
47 VIDEO_HW_BITBLT - graphic driver supports hardware bit blt
49 Console Parameters are set by graphic drivers global struct:
51 VIDEO_VISIBLE_COLS - x resolution
52 VIDEO_VISIBLE_ROWS - y resolution
53 VIDEO_PIXEL_SIZE - storage size in byte per pixel
54 VIDEO_DATA_FORMAT - graphical data format GDF
55 VIDEO_FB_ADRS - start of video memory
57 CONFIG_I8042_KBD - AT Keyboard driver for i8042
58 VIDEO_KBD_INIT_FCT - init function for keyboard
59 VIDEO_TSTC_FCT - keyboard_tstc function
60 VIDEO_GETC_FCT - keyboard_getc function
62 CONFIG_CONSOLE_CURSOR - on/off drawing cursor is done with delay
63 loop in VIDEO_TSTC_FCT (i8042)
64 CFG_CONSOLE_BLINK_COUNT - value for delay loop - blink rate
65 CONFIG_CONSOLE_TIME - display time/date in upper right corner,
66 needs CFG_CMD_DATE and CONFIG_CONSOLE_CURSOR
67 CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner
68 CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo
69 CONFIG_CONSOLE_EXTRA_INFO - display additional board information strings
70 that normaly goes to serial port. This define
71 requires a board specific function:
72 video_drawstring (VIDEO_INFO_X,
73 VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
75 that fills a info buffer at i=row.
76 s.a: board/eltec/bab7xx.
77 CONFIG_VGA_AS_SINGLE_DEVICE - If set the framebuffer device will be initialised
78 as an output only device. The Keyboard driver
79 will not be set-up. This may be used, if you
80 have none or more than one Keyboard devices
81 (USB Keyboard, AT Keyboard).
83 CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last character. No
84 blinking is provided. Uses the macros CURSOR_SET
86 CONFIG_VIDEO_HW_CURSOR: - Uses the hardware cursor capability of the
87 graphic chip. Uses the macro CURSOR_SET.
88 ATTENTION: If booting an OS, the display driver
89 must disable the hardware register of the graphic
90 chip. Otherwise a blinking field is displayed
