27 | * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel. | |
28 | * | |
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. | |
33 | * | |
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. | |
39 | ||
40 | The driver uses graphic specific defines/parameters/functions: | |
41 | ||
42 | (for SMI LynxE graphic chip) | |
43 | ||
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 | |
48 | ||
49 | Console Parameters are set by graphic drivers global struct: | |
50 | ||
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 | |
56 | ||
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 | |
61 | ||
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 | |
a6c7ad2f | 68 | CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo |
c609719b WD |
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, | |
74 | info); | |
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). | |
82 | ||
83 | CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last character. No | |
84 | blinking is provided. Uses the macros CURSOR_SET | |
85 | and CURSOR_OFF. | |
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 | |
