| * |
| * 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) |
| CFG_CONSOLE_BLINK_COUNT - value for delay loop - blink rate |
| CONFIG_CONSOLE_TIME - display time/date in upper right corner, |
| needs CFG_CMD_DATE and CONFIG_CONSOLE_CURSOR |
| CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner |
| 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 |
