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_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 */ #include #ifdef CONFIG_CFB_CONSOLE #include /*****************************************************************************/ /* Console device defines with SMI graphic */ /* Any other graphic must change this section */ /*****************************************************************************/ #ifdef CONFIG_VIDEO_SMI_LYNXEM #define VIDEO_FB_LITTLE_ENDIAN #define VIDEO_HW_RECTFILL #define VIDEO_HW_BITBLT #endif /*****************************************************************************/ /* Defines for the CT69000 driver */ /*****************************************************************************/ #ifdef CONFIG_VIDEO_CT69000 #define VIDEO_FB_LITTLE_ENDIAN #define VIDEO_HW_RECTFILL #define VIDEO_HW_BITBLT #endif /*****************************************************************************/ /* Defines for the SED13806 driver */ /*****************************************************************************/ #ifdef CONFIG_VIDEO_SED13806 #define VIDEO_FB_LITTLE_ENDIAN #define VIDEO_HW_RECTFILL #define VIDEO_HW_BITBLT #endif /*****************************************************************************/ /* Include video_fb.h after definitions of VIDEO_HW_RECTFILL etc */ /*****************************************************************************/ #include /*****************************************************************************/ /* some Macros */ /*****************************************************************************/ #define VIDEO_VISIBLE_COLS (pGD->winSizeX) #define VIDEO_VISIBLE_ROWS (pGD->winSizeY) #define VIDEO_PIXEL_SIZE (pGD->gdfBytesPP) #define VIDEO_DATA_FORMAT (pGD->gdfIndex) #define VIDEO_FB_ADRS (pGD->frameAdrs) /*****************************************************************************/ /* Console device defines with i8042 keyboard controller */ /* Any other keyboard controller must change this section */ /*****************************************************************************/ #ifdef CONFIG_I8042_KBD #include #define VIDEO_KBD_INIT_FCT i8042_kbd_init() #define VIDEO_TSTC_FCT i8042_tstc #define VIDEO_GETC_FCT i8042_getc #endif /*****************************************************************************/ /* Console device */ /*****************************************************************************/ #include #include #include #include #ifdef CFG_CMD_DATE #include #endif /*****************************************************************************/ /* Cursor definition: */ /* CONFIG_CONSOLE_CURSOR: Uses a timer function (see drivers/i8042.c) to */ /* let the cursor blink.
