A sample// 	driver has been developed for the pc386 BSP. See// 	pc386/fb_vga.c as a sample.// 	* Added Uniform Input Device interface for MicroWindows.// 	See PC386 bsp for sample drivers for mouse and keyboard (console).// 	* mw-bf: New directory.// 	* Makefile.am, configure.in, wrapup/Makefile.am: Account for mw-fb.// 	* mw-fb/Makefile.am: New file.// 	* mw-fb/mw_fb.c: New file.// 	* mw-fb/mw_fb.h: New file.// 	* mw-fb/mw_uid.c: New file.// 	* mw-fb/mw_uid.h: New file./////////////////////////////////////////////////////////////////////////////////*/#ifndef _MW_FB_H#define _MW_FB_H#ifdef	__cplusplusextern "C" {#endif/* ioctls   0x46 is 'F'                                */#define FB_SCREENINFO             0x4601#define FB_GETPALETTE             0x4602#define FB_SETPALETTE             0x4603#define FB_EXEC_FUNCTION          0x4604#define FB_TYPE_PACKED_PIXELS          0    /* Packed Pixels    */#define FB_TYPE_PLANES                 1    /* Non interleaved planes */#define FB_TYPE_INTERLEAVED_PLANES     2    /* Interleaved planes    */#define FB_TYPE_TEXT                   3    /* Text/attributes    */#define FB_TYPE_VGA_PLANES             4    /* EGA/VGA planes    */#define FB_TYPE_VIRTUAL_BUFFER         5    /* Virtual Buffer */#define FB_VISUAL_MONO01               0    /* Monochr. 1=Black 0=White */#define FB_VISUAL_MONO10               1    /* Monochr. 1=White 0=Black */#define FB_VISUAL_TRUECOLOR            2    /* True color    */#define FB_VISUAL_PSEUDOCOLOR          3    /* Pseudo color (like atari) */#define FB_VISUAL_DIRECTCOLOR          4    /* Direct color */#define FB_VISUAL_STATIC_PSEUDOCOLOR   5    /* Pseudo color readonly */#define FB_ACCEL_NONE                  0    /* no hardware accelerator    *//* no dependency on any other header file */typedef  unsigned long  __u32;typedef  unsigned short __u16;struct fb_screeninfo {    __u32 xres;                  /* visible resolution        */    __u32 yres;    __u32 bits_per_pixel;        /* guess what            */	 __u32 line_length;          /* number of chars per line */     volatile char *smem_start; /* Start of frame buffer mem  */                                /* (physical address)         */    __u32 smem_len;             /* Length of frame buffer mem */    __u32 type;                 /* see FB_TYPE_*              */    __u32 visual;               /* see FB_VISUAL_*            */};struct fb_cmap {    __u32 start;                /* First entry    */    __u32 len;                  /* Number of entries */    __u16 *red;                 /* Red values    */    __u16 *green;    __u16 *blue;    __u16 *transp;              /* transparency, can be NULL */};/* type of function to be executed at the driver level */#define FB_FUNC_ENTER_GRAPHICS   0#define FB_FUNC_EXIT_GRAPHICS    1#define FB_FUNC_IS_DIRTY         2#define FB_FUNC_GET_MODE         3struct fb_exec_function{    int    func_no;    void  *param;};/* Micro Framebuffer API Wrapper *//* * This function returns the information regarding the display. * It is called just after the driver be opened to get all needed * information about the driver.
