new cursor

[James S. <jsi...@li...>]

I seen a email about hardware cursor support and I have been giving it
alot of thought. It is heavly based on solaris solution and it works
very nice with X windows. The nice thing about this is the state of
the hardware can be changed in one function call. Unlike some of the
problem we see from fb_fix and fb_var being seperate. Here is what I
purpose:

struct fbcurpos {
	__u16 x;
	__u16 y;
};

#define FB_CUR_SETCUR   0x01
#define FB_CUR_SETPOS   0x02
#define FB_CUR_SETHOT   0x04
#define FB_CUR_SETCMAP  0x08
#define FB_CUR_SETSHAPE 0x10
#define FB_CUR_SETALL   0x1F

struct fbcursor {
	__u16 set;  /* For above values. We tell fbdev what data to use. */
	__u16 enable;            /* Turn cursor on/off */
	struct fbcurpos pos;     /* Where the cursor is */
	struct fbcurpos hotspot; /* The cursors hotspot */
	struct fbcmap cmap;	 /* For those colorful cursors */
	struct fbcurpos size;	 /* Its width and height */
	char *image;		 /* Its bitmap */
	char *mask;		 /* Its mask for XORing */
};

So what do you think?

renders the sufferer barely able to perform the simplest task. 2. A disease.
