What has to be done is this. Most current fbdev drivers have a
fb_info_xxx {
struct fb_info info
....
hardware dependent stuff
...
[often this]
fb_var_screeninfo var
fb_fix_screeninfo fix
}
What the new system is
fb_info {
var; /* I place var, fix and cmap into fb_info. */
fix;
cmap;
par; /* Hardware dependent */
}
Damn I don't have the vfb.c.diff to show how to do it. Go to
http://www.linux-fbdev.org and go to the section that has the mailing list
archive. You will see my most recent patch against vfb.c. This is
basically what the new drivers will look like. Once this is in more
changes will occur but these changes are the first step. Look at fb.h
also. Read my howto at http://www.linux-fbdev.org. It gives you more
ideas. To see the final idea of what my patch will look like go to
http://imperial.edgeglobal.com/~jsimmons and grab the linux-2.3.25-fb
patch. Take a look at it, especially vfb.c.
P.S
Sorry but I have to go. I will be gone for the weekend in San Jose. In
fact I'm leaving right now. I will be back monday. Jon you have my hotel
phone number right? My interview is at 1:00 PM. I should be done by 5 or
6. See you later.
