And make it black is usually done in software (by memsetting the screen with
the black color).
So why not this: In fbcon_blank(), if the blank parameter is:
0 - unblank the screen, and call info->fbops->fb_blank(VESA_NO_BLANKING),
then return a nonzero value to force a redraw.
1,2,3,4 - clear the screen with all black
2,3,4 - call info->fbops->fb_blank(blank - 1);
Similarly, we can do the same thing in fbmem.c:fb_blank(), but without the software
blanking.
Drivers will just need to follow the VESA_* defines in fb.h (which happens to be also
defined in console.h)Ah... so radeonfb is correct then, and fb_blank() is not ? X is definitely passing +1 values it seems.
