     fb_info, fb_map - direct framebuffer access

 <strong>SYNOPSIS</strong>

 <strong>DESCRIPTION</strong>
     These syscalls allow userspace programs to access the linear
     framebuffer directly for graphical output.

    <strong>fb_map</strong>
-    Maps the physical framebuffer into the process address space at

     Each pixel is a 32-bit value in 0xAARRGGBB format (blue in the
     low byte). Writing to this memory directly updates the screen.
