When writing drivers, you cannot in general use routines which are

<title>Frame Buffer Library</title>
|
|
|
|
<para>
|
|
The frame buffer drivers depend heavily on four data structures.
|
|
These structures are declared in include/linux/fb.h. They are
|
|
fb_info, fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs.
|
|
The last three can be made available to and from userland.
|
|
</para>
|
|
|
|
<para>
|
|
fb_info defines the current state of a particular video card.
|
|
Inside fb_info, there exists a fb_ops structure which is a
|
|
collection of needed functions to make fbdev and fbcon work.
|
|
fb_info is only visible to the kernel.
|
|
</para>
|
|
|
|
<para>
|
|
fb_var_screeninfo is used to describe the features of a video card
|
|
that are user defined. With fb_var_screeninfo, things such as
|
|
depth and the resolution may be defined.
|
|
</para>
|
|
|
|
<para>
|
|
The next structure is fb_fix_screeninfo. This defines the
|
|
properties of a card that are created when a mode is set and can't
|
|
be changed otherwise. A good example of this is the start of the
|
|
frame buffer memory. This "locks" the address of the frame buffer
|
|
memory, so that it cannot be changed or moved.
|
|
</para>
|
|
|
|
<para>
|
|
The last structure is fb_monospecs. In the old API, there was
|
|
little importance for fb_monospecs. This allowed for forbidden things
|
|
such as setting a mode of 800x600 on a fix frequency monitor. With
|
|
the new API, fb_monospecs prevents such things, and if used
|
|
correctly, can prevent a monitor from being cooked. fb_monospecs
|
|
will not be useful until kernels 2.5.x.
