The control for binding/unbinding is moved from fbcon to the console layer.
Thus the fbcon sysfs attributes, attach and detach, are also gone.
1. Add a notifier event that tells fbcon if a framebuffer driver has been
unregistered. If no registered driver remains, fbcon will unregister
itself from the console layer.
2. Replaced calls to give_up_console() with unregister_con_driver().
3. Still use take_over_console() instead of register_con_driver() to
maintain compatibility
4. Respect the parameter first_fb_vc and last_fb_vc instead of using 0 and
MAX_NR_CONSOLES - 1. These parameters are settable by the user.
5. When fbcon is completely unbound from the console layer, fbcon will
also release (iow, decrement module reference counts to zero) all fbdev
drivers. In other words, a bind or unbind request from the console layer
will propagate down to the framebuffer drivers.
6. If fbcon is not bound to the console, it will ignore all notifier
events (except driver registration and unregistration) and all sysfs
requests.

Add the ability to detach and attach the framebuffer console to and from the
vt layer. This is done by echo'ing any value to sysfs attributes located in
class/graphics/fbcon. The two attributes are:
attach - bind fbcon to the vt layer
detach - unbind fbcon from the vt layer
Once fbcon is detached from the vt layer, fbcon can be unloaded if compiled as
a module. This feature is quite useful for developers who work on the
framebuffer or console subsystem. This is also useful for users who want to
go to text mode or graphics mode without having to reboot.
Directly unloading the fbcon module is not possible because the vt layer
increments the module reference count for all bound consoles. Detaching fbcon
decrements the module reference count to zero so unloading becomes possible.
Detaching fbcon may interfere with X and/or DRM.

In order for this feature to work, an interface will be needed. The most
appropriate is sysfs. However, the framebuffer console has no sysfs entry
yet. This will create a sysfs class device entry for fbcon under
/sys/class/graphics.
Add a class_device entry 'fbcon' under class 'graphics'. Console-specific
attributes which where previously under class/graphics/fb[x] are moved to
class/graphics/fbcon. These attributes, 'con_rotate' and 'con_rotate_all',
are also renamed to 'rotate' and 'rotate_all' respectively.

Detaching fbcon allows individual drivers to be unloaded. However several
drivers call pci_disable_device() upon exit. This function will disable the
BAR's which will kill VGA text mode and/or affect X/DRM.
To prevent this, remove calls to pci_disable_device() from several drivers.

One of the limitations of the framebuffer console system is its inablity to
unload or detach itself from the console layer. And once it loads, it also
locks in framebuffer drivers preventing their unload. Although the con2fbmap
utility does provide a means to unload individual drivers, it requires that at
least one framebuffer driver is loaded for use by fbcon.
With this change, it is possible to detach fbcon from the console layer. If it
is detached, it will reattach the boot console driver (which is permanently
loaded) back to the console layer so the system can continue to work. As a
consequence, fbcon will also decrement its reference count of individual
framebuffer drivers, allowing all of these drivers to be unloaded even if
fbcon is still loaded.
Unless you use drivers that restores the display to text mode (rivafb and
i810fb, for example), detaching fbcon does require assistance from userspace
tools (ie, vbetools) for text mode to be restored completely. Without the
help of these tools, fbcon will leave the VGA console corrupted. The methods
that can be used will be described in Documentation/fb/fbcon.txt.
Because the vt layer also increments the module reference count for each
console driver, fbcon cannot be directly unloaded. It must be detached first
prior to unload.
Similarly, fbcon can be reattached to the console layer without having to
reload the module. A nice feature if fbcon is compiled statically.
Attaching and detaching fbcon is done via sysfs attributes. A class device
entry for fbcon is created in /sys/class/graphics. The two attributes that
controls this feature are detach and attach. Two other attributes that are
piggybacked under /sys/class/graphics/fb[n] that are fbcon-specific,
'con_rotate' and 'con_rotate_all' are moved to fbcon. They are renamed as
'rotate' and 'rotate_all' respectively.
Overall, this feature is a great help for developers working in the
framebuffer or console layer. There is not need to continually reboot the
kernel for every small change. It is also useful for regular users who wants
to choose between a graphical console or a text console without having to
reboot.
Example usage for x86:
/* start in text mode */
modprobe xxxfb
modprobe fbcon
/* graphical mode with fbcon using xxxfb */
echo 1 > /sys/class/graphics/fbcon/detach
/* back to text mode, will produce corrupt display unless vbetool is used */
rmmod xxxfb
modprobe yyyfb
/* back to graphical mode with fbcon using yyyfb */
Before trying out this feature, please read Documentation/fb/fbcon.txt.
This patch:
In order for fbcon to detach itself from the console layer, vgacon, which is a
boot console driver, must be fixed so it can retake the console multiple
times, not just during init. The following needs to be done:
- remove __init from the vgacon_startup, this is called again by
take_over_console().
- vc->rows and vc->cols are set manually by vgacon during init. After init,
vc_resize() can be used
- make sure the scrollback_buffer is not reallocated

This is a fix for the most annoying problem that remained with neofb:
After "setterm -powersave powerdown" the console blanker will disable the
backlight after the given timeout expires. If this happens after the lid
has been shut, we read "LCD off" from the register and store that in the
driver. Once the lid is opened, the backlight turns on, but any key press
that would awaken the blanked console will switch the backlight off again.
The workaround so far was to use the "display config toggle" Fn key combo -
once if no external display is attached, otherwise as often as required to
restore the desired display setup.
The following patch fixes the issue at least for the LCD-only case, with no
external monitor attached. Other display setup permutations are pending
further testing, but so far I can guarantee at least no negative change in
behaviour, if any at all.
