[04/05] intelfb: implement FBIO_WAITFORVSYNC ioctl
The (unofficial) FBIO_WAITFORVSYNC ioctl is implemented by sleeping on the appropriate waitqueue, as defined in my earlier patch. Currently, only display 0 (aka pipe A) is supported.

[03/05] intelfb: Implement basic interrupt handling
Functions have been added to enable and disable interrupts using the MMIO registers. Currently only pipe A vsync interrupts are enabled.
A generalized vsync accounting struct is defined, with the intent that it can encapsulate per-pipe vsync related info in the future. Currently a single instance is hard-coded.
The interrupt service routine currently only looks for vsync interrupts on pipe A, and increments a counter and wakes up anyone waiting on it.
This implementation is heavily influenced by similar implementations in the atyfb and matroxfb drivers.

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.

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.

The EDID block should specify the display's operating limits (vertical and
horizontal sync ranges, and maximum dot clock). If not given by the EDID
block, the ranges are extrapolated from the modelist. However, the
computation used is only a rough approximation, and the resulting values may
not reflect the actual capability of the display. This problem is frequently
encountered when the EDID block has a single entry, the single mode entry will
fail validation.
To prevent this, calculate the values based on the same method used in

Reported by: Rich (Bugzilla Bug 6417)
"if savage driver is used in x.org together with savagefb, it results in
seriously garbled and distorted screen - coupled with severe slowdowns."
This bug is the result of Xorg unable to handle savagefb altering the
hardware which results in X failing to start properly and/or failed console
switching.
Add savagefb_state_save and savagefb_state_restore. These hooks will only
save and restore the extended VGA registers. Standard VGA registers will be
left alone. This is enough to make savagefb play nicely with the latest
Xorg savage driver, and perhaps with savage DRI. (Transient screen artifacts
may appear before X loads and during console switches).
(Unfortunately, blanking the screen also leaves Xorg in a blanked state, so I
have to unblank the screen before Xorg loads. So I doubt if the transient
screen artifacts will be completely invisible but hopefully it will only be
for a shorter duration (not much).)

Priority: not critical.
Change 3 functions from __init to __devinit.
Could be an init/probe problem in theory, but not observed, so not
high priority IMO.

This patch contains a total rewrite of the backlight infrastructure for
portable Apple computers. Backward compatibility is retained. A sysfs
interface allows userland to control the brightness with more steps than
before. Userland is allowed to upload a brightness curve for different

Remove VM_LOCKED before remap_pfn range from device drivers and get rid of
VM_SHM.
remap_pfn_range() already sets VM_IO. There is no need to set VM_SHM since
it does nothing. VM_LOCKED is of no use since the remap_pfn_range does not
place pages on the LRU. The pages are therefore never subject to swap
anyways. Remove all the vm_flags settings before calling remap_pfn_range.
After removing all the vm_flag settings no use of VM_SHM is left. Drop it.

VGA_MAP_MEM translates to ioremap() on some architectures. It makes sense
to do this to vga_vram_base, because we're going to access memory between
vga_vram_base and vga_vram_end.
But it doesn't really make sense to map starting at vga_vram_end, because
we aren't going to access memory starting there. On ia64, which always has
to be different, ioremapping vga_vram_end gives you something completely
incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being
nonsense.
As a bonus, we often know the size up front, so we can use ioremap()
correctly, rather than giving it a zero size.

There has been a longstanding problem with the Matrox G450 and perhaps
other similar cards, with modes "above" 1280x1024-60 on ppc/ppc64 boxes
running Linux. Higher resolutions and/or higher refresh rates resulted in
a very noticably "jittery" display, and sometimes no display, depending on
the physical monitor. This patch fixes that problem on the systems I have
easy access to...
I've tested with SLES9SP3 (2.6.5+ kernel) and 2.6.16-rc6 custom kernels on
an IBM eServer p5 520 w/G450 (a.k.a GXT135P on IBM's ppc64 systems), and a
colleague of mine (Ian Romanick) tested it successfully on an Apple ppc32
box (w/GXT135P). I also tested it on IA32 box I have with a GXT135P to
verify that it didn't obviously break anything. In my testing, I covered
single-card, single and dual-head setups using both HD15 and DVI-D signals,
on both the IA32 and ppc64 boxes. While everything appeared fine on both
boxes, I did encounter one problem: I can't get any signal on the DVI-D
output on the ppc64 box. However, this is also the case without my patch.
I just noticed that screen-blanking only occurs on the primary display as
well.

The driver has 2 methods for setting the color map, using the protected

registers. The former is not supported in x86_64 and the latter is enabled
only in i386.
Fix by enabling the latter method in x86_64 only if supported by the BIOS.

The monochrome->color expansion routine that handles bitmaps which have

This is caused by a bogus bit test in slow_imageblit().
Fix.
This patch may deserve to go to the stable tree. The code has already been
well tested in little-endian machines. It's only in big-endian where there is
uncertainty and Herbert confirmed that this is the correct way to go.

Updates to the HP Jornada 680 Backlight driver:
- Correct the suspend/resume functions so the driver compiles
(SUSPEND_POWER_DOWN/RESUME_POWER_ON no longer exist).
- Convert the driver to match the recent platform device changes.
- Replace the unsafe static struct platform_device with dynamic allocation.
- Convert the driver to the new backlight code.
This has not been tested on a device due to lack of hardware but wouldn't
compile beforehand.

Backlight class attributes are currently easy to implement incorrectly.
Moving certain handling into the backlight core prevents this whilst at the
same time makes the drivers simpler and consistent. The following changes are
included:
The brightness attribute only sets and reads the brightness variable in the
backlight_properties structure.
The power attribute only sets and reads the power variable in the
backlight_properties structure.
Any framebuffer blanking events change a variable fb_blank in the
backlight_properties structure.
The backlight driver has only two functions to implement. One function is
called when any of the above properties change (to update the backlight
brightness), the second is called to return the current backlight brightness
value. A new attribute "actual_brightness" is added to return this brightness
as determined by the driver having combined all the above factors (and any
driver/device specific factors).
Additionally, the backlight core takes care of checking the maximum brightness
is not exceeded and of turning off the backlight before device removal.
The corgi backlight driver is updated to reflect these changes.

The current display was not saved during initialization. This leads to hard
to track console corruption, such as a misplaced cursor, which is correctible
by switching consoles. Fix this minor bug.

The boot cmdline is parsed in parse_early_param() and
parse_args(,unknown_bootoption).
And __setup() is used in obsolete_checksetup().
start_kernel()
-> parse_args()
-> unknown_bootoption()
-> obsolete_checksetup()
If __setup()'s callback (->setup_func()) returns 1 in
obsolete_checksetup(), obsolete_checksetup() thinks a parameter was
handled.
If ->setup_func() returns 0, obsolete_checksetup() tries other
->setup_func(). If all ->setup_func() that matched a parameter returns 0,
a parameter is seted to argv_init[].
Then, when runing /sbin/init or init=app, argv_init[] is passed to the app.
If the app doesn't ignore those arguments, it will warning and exit.
This patch fixes a wrong usage of it, however fixes obvious one only.

This removes statically assigned platform numbers and reworks the
powerpc platform probe code to use a better mechanism. With this,
board support files can simply declare a new machine type with a
macro, and implement a probe() function that uses the flattened
device-tree to detect if they apply for a given machine.
We now have a machine_is() macro that replaces the comparisons of
_machine with the various PLATFORM_* constants. This commit also
changes various drivers to use the new macro instead of looking at
_machine.
