This change lets the code match the description.
Support for vfb:disable is kept for backwards compatibility; vfb:off works
because it is tested at a higher level.
Note: any undefined option (e.g. vfb:enable) will also enable this driver.
The relevant code has been unchanged since before the migration to

This is the SuperH Mobile LCDC frame buffer driver V2, adding support for
the LCDC block found in SuperH Mobile processors. The hardware supports
up to two LCD panels per LCDC block, and both RGB and SYS interfaces can
be used to hook up LCD panels/modules.
The device driver is a regular platform driver, so LCD configuration and
board specific hooks are passed to the driver using platform data. LCD
modules using SYS interface often require special configuration using the
SYS bus, and to solve this cleanly the driver provides SYS interface
operations to the board code.
Tested on sh7723 and sh7722 processors with a SYS16A QVGA panel and WVGA
panels using RGB16 and RGB18 interfaces.

mdacon incorrectly detects MDA hardware on systems without such graphics card.
One may load this module by chance, for example when doing some systematical
module-testing, and if there is no Monochrome Display Adapter attached ,
module init renders vc1-16 completely unusable.
I and others have run into this more than once. see [Bug 224522 - modprobe
mdacon freezes machine -> https://bugzilla.novell.com/show_bug.cgi?id=224522 ]
for example
Apparently proper MDA detection seems to be broken for a long time - seems to
be related to those #ifdef TEST_MDA_B statements added by Edward Betts.
this commit back in 2002 made things even worse :
http://git.kernel.org/?p=linux/kernel/git/tglx/history.git;a=commit;h=c72757b49c88914433244757fb4967fc63546685
It changed default vc allocation from 13-16 to 1-16 for no apparent reason
(!?) , and with that (and without X), mdacon grabs the vc you`re currently
sitting on and locks you out.
this is from Kconfig :
>config MDA_CONSOLE
> depends on !M68K && !PARISC && ISA
> tristate "MDA text console (dual-headed) (EXPERIMENTAL)"
> ---help---
> Say Y here if you have an old MDA or monochrome Hercules graphics
> adapter in your system acting as a second head ( = video card). You
> will then be able to use two monitors with your Linux system. Do not
> say Y here if your MDA card is the primary card in your system; the
> normal VGA driver will handle it.
As we can see mdacon is just meant as an additional driver for dual-head
setup, and since kernel 2.4.36 still defaults to vc13-16 , setting the default
back to that value again shouldn`t do any harm.
Hereby i'm reverting that change, setting default back to to vc13-16 again.
Besides the fact that mdacon may be rarely or never be used these days and
could perhaps put to trash anyway (pre-dinosaur hardware!), indeed this is not
a real solution, but at least it removes the unfortunate side-effect of
messing up the vc you`re working on.

- blacklist the Image975 chipset from setting PCI burst

Improved values for some registers after Xorg Trident driver. The main
problem was that values set by BIOS have been ignored.
This patch completely remove random pixels ("snow") on the TGUI 9680 and
9440 (not supported yet by the driver). It does not help with the "snow"
on 3DImage and Blade3D cards.
There is also small improvement in timing calculations (hblank start and

On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit
boundary. For example:
u64 val = PAGE_ALIGN(size);
always returns a value < 4GB even if size is greater than 4GB.
The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for
example):
#define PAGE_SHIFT 12
#define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT)
#define PAGE_MASK (~(PAGE_SIZE-1))
...
#define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK)
The "~" is performed on a 32-bit value, so everything in "and" with
PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary.
Using the ALIGN() macro seems to be the right way, because it uses
typeof(addr) for the mask.
Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in
include/linux/mm.h.

This patch is a bugfix for how defio handles multiple processes manipulating
the same framebuffer.
Thanks to Bernard Blackham for identifying this bug.
It occurs when two applications mmap the same framebuffer and concurrently
write to the same page. Normally, this doesn't occur since only a single
process mmaps the framebuffer. The symptom of the bug is that the mapping
applications will hang. The cause is that defio incorrectly tries to add the
same page twice to the pagelist. The solution I have is to walk the pagelist
and check for a duplicate before adding. Since I needed to walk the pagelist,
I now also keep the pagelist in sorted order.

The pvfb backend indicates dynamic mode support by creating node
feature_resize with a non-zero value in its xenstore directory.
xen-fbfront sends a resize notification event on mode change. Fully
backwards compatible both ways.
Framebuffer size and initial resolution can be controlled through
kernel parameter xen_fbfront.video. The backend enforces a separate
size limit, which it advertises in node videoram in its xenstore
directory.
xen-kbdfront gets the maximum screen resolution from nodes width and
height in the backend's xenstore directory instead of hardcoding it.
Additional goodie: support for larger framebuffers (512M on a 64-bit
system with 4K pages).
Changing the number of bits per pixels dynamically is not supported,
yet.

Without console= arguments on the kernel command line, the first
console to register becomes enabled and the preferred console (the one
behind /dev/console). This is normally tty (assuming
CONFIG_VT_CONSOLE is enabled, which it commonly is).
This is okay as long tty is a useful console. But unless we have the
PV framebuffer, and it is enabled for this domain, tty0 in domU is
merely a dummy. In that case, we want the preferred console to be the
Xen console hvc0, and we want it without having to fiddle with the
kernel command line. Commit b8c2d3dfbc
did that for us.
Since we now have the PV framebuffer, we want to enable and prefer tty
again, but only when PVFB is enabled. But even then we still want to
enable the Xen console as well.
Problem: when tty registers, we can't yet know whether the PVFB is
enabled. By the time we can know (xenstore is up), the console setup
game is over.
Solution: enable console tty by default, but keep hvc as the preferred
console. Change the preferred console to tty when PVFB probes
successfully, unless we've been given console kernel parameters.

commit 3888d4639e
lxfb: extend PLL table to support dotclocks below 25 MHz
Extends the PLL frequency table of the AMD Geode-LX frame buffer driver to
make use of the DIV4 bit, thus adding support for dotclocks between 6 and 25
MHz. These are needed for small LCDs (e.g. 320x240). Also inserts some
intermediate steps between pre-existing frequencies.
The problem was the insertion of intermediate steps into the frequency
table; they would cause the wrong frequency to be matched. This patch
drops those intermediate frequencies while keeping the sub-25MHz
frequencies.

The function framebuffer_release just calls kfree, so calling kfree
subsequently on the same argument represents a double free. The comments with
the definition of framebuffer_release in drivers/video/fbsysfs.c suggest that
a more elaborate definition of this function is planned, such that the
splitting up of framebuffer_release and kfree as done in the second instance
might someday make sense, but it does not make sense now.
This was found using the following semantic match.

Reasons:
1. straight forward: the name "LCD_COLOR_DSTN_16BPP" is much better
than "LCCR0_Pas | LCCR0_Color | LCCR0_Dual"
2. by defining LCD connection types as constants, it allows only
valid possibilities
3. by removing the dependency of register bits definitions, those
can be later moved into the body of pxafb.c, instead of having
a regs-lcd.h around
Currently, only lubbock, mainstone, zylonite and littleton have been
modified to support these types (see coming patches after this).
Other platforms are encouraged to change their way describing the

A command that causes a line feed while a background color is active,
such as
perl -e 'print "x" x 60, "\e[44m", "x" x 40, "\e[0m\n"'
and
perl -e 'print "x" x 40, "\e[44m\n", "x" x 40, "\e[0m\n"'
causes the line that was started as a result of the line feed to be completely
filled with the currently active background color instead of the default
color.
When scrolling, part of the current screen is memcpy'd/memmove'd to the new
region, and the new line(s) that will appear as a result are cleared using
memset. However, the lines are cleared with vc->vc_video_erase_char, causing
them to be colored with the currently active background color. This is
different from X11 terminal emulators which always paint the new lines with
the default background color (e.g. `xterm -bg black`).
The clear operation (\e[1J and \e[2J) also use vc_video_erase_char, so a new
vc->vc_scrl_erase_char is introduced with contains the erase character used
for scrolling, which is built from vc->vc_def_color instead of vc->vc_color.

The following features are supported:
plane 0 works as a regular frame buffer, can be accessed by /dev/fb0
plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2
plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4
Special ioctls support AOIs
All /dev/fb* can be used as regular frame buffer devices, except hardware
change can only be made through /dev/fb0. Changing pixel clock has no effect
on other fbs.
Limitation of usage of AOIs:
AOIs on the same plane can not be horizonally overlapped
AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1
AOIs can not beyond phisical display area. Application should check AOI geometry
before changing physical resolution on /dev/fb0
required command line parameters to preallocate memory for frame buffer diufb.
optional command line parameters to set modes and monitor
video=fslfb:[resolution][,bpp][,monitor]
Syntax:
Resolution
xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional
eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60
Bpp
bpp=32, bpp=24, or bpp=16
Monitor
monitor=0, monitor=1, monitor=2
0 is DVI
1 is Single link LVDS
2 is Double link LVDS
Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three
monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching
monirot port for MPC5121ADS has no effect.
If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.

Since there's no way to autodetect panel modes, we're forced to hardcode them
in the driver and add a big fat #ifdef. The OLPC DCON needs a specific mode
line (at 1200x900). This adds it to both gxfb and lxfb.
(Jordan said: We could probably detect the panel mode, but there isn't any
reason to since the panel timings are well known and won't change. While OFW
detection would be good computer science fu, it would be a wasted effort since
its so easy to hard code them into the table.)

The legacy atmel LCDC IP uses a non standard color mode, "BGR-555.1" instead
"RGB-565". The major part of graphic stacks for embedded systems uses only
"RGB-565". It is possible to swap LCD IOs instead of doing this bit swapping
by software (See application note AT91SAM9 LCD Controller

If the user specified a fixed framebuffer address on the command line, it may
have been initialized already with a splash image or something, so we
shouldn't clear it.
Therefore, we should only initialize the framebuffer if we allocated it
ourselves. This patch also updates the AVR32 setup code to clear the
framebuffer if it allocated it itself, i.e. the user didn't provide a fixed
address or the reservation failed.
I've updated the at91 platform code as well so that it initializes the
framebuffer if it is located in SRAM, but I haven't tested that it actually
works.

Prior to suspend, we allocate and switch to a new VT; after suspend, we switch
back to the original VT. This can be slow, and is completely unnecessary if
the framebuffer we're using can restore video properly.
This adds a hook that allows drivers to select whether or not to do this vt
switch, and changes the gxfb driver to call this hook. It also adds a module
param to gxfb to allow controlling of the vt switch (defaulting to no switch).
(Note: I'm not convinced that console_sem is the best way to protect this, but
we should probably have some form of locking..)

- Create gxfb_par (based on geodefb_par), place it in gxfb.h

This does the following in preparation for register saving:
- moves the register definitions from video_gx.h and display_gx.h into
gxfb.h.
- renames GX_* registers to match their section (ie, VP_).
- renames register bitfields to match the data sheet (ie,
DC_DCFG_TGEN -> DC_DISPLAY_CFG_TGEN).
- for DC registers, rather than defining to specific addresses, use
an enum to number them sequentially and just multiply by 4(bytes) to
access them (in read_dc/write_dc).
- for VP and FP registers, use an enum and multiple by 8 (bytes). They're
64bit registers.

This creates read_dc/write_dc, read_vp/write_vp, and read_fp/write_fp for
reading and updating those registers. It creates gxfb.h to house these.
We also drop a no-op readl() from gx_set_mode. Other than that, there should
be no functionality change.

Use a command line option (vram) rather than hardcoding the vram size. LxFB
already does this; it's useful for machines that can't query the BIOS for fb
size. This patch originated from David Woodhouse, was modified by Jordan
Crouse, and was then modified further by me.
This also adds some gxfb documentation in Documentation/fb.

Drop the class/class_mask stuff; it's unnecessary as long as the vendor and

When the FP strap is enabled, don't turn on the CRT DACs - that will save
about 35 mA of power.

While running in flatpanel mode it is important to change the FP sync bits (VG
register 0x408) rather then the CRT sync bits (VG register 0x008). This patch
keeps the CRT sync bits at default when a flatpanel exists.
Note that this also fixes inverted logic; we want CRT_VSYNC_POL to be set (ie,
vsync is normally high) when FB_SYNC_VERT_HIGH_ACT is unset.

This cleans up a few MSR-using drivers in the following manner:
- Ensures MSRs are all defined in asm/geode.h, rather than in misc
places
- Makes the naming consistent; cs553[56] ones begin with MSR_,
GX-specific ones start with MSR_GX_, and LX-specific ones start
with MSR_LX_. Also, make the names match the data sheet.
- Use MSR names rather than numbers in source code
- Document the fact that the LX's MSR_PADSEL has the wrong value
in the data sheet. That's, uh, good to note.

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /

Add support for the framebuffers with non-native endianness. This is done via
FBINFO_FOREIGN_ENDIAN flag that will be used by the drivers. Depending on the
host endianness this flag will be overwritten by FBINFO_BE_MATH internal flag,
or cleared.
Tested to work on MPC8360E-RDK (BE) + Fujitsu MINT framebuffer (LE).
