f9101210e7 [PATCH] vfree and kfree cleanup in drivers/
This patch does a full cleanup of 'NULL checks before vfree', and a partial
cleanup of calls to kfree for all of drivers/ - the kfree bit is partial in
that I only did the files that also had vfree calls in them.  The patch
also gets rid of some redundant (void *) casts of pointers being passed to
[vk]free, and a some tiny whitespace corrections also crept in.

96fe6a2109 [PATCH] fbdev: Add VESA Coordinated Video Timings (CVT) support
The Coordinated Video Timings (CVT) is the latest standard approved by VESA
concerning video timings generation.  It addresses the limitation of GTF which
is designed mainly for CRT displays.  CRT's have a high blanking requirement
(as much as 25% of the horizontal frame length) which artificially increases
the pixelclock.  Digital displays, on the other hand, needs to conserve the
pixelclock as much as possible.  The GTF also does not take into account the
different aspect ratios in its calculation.

The new function added is fb_find_mode_cvt().  It is called by fb_find_mode()
if it recognizes a mode option string formatted for CVT.  The format is:

<xres>x<yres>[M][R][-<bpp>][<at-sign><refresh>][i][m]

The 'M' tells the function to calculate using CVT.  On it's own, it will
compute a timing for CRT displays at 60Hz.  If the 'R' is specified, 'reduced
blanking' computation will be used, best for flatpanels.  The 'i' and the 'm'
is for 'interlaced mode' and 'with margins' respectively.

To determine if CVT was used, check for dmesg for something like this:

CVT Mode - <pix>M<n>[-R], ie: .480M3-R  (800x600 reduced blanking)

where: pix - product of xres and yres, in MB
    M   - is a CVT mode
    n   - the aspect ratio (3 - 4:3; 4 - 5:4; 9 - 16:9, 15:9; A - 16:10)
    -R   - reduced blanking

5251bffc9b [PATCH] radeonfb: Only request resources we need
This patch changes radeon to request only resources 0 and 2 instead of all
3.  This works around problems with some setups where BAR 1 (IO BAR) has
not been assigned by the firmware since it's not used on the machine and
the kernel fails to assign something to it due to the card being between a
P2P bridge that was configured without an IO range at all.

This typically fixes radeonfb on some Apple Xserve G5 machines

c5eb5c1ea9 [PATCH] framebuffer: bit_putcs() optimization for 8x* fonts
This trivial patch gives a performance boost to the framebuffer console

Constructing the bitmaps that are given to the bitblit functions of the
framebuffer drivers is time consuming.  Here we avoide a call to the slow
fb_pad_aligned_buffer().  The patch replaces that call with a simple but
much more efficient bytewise copy.

The kernel spends a significant time at this place if you use 8x* fonts.
Every pixel displayed on your screen is prepared here.

Some benchmark results:

Displaying a file of 2000 lines with 160 characters each takes 889 ms
system time using cyblafb on my system (Im using a 1280x1024 video mode,
resulting in a 160x64 character console)

Displaying the same file with the enclosed patch applied to 2.6.13 only
takes 760 ms system time, saving 129 ms or 14.5%.

Font widths other than 8 are not affected.

The advantage and correctness of this patch should be obvious.

9fa68eae9f [PATCH] framebuffer: new driver for cyberblade/i1 graphics core
This is a framebuffer driver for the Cyberblade/i1 graphics core.

Currently tridenfb claims to support the cyberblade/i1 graphics core.  This
is of very limited truth.  Even vesafb is faster and provides more working
modes and a much better quality of the video signal.  There is a great
number of bugs in tridentfb ...  but most often it is impossible to decide
if these bugs are real bugs or if fixing them for the cyberblade/i1 core
would break support for one of the other supported chips.

Tridentfb seems to be unmaintained,and documentation for most of the
supported chips is not available.  So "fixing" cyberblade/i1 support inside
of tridentfb was not an option, it would have caused numerous
if(CYBERBLADEi1) else ...  cases and would have rendered the code to be
almost unmaintainable.

A first version of this driver was published on 2005-07-31.  A fix for a
bug reported by Jochen Hein was integrated as well as some changes
requested by Antonino A.  Daplas.

A message has been added to tridentfb to inform current users of tridentfb
to switch to cyblafb if the cyberblade/i1 graphics core is detected.

This patch is one logical change, but because of the included documentation
it is bigger than 70kb.  Therefore it is not sent to lkml and
linux-fbdev-devel,

- Fixed support for 320x240 STN panels (for embedded devices).

- Fixed many HDTV modes (525p, 750p, 1080i).

- Fixed PCI config register reading/writing to use proper kernel
  functions for this purpose.

- Fixed PCI ROM handling to use the kernel's proper functions.

- Removed lots of "typedef"s.

- Removed lots of code which was for X.org/XFree86 only.

- Fixed coding style in many places.

- Removed lots of 2.4 cruft.

- Reduced stack size by unifying two previously separate structs into
  one.

- Added new hooks for memory allocation (for DRM).  Now the driver can
  truly handle multiple cards, including memory management.

- Fixed numerous minor bugs.

5c06e2aa63 [PATCH] matroxfb: read MGA PInS data on PowerPC
This updates the matroxfb code so that it can find the PInS data embedded
in the BIOS on PowerPC cards.  The process for finding the data is
different on OpenFirmware cards than on x86 cards, and the code for doing
so was missing.

After patching, building, installing, and booting a kernel, you should grep
for "PInS" in /var/log/messages.  You should see two messages in the log:

PInS data found at offset XXXXX
PInS memtype = X

On the GXT135p card I get "31168" and "5".  The first value is irrelevant,
but it's presence lets me know that the PInS data was actually found.  On a
GXT130p, the second value should be 3.  Since I don't have access to that
hardware, if someone can verify that, I will submit a follow-on patch that
rips out all the memtype parameter stuff.

28254d439b [PATCH] vga text console and stty cols/rows
Some people use 66-cells braille devices for reading the console, and hence
would like to reduce the width of the screen by using:

stty cols 66

However, the vga text console doesn't behave correctly: the 14 first
characters of the second line are put on the right of the first line and so
forth.

Here is a patch to correct that.  It corrects the disp_end and offset
registers of the vga board on console resize and console switch.

On usual screens, you then correctly get a right and/or bottom blank
margin.  On some laptop panels, the output is resized so that text actually
gets magnified, which can be great for some people (see
http://dept-info.labri.fr/~thibault/ls.jpg ).

aac51f09d9 [PATCH] w100fb: Rewrite for platform independence
The code w100fb was based on was horribly Sharp SL-C7x0 specific and there
was little else that could be done as I had no access to anything else with
a w100 in it.  There is no real documentation about this chipset available.

Ian Molton has access to other platforms with the w100 (Toshiba e-series)
and so between us, we've improved w100fb and made it platform independent.
Ian Molton also added support for the very similar w3220 and w3200
chipsets.

There are a lot of changes here and it nearly amounts to a rewrite of the
driver but it has been extensively tested and is being used in preference
to the original driver in the Zaurus community.  I'd therefore like to
update the mainline code to reflect this.

1684a98430 [PATCH] I2C: Kill i2c_algorithm.id (6/7)
In theory, there should be no more users of I2C_ALGO_* at this point.
However, it happens that several drivers were using I2C_ALGO_* for
adapter ids, so we need to correct these before we can get rid of all
the I2C_ALGO_* definitions.

Note that this also fixes a bug in media/video/tvaudio.c:

	/* don't attach on saa7146 based cards,
	   because dedicated drivers are used */
	if ((adap->id & I2C_ALGO_SAA7146))
		return 0;

This test was plain broken, as it would succeed for many more adapters
than just the saa7146: any those id would share at least one bit with
the saa7146 id. We are really lucky that the few other adapters we want
this driver to work with did not fulfill that condition.

3edea4833a [PATCH] intelfb/fbdev: Save info->flags in a local variable
Reported by: Pavel Kysilka (Bugzilla Bug 5059)

The intelfb driver does not keep resolution set with fbset after
switching to anot console and back.

Steps to reproduce:

  initial options: tty1,tty2 - 1024x768-60
  1) tty1 - fbset after booting (1024x768-60)
  2) tty1 - fbset 800x600-100
  tty1: 800x600-100
  3) swith to tty2, swith to tty1
  tty1: 1024x768-60 (the same resolution as default from kernel booting)

This bug is caused by intelfb unintentionally destroying info->flags in
set_par(). Therefore the flag, FBINFO_MISC_USEREVENT used to notify
fbcon of a mode change was cleared causing the above problem. This bug
though is not intelfb specific, as other drivers may also be affected.

The fix is to save info->flags in a local variable before calling any
of the driver hooks.  A more definitive fix (for post 2.6.13) is to
separate info->flags into one that is set by the driver and another that
is set by core fbdev/fbcon.

"At boot time the screen appears moved to the mid right portion of the actual

His particular hardware has a display with an unusual dimension (1920x1200) but
unfortunately has no EDID block. None of the entries in the global mode
database is correct for this particular display, and it particularly has
difficulty scaling up 640x480 (the default startup mode of nvidiafb) to
1920x1200 which causes the above described problem.

1, Add 1920x1200 to the global mode database.

2. Let nvidiafb base the startup mode from the flatpanel dimensions only if the
  EDID block is absent, no boot mode parameter is specified by the user, and
  a flatpanel/LCD display is attached.

Most important is CRTC register 2f, signal quality is also improved for

This bug was explained by: Knut_Petersen

Acceleration is broken for all BLADE 3D chips for all versions of kernel
2.6 except for 32bit modes.  Most important reason is that the u32 col
parameter of the graphics engine needs the color value replicated to all

03e259a9cd [PATCH] fbdev: update info->cmap when setting cmap from user-/kernelspace.
The fb_info struct, as defined in include/linux/fb.h, contains an element
that is supposed to hold the current color map:
  struct fb_cmap cmap;            /* Current cmap */

This cmap is currently never updated when either fb_set_cmap() or
fb_set_user_cmap() are called.  As a result, info->cmap contains the
default cmap that was set by a device driver/fbcon and a userspace
application using the FBIOGETCMAP ioctl will not always get the *currently*
used color map.

The patch fixes this by making sure the cmap is copied to info->cmap after
it is set correctly.  It moves most of the code that is responsible for
setting the cmap to fb_set_cmap() and out of fb_set_user_cmap() to avoid
code-duplication.

b3d5496ea5 [PATCH] I2C: Kill address ranges in non-sensors i2c chip drivers
Some months ago, you killed the address ranges mechanism from all
sensors i2c chip drivers (both the module parameters and the in-code
address lists). I think it was a very good move, as the ranges can
easily be replaced by individual addresses, and this allowed for
significant cleanups in the i2c core (let alone the impressive size
shrink for all these drivers).

Unfortunately you did not do the same for non-sensors i2c chip drivers.
These need the address ranges even less, so we could get rid of the
ranges here as well for another significant i2c core cleanup. Here comes
a patch which does just that. Since the process is exactly the same as
what you did for the other drivers set already, I did not split this one
in parts.

A documentation update is included.

The change saves 308 bytes in the i2c core, and an average 1382 bytes
for chip drivers which use I2C_CLIENT_INSMOD, 126 bytes for those which
do not.

This change is required if we want to merge the sensors and non-sensors
i2c code (and we want to do this).

on the vga8x16 font).

This patch is non-intrusive, no options are enabled by default so most

I am placing my changes under the GPL, however, I've not seen any copyright

f18cd8f705 [PATCH] VGA to fbcon fix.
Currently when going from vgacon to fbcon the VT screenbuffer are often
different sizes.  In the case when they are different sizes a new VT
screenbuffer is allocated and the contents are copied into the new buffer.

Currently the amount copied from VGA text memory to the new screenbuf is
the size of the framebuffer console.  If the framebuffer console new VT
screen buffer is greater than the VGA text memory size then we get some of
the VGA BIOS contents as well.

This patch will only allow you to copy up to the size of VGA text memory
now.  The rest is filled with erase characters.

27f931dac9 [PATCH] s1d13xxxfb linkage fix
s1d13xxxfb_remove() is referenced from s1d13xxxfb_probe(), which is marked
__devinit().  So s1d13xxxfb_remove() cannot be marked __devexit.

Does this all make sense?  Clearly the __devexit section will still be in
core when the __devinit code is run, if the driver was loaded as a module.

But I suppose that if the driver is statically linked, the __devexit section
might be dropped early in boot.  Still, we wouldn't drop __devexit prior to
initcall completion, at which point the __devinit code has all been run
anyway.

verdict: this code was legal and made sense.  Is this a generic problem, or an
arm-specific problem?

346e399b2a [PATCH] intelfb section fix
On Nov 16 2004 a change to intelfbdrv.c was commited (as part of 0.9.2 it
looks like) that added __initdata to all of the module param variables that
seems to create the opportunity for an oops.

I've recently been chasing an OOPS
(http://marc.theaimsgroup.com/?l=linux-kernel&m=111552250920370&w=2) I
created by reading every file on the /sys file system and I've traced it
back to this code in the intelfbdrv.  Though I had root privs in my initial
problem report, it turns out they are un-necessary to generate the oops -
all you've got to do is "cat /sys/module/intelfb/parameters/mode" enough
times and eventually it will oops.

This is because sysfs automatically exports all module_param declarations
to the sysfs file system..  which means those variables can be dynamically
evaluated at any later time, which of course means marking them __initdata
is a bad idea ;)..  when they happen to be char *'s it is an especially bad
idea ;).

Applying the patch below clears up the OOPS for me.

4dc3b16ba1 [PATCH] DocBook: changes and extensions to the kernel documentation
I have recompiled Linux kernel 2.6.11.5 documentation for me and our
university students again.  The documentation could be extended for more
sources which are equipped by structured comments for recent 2.6 kernels.  I
have tried to proceed with that task.  I have done that more times from 2.6.0
time and it gets boring to do same changes again and again.  Linux kernel
compiles after changes for i386 and ARM targets.  I have added references to
some more files into kernel-api book, I have added some section names as well.
 So please, check that changes do not break something and that categories are
not too much skewed.

I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
by kernel convention.  Most of the other changes are modifications in the
comments to make kernel-doc happy, accept some parameters description and do
not bail out on errors.  Changed <pid> to @pid in the description, moved some
#ifdef before comments to correct function to comments bindings, etc.

You can see result of the modified documentation build at
  http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz

Some more sources are ready to be included into kernel-doc generated
documentation.  Sources has been added into kernel-api for now.  Some more
section names added and probably some more chaos introduced as result of quick
cleanup work.

14c6f52f60 [PATCH] intelfb: Remove intelfbdrv.h
Ingo Oeser noticed that all that intelfbdrv.h contains are prototypes for
static functions - and such prototypes don't belong into header files.

This patch therefore removes drivers/video/intelfb/intelfbdrv.h and moves the
prototypes to intelfbdrv.c .

7149437669 [PATCH] fbdev: Batch cmap changes at driver level
This patch adds to the fbdev interface a set_cmap callback that allow the
driver to "batch" palette changes.  This is useful for drivers like
radeonfb which might require lenghtly workarounds on palette accesses, thus
allowing to factor out those workarounds efficiently.

a40920b42a [PATCH] vgacon: set vc_hi_font_mask correctly
When allocating a new VC with vgacon_init(), the font is shared across all
the VGA consoles.  However, the font mask was always set to the default
value of zero in visual_init(), even if we were using 512 character fonts
at the time.

Moreover, code in vgacon.c:vga_do_font_op() didn't reset the mask if the
console driver thinks it's already in 512 character mode.  This means that
to *fix* it, you'd actually have to take the console out of 512 character
mode and then set it back.

The attached sets vc_hi_font_mask in vgacon_init() for any new consoles
opened if the vgacon driver is already in 512 character mode, solving this.

This bug goes back to 2.4.18 at least, probably earlier.

82235e9170 [PATCH] ARM: Fix AMBA CLCD fb driver for 32bpp
We were supporting 24bpp.  However, the pixel organisation in
memory was 0RGB, so it was 24bpp in 32bit words.  This means
we're actually supporting 32bpp and not 24bpp.

Also, add a check to ensure that we don't exceed the available
framebuffer when changing display resolutions.

6ee7c15294 [SPARC]: TCX Framebuffer fixes
Using the same logic as the other framebuffer fixes committed in 2.6.11,
this is a set of fixes to make TCX functional on the console again. Adds
the tcx_pan_display function, sets the
all->info.var.{red,green,blue}.length values to 8, and runs fb_set_cmap.
Also looks for the correct SUNW,tcx prom value.

This patch just slipped through the cracks.

0c541b4406 [PATCH] ppc32: Fix AGP and sleep again
My previous patch that added sleep support for uninorth-agp and some AGP
"off" stuff in radeonfb and aty128fb is breaking some configs.  More
specifically, it has problems with rage128 setups since the DRI code for
these in X doesn't properly re-enable AGP on wakeup or console switch
(unlike the radeon DRM).

This patch fixes the problem for pmac once for all by using a different
approach.  The AGP driver "registers" special suspend/resume callbacks with
some arch code that the fbdev's can later on call to suspend and resume
AGP, making sure it's resumed back in the same state it was when suspended.
 This is platform specific for now.  It would be too complicated to try to
do a generic implementation of this at this point due to all sort of weird
things going on with AGP on other architectures.  We'll re-work that whole
problem cleanly once we finally merge fbdev's and DRI.

In the meantime, please apply this patch which brings back some r128 based
laptops into working condition as far as system sleep is concerned.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
