Subject: xen: clean up domain mode predicates

There are four operating modes Xen code may find itself running in:
 - native
 - hvm domain
 - pv dom0
 - pv domU

Clean up predicates for testing for these states to make them more consistent.

Subject: [ARM] 5209/1: metronomefb: changes to use platform framebuffer

These changes are used in order to support the use of the framebuffer
provided by the platform device driver rather than to directly allocate one.
Other changes are cleanup to error handling and order of release.

From 922613436ae562a2903698f3a6e16998382a549d Mon Sep 17 00:00:00 2001

Subject: [ARM] 5200/1: am200epd: use fb notifiers and gpio api

The original am200epd driver was designed with bad assumptions. It
manipulated GPSR/GPLR registers directly. It relied on direct access to the
pxa LCDC registers which have since conflicted with commit
ce4fb7b892a6d6c6a0f87366b26fd834d2923dd7 . This patch moves it into mach-pxa
and overhauls it to use a fb obtained through fb notifiers. It now uses the
generic GPIO api.

Subject: x86 setup: remove remnants of CONFIG_VIDEO_SELECT (read: vga=)

Impact: cleanup

Video mode selection became always possible in 2.6.23-rc1 after i386 setup
code rewrite in C.

Regardless, VIDEO_SELECT is stupid config option because it affects only
kernel setup code, not code which always stays in memory.

vga= always possible now which is good.

Subject: [ARM] omap: Fix IO_ADDRESS() macros

OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies
for use with __raw_{read|write}* for accessing registers.  Therefore,
these macros should return (void __iomem *) cookies, not integer values.

Doing this improves typechecking, and means we can find those places
where, eg, DMA controllers are incorrectly given virtual addresses to
DMA to, or physical addresses are thrown through a virtual to physical
address translation.

Subject: atmel_lcdfb: disable LCD and DMA engines when suspending

When suspending the system with atmel_lcdfb enabled, I sometimes see
this:

	atmel_lcdfb atmel_lcdfb.0: FIFO underflow 0x10

Which can be explained by the fact that we're not stopping the LCD
controller and its DMA engine when suspending, we're just gating the
clocks to them.

There's another potential issue which may be harder to trigger but
much more nasty: If we gate the clocks at _just_ the right moment,
e.g. when the DMA engine is doing a bus transaction, we may cause the
DMA engine to violate the system bus protocol and cause a lockup.

Avoid these issues by shutting down the LCD controller before entering
suspend (and restarting it when resuming). This prevents the underrun
from happening in the first place, and prevents whatever nastiness is
happening when the bus clock stops in the middle of a DMA transfer.

Some LCD panels are capable of different resolutions, and is allowed
to change at run-time, so to make "struct lcd_device" to be able to
handle mode change events here.

Subject: lcd: add SPI-based LCD and backlight driver for SHARP corgi/spitz

The driver is based on different source files including corgi_ssp.c,
corgi_lcd.c and corgi_bl.c, previously authored by Richard Purdie
and many others.

The LCD and Backlight device actually share the same SPI device, so
they are made into this single driver.

Subject: lcd: add corgibl_limit_intensity() to corgi_lcd

This is not generic enough, added here for backward compatibility.
And make this an individual commit so future revert will be a bit
easier.

Subject: fbcon: fix monochrome color value calculation

Commit 22af89aa0c0b4012a7431114a340efd3665a7617 ("fbcon: replace mono_col
macro with static inline") changed the order of operations for computing
monochrome color values.  This generates 0xffff000f instead of 0x0000000f
for a 4 bit monochrome color, leading to image corruption if it is passed
to cfb_imageblit or other similar functions.  Fix it up.

Subject: fbdev: fix recursive notifier and locking when fbdev console is
 blanked

Fix infinite recursive notifier in the fbdev layer.  This causes recursive
locking.  Dmitry Baryshkov found the problem and confirmed that the patch
fixes the bug.

After doing
# echo 1 > /sys/class/graphics/fb0/blank
I got the following in my kernel log:

=============================================

but task is already holding lock:

other info that might help us debug this:

Subject: cg6: disable cursor when leaving graphics mode

On sparc32 debian etch, the cursor is not disabled
when leaving X windows.  This patch disables the
cursor when leaving graphics mode just like the
ffb driver.

Subject: leo: disable cursor when leaving graphics mode

On sparc32 debian etch, the cursor is not disabled
when leaving X windows.  This patch disables the
cursor when leaving graphics mode just like the
ffb driver.

Use new MODULE_DEVICE_TABLE(dmi, ...) facility. There's no need for
every driver to screw it up for themselves, when the alias can be
generated automatically.

Subject: Revert "vt: fix background color on line feed"

This reverts commit c9e587abfdec2c2aaa55fab83bcb4972e2f84f9b, and the
subsequent commits that fixed it up:

 - afa9b649 "fbcon: prevent cursor disappearance after switching to 512
   character font"

 - d850a2fa "vt/fbcon: fix background color on line feed"

 - 7fe3915a "vt/fbcon: update scrl_erase_char after 256/512-glyph font
   switch"

by request of Alan Cox. Quoth Alan:
  "Unfortunately it's wrong and its been causing breakages because
   various apps like ncurses expect our previous (and correct)
   behaviour."

Alexander sent out a similar patch.

Subject: omap drivers: switch to standard GPIO calls

This updates most of the OMAP drivers which are in mainline to switch to
using the cross-platform GPIO calls instead of the older OMAP-specific
ones.

This is all fairly brainless/obvious stuff.  Probably the most interesting
bit is to observe that the omap-keypad code seems to now have a portable
core that could work with non-OMAP matrix keypads.  (That would improve
with hardware IRQ debouncing enabled, of course...)

From b3a45d8e5d9049c3a47b3f97405b4123bef5155b Mon Sep 17 00:00:00 2001
From: Joseph Chan <JosephChan@via.com.tw>
Date: Wed, 15 Oct 2008 22:03:29 -0700
Subject: viafb: viafbdev.c (update)

Remove the macro MMIO_OUT32, and replace it with writel() function.
And replace "u32" with "unsigned long" in writel() function (original
MMIO_OUT32 marco) for avoiding warning message in 64bit OS.

Subject: intelfb: support 945GME (as used in ASUS Eee 901)

Add support for Intel's 945GME graphics chip to the intelfb driver.  I
have assumed that the 945GME is identical to the already-supported 945GM
apart from its PCI IDs; this is based on a quick look at the X driver for
these chips which seems to treat them identically.

The 945GME is used in the ASUS Eee 901, and I coded this in the hope that
I'd be able to use it to get a console at the native 1024x600 resolution
which is not known to the BIOS.  I realised too late that the intelfb
driver does not support mode changing on laptops, so it won't be any
use for me.

Subject: cirrusfb: drop clock fields from cirrusfb_regs structure

Move call to pixclock calculation into the cirrusfb_set_par_foo().  It
makes copy of clock registers redundant.

Simplify clock calculations further.

Subject: cirrusfb: fix 16bpp modes

The 16bpp mode did not work on the Cirrus cards as the visual type was set
to DIRECTCOLOR instead of TRUECOLOR.  The Alpine family used one incorrect
register setting so this 16bpp modes generated wrong horizontal frequency.

Subject: cirrusfb: do not change MCLK for Alpine chips

A memory clock value (MCLK) is changed to a minimum required by a current
mode bandwidth.  This usually lowers the MCLK to its minimum (50 MHz) thus
decreasing the card performance.  Just leave the MCLK value set by card
BIOS.

The CL-GD5446 Technical Reference Manual point 9.9.1.3 states that if a
pixclock value is close (~1%) to the MCLK or MCLK/2 this may result in a
jitter on the screen.  A countermeasure is to use the MCLK as pixclock
source instead of a VCLK.  The patch implements this as well.

Subject: efifb/imacfb consolidation + hardware support

Remove imacfb entirely, merging its DMI table into the (otherwise very
similar) efifb driver.  This also adds hardware support for many of the
newer Intel Apple hardware.  This has been fairly well tested; we've been
shipping it in Fedora for some time.

Subject: radeonfb: misc cleanup of engine and dst cache handling

Fix a couple of incomplete tests of the chip families in the engine
init/reset code and proper initialization of the destination cache mode.
The result should better match what the latest X radeon driver does.

Subject: radeonfb: accelerate imageblit and other improvements

Implement support for HW color expansion of 1bpp images, along with some
improvements to the FIFO handling and other accel operations.

The offset fixup code is now unnecessary as the fbcon core will call our
set_par upon switch back from KD_GRAPHICS before anything else happens.  I
removed it as it would slow down accel operations.

The fifo wait has been improved to avoid hitting the HW register as often,
and the various accel ops are now performing better caching of register
values.

Overall, this improve accel performances.  The imageblit acceleration does
result in a small overall regression in performances on some machines (on
the order of 5% on some x86), probably becaus the SW path provides a
better bus utilisation, but I decided to ingnore that as the performances
is still very good, and on the other hand, some machines such as some
sparc64 get a 3 fold performance improvement.

Subject: uvesafb: don't treat mode info retrieval failures as errors

Some BIOSes return error codes when queried for information about
modes from their own modelist.  uvesafb treats this as an error
case and bails out.

Change this behavior so that broken modes do not prevent the driver
from working.  Only the failure to retrieve information about any
usable video mode is considered to be an error case.

The current EDID parser in the linux kernel ignores interlace modes.  The
patch looks for the edid interlace flag and adjusts the vertical

Subject: vgacon: vgacon_scrolldelta simplification

There's no point in checking diff == c->vc_rows, because it can be true
only when count == 0, but we already checked that.  Additionally move
variables used only in one block to this block.

Subject: fbdev: ignore VESA modes if framebuffer does not support them

Currently, it is possible to set a graphics VESA mode at boot time via the
vga= parameter even when no framebuffer driver supporting this is
configured.  This could lead to the system booting with a black screen,
without a usable console.

Fix this problem by only allowing to set graphics modes at boot time if a
supporting framebuffer driver is configured.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Epson s1d13xxx hardware is common in many handhelds, but our driver is
currently locked to a single chip revision.  This patch adds an array of
known to work revisions (which can be extended).

WARNING: drivers/video/carminefb.o(.text+0x81b): Section mismatch in reference from the function alloc_carmine_fb() to the variable .devinit.data:carminefb_fix

The function alloc_carmine_fb() references the variable __devinitdata
carminefb_fix.  This is often because alloc_carmine_fb lacks a
__devinitdata annotation or the annotation of carminefb_fix is wrong.

Subject: fbcon_set_all_vcs: fix kernel crash when switching the rotated
 consoles

echo 3 >> /sys/class/graphics/fbcon/rotate_all, then switch to another
console. Result:

Because fbcon_set_all_vcs()->FBCON_SWAP() uses display->rotate == 0 instead
of fbcon_ops->rotate, and vc_resize() has no effect because it is called with
new_cols/rows == ->vc_cols/rows.

Tested on 2.6.26.5-45.fc9.x86_64, but
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git seems to
have the same problem.
