Each multipath instance can use a Hardware Handler with hooks for the
particular hardware you're using.

This patch provides the hw_handler infrastructure.

So far 3 hooks are available:

  A status function invoked by device-mapper table and status requests.

  An initialisation function called when a Priority Group is selected for
  use but before any I/O is sent to it.  This function should return straight
  away, and I/O is queued until dm_pg_init_complete() is called indicating
  whether or not the initialisation was successful.  The are three error
  flags, any or all of which may be set: MP_FAIL_PATH, MP_BYPASS_PG,
  MP_ERROR_IO.

  An error handler which gets the opportunity to decode any error that a bio
  generated.  Patches are pending to make scsi error details available for
  dm_scsi_err_handler() to decode.

A very basic path selector: round-robin.

It uses in turn each path that has not been disabled.

By default, it instructs core multipath to use each path it supplies for 1000
bios, but a different repeat_count can be set against any path to provide
primitive load-balancing across unequal paths.

The core device-mapper multipath and path-selector code.

Paths are grouped into an ordered list of Priority Groups.  Each Priority
Group has a Path Selector which chooses which of the Priority Group's paths is
to be used for each bio e.g.  according to some load-balancing algorithm.  If
a bio generates an error, the path that it used gets disabled and an
alternative path is tried.  If all the paths in a Priority Group fail, another
Priority Group is selected.

There are management commands fail_path and reinstate_path.  A path tester
(currently implemented in userspace) is responsible for monitoring paths that
have failed and reinstating them should they come back.

Other management commands can be use to switch immediately to a specified
Priority Group or to disable a particular Priority Group so it will only be
tried after there are no more left.

As a last resort there is an option to 'queue_if_no_path' which queues I/O if
all paths have failed e.g.  temporarily during a firmware update or if the
userspace daemon is slow reinstating paths.

The userspace multipath tools are available at:

From: Alasdair G Kergon <agk@redhat.com>

  Don't requeue I/O repeatedly if there are no paths left and the device is
  in the process of being suspended, or else the suspend can never complete.

So you remember all those weird lockups at boot that happened in late
2.6.11-rc with radeonfb.  I posted a "workaround" which just moved code
around a bit and it appeared to work.  I finally got some real infos about
the problem from ATI, and it seems my "workaround" is not very safe and
there are other potential issues realted to HW bugs when accessing the PLL
registers.

This patch implements all of these workarounds (and puts back the code
where it was before my previous fix).

we found several bugs in framebuffer console code in recent kernels.

1. The escape sequence '\033[?25l' does not work (should disable cursor).

2. When scrolling console using Shift-PgUp with cursor in the upper half
   part of the screen, cursor position is not updated.

3. If cursor is placed at some character and console is scrolled using
   Shift-PgUp, that character remains on the screen.

Also added a new event, FB_EVENT_NEW_MODELIST, sent by fbmem, and captured by

This is a first pass at adding two new sysfs attributes to
/sys/class/graphics/fb0 for setting modes.  There are two attributes: modes
which contains a list of valid modes, and mode which is the current mode.  To
switch modes echo one of the entries from the modes list to the mode
attribute.

The D,V,S on the modes represents Detailed, Vesa, Standard from the DDC info.

modes is root writable.  It can also be used to set the list of modes.  For
example a /etc file could add modes that are not in the monitor's DDC.

mode is user writable.  PAM would set ownership of mode at user login time.
This provides a safe way for a user to set the mode without being root.  You
can only set the mode to one of the modes on the list.

This patch adds suspend/resume support to the Apple UniNorth AGP bridge to
make sure AGP is properly disabled when the machine goes to sleep.  Without
this, the r300 based laptops will fail to wakeup from sleep when using the
new experimental r300 DRI driver.  It should also improve reliablility in
general with other chips.

Unfortunately, uninorth-agp is just a "sibling" of the video chip on the
PCI bus, and thus ends up beeing called either before the video chip
suspend routine, or after, depending on the HW layout or other random
things.

To make sure the device side of AGP is always disabled first and that we
never touch the device after having put it into D2 state (which can be
deadly), I also need the separate patch to radeonfb and aty128fb which will
make them disabled their own side if not already done by the bridge driver.

  From Ulrich Eckhardt:

   * removed trailing whitespace
   * use helper function for common bitwise operations
   * fixed several cases where either the wrong mask was used for bitops
     or the mask was computed falsely, messing up <32 BPP support
   * added self-tests for bitcpy_rev() algorithm in module-init function
   * no need to use explicitly sized integers in some cases
   * added a few comments where things weren't obvious to me

  I tested these changes on an Au1100 based board, using the patches to its
  framebuffer code that were posted here by Christian Pellegrin[1]. I had this
  code working both on a 16BPP color LCD and a 4BPP monochrome one.

Because nVidia keeps pumping out new graphics chipsets, it is becoming
harder to add support for these with the old rivafb code.  Currently, rivafb
can properly support NV_ARCH_20 chipsets and older.

Instead of rewriting rivafb to support the latest chipsets, I've decided to
write a new driver, called nvidiafb.  The aim is to closely follow Xorg
development.

Currently, this driver is based on the most recent CVS Xorg nv driver. Main

  - console acceleration for all chipsets
  - uses DMA instead of PIO
  - better LCD/digital output support
  - better monitor detection
  - support for Riva128 will be dropped as it cannot do DMA, rivafb
    will remain as the driver for this chipset

It should work with Xorg/XFree86 nv driver, but as with rivafb, is not
compatible with the proprietary nvidia driver.

Once the code becomes stable, rivafb code will be trimmed to only support the
Riva128 and perhaps some of the older chipsets.  The code has been tested on
several nVidia graphics card on x86 and x86_64.  I'm still waiting for
feedback from Guido Guenther regarding ppc.

This need not go to mainline immediately, as I would prefer the code to
receive rigorous testing in the mm tree.

  Attached is a patch (against 2.6.10) for a framebuffer driver for the
  Geode family of processors.  It does not use AMD's horrible Durango API.
   It is, however, rather feature incomplete at the moment.

          * Only Geode GX1 (with CS5530 companion chip) is supported.
          * Tested resolutions: 640x480 to 1280x1024.
          * Supported bit depths: 8 bit palette, 16 bit RGB 5-6-5.
          * CRT output only.
          * No accelerated features.
          * Compression is not enabled.
          * flat panel support (panel=<x>x<y> option). (Only one 640x480 panel
            has been tested though.)
          * blank function for display blanking/powersaving.
          * crt=<n> option to enable/disable the CRT output.
