+What is it?
+-----------
+
+The framebuffer decorations are a kernel feature which allows displaying a 
+background picture on selected consoles.
+
+What do I need to get it to work?
+---------------------------------
+
+To get fbcondecor up-and-running you will have to:
+ 1) get a copy of splashutils [1] or a similar program
+ 2) get some fbcondecor themes
+ 3) build the kernel helper program
+ 4) build your kernel with the FB_CON_DECOR option enabled.
+
+To get fbcondecor operational right after fbcon initialization is finished, you
+will have to include a theme and the kernel helper into your initramfs image.
+Please refer to splashutils documentation for instructions on how to do that.
+
+[1] The splashutils package can be downloaded from:
+    http://dev.gentoo.org/~spock/projects/splashutils/
+
+The userspace helper
+--------------------
+
+The userspace fbcondecor helper (by default: /sbin/fbcondecor_helper) is called by the
+kernel whenever an important event occurs and the kernel needs some kind of
+job to be carried out. Important events include console switches and video
+mode switches (the kernel requests background images and configuration
+parameters for the current console). The fbcondecor helper must be accessible at
+all times. If it's not, fbcondecor will be switched off automatically.
+
+It's possible to set path to the fbcondecor helper by writing it to
+/proc/sys/kernel/fbcondecor.
+
+*****************************************************************************
+
+The information below is mostly technical stuff. There's probably no need to
+read it unless you plan to develop a userspace helper.
+
+The fbcondecor protocol
+-----------------------
+
+The fbcondecor protocol defines a communication interface between the kernel and
+the userspace fbcondecor helper.
+
+The kernel side is responsible for:
+
+ * rendering console text, using an image as a background (instead of a
+   standard solid color fbcon uses),
+ * accepting commands from the user via ioctls on the fbcondecor device,
+ * calling the userspace helper to set things up as soon as the fb subsystem 
+   is initialized.
+
+The userspace helper is responsible for everything else, including parsing
+configuration files, decompressing the image files whenever the kernel needs
+it, and communicating with the kernel if necessary.
+
+The fbcondecor protocol specifies how communication is done in both ways:
+kernel->userspace and userspace->helper.
+  
+Kernel -> Userspace
+-------------------
+
+The kernel communicates with the userspace helper by calling it and specifying
+the task to be done in a series of arguments.
+
+The arguments follow the pattern:
+<fbcondecor protocol version> <command> <parameters>
+
+All commands defined in fbcondecor protocol v2 have the following parameters:
+ virtual console
+ framebuffer number
+ theme
+
+Fbcondecor protocol v1 specified an additional 'fbcondecor mode' after the
+framebuffer number. Fbcondecor protocol v1 is deprecated and should not be used.
+
+Fbcondecor protocol v2 specifies the following commands:
+
+getpic
+------
+ The kernel issues this command to request image data. It's up to the 
+ userspace  helper to find a background image appropriate for the specified 
+ theme and the current resolution. The userspace helper should respond by 
+ issuing the FBIOCONDECOR_SETPIC ioctl.
+
+init
+----
+ The kernel issues this command after the fbcondecor device is created and
+ the fbcondecor interface is initialized. Upon receiving 'init', the userspace
+ helper should parse the kernel command line (/proc/cmdline) or otherwise
+ decide whether fbcondecor is to be activated.
+
+ To activate fbcondecor on the first console the helper should issue the
+ FBIOCONDECOR_SETCFG, FBIOCONDECOR_SETPIC and FBIOCONDECOR_SETSTATE commands,
+ in the above-mentioned order.
+
+ When the userspace helper is called in an early phase of the boot process
+ (right after the initialization of fbcon), no filesystems will be mounted.
+ The helper program should mount sysfs and then create the appropriate
+ framebuffer, fbcondecor and tty0 devices (if they don't already exist) to get
+ current display settings and to be able to communicate with the kernel side.
+ It should probably also mount the procfs to be able to parse the kernel
+ command line parameters.
+
+ Note that the console sem is not held when the kernel calls fbcondecor_helper
+ with the 'init' command. The fbcondecor helper should perform all ioctls with
+ origin set to FBCON_DECOR_IO_ORIG_USER.
+
+modechange
+----------
+ The kernel issues this command on a mode change. The helper's response should
+ be similar to the response to the 'init' command. Note that this time the
+ console sem is held and all ioctls must be performed with origin set to
+ FBCON_DECOR_IO_ORIG_KERNEL.
+
+
+Userspace -> Kernel
+-------------------
+
+Userspace programs can communicate with fbcondecor via ioctls on the
+fbcondecor device. These ioctls are to be used by both the userspace helper
+(called only by the kernel) and userspace configuration tools (run by the users).
+
+The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL
+when doing the appropriate ioctls. All userspace configuration tools should
+use FBCON_DECOR_IO_ORIG_USER. Failure to set the appropriate value in the origin
+field when performing ioctls from the kernel helper will most likely result
+in a console deadlock.
+
+FBCON_DECOR_IO_ORIG_KERNEL instructs fbcondecor not to try to acquire the console
+semaphore. Not surprisingly, FBCON_DECOR_IO_ORIG_USER instructs it to acquire
+the console sem.
+
+The framebuffer console decoration provides the following ioctls (all defined in 
+linux/fb.h):
+
+FBIOCONDECOR_SETPIC
+description: loads a background picture for a virtual console
+argument: struct fbcon_decor_iowrapper*; data: struct fb_image*
+notes: 
+If called for consoles other than the current foreground one, the picture data
+will be ignored.
+
+If the current virtual console is running in a 8-bpp mode, the cmap substruct
+of fb_image has to be filled appropriately: start should be set to 16 (first
+16 colors are reserved for fbcon), len to a value <= 240 and red, green and
+blue should point to valid cmap data. The transp field is ingored. The fields
+dx, dy, bg_color, fg_color in fb_image are ignored as well.
+
+FBIOCONDECOR_SETCFG
+description: sets the fbcondecor config for a virtual console
+argument: struct fbcon_decor_iowrapper*; data: struct vc_decor*
+notes: The structure has to be filled with valid data.
+
+FBIOCONDECOR_GETCFG
+description: gets the fbcondecor config for a virtual console
+argument: struct fbcon_decor_iowrapper*; data: struct vc_decor*
+
+FBIOCONDECOR_SETSTATE
+description: sets the fbcondecor state for a virtual console
+argument: struct fbcon_decor_iowrapper*; data: unsigned int*
+          values: 0 = disabled, 1 = enabled.
+
+FBIOCONDECOR_GETSTATE
+description: gets the fbcondecor state for a virtual console
+argument: struct fbcon_decor_iowrapper*; data: unsigned int*
+          values: as in FBIOCONDECOR_SETSTATE
+
+Info on used structures:
+
+Definition of struct vc_decor can be found in linux/console_decor.h. It's
+heavily commented. Note that the 'theme' field should point to a string
+no longer than FBCON_DECOR_THEME_LEN. When FBIOCONDECOR_GETCFG call is
+performed, the theme field should point to a char buffer of length
+FBCON_DECOR_THEME_LEN.
+
+Definition of struct fbcon_decor_iowrapper can be found in linux/fb.h.
+The fields in this struct have the following meaning:
+
+vc: 
+Virtual console number.
+
+origin: 
+Specifies if the ioctl is performed as a response to a kernel request. The
+fbcondecor helper should set this field to FBCON_DECOR_IO_ORIG_KERNEL, userspace
+programs should set it to FBCON_DECOR_IO_ORIG_USER. This field is necessary to
+avoid console semaphore deadlocks.
+
+data: 
+Pointer to a data structure appropriate for the performed ioctl. Type of
+the data struct is specified in the ioctls description.
