-+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://github.com/alanhaggai/fbsplash
-+
-+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.

-From 9a18df7a71bfa620b1278777d64783a359d7eb4e Mon Sep 17 00:00:00 2001
-From: Thorsten Glaser <tg@mirbsd.org>
-Date: Sun, 4 May 2014 01:37:54 +0200
-Subject: [PATCH] mount tmpfs-as-rootfs (initramfs) with -o
- nr_blocks=0,nr_inodes=0
-
-I would have preferred to write this patch to be able to pass
-rootflags=nr_blocks=0,nr_inodes=0 on the kernel command line,
-and then hand these rootflags over to the initramfs (tmpfs)
-mount in the same way the kernel hands them over to the block
-device rootfs mount. But at least the Debian/m68k initrd also
-parses $rootflags from the environment and adds it to the call
-to the user-space mount for the eventual root device, which
-would make the kernel command line rootflags option be used in
-both places (tmpfs and e.g. ext4) which is guaranteed to error
-out in at least one of them.
-
-This change is intended to aid people in a setup where the
-initrd is the final root filesystem, i.e. not mounted over.
-This is especially useful in automated tests running on qemu
-for boards with constrained memory (e.g. 64 MiB on sh4).
-
-Considering that the initramfs is normally emptied out then
-overmounted, this change is probably safe for setups where
-initramfs just hosts early userspace, too, since the tmpfs
-backing it is not accessible any more later on, AFAICT.

-+ Older-style on-NAND data format has a "pageStatus" byte to record
-+ chunk/page state. This byte is zero when the page is discarded.
-+ Choose this option if you have existing on-NAND data using this
-+ format that you need to continue to support. New data written
-+ also uses the older-style format. Note: Use of this option
-+ generally requires that MTD's oob layout be adjusted to use the
