+ help
+ This option enables the Linux bootsplash screen.
+
+ The bootsplash is a full-screen logo or animation indicating a
+ booting system. It replaces the classic scrolling text with a
+ graphical alternative, similar to other systems.
+
+ Since this is technically implemented as a hook on top of fbcon,
+ it can only work if the FRAMEBUFFER_CONSOLE is enabled and a
+ framebuffer driver is active. Thus, to get a text-free boot,
+ the system needs to boot with vesafb, efifb, or similar.
+
+ Once built into the kernel, the bootsplash needs to be enabled
+ with bootsplash.enabled=1 and a splash file needs to be supplied.
+
+ Further documentation can be found in:
+ Documentation/fb/bootsplash.txt
+
+ If unsure, say N.
+ This is typically used by distributors and system integrators.

+====================
+The Linux bootsplash
+====================
+
+:Date: November, 2017
+:Author: Max Staudt <mstaudt@suse.de>
+
+
+The Linux bootsplash is a graphical replacement for the '``quiet``' boot
+option, typically showing a logo and a spinner animation as the system starts.
+
+Currently, it is a part of the Framebuffer Console support, and can be found
+as ``CONFIG_BOOTSPLASH`` in the kernel configuration. This means that as long
+as it is enabled, it hijacks fbcon's output and draws a splash screen instead.
+
+Purely compiling in the bootsplash will not render it functional - to actually
+render a splash, you will also need a splash theme file. See the example
+utility and script in ``tools/bootsplash`` for a live demo.
+
+
+
+Motivation
+==========
+
+- The '``quiet``' boot option only suppresses most messages during boot, but
+ errors are still shown.
+
+- A user space implementation can only show a logo once user space has been
+ initialized far enough to allow this. A kernel splash can display a splash
+ immediately as soon as fbcon can be displayed.
+
+- Implementing a splash screen in user space (e.g. Plymouth) is problematic
+ due to resource conflicts.
+
+ For example, if Plymouth is keeping ``/dev/fb0`` (provided via vesafb/efifb)
+ open, then most DRM drivers can't replace it because the address space is
+ still busy - thus leading to a VRAM reservation error.
+
+ See: https://bugzilla.opensuse.org/show_bug.cgi?id=980750
+
+
+
+Command line arguments
+======================
+
+``bootsplash.bootfile``
+ Which file in the initramfs to load.
+
+ The splash theme is loaded via request_firmware(), thus to load
+ ``/lib/firmware/bootsplash/mytheme`` pass the command line:
+
+ ``bootsplash.bootfile=bootsplash/mytheme``
+
+ Note: The splash file *has to be* in the initramfs, as it needs to be
+ available when the splash is initialized early on.
+
+ Default: none, i.e. a non-functional splash, falling back to showing text.
+
+
+
+sysfs run-time configuration
+============================
+
+``/sys/devices/platform/bootsplash.0/enabled``
+ Enable/disable the bootsplash.
+ The system boots with this set to 1, but will not show a splash unless
+ a splash theme file is also loaded.
+
+
+
+Kconfig
+=======
+
+``BOOTSPLASH``
+ Whether to compile in bootsplash support
+ (depends on fbcon compiled in, i.e. ``FRAMEBUFFER_CONSOLE=y``)
+
+
+
+Bootsplash file format
+======================
+
+A file specified in the kernel configuration as ``CONFIG_BOOTSPLASH_FILE``
+or specified on the command line as ``bootsplash.bootfile`` will be loaded
+and displayed as soon as fbcon is initialized.
+
+
+Main blocks
+-----------
+
+There are 3 main blocks in each file:
+
+ - one File header
+ - n Picture headers
+ - m (Blob header + payload) blocks
+
+
+Structures
+----------
+
+The on-disk structures are defined in
+``drivers/video/fbdev/core/bootsplash_file.h`` and represent these blocks:
+
+ - ``struct splash_file_header``
+
+ Represents the file header, with splash-wide information including:
+
+ - The magic string "``Linux bootsplash``" on big-endian platforms
+ (the reverse on little endian)
+ - The file format version (for incompatible updates, hopefully never)
+ - The background color
+ - Number of picture and blob blocks
+ - Animation speed (we only allow one delay for all animations)
+
+ The file header is followed by the first picture header.
+
+
+ - ``struct splash_picture_header``
+
+ Represents an object (picture) drawn on screen, including its immutable
+ properties:
+ - Width, height
+ - Positioning relative to screen corners or in the center
+ - Animation, if any
+ - Animation type
+ - Number of blobs
+
+ The picture header is followed by another picture header, up until n
+ picture headers (as defined in the file header) have been read. Then,
+ the (blob header, payload) pairs follow.
+
+
+ - ``struct splash_blob_header``
+ (followed by payload)
+
+ Represents one raw data stream. So far, only picture data is defined.
+
+ The blob header is followed by a payload, then padding to n*16 bytes,
+ then (if further blobs are defined in the file header) a further blob
+ header.
+
+
+Alignment
+---------
+
+The bootsplash file is designed to be loaded into memory as-is.
+
+All structures are a multiple of 16 bytes long, all elements therein are
+aligned to multiples of their length, and the payloads are always padded
+up to multiples of 16 bytes. This is to allow aligned accesses in all
+cases while still simply mapping the structures over an in-memory copy of
+the bootsplash file.
+
+
+Further information
+-------------------
+
+Please see ``drivers/video/fbdev/core/bootsplash_file.h`` for further
+details and possible values in the file.
+
+
+
+Hooks - how the bootsplash is integrated
+========================================
+
+``drivers/video/fbdev/core/fbcon.c``
+ ``fbcon_init()`` calls ``bootsplash_init()``, which loads the default
+ bootsplash file or the one specified on the kernel command line.
+
+ ``fbcon_switch()`` draws the bootsplash when it's active, and is also
+ one of the callers of ``set_blitting_type()``.
+
+ ``set_blitting_type()`` calls ``fbcon_set_dummyops()`` when the
+ bootsplash is active, overriding the text rendering functions.
+
+ ``fbcon_cursor()`` will call ``bootsplash_disable()`` when an oops is
+ being printed in order to make a kernel panic visible.
+
+``drivers/video/fbdev/core/dummyblit.c``
+ This contains the dummy text rendering functions used to suppress text
+ output while the bootsplash is shown.
+
+``drivers/tty/vt/keyboard.c``
+ ``kbd_keycode()`` can call ``bootsplash_disable()`` when the user
+ presses ESC or F1-F12 (changing VT). This is to provide a built-in way
+ of disabling the splash manually at any time.
+
+
+
+FAQ: Frequently Asked Questions
+===============================
+
+I want to see the log! How do I show the log?
+---------------------------------------------
+
+Press ESC while the splash is shown, or remove the ``bootsplash.bootfile``
+parameter from the kernel cmdline. Without that parameter, the bootsplash
+will boot disabled.
+
+
+Why use FB instead of modern DRM/KMS?
+-------------------------------------
+
+This is a semantic problem:
+ - What memory to draw the splash to?
+ - And what mode will the screen be set to?
+
+Using the fbdev emulation solves these issues.
+
+Let's start from a bare KMS system, without fbcon, and without fbdev
+emulation. In this case, as long as userspace doesn't open the KMS
+device, the state of the screen is undefined. No framebuffer is
+allocated in video RAM, and no particular mode is set.
+
+In this case, we'd have to allocate a framebuffer to show the splash,
+and set our mode ourselves. This either wastes a screenful of video RAM
+if the splash is to co-exist with the userspace program's own allocated
+framebuffer, or there is a flicker as we deactivate and delete the
+bootsplash's framebuffer and hand control over to userspace. Since we
+may set a different mode than userspace, we'd also have flicker due
+to mode switching.
+
+This logic is already contained in every KMS driver that performs fbdev
+emulation. So we might as well use that. And the correct API to do so is
+fbdev. Plus, we get compatibility with old, pure fbdev drivers for free.
+With the fbdev emulation, there is *always* a well-defined framebuffer
+to draw on. And the selection of mode has already been done by the
+graphics driver, so we don't need to reinvent that wheel, either.
+Finally, if userspace decides to use /dev/fbX, we don't have to worry
+about wasting video RAM, either.
+
+
+Why is the bootsplash integrated in fbcon?
+------------------------------------------
+
+Right now, the bootsplash is drawn from within fbcon, as this allows us
+to easily know *when* to draw - i.e. when we're safe from fbcon and
+userspace drawing all over our beautiful splash logo.
+
+Separating them is not easy - see the to-do list below.
+
+
+
+TO DO list for future development
+=================================
+
+Second enable/disable switch for the system
+-------------------------------------------
+
+It may be helpful to differentiate between the system and the user
+switching off the bootsplash. Thus, the system may make it disappear and
+reappear e.g. for a password prompt, yet once the user has pressed ESC,
+it could stay gone.
+
+
+Fix buggy DRM/KMS drivers
+-------------------------
+
+Currently, the splash code manually checks for fbdev emulation provided by
+the ast, cirrus, and mgag200 DRM/KMS drivers.
+These drivers use a manual mechanism similar to deferred I/O for their FB
+emulation, and thus need to be manually flushed onto the screen in the same
+way.
+
+This may be improved upon in several ways:
+
+1. Changing these drivers to expose the fbdev BO's memory directly, like
+ bochsdrmfb does.
+2. Creating a new fb_ops->fb_flush() API to allow the kernel to flush the
+ framebuffer once the bootsplash has been drawn into it.
+
+
+Separating from fbcon
+---------------------
+
+Separating these two components would yield independence from fbcon being
+compiled into the kernel, and thus lowering code size in embedded
+applications.
+
+To do this cleanly will involve a clean separation of users of an FB device
+within the kernel, i.e. fbcon, bootsplash, and userspace. Right now, the
+legacy fbcon code and VT code co-operate to switch between fbcon and
+userspace (by setting the VT into KD_GRAPHICS mode). Installing a muxer
+between these components ensues refactoring of old code and checking for
+correct locking.
