|

+ 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:

+====================
|
||||
+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
|
||||

|
||||
+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.
