20     +What is it?
21     +-----------
22     +
23     +The framebuffer splash is a kernel feature that allows displaying a background
24     +picture on selected consoles.
25     +
26     +What do I need to get it to work?
27     +---------------------------------
28     +
29     +To get fb splash up-and-running you will have to:
30     + 1) get a copy of splashutils [1] or a similar program
31     + 2) get some splash themes
32     + 3) build the kernel helper program
33     + 4) build your kernel with the FB_SPLASH option enabled.
34     +
35     +To get fbsplash operational right after fbcon initialization is finished, you
36     +will have to include a theme and the kernel helper into your initramfs image.
37     +Please refer to splashutils documentation for instructions on how to do that.
38     +
39     +[1] The splashutils package can be downloaded from:
40     + http://dev.gentoo.org/~spock/projects/splashutils/
41     +
42     +The userspace helper
43     +--------------------
44     +
45     +The userspace splash helper (by default: /sbin/splash_helper) is called by the
46     +kernel whenever an important event occurs and the kernel needs some kind of
47     +job to be carried out. Important events include console switches and video
48     +mode switches (the kernel requests background images and configuration
49     +parameters for the current console). The splash helper must be accessible at
50     +all times. If it's not, fbsplash will be switched off automatically.
51     +
52     +It's possible to set path to the splash helper by writing it to
53     +/proc/sys/kernel/fbsplash.
54     +
55     +*****************************************************************************
56     +
57     +The information below is mostly technical stuff. There's probably no need to
58     +read it unless you plan to develop a userspace helper.
59     +
60     +The splash protocol
61     +-------------------
62     +
63     +The splash protocol defines a communication interface between the kernel and
64     +the userspace splash helper.
65     +
66     +The kernel side is responsible for:
67     +
68     + * rendering console text, using an image as a background (instead of a
69     + standard solid color fbcon uses),
70     + * accepting commands from the user via ioctls on the fbsplash device,
71     + * calling the userspace helper to set things up as soon as the fb subsystem
72     + is initialized.
73     +
74     +The userspace helper is responsible for everything else, including parsing
75     +configuration files, decompressing the image files whenever the kernel needs
76     +it, and communicating with the kernel if necessary.
77     +
78     +The splash protocol specifies how communication is done in both ways:
79     +kernel->userspace and userspace->helper.
80     +
81     +Kernel -> Userspace
82     +-------------------
83     +
84     +The kernel communicates with the userspace helper by calling it and specifying
85     +the task to be done in a series of arguments.
86     +
87     +The arguments follow the pattern:
88     +<splash protocol version> <command> <parameters>
89     +
90     +All commands defined in splash protocol v2 have the following parameters:
91     + virtual console
92     + framebuffer number
93     + theme
94     +
95     +Splash protocol v1 specified an additional 'fbsplash mode' after the
96     +framebuffer number. Splash protocol v1 is deprecated and should not be used.
97     +
98     +Splash protocol v2 specifies the following commands:
99     +
100     +getpic
101     +------
102     + The kernel issues this command to request image data. It's up to the
103     + userspace helper to find a background image appropriate for the specified
104     + theme and the current resolution. The userspace helper should respond by
105     + issuing the FBIOSPLASH_SETPIC ioctl.
106     +
107     +init
108     +----
109     + The kernel issues this command after the fbsplash device is created and
110     + the fbsplash interface is initialized. Upon receiving 'init', the userspace
111     + helper should parse the kernel command line (/proc/cmdline) or otherwise
112     + decide whether fbsplash is to be activated.
113     +
114     + To activate fbsplash on the first console the helper should issue the
115     + FBIOSPLASH_SETCFG, FBIOSPLASH_SETPIC and FBIOSPLASH_SETSTATE commands,
116     + in the above-mentioned order.
117     +
118     + When the userspace helper is called in an early phase of the boot process
119     + (right after the initialization of fbcon), no filesystems will be mounted.
120     + The helper program should mount sysfs and then create the appropriate
121     + framebuffer, fbsplash and tty0 devices (if they don't already exist) to get
122     + current display settings and to be able to communicate with the kernel side.
123     + It should probably also mount the procfs to be able to parse the kernel
124     + command line parameters.
125     +
126     + Note that the console sem is not held when the kernel calls splash_helper
127     + with the 'init' command. The splash helper should perform all ioctls with
128     + origin set to FB_SPLASH_IO_ORIG_USER.
129     +
130     +modechange
131     +----------
132     + The kernel issues this command on a mode change. The helper's response should
133     + be similar to the response to the 'init' command. Note that this time the
134     + console sem is held and all ioctls must be performed with origin set to
135     + FB_SPLASH_IO_ORIG_KERNEL.
136     +
137     +
138     +Userspace -> Kernel
139     +-------------------
140     +
141     +Userspace programs can communicate with fbsplash via ioctls on the fbsplash
142     +device. These ioctls are to be used by both the userspace helper (called
143     +only by the kernel) and userspace configuration tools (run by the users).
144     +
145     +The splash helper should set the origin field to FB_SPLASH_IO_ORIG_KERNEL
146     +when doing the appropriate ioctls. All userspace configuration tools should
147     +use FB_SPLASH_IO_ORIG_USER. Failure to set the appropriate value in the origin
148     +field when performing ioctls from the kernel helper will most likely result
149     +in a console deadlock.
150     +
151     +FB_SPLASH_IO_ORIG_KERNEL instructs fbsplash not to try to acquire the console
152     +semaphore. Not surprisingly, FB_SPLASH_IO_ORIG_USER instructs it to acquire
153     +the console sem.
154     +
155     +The framebuffer splash provides the following ioctls (all defined in
156     +linux/fb.h):
157     +
158     +FBIOSPLASH_SETPIC
159     +description: loads a background picture for a virtual console
160     +argument: struct fb_splash_iowrapper*; data: struct fb_image*
161     +notes:
162     +If called for consoles other than the current foreground one, the picture data
163     +will be ignored.
164     +
165     +If the current virtual console is running in a 8-bpp mode, the cmap substruct
166     +of fb_image has to be filled appropriately: start should be set to 16 (first
167     +16 colors are reserved for fbcon), len to a value <= 240 and red, green and
168     +blue should point to valid cmap data. The transp field is ingored. The fields
169     +dx, dy, bg_color, fg_color in fb_image are ignored as well.
170     +
171     +FBIOSPLASH_SETCFG
172     +description: sets the fbsplash config for a virtual console
173     +argument: struct fb_splash_iowrapper*; data: struct vc_splash*
174     +notes: The structure has to be filled with valid data.
175     +
176     +FBIOSPLASH_GETCFG
177     +description: gets the fbsplash config for a virtual console
178     +argument: struct fb_splash_iowrapper*; data: struct vc_splash*
179     +
180     +FBIOSPLASH_SETSTATE
181     +description: sets the fbsplash state for a virtual console
182     +argument: struct fb_splash_iowrapper*; data: unsigned int*
183     + values: 0 = disabled, 1 = enabled.
184     +
185     +FBIOSPLASH_GETSTATE
186     +description: gets the fbsplash state for a virtual console
187     +argument: struct fb_splash_iowrapper*; data: unsigned int*
188     + values: as in FBIOSPLASH_SETSTATE
189     +
190     +Info on used structures:
191     +
192     +Definition of struct vc_splash can be found in linux/console_splash.h. It's
193     +heavily commented. Note that the 'theme' field should point to a string
194     +no longer than FB_SPLASH_THEME_LEN. When FBIOSPLASH_GETCFG call is
195     +performed, the theme field should point to a char buffer of length
196     +FB_SPLASH_THEME_LEN.
197     +
198     +Definition of struct fb_splash_iowrapper can be found in linux/fb.h.
199     +The fields in this struct have the following meaning:
200     +
201     +vc:
202     +Virtual console number.
203     +
204     +origin:
205     +Specifies if the ioctl is performed as a response to a kernel request. The
206     +splash helper should set this field to FB_SPLASH_IO_ORIG_KERNEL, userspace
207     +programs should set it to FB_SPLASH_IO_ORIG_USER. This field is necessary to
208     +avoid console semaphore deadlocks.
209     +
210     +data:
211     +Pointer to a data structure appropriate for the performed ioctl. Type of
212     +the data struct is specified in the ioctls description.
