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.
