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 fb splash 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 graphic
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+ o rendering console text, using an image as a background (instead of a
69+ standard solid color fbcon uses),
70+ o accepting commands from the user via ioctls on the fbsplash device,
71+ o 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 userspace
103+ helper to find a background image appropriate for the specified theme and the
104+ current resolution. The userspace helper should respond by issuing the
105+ 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.
