17 +What is it?
18 +-----------
19 +
20 +The framebuffer decorations are a kernel feature which allows displaying a
21 +background picture on selected consoles.
22 +
23 +What do I need to get it to work?
24 +---------------------------------
25 +
26 +To get fbcondecor up-and-running you will have to:
27 + 1) get a copy of splashutils [1] or a similar program
28 + 2) get some fbcondecor themes
29 + 3) build the kernel helper program
30 + 4) build your kernel with the FB_CON_DECOR option enabled.
31 +
32 +To get fbcondecor operational right after fbcon initialization is finished, you
33 +will have to include a theme and the kernel helper into your initramfs image.
34 +Please refer to splashutils documentation for instructions on how to do that.
35 +
36 +[1] The splashutils package can be downloaded from:
37 + http://dev.gentoo.org/~spock/projects/splashutils/
38 +
39 +The userspace helper
40 +--------------------
41 +
42 +The userspace fbcondecor helper (by default: /sbin/fbcondecor_helper) is called by the
43 +kernel whenever an important event occurs and the kernel needs some kind of
44 +job to be carried out. Important events include console switches and video
45 +mode switches (the kernel requests background images and configuration
46 +parameters for the current console). The fbcondecor helper must be accessible at
47 +all times. If it's not, fbcondecor will be switched off automatically.
48 +
49 +It's possible to set path to the fbcondecor helper by writing it to
50 +/proc/sys/kernel/fbcondecor.
51 +
52 +*****************************************************************************
53 +
54 +The information below is mostly technical stuff. There's probably no need to
55 +read it unless you plan to develop a userspace helper.
56 +
57 +The fbcondecor protocol
58 +-----------------------
59 +
60 +The fbcondecor protocol defines a communication interface between the kernel and
61 +the userspace fbcondecor helper.
62 +
63 +The kernel side is responsible for:
64 +
65 + * rendering console text, using an image as a background (instead of a
66 + standard solid color fbcon uses),
67 + * accepting commands from the user via ioctls on the fbcondecor device,
68 + * calling the userspace helper to set things up as soon as the fb subsystem
69 + is initialized.
70 +
71 +The userspace helper is responsible for everything else, including parsing
72 +configuration files, decompressing the image files whenever the kernel needs
73 +it, and communicating with the kernel if necessary.
74 +
75 +The fbcondecor protocol specifies how communication is done in both ways:
76 +kernel->userspace and userspace->helper.
77 +
78 +Kernel -> Userspace
79 +-------------------
80 +
81 +The kernel communicates with the userspace helper by calling it and specifying
82 +the task to be done in a series of arguments.
83 +
84 +The arguments follow the pattern:
85 +<fbcondecor protocol version> <command> <parameters>
86 +
87 +All commands defined in fbcondecor protocol v2 have the following parameters:
88 + virtual console
89 + framebuffer number
90 + theme
91 +
92 +Fbcondecor protocol v1 specified an additional 'fbcondecor mode' after the
93 +framebuffer number. Fbcondecor protocol v1 is deprecated and should not be used.
94 +
95 +Fbcondecor protocol v2 specifies the following commands:
96 +
97 +getpic
98 +------
99 + The kernel issues this command to request image data. It's up to the
100 + userspace helper to find a background image appropriate for the specified
101 + theme and the current resolution. The userspace helper should respond by
102 + issuing the FBIOCONDECOR_SETPIC ioctl.
103 +
104 +init
105 +----
106 + The kernel issues this command after the fbcondecor device is created and
107 + the fbcondecor interface is initialized. Upon receiving 'init', the userspace
108 + helper should parse the kernel command line (/proc/cmdline) or otherwise
109 + decide whether fbcondecor is to be activated.
110 +
111 + To activate fbcondecor on the first console the helper should issue the
112 + FBIOCONDECOR_SETCFG, FBIOCONDECOR_SETPIC and FBIOCONDECOR_SETSTATE commands,
113 + in the above-mentioned order.
114 +
115 + When the userspace helper is called in an early phase of the boot process
116 + (right after the initialization of fbcon), no filesystems will be mounted.
117 + The helper program should mount sysfs and then create the appropriate
118 + framebuffer, fbcondecor and tty0 devices (if they don't already exist) to get
119 + current display settings and to be able to communicate with the kernel side.
120 + It should probably also mount the procfs to be able to parse the kernel
121 + command line parameters.
122 +
123 + Note that the console sem is not held when the kernel calls fbcondecor_helper
124 + with the 'init' command. The fbcondecor helper should perform all ioctls with
125 + origin set to FBCON_DECOR_IO_ORIG_USER.
126 +
127 +modechange
128 +----------
129 + The kernel issues this command on a mode change. The helper's response should
130 + be similar to the response to the 'init' command. Note that this time the
131 + console sem is held and all ioctls must be performed with origin set to
132 + FBCON_DECOR_IO_ORIG_KERNEL.
133 +
134 +
135 +Userspace -> Kernel
136 +-------------------
137 +
138 +Userspace programs can communicate with fbcondecor via ioctls on the
139 +fbcondecor device. These ioctls are to be used by both the userspace helper
140 +(called only by the kernel) and userspace configuration tools (run by the users).
141 +
142 +The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL
143 +when doing the appropriate ioctls. All userspace configuration tools should
144 +use FBCON_DECOR_IO_ORIG_USER. Failure to set the appropriate value in the origin
145 +field when performing ioctls from the kernel helper will most likely result
146 +in a console deadlock.
147 +
148 +FBCON_DECOR_IO_ORIG_KERNEL instructs fbcondecor not to try to acquire the console
149 +semaphore. Not surprisingly, FBCON_DECOR_IO_ORIG_USER instructs it to acquire
150 +the console sem.
151 +
152 +The framebuffer console decoration provides the following ioctls (all defined in
153 +linux/fb.h):
154 +
155 +FBIOCONDECOR_SETPIC
156 +description: loads a background picture for a virtual console
157 +argument: struct fbcon_decor_iowrapper*; data: struct fb_image*
158 +notes:
159 +If called for consoles other than the current foreground one, the picture data
160 +will be ignored.
161 +
162 +If the current virtual console is running in a 8-bpp mode, the cmap substruct
163 +of fb_image has to be filled appropriately: start should be set to 16 (first
164 +16 colors are reserved for fbcon), len to a value <= 240 and red, green and
165 +blue should point to valid cmap data. The transp field is ingored. The fields
166 +dx, dy, bg_color, fg_color in fb_image are ignored as well.
167 +
168 +FBIOCONDECOR_SETCFG
169 +description: sets the fbcondecor config for a virtual console
170 +argument: struct fbcon_decor_iowrapper*; data: struct vc_decor*
171 +notes: The structure has to be filled with valid data.
172 +
173 +FBIOCONDECOR_GETCFG
174 +description: gets the fbcondecor config for a virtual console
175 +argument: struct fbcon_decor_iowrapper*; data: struct vc_decor*
176 +
177 +FBIOCONDECOR_SETSTATE
178 +description: sets the fbcondecor state for a virtual console
179 +argument: struct fbcon_decor_iowrapper*; data: unsigned int*
180 + values: 0 = disabled, 1 = enabled.
181 +
182 +FBIOCONDECOR_GETSTATE
183 +description: gets the fbcondecor state for a virtual console
184 +argument: struct fbcon_decor_iowrapper*; data: unsigned int*
185 + values: as in FBIOCONDECOR_SETSTATE
186 +
187 +Info on used structures:
188 +
189 +Definition of struct vc_decor can be found in linux/console_decor.h. It's
190 +heavily commented. Note that the 'theme' field should point to a string
191 +no longer than FBCON_DECOR_THEME_LEN. When FBIOCONDECOR_GETCFG call is
192 +performed, the theme field should point to a char buffer of length
193 +FBCON_DECOR_THEME_LEN.
194 +
195 +Definition of struct fbcon_decor_iowrapper can be found in linux/fb.h.
196 +The fields in this struct have the following meaning:
197 +
198 +vc:
199 +Virtual console number.
200 +
201 +origin:
202 +Specifies if the ioctl is performed as a response to a kernel request. The
203 +fbcondecor helper should set this field to FBCON_DECOR_IO_ORIG_KERNEL, userspace
204 +programs should set it to FBCON_DECOR_IO_ORIG_USER. This field is necessary to
205 +avoid console semaphore deadlocks.
206 +
207 +data:
208 +Pointer to a data structure appropriate for the performed ioctl. Type of
209 +the data struct is specified in the ioctls description.
