20 | +What is it? | ||
21 | +----------- | ||
22 | + | ||
23 | +The framebuffer decorations are a kernel feature which allows displaying a | ||
24 | +background picture on selected consoles. | ||
25 | + | ||
26 | +What do I need to get it to work? | ||
27 | +--------------------------------- | ||
28 | + | ||
29 | +To get fbcondecor up-and-running you will have to: | ||
30 | + 1) get a copy of splashutils [1] or a similar program | ||
31 | + 2) get some fbcondecor themes | ||
32 | + 3) build the kernel helper program | ||
33 | + 4) build your kernel with the FB_CON_DECOR option enabled. | ||
34 | + | ||
35 | +To get fbcondecor 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 fbcondecor helper (by default: /sbin/fbcondecor_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 fbcondecor helper must be accessible at | ||
50 | +all times. If it's not, fbcondecor will be switched off automatically. | ||
51 | + | ||
52 | +It's possible to set path to the fbcondecor helper by writing it to | ||
53 | +/proc/sys/kernel/fbcondecor. | ||
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 fbcondecor protocol | ||
61 | +----------------------- | ||
62 | + | ||
63 | +The fbcondecor protocol defines a communication interface between the kernel and | ||
64 | +the userspace fbcondecor 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 fbcondecor 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 fbcondecor 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 | +<fbcondecor protocol version> <command> <parameters> | ||
89 | + | ||
90 | +All commands defined in fbcondecor protocol v2 have the following parameters: | ||
91 | + virtual console | ||
92 | + framebuffer number | ||
93 | + theme | ||
94 | + | ||
95 | +Fbcondecor protocol v1 specified an additional 'fbcondecor mode' after the | ||
96 | +framebuffer number. Fbcondecor protocol v1 is deprecated and should not be used. | ||
97 | + | ||
98 | +Fbcondecor 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 FBIOCONDECOR_SETPIC ioctl. | ||
106 | + | ||
107 | +init | ||
108 | +---- | ||
109 | + The kernel issues this command after the fbcondecor device is created and | ||
110 | + the fbcondecor interface is initialized. Upon receiving 'init', the userspace | ||
111 | + helper should parse the kernel command line (/proc/cmdline) or otherwise | ||
112 | + decide whether fbcondecor is to be activated. | ||
113 | + | ||
114 | + To activate fbcondecor on the first console the helper should issue the | ||
115 | + FBIOCONDECOR_SETCFG, FBIOCONDECOR_SETPIC and FBIOCONDECOR_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, fbcondecor 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 fbcondecor_helper | ||
127 | + with the 'init' command. The fbcondecor helper should perform all ioctls with | ||
128 | + origin set to FBCON_DECOR_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 | + FBCON_DECOR_IO_ORIG_KERNEL. | ||
136 | + | ||
137 | + | ||
138 | +Userspace -> Kernel | ||
139 | +------------------- | ||
140 | + | ||
141 | +Userspace programs can communicate with fbcondecor via ioctls on the | ||
142 | +fbcondecor device. These ioctls are to be used by both the userspace helper | ||
143 | +(called only by the kernel) and userspace configuration tools (run by the users). | ||
144 | + | ||
145 | +The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL | ||
146 | +when doing the appropriate ioctls. All userspace configuration tools should | ||
147 | +use FBCON_DECOR_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 | +FBCON_DECOR_IO_ORIG_KERNEL instructs fbcondecor not to try to acquire the console | ||
152 | +semaphore. Not surprisingly, FBCON_DECOR_IO_ORIG_USER instructs it to acquire | ||
153 | +the console sem. | ||
154 | + | ||
155 | +The framebuffer console decoration provides the following ioctls (all defined in | ||
156 | +linux/fb.h): | ||
157 | + | ||
158 | +FBIOCONDECOR_SETPIC | ||
159 | +description: loads a background picture for a virtual console | ||
160 | +argument: struct fbcon_decor_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 | +FBIOCONDECOR_SETCFG | ||
172 | +description: sets the fbcondecor config for a virtual console | ||
173 | +argument: struct fbcon_decor_iowrapper*; data: struct vc_decor* | ||
174 | +notes: The structure has to be filled with valid data. | ||
175 | + | ||
176 | +FBIOCONDECOR_GETCFG | ||
177 | +description: gets the fbcondecor config for a virtual console | ||
178 | +argument: struct fbcon_decor_iowrapper*; data: struct vc_decor* | ||
179 | + | ||
180 | +FBIOCONDECOR_SETSTATE | ||
181 | +description: sets the fbcondecor state for a virtual console | ||
182 | +argument: struct fbcon_decor_iowrapper*; data: unsigned int* | ||
183 | + values: 0 = disabled, 1 = enabled. | ||
184 | + | ||
185 | +FBIOCONDECOR_GETSTATE | ||
186 | +description: gets the fbcondecor state for a virtual console | ||
187 | +argument: struct fbcon_decor_iowrapper*; data: unsigned int* | ||
188 | + values: as in FBIOCONDECOR_SETSTATE | ||
189 | + | ||
190 | +Info on used structures: | ||
191 | + | ||
192 | +Definition of struct vc_decor can be found in linux/console_decor.h. It's | ||
193 | +heavily commented. Note that the 'theme' field should point to a string | ||
194 | +no longer than FBCON_DECOR_THEME_LEN. When FBIOCONDECOR_GETCFG call is | ||
195 | +performed, the theme field should point to a char buffer of length | ||
196 | +FBCON_DECOR_THEME_LEN. | ||
197 | + | ||
198 | +Definition of struct fbcon_decor_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 | +fbcondecor helper should set this field to FBCON_DECOR_IO_ORIG_KERNEL, userspace | ||
207 | +programs should set it to FBCON_DECOR_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. | ||
