++What is it? |
56 |
++----------- |
57 |
++ |
58 |
++The framebuffer decorations are a kernel feature which allows displaying a |
59 |
++background picture on selected consoles. |
60 |
++ |
61 |
++What do I need to get it to work? |
62 |
++--------------------------------- |
63 |
++ |
64 |
++To get fbcondecor up-and-running you will have to: |
65 |
++ 1) get a copy of splashutils [1] or a similar program |
66 |
++ 2) get some fbcondecor themes |
67 |
++ 3) build the kernel helper program |
68 |
++ 4) build your kernel with the FB_CON_DECOR option enabled. |
69 |
++ |
70 |
++To get fbcondecor operational right after fbcon initialization is finished, you |
71 |
++will have to include a theme and the kernel helper into your initramfs image. |
72 |
++Please refer to splashutils documentation for instructions on how to do that. |
73 |
++ |
74 |
++[1] The splashutils package can be downloaded from: |
75 |
++ http://github.com/alanhaggai/fbsplash |
76 |
++ |
77 |
++The userspace helper |
78 |
++-------------------- |
79 |
++ |
80 |
++The userspace fbcondecor helper (by default: /sbin/fbcondecor_helper) is called by the |
81 |
++kernel whenever an important event occurs and the kernel needs some kind of |
82 |
++job to be carried out. Important events include console switches and video |
83 |
++mode switches (the kernel requests background images and configuration |
84 |
++parameters for the current console). The fbcondecor helper must be accessible at |
85 |
++all times. If it's not, fbcondecor will be switched off automatically. |
86 |
++ |
87 |
++It's possible to set path to the fbcondecor helper by writing it to |
88 |
++/proc/sys/kernel/fbcondecor. |
89 |
++ |
90 |
++***************************************************************************** |
91 |
++ |
92 |
++The information below is mostly technical stuff. There's probably no need to |
93 |
++read it unless you plan to develop a userspace helper. |
94 |
++ |
95 |
++The fbcondecor protocol |
96 |
++----------------------- |
97 |
++ |
98 |
++The fbcondecor protocol defines a communication interface between the kernel and |
99 |
++the userspace fbcondecor helper. |
100 |
++ |
101 |
++The kernel side is responsible for: |
102 |
++ |
103 |
++ * rendering console text, using an image as a background (instead of a |
104 |
++ standard solid color fbcon uses), |
105 |
++ * accepting commands from the user via ioctls on the fbcondecor device, |
106 |
++ * calling the userspace helper to set things up as soon as the fb subsystem |
107 |
++ is initialized. |
108 |
++ |
109 |
++The userspace helper is responsible for everything else, including parsing |
110 |
++configuration files, decompressing the image files whenever the kernel needs |
111 |
++it, and communicating with the kernel if necessary. |
112 |
++ |
113 |
++The fbcondecor protocol specifies how communication is done in both ways: |
114 |
++kernel->userspace and userspace->helper. |
115 |
++ |
116 |
++Kernel -> Userspace |
117 |
++------------------- |
118 |
++ |
119 |
++The kernel communicates with the userspace helper by calling it and specifying |
120 |
++the task to be done in a series of arguments. |
121 |
++ |
122 |
++The arguments follow the pattern: |
123 |
++<fbcondecor protocol version> <command> <parameters> |
124 |
++ |
125 |
++All commands defined in fbcondecor protocol v2 have the following parameters: |
126 |
++ virtual console |
127 |
++ framebuffer number |
128 |
++ theme |
129 |
++ |
130 |
++Fbcondecor protocol v1 specified an additional 'fbcondecor mode' after the |
131 |
++framebuffer number. Fbcondecor protocol v1 is deprecated and should not be used. |
132 |
++ |
133 |
++Fbcondecor protocol v2 specifies the following commands: |
134 |
++ |
135 |
++getpic |
136 |
++------ |
137 |
++ The kernel issues this command to request image data. It's up to the |
138 |
++ userspace helper to find a background image appropriate for the specified |
139 |
++ theme and the current resolution. The userspace helper should respond by |
140 |
++ issuing the FBIOCONDECOR_SETPIC ioctl. |
141 |
++ |
142 |
++init |
143 |
++---- |
144 |
++ The kernel issues this command after the fbcondecor device is created and |
145 |
++ the fbcondecor interface is initialized. Upon receiving 'init', the userspace |
146 |
++ helper should parse the kernel command line (/proc/cmdline) or otherwise |
147 |
++ decide whether fbcondecor is to be activated. |
148 |
++ |
149 |
++ To activate fbcondecor on the first console the helper should issue the |
150 |
++ FBIOCONDECOR_SETCFG, FBIOCONDECOR_SETPIC and FBIOCONDECOR_SETSTATE commands, |
151 |
++ in the above-mentioned order. |
152 |
++ |
153 |
++ When the userspace helper is called in an early phase of the boot process |
154 |
++ (right after the initialization of fbcon), no filesystems will be mounted. |
155 |
++ The helper program should mount sysfs and then create the appropriate |
156 |
++ framebuffer, fbcondecor and tty0 devices (if they don't already exist) to get |
157 |
++ current display settings and to be able to communicate with the kernel side. |
158 |
++ It should probably also mount the procfs to be able to parse the kernel |
159 |
++ command line parameters. |
160 |
++ |
161 |
++ Note that the console sem is not held when the kernel calls fbcondecor_helper |
162 |
++ with the 'init' command. The fbcondecor helper should perform all ioctls with |
163 |
++ origin set to FBCON_DECOR_IO_ORIG_USER. |
164 |
++ |
165 |
++modechange |
166 |
++---------- |
167 |
++ The kernel issues this command on a mode change. The helper's response should |
168 |
++ be similar to the response to the 'init' command. Note that this time the |
169 |
++ console sem is held and all ioctls must be performed with origin set to |
170 |
++ FBCON_DECOR_IO_ORIG_KERNEL. |
171 |
++ |
172 |
++ |
173 |
++Userspace -> Kernel |
174 |
++------------------- |
175 |
++ |
176 |
++Userspace programs can communicate with fbcondecor via ioctls on the |
177 |
++fbcondecor device. These ioctls are to be used by both the userspace helper |
178 |
++(called only by the kernel) and userspace configuration tools (run by the users). |
179 |
++ |
180 |
++The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL |
181 |
++when doing the appropriate ioctls. All userspace configuration tools should |
182 |
++use FBCON_DECOR_IO_ORIG_USER. Failure to set the appropriate value in the origin |
183 |
++field when performing ioctls from the kernel helper will most likely result |
184 |
++in a console deadlock. |
185 |
++ |
186 |
++FBCON_DECOR_IO_ORIG_KERNEL instructs fbcondecor not to try to acquire the console |
187 |
++semaphore. Not surprisingly, FBCON_DECOR_IO_ORIG_USER instructs it to acquire |
188 |
++the console sem. |
189 |
++ |
190 |
++The framebuffer console decoration provides the following ioctls (all defined in |
191 |
++linux/fb.h): |
192 |
++ |
193 |
++FBIOCONDECOR_SETPIC |
194 |
++description: loads a background picture for a virtual console |
195 |
++argument: struct fbcon_decor_iowrapper*; data: struct fb_image* |
196 |
++notes: |
197 |
++If called for consoles other than the current foreground one, the picture data |
198 |
++will be ignored. |
199 |
++ |
200 |
++If the current virtual console is running in a 8-bpp mode, the cmap substruct |
201 |
++of fb_image has to be filled appropriately: start should be set to 16 (first |
202 |
++16 colors are reserved for fbcon), len to a value <= 240 and red, green and |
203 |
++blue should point to valid cmap data. The transp field is ingored. The fields |
204 |
++dx, dy, bg_color, fg_color in fb_image are ignored as well. |
205 |
++ |
206 |
++FBIOCONDECOR_SETCFG |
207 |
++description: sets the fbcondecor config for a virtual console |
208 |
++argument: struct fbcon_decor_iowrapper*; data: struct vc_decor* |
209 |
++notes: The structure has to be filled with valid data. |
210 |
++ |
211 |
++FBIOCONDECOR_GETCFG |
212 |
++description: gets the fbcondecor config for a virtual console |
213 |
++argument: struct fbcon_decor_iowrapper*; data: struct vc_decor* |
214 |
++ |
215 |
++FBIOCONDECOR_SETSTATE |
216 |
++description: sets the fbcondecor state for a virtual console |
217 |
++argument: struct fbcon_decor_iowrapper*; data: unsigned int* |
218 |
++ values: 0 = disabled, 1 = enabled. |
219 |
++ |
220 |
++FBIOCONDECOR_GETSTATE |
221 |
++description: gets the fbcondecor state for a virtual console |
222 |
++argument: struct fbcon_decor_iowrapper*; data: unsigned int* |
223 |
++ values: as in FBIOCONDECOR_SETSTATE |
224 |
++ |
225 |
++Info on used structures: |
226 |
++ |
227 |
++Definition of struct vc_decor can be found in linux/console_decor.h. It's |
228 |
++heavily commented. Note that the 'theme' field should point to a string |
229 |
++no longer than FBCON_DECOR_THEME_LEN. When FBIOCONDECOR_GETCFG call is |
230 |
++performed, the theme field should point to a char buffer of length |
231 |
++FBCON_DECOR_THEME_LEN. |
232 |
++ |
233 |
++Definition of struct fbcon_decor_iowrapper can be found in linux/fb.h. |
234 |
++The fields in this struct have the following meaning: |
235 |
++ |
236 |
++vc: |
237 |
++Virtual console number. |
238 |
++ |
239 |
++origin: |
240 |
++Specifies if the ioctl is performed as a response to a kernel request. The |
241 |
++fbcondecor helper should set this field to FBCON_DECOR_IO_ORIG_KERNEL, userspace |
242 |
++programs should set it to FBCON_DECOR_IO_ORIG_USER. This field is necessary to |
243 |
++avoid console semaphore deadlocks. |
244 |
++ |
245 |
++data: |
246 |
++Pointer to a data structure appropriate for the performed ioctl. Type of |
247 |
++the data struct is specified in the ioctls description. |
