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. |
