39 -+What is it?
40 -+-----------
41 -+
42 -+The framebuffer decorations are a kernel feature which allows displaying a
43 -+background picture on selected consoles.
44 -+
45 -+What do I need to get it to work?
46 -+---------------------------------
47 -+
48 -+To get fbcondecor up-and-running you will have to:
49 -+ 1) get a copy of splashutils [1] or a similar program
50 -+ 2) get some fbcondecor themes
51 -+ 3) build the kernel helper program
52 -+ 4) build your kernel with the FB_CON_DECOR option enabled.
53 -+
54 -+To get fbcondecor operational right after fbcon initialization is finished, you
55 -+will have to include a theme and the kernel helper into your initramfs image.
56 -+Please refer to splashutils documentation for instructions on how to do that.
57 -+
58 -+[1] The splashutils package can be downloaded from:
59 -+ http://github.com/alanhaggai/fbsplash
60 -+
61 -+The userspace helper
62 -+--------------------
63 -+
64 -+The userspace fbcondecor helper (by default: /sbin/fbcondecor_helper) is called by the
65 -+kernel whenever an important event occurs and the kernel needs some kind of
66 -+job to be carried out. Important events include console switches and video
67 -+mode switches (the kernel requests background images and configuration
68 -+parameters for the current console). The fbcondecor helper must be accessible at
69 -+all times. If it's not, fbcondecor will be switched off automatically.
70 -+
71 -+It's possible to set path to the fbcondecor helper by writing it to
72 -+/proc/sys/kernel/fbcondecor.
73 -+
74 -+*****************************************************************************
75 -+
76 -+The information below is mostly technical stuff. There's probably no need to
77 -+read it unless you plan to develop a userspace helper.
78 -+
79 -+The fbcondecor protocol
80 -+-----------------------
81 -+
82 -+The fbcondecor protocol defines a communication interface between the kernel and
83 -+the userspace fbcondecor helper.
84 -+
85 -+The kernel side is responsible for:
86 -+
87 -+ * rendering console text, using an image as a background (instead of a
88 -+ standard solid color fbcon uses),
89 -+ * accepting commands from the user via ioctls on the fbcondecor device,
90 -+ * calling the userspace helper to set things up as soon as the fb subsystem
91 -+ is initialized.
92 -+
93 -+The userspace helper is responsible for everything else, including parsing
94 -+configuration files, decompressing the image files whenever the kernel needs
95 -+it, and communicating with the kernel if necessary.
96 -+
97 -+The fbcondecor protocol specifies how communication is done in both ways:
98 -+kernel->userspace and userspace->helper.
99 -+
100 -+Kernel -> Userspace
101 -+-------------------
102 -+
103 -+The kernel communicates with the userspace helper by calling it and specifying
104 -+the task to be done in a series of arguments.
105 -+
106 -+The arguments follow the pattern:
107 -+<fbcondecor protocol version> <command> <parameters>
108 -+
109 -+All commands defined in fbcondecor protocol v2 have the following parameters:
110 -+ virtual console
111 -+ framebuffer number
112 -+ theme
113 -+
114 -+Fbcondecor protocol v1 specified an additional 'fbcondecor mode' after the
115 -+framebuffer number. Fbcondecor protocol v1 is deprecated and should not be used.
116 -+
117 -+Fbcondecor protocol v2 specifies the following commands:
118 -+
119 -+getpic
120 -+------
121 -+ The kernel issues this command to request image data. It's up to the
122 -+ userspace helper to find a background image appropriate for the specified
123 -+ theme and the current resolution. The userspace helper should respond by
124 -+ issuing the FBIOCONDECOR_SETPIC ioctl.
125 -+
126 -+init
127 -+----
128 -+ The kernel issues this command after the fbcondecor device is created and
129 -+ the fbcondecor interface is initialized. Upon receiving 'init', the userspace
130 -+ helper should parse the kernel command line (/proc/cmdline) or otherwise
131 -+ decide whether fbcondecor is to be activated.
132 -+
133 -+ To activate fbcondecor on the first console the helper should issue the
134 -+ FBIOCONDECOR_SETCFG, FBIOCONDECOR_SETPIC and FBIOCONDECOR_SETSTATE commands,
135 -+ in the above-mentioned order.
136 -+
137 -+ When the userspace helper is called in an early phase of the boot process
138 -+ (right after the initialization of fbcon), no filesystems will be mounted.
139 -+ The helper program should mount sysfs and then create the appropriate
140 -+ framebuffer, fbcondecor and tty0 devices (if they don't already exist) to get
141 -+ current display settings and to be able to communicate with the kernel side.
142 -+ It should probably also mount the procfs to be able to parse the kernel
143 -+ command line parameters.
144 -+
145 -+ Note that the console sem is not held when the kernel calls fbcondecor_helper
146 -+ with the 'init' command. The fbcondecor helper should perform all ioctls with
147 -+ origin set to FBCON_DECOR_IO_ORIG_USER.
148 -+
149 -+modechange
150 -+----------
151 -+ The kernel issues this command on a mode change. The helper's response should
152 -+ be similar to the response to the 'init' command. Note that this time the
153 -+ console sem is held and all ioctls must be performed with origin set to
154 -+ FBCON_DECOR_IO_ORIG_KERNEL.
155 -+
156 -+
157 -+Userspace -> Kernel
158 -+-------------------
159 -+
160 -+Userspace programs can communicate with fbcondecor via ioctls on the
161 -+fbcondecor device. These ioctls are to be used by both the userspace helper
162 -+(called only by the kernel) and userspace configuration tools (run by the users).
163 -+
164 -+The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL
165 -+when doing the appropriate ioctls. All userspace configuration tools should
166 -+use FBCON_DECOR_IO_ORIG_USER. Failure to set the appropriate value in the origin
167 -+field when performing ioctls from the kernel helper will most likely result
168 -+in a console deadlock.
169 -+
170 -+FBCON_DECOR_IO_ORIG_KERNEL instructs fbcondecor not to try to acquire the console
171 -+semaphore. Not surprisingly, FBCON_DECOR_IO_ORIG_USER instructs it to acquire
172 -+the console sem.
173 -+
174 -+The framebuffer console decoration provides the following ioctls (all defined in
175 -+linux/fb.h):
176 -+
177 -+FBIOCONDECOR_SETPIC
178 -+description: loads a background picture for a virtual console
179 -+argument: struct fbcon_decor_iowrapper*; data: struct fb_image*
180 -+notes:
181 -+If called for consoles other than the current foreground one, the picture data
182 -+will be ignored.
183 -+
184 -+If the current virtual console is running in a 8-bpp mode, the cmap substruct
185 -+of fb_image has to be filled appropriately: start should be set to 16 (first
186 -+16 colors are reserved for fbcon), len to a value <= 240 and red, green and
187 -+blue should point to valid cmap data. The transp field is ingored. The fields
188 -+dx, dy, bg_color, fg_color in fb_image are ignored as well.
189 -+
190 -+FBIOCONDECOR_SETCFG
191 -+description: sets the fbcondecor config for a virtual console
192 -+argument: struct fbcon_decor_iowrapper*; data: struct vc_decor*
193 -+notes: The structure has to be filled with valid data.
194 -+
195 -+FBIOCONDECOR_GETCFG
196 -+description: gets the fbcondecor config for a virtual console
197 -+argument: struct fbcon_decor_iowrapper*; data: struct vc_decor*
198 -+
199 -+FBIOCONDECOR_SETSTATE
200 -+description: sets the fbcondecor state for a virtual console
201 -+argument: struct fbcon_decor_iowrapper*; data: unsigned int*
202 -+ values: 0 = disabled, 1 = enabled.
203 -+
204 -+FBIOCONDECOR_GETSTATE
205 -+description: gets the fbcondecor state for a virtual console
206 -+argument: struct fbcon_decor_iowrapper*; data: unsigned int*
207 -+ values: as in FBIOCONDECOR_SETSTATE
208 -+
209 -+Info on used structures:
210 -+
211 -+Definition of struct vc_decor can be found in linux/console_decor.h. It's
212 -+heavily commented. Note that the 'theme' field should point to a string
213 -+no longer than FBCON_DECOR_THEME_LEN. When FBIOCONDECOR_GETCFG call is
214 -+performed, the theme field should point to a char buffer of length
215 -+FBCON_DECOR_THEME_LEN.
216 -+
217 -+Definition of struct fbcon_decor_iowrapper can be found in linux/fb.h.
218 -+The fields in this struct have the following meaning:
219 -+
220 -+vc:
221 -+Virtual console number.
222 -+
223 -+origin:
224 -+Specifies if the ioctl is performed as a response to a kernel request. The
225 -+fbcondecor helper should set this field to FBCON_DECOR_IO_ORIG_KERNEL, userspace
226 -+programs should set it to FBCON_DECOR_IO_ORIG_USER. This field is necessary to
227 -+avoid console semaphore deadlocks.
228 -+
229 -+data:
230 -+Pointer to a data structure appropriate for the performed ioctl. Type of
231 -+the data struct is specified in the ioctls description.
