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.
