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.
