  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://github.com/alanhaggai/fbsplash

  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.
