Important events include console switches and video ++mode switches (the kernel requests background images and configuration ++parameters for the current console). The fbcondecor helper must be accessible at ++all times. If it's not, fbcondecor will be switched off automatically. ++ ++It's possible to set path to the fbcondecor helper by writing it to ++/proc/sys/kernel/fbcondecor. ++ ++***************************************************************************** ++ ++The information below is mostly technical stuff. There's probably no need to ++read it unless you plan to develop a userspace helper. ++ ++The fbcondecor protocol ++----------------------- ++ ++The fbcondecor protocol defines a communication interface between the kernel and ++the userspace fbcondecor helper. ++ ++The kernel side is responsible for: ++ ++ * rendering console text, using an image as a background (instead of a ++ standard solid color fbcon uses), ++ * accepting commands from the user via ioctls on the fbcondecor device, ++ * calling the userspace helper to set things up as soon as the fb subsystem ++ is initialized. ++ ++The userspace helper is responsible for everything else, including parsing ++configuration files, decompressing the image files whenever the kernel needs ++it, and communicating with the kernel if necessary. ++ ++The fbcondecor protocol specifies how communication is done in both ways: ++kernel->userspace and userspace->helper. ++ ++Kernel -> Userspace ++------------------- ++ ++The kernel communicates with the userspace helper by calling it and specifying ++the task to be done in a series of arguments. ++ ++The arguments follow the pattern: ++<fbcondecor protocol version> <command> <parameters> ++ ++All commands defined in fbcondecor protocol v2 have the following parameters: ++ virtual console ++ framebuffer number ++ theme ++ ++Fbcondecor protocol v1 specified an additional 'fbcondecor mode' after the ++framebuffer number. Fbcondecor protocol v1 is deprecated and should not be used. ++ ++Fbcondecor protocol v2 specifies the following commands: ++ ++getpic ++------ ++ The kernel issues this command to request image data. It's up to the ++ userspace helper to find a background image appropriate for the specified ++ theme and the current resolution. The userspace helper should respond by ++ issuing the FBIOCONDECOR_SETPIC ioctl. ++ ++init ++---- ++ The kernel issues this command after the fbcondecor device is created and ++ the fbcondecor interface is initialized. Upon receiving 'init', the userspace ++ helper should parse the kernel command line (/proc/cmdline) or otherwise ++ decide whether fbcondecor is to be activated. ++ ++ To activate fbcondecor on the first console the helper should issue the ++ FBIOCONDECOR_SETCFG, FBIOCONDECOR_SETPIC and FBIOCONDECOR_SETSTATE commands, ++ in the above-mentioned order. ++ ++ When the userspace helper is called in an early phase of the boot process ++ (right after the initialization of fbcon), no filesystems will be mounted. ++ The helper program should mount sysfs and then create the appropriate ++ framebuffer, fbcondecor and tty0 devices (if they don't already exist) to get ++ current display settings and to be able to communicate with the kernel side. ++ It should probably also mount the procfs to be able to parse the kernel ++ command line parameters. ++ ++ Note that the console sem is not held when the kernel calls fbcondecor_helper ++ with the 'init' command. The fbcondecor helper should perform all ioctls with ++ origin set to FBCON_DECOR_IO_ORIG_USER. ++ ++modechange ++---------- ++ The kernel issues this command on a mode change. The helper's response should ++ be similar to the response to the 'init' command. Note that this time the ++ console sem is held and all ioctls must be performed with origin set to ++ FBCON_DECOR_IO_ORIG_KERNEL. ++ ++ ++Userspace -> Kernel ++------------------- ++ ++Userspace programs can communicate with fbcondecor via ioctls on the ++fbcondecor device. These ioctls are to be used by both the userspace helper ++(called only by the kernel) and userspace configuration tools (run by the users). ++ ++The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL ++when doing the appropriate ioctls. All userspace configuration tools should ++use FBCON_DECOR_IO_ORIG_USER. Failure to set the appropriate value in the origin ++field when performing ioctls from the kernel helper will most likely result ++in a console deadlock. ++ ++FBCON_DECOR_IO_ORIG_KERNEL instructs fbcondecor not to try to acquire the console ++semaphore. Not surprisingly, FBCON_DECOR_IO_ORIG_USER instructs it to acquire ++the console sem. ++ ++The framebuffer console decoration provides the following ioctls (all defined in ++linux/fb.h): ++ ++FBIOCONDECOR_SETPIC ++description: loads a background picture for a virtual console ++argument: struct fbcon_decor_iowrapper*; data: struct fb_image* ++notes: ++If called for consoles other than the current foreground one, the picture data ++will be ignored. ++ ++If the current virtual console is running in a 8-bpp mode, the cmap substruct ++of fb_image has to be filled appropriately: start should be set to 16 (first ++16 colors are reserved for fbcon), len to a value <= 240 and red, green and ++blue should point to valid cmap data. The transp field is ingored. The fields ++dx, dy, bg_color, fg_color in fb_image are ignored as well. ++ ++FBIOCONDECOR_SETCFG ++description: sets the fbcondecor config for a virtual console ++argument: struct fbcon_decor_iowrapper*; data: struct vc_decor* ++notes: The structure has to be filled with valid data. ++ ++FBIOCONDECOR_GETCFG ++description: gets the fbcondecor config for a virtual console ++argument: struct fbcon_decor_iowrapper*; data: struct vc_decor* ++ ++FBIOCONDECOR_SETSTATE ++description: sets the fbcondecor state for a virtual console ++argument: struct fbcon_decor_iowrapper*; data: unsigned int* ++ values: 0 = disabled, 1 = enabled. ++ ++FBIOCONDECOR_GETSTATE ++description: gets the fbcondecor state for a virtual console ++argument: struct fbcon_decor_iowrapper*; data: unsigned int* ++ values: as in FBIOCONDECOR_SETSTATE ++ ++Info on used structures: ++ ++Definition of struct vc_decor can be found in linux/console_decor.h. It's ++heavily commented. Note that the 'theme' field should point to a string ++no longer than FBCON_DECOR_THEME_LEN. When FBIOCONDECOR_GETCFG call is ++performed, the theme field should point to a char buffer of length ++FBCON_DECOR_THEME_LEN. ++ ++Definition of struct fbcon_decor_iowrapper can be found in linux/fb.h. ++The fields in this struct have the following meaning: ++ ++vc: ++Virtual console number. ++ ++origin: ++Specifies if the ioctl is performed as a response to a kernel request. The ++fbcondecor helper should set this field to FBCON_DECOR_IO_ORIG_KERNEL, userspace ++programs should set it to FBCON_DECOR_IO_ORIG_USER. This field is necessary to ++avoid console semaphore deadlocks. ++ ++data: ++Pointer to a data structure appropriate for the performed ioctl.
