WSKBD (9) NetBSD Kernel Developer’s Manual WSKBD (9)pos [cmd] normal shift altgr shift-altgrFUNCTIONSwskbd_input(kbddev , type , value)Pass the keypress of value value and type type to wscons keyboard driver. Valid values oftype are:WSCONS_EVENT_KEY_UPKey released.WSCONS_EVENT_KEY_DOWNKey pressed.wskbd_rawinput(kbddev , buf , len)Pass the raw keypress in the buffer buf to the wscons keyboard driver. The buffer is len byteslong. This function should only be called if the kernel option WSDISPLAY_COMPAT_RAWKBDis enabled.wskbd_cnattach(consops , conscookie , mapdata)Attach this keyboard as the console input by specifying the console operations consops and thekeyboard mapping table information in mapdata. The functions specified in consops will becalled with conscookie as the first argument.wskbd_cndetach()Detach this keyboard as the console input.wskbddevprint(aux , pnp)The default wskbd printing routine used by config_found(). (see autoconf(9)).AUTOCONFIGURATIONKeyboard drivers which want to use the wskbd module must be a parent to the wskbd(4) device and providean attachment interface. To attach the wskbd(4) device, the keyboard driver must allocate and populate awskbddev_attach_args structure with the supported operations and callbacks and callconfig_found() to perform the attach (see autoconf(9)). The keymap member points to thewskbd_mapdata structure which describes the keycode mapping operations. The accessops memberpoints to the wskbd_accessops structure which describes the keyboard access operations. The consolemember is a boolean to indicate to wscons whether this keyboard will be used for console input.OPERATIONIf the keyboard belongs to the system console, it must register the wskbd_consops structure specifyingthe console operations via wskbd_cnattach() at console attach time.When a keypress arrives from the keyboard, the keyboard driver must perform any necessary characterdecoding to wscons events and pass the events to wscons via wskbd_input(). If the kernel is compiledwith the option WSDISPLAY_COMPAT_RAWKBD, then the keyboard driver must also pass the raw keyboarddata to wscons via wskbd_rawinput().The wscons framework calls back into the hardware driver byinv oking the functions that are specified in theaccessops structure. The enable() and set_leds() functions are relatively simple and self-explanatory.The ioctl() function is called by the wscons interface to perform keyboard-specific ioctl operations (seeioctl(2)). The argument cmd to the ioctl() function specifies the specific command to perform usingthe data data. Valid commands are listed in sys/dev/wscons/wsconsio.h.NetBSD 3.0 December 20, 2005 3
WSKBD (9) NetBSD Kernel Developer’s Manual WSKBD (9)CODE REFERENCESThis section describes places within the NetBSD source tree where actual code implementing or using themachine-independent wscons subsystem can be found. All pathnames are relative to /usr/src.The wscons subsystem is implemented within the directory sys/dev/wscons. The wskbd module itselfis implement within the files sys/dev/wscons/wskbd.c and sys/dev/wscons/wskbdutil.c.ioctl(2) operations are listed in sys/dev/wscons/wsconsio.h.SEE ALSOioctl(2), autoconf(9), driver(9), intro(9), wsdisplay(9), wsmouse(9)NetBSD 3.0 December 20, 2005 4
