6 tristate "Serial I/O support"
9 Say Yes here if you have any input device that uses serial I/O to
10 communicate with the system. This includes the
11 * standard AT keyboard and PS/2 mouse *
12 as well as serial mice, Sun keyboards, some joysticks and 6dof
17 To compile this driver as a module, choose M here: the
18 module will be called serio.
20 config ARCH_MIGHT_HAVE_PC_SERIO
23 Select this config option from the architecture Kconfig if
24 the architecture might use a PC serio device (i8042) to
25 communicate with keyboard, mouse, etc.
30 tristate "i8042 PC Keyboard controller"
32 depends on ARCH_MIGHT_HAVE_PC_SERIO
34 i8042 is the chip over which the standard AT keyboard and PS/2
35 mouse are connected to the computer. If you use these devices,
36 you'll need to say Y here.
40 To compile this driver as a module, choose M here: the
41 module will be called i8042.
44 tristate "Serial port line discipline"
48 Say Y here if you plan to use an input device (mouse, joystick,
49 tablet, 6dof) that communicates over the RS232 serial (COM) port.

114 over which HP PS/2 keyboards and PS/2 mice may be connected.
115 If you use these devices, you'll need to say Y here.
117 It's safe to enable this driver, so if unsure, say Y.
119 To compile this driver as a module, choose M here: the
120 module will be called gscps2.
123 tristate "HP System Device Controller i8042 Support"
124 depends on (GSC || HP300) && SERIO
127 This option enables support for the "System Device
128 Controller", an i8042 carrying microcode to manage a
129 few miscellaneous devices on some Hewlett Packard systems.
130 The SDC itself contains a 10ms resolution timer/clock capable
131 of delivering interrupts on a periodic and one-shot basis.
132 The SDC may also be connected to a battery-backed real-time
133 clock, a basic audio waveform generator, and an HP-HIL Master
134 Link Controller serving up to seven input devices.
136 By itself this option is rather useless, but enabling it will
137 enable selection of drivers for the abovementioned devices.
138 It is, however, incompatible with the old, reliable HIL keyboard
139 driver, and the new HIL driver is experimental, so if you plan
140 to use a HIL keyboard as your primary keyboard, you may wish
141 to keep using that driver until the new HIL drivers have had
145 tristate "HIL MLC Support (needed for HIL input devices)"
149 tristate "PCI PS/2 keyboard and PS/2 mouse controller"
152 Say Y here if you have a Mobility Docking station with PS/2
153 keyboard and mice ports.

166 module will be called maceps2.
169 tristate "PS/2 driver library"
170 depends on SERIO_I8042 || SERIO_I8042=n
172 Say Y here if you are using a driver for device connected
173 to a PS/2 port, such as PS/2 mouse or standard AT keyboard.
175 To compile this driver as a module, choose M here: the
176 module will be called libps2.
179 tristate "Raw access to serio ports"
181 Say Y here if you want to have raw access to serio ports, such as
182 AUX ports on i8042 keyboard controller. Each serio port that is
183 bound to this driver will be accessible via a char device with
184 major 10 and dynamically allocated minor. The driver will try
185 allocating minor 1 (that historically corresponds to /dev/psaux)
186 first. To bind this driver to a serio port use sysfs interface:
188 echo -n "serio_raw" > /sys/bus/serio/devices/serioX/drvctl
190 To compile this driver as a module, choose M here: the
191 module will be called serio_raw.

221 must be loaded from userspace, possibly using udev extras
222 provided keymap helper utility.
224 To compile this driver as a module, choose M here;
225 the module will be called ams_delta_serio.

274 be called hyperv_keyboard.
276 config SERIO_SUN4I_PS2
277 tristate "Allwinner A10 PS/2 controller support"
278 depends on ARCH_SUNXI || COMPILE_TEST
280 This selects support for the PS/2 Host Controller on
