NAME
inputtest - An X.Org input driver for testing
SYNOPSIS

Identifier "devname"
Driver "inputtest"

DESCRIPTION
inputtest is an Xorg input driver that passes events received over a
socket on to the server as input events. It supports the full set of
the xf86 driver APIs exposed by Xorg. The primary use cases of this in-
put driver are various integration tests that need to interface with
the input subsystem.
CONFIGURATION DETAILS
Please refer to xorg.conf(5) for general configuration details and for
options that can be used with all input drivers. This section only
covers configuration details specific to this driver.
External process can communicate with the input driver via a named
socket that is created after the driver is initialized. The paths to
the socket is passed via input driver options.
The following driver Options are supported:
Option "SocketPath" "string"
Sets the path where the driver will create a named socket. Any
existing file at that location will be removed.
Option "DeviceType" "string"
Sets the type of the device to be emulated.
Keyboard Initializes a keyboard device.
Pointer Initializes a relative-mode pointer device. It will have
four valuators - a "Rel X" valuator at axis 0 and a "Rel Y" val-
uator at axis 1. A horizontal scroll valuator will be set up at
axis 2. A vertical scroll valuator will be set up at axis 3.
PointerAbsolute Initializes an absolute-mode pointer device. It
will have four valuators - an "Abs X" valuator at axis 0 and an
"Abs Y" valuator at axis 1. A horizontal scroll valuator will
be set up at axis 2. A vertical scroll valuator will be set up
at axis 3.
PointerAbsoluteProximity Initializes an absolute-mode pointer
device with proximity support. The valuators are initialized in
the same way as for PointerAbsolute type.
Touch Initializes a touch device. It will have 5 valuators: an
"Abs MT Position X" at axis 0, an "Abs MT Position Y" valuator
at axis 1, a horizontal scroll valuator on axis 2, a vertical
scroll valuator on axis 3 and an "Abs MT Pressure" valuator at
axis 4.
Option "TouchCount" "int"
Sets the maximum number of simultaneous touches for touch de-
vices.
Option "PointerButtonCount" "int"
Sets the maximum number of buttons in pointer devices.
Option "PointerHasPressure" "bool"
Selects whether "Abs Pressure" is available at the axis 4 in
pointer devices.
INTERFACE WITH THE DRIVER
The communication with the driver is a binary protocol defined in in-
clude/xf86-input-inputtest-protocol.h
At the beginning, the client process that communicates with the driver
must connect to the socket that is created by the driver at SocketPath.
Once the connection is established, it must write a xf86ITEvent-
ClientVersion event and read a xf86ITResponseServerVersion response
where the driver specifies the protocol version supported by it. If
this version is lower than requested by the client, then the driver
will disconnect.
After receiving xf86ITResponseServerVersion message the client may send
events to the driver. Each event is an instance of one of the
xf86ITEvent* structs. The length field defines the full length of the
struct in bytes and the event field defines the type of the struct.
The responses from the server follow the same structure. Each response
is an instance of one of the xf86ITResponse* structs. The length field
defines the full length of the struct in bytes and the event field de-
fines the type of the struct.
The synchronization with Xorg is performed via xf86ITEventWaitForSync
event. After sending such event, the client must read of a xf86ITRe-
sponseSyncFinishedeventfromthesocketwithoutsendingadditional events.
The completion of the read operation indicates that Xorg has fully pro-
cessed all input events sent to it so far.
