Input: xen-kbdfront - fix mouse getting stuck after save/restore

2011-05-09T23:04:42+00:00

commit c36b58e8a9112017c2bcc322cc98e71241814303 upstream.

Mouse gets "stuck" after restore of PV guest but buttons are in working
condition.

If driver has been configured for ABS coordinates at start it will get
XENKBD_TYPE_POS events and then suddenly after restore it'll start getting
XENKBD_TYPE_MOTION events, that will be dropped later and they won't get
into user-space.

Regression was introduced by hunk 5 and 6 of
5ea5254aa0ad269cfbd2875c973ef25ab5b5e9db
("Input: xen-kbdfront - advertise either absolute or relative
coordinates").

Driver on restore should ask xen for request-abs-pointer again if it is
available. So restore parts that did it before 5ea5254.

Input: xen-kbdfront - advertise either absolute or relative coordinates

2011-03-28T14:31:23+00:00

commit 8c3c283e6bf463ab498d6e7823aff6c4762314b6 upstream.

A virtualized display device is usually viewed with the vncviewer
application, either by 'xm vnc domU' or with vncviewer localhost:port.
vncviewer and the RFB protocol provides absolute coordinates to the
virtual display. These coordinates are either passed through to a PV
guest or converted to relative coordinates for a HVM guest.

A PV guest receives these coordinates and passes them to the kernels
evdev driver. There it can be picked up by applications such as the
xorg-input drivers. Using absolute coordinates avoids issues such as
guest mouse pointer not tracking host mouse pointer due to wrong mouse
acceleration settings in the guests X display.

Advertise either absolute or relative coordinates to the input system
and the evdev driver, depending on what dom0 provides. The xorg-input
driver prefers relative coordinates even if a devices provides both.

Input: joydev - fix JSIOCSAXMAP ioctl

2011-03-21T19:43:14+00:00

commit d2520a426dc3033c00077e923a553fc6c98c7564 upstream.

Fixed JSIOCSAXMAP ioctl to update absmap, the map from hardware axis to
event axis in addition to abspam.  This fixes a regression introduced
by 999b874f.

Input: twl40300-keypad - fix handling of "all ground" rows

2010-08-02T17:26:40+00:00

commit 3fea60261e73dbf4a51130d40cafcc8465b0f2c3 upstream.

The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c)
defines a key map for the matrix keypad keyboard. The hardware seems to
use all of the 8 rows and 8 columns of the keypad, although not all
possible locations are used.

The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys
are defined with a row and column number between 0 and 7, except

        KEY(0xff, 2, KEY_F9),
        KEY(0xff, 4, KEY_F10),
        KEY(0xff, 5, KEY_F11),

which represent keycodes that should be emitted when entire row is
connected to the ground.  since the driver handles this case as if we
had an extra column in the key matrix. Unfortunately we do not allocate
enough space and end up owerwriting some random memory.

Input: psmouse - reset all types of mice before reconnecting

2010-07-05T18:16:11+00:00

commit ef110b24e28f36620f63dab94708a17c7e267358 upstream.

Synaptics hardware requires resetting device after suspend to ram
in order for the device to be operational. The reset lives in
synaptics-specific reconnect handler, but it is not being invoked
if synaptics support is disabled and the device is handled as a
standard PS/2 device (bare or IntelliMouse protocol).

Let's add reset into generic reconnect handler as well.

Input: wacom - switch mode upon system resume

2010-04-26T14:47:54+00:00

commit 014f61504af276ba9d9544d8a7401d8f8526eb73 upstream.

When Wacom devices wake up from a sleep, the switch mode command
(wacom_query_tablet_data) is needed before wacom_open is called.
wacom_query_tablet_data should not be executed inside wacom_open
since wacom_open is called more than once during probe.

wacom_retrieve_hid_descriptor is removed from wacom_resume due
to the fact that the required descriptors are stored properly
upon system resume.
