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

2011-05-02T16:19:50+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: synaptics - fix crash in synaptics_module_init()

2011-04-14T20:02:17+00:00

commit 708748670c7c6dd5bd3b141473086e6937e72737 upstream.

'struct dmi_system_id' arrays must always have a terminator to keep
dmi_check_system() from looking at data (and possibly crashing) it
isn't supposed to look at.

The issue went unnoticed until ef8313bb1a22e7d2125d9d758aa8a81f1de91d81,
but was introduced about a year earlier with
7705d548cbe33f18ea7713b9a07aa11047aaeca4 (which also similarly changed
lifebook.c, but the problem there got eliminated shortly afterwards).

The first hunk therefore is a stable candidate back to 2.6.33, while
the full change is needed only on 2.6.38.

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

2011-03-27T18:35:51+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.

Commit 8ee294cd9def0004887da7f44b80563493b0a097 converted serio
subsystem event handling from using a dedicated thread to using
common workqueue. Unfortunately, this regressed our boot times,
due to the fact that serio jobs take long time to execute. While
the new concurrency managed workqueue code manages long-playing
works just fine and schedules additional workers as needed, such
works wreck havoc among remaining users of flush_scheduled_work().

To solve this problem let's move serio/gameport works from system_wq
to system_long_wq which nobody tries to flush.

to the code so that they don't get lost.
