Input: elantech - discard the first 2 positions on some firmwares

2011-08-01T20:54:44+00:00

commit 7f29f17b57255b6395046805a98bc663ded63fb8 upstream. According to the Dell/Ubuntu driver, what was previously observed as "jumpy cursor" corresponds to the hardware sending incorrect data for the first two reports of a one touch finger. So let's use the same workaround as in the other driver. Also, detect another firmware version with the same behaviour, as in the other driver.

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

2011-08-01T20:54:43+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()

2011-04-28T15:21:10+00:00

[ upstream commit 708748670c7c6dd5bd3b141473086e6937e72737 ] '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

2011-03-31T18:58:47+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: i8042 - introduce 'notimeout' blacklist for Dell Vostro V13

2011-02-06T19:03:53+00:00

i8042 controller present in Dell Vostro V13 errorneously signals spurious timeouts. Introduce i8042.notimeout parameter for ignoring i8042-signalled timeouts and apply this quirk automatically for Dell Vostro V13, based on DMI match. In addition to that, this machine also needs to be added to nomux blacklist. Signed-off-by: Jiri Kosina Signed-off-by: Dmitry Torokhov Signed-off-by: Andi Kleen

Input: synaptics - fix handling of 2-button ClickPads

2011-02-06T19:03:44+00:00

commit 3bfa321e662edf90fb8123a02c987c2965fa50bb upstream. Lenovo S10-3t's ClickPad is a 2-button ClickPad that reports BTN_LEFT and BTN_RIGHT as normal touchpad, unlike the 1-button ClickPad used in HP mini 210 that reports solely BTN_MIDDLE. In 0xc0-cap response, the 1-button ClickPad has the 20-bit set while 2-button ClickPad has the 8-bit set. This patch makes the kernel only handle 1-button ClickPad specially, and treat 2-button ClickPad in the same fashion as regular touchpads. This fixes kernel bug #18122 and MeeGo bug #4807.

Input: i8042 - add Sony VAIO VPCZ122GX to nomux list

2010-12-14T22:40:17+00:00

[Note that the mainline will not have this particular fix but rather will blacklist entire VAIO line based off DMI board name. For stable I am being a bit more cautious and blacklist one particular product.] Trying to query/activate active multiplexing mode on this VAIO makes both keyboard and touchpad inoperable. Futher kernels will blacklist entire VAIO line, however here we blacklist just one particular model.
