2016-07-11Input: vmmouse - remove port reservationSinclair Yeh1-20/+2
[ Upstream commit 60842ef8128e7bf58c024814cd0dc14319232b6c ] The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource. This causes the port to be reserved by the APCI module as the system comes up, making it unavailable to be reserved again by other drivers, thus preserving this VMWare port for special use in a VMWare guest. This port is designed to be shared among multiple VMWare services, such as the VMMOUSE. Because of this, VMMOUSE should not try to reserve this port on its own. The VMWare non-EFI BIOS does not do this to preserve compatibility with existing/legacy VMs. It is known that there is small chance a VM may be configured such that these ports get reserved by other non-VMWare devices, and if this ever happens, the result is undefined.

2016-02-03Input: elantech - mark protocols v2 and v3 as semi-mtBenjamin Tissoires1-1/+1
[ Upstream commit 6544a1df11c48c8413071aac3316792e4678fbfb ] When using a protocol v2 or v3 hardware, elantech uses the function elantech_report_semi_mt_data() to report data. This devices are rather creepy because if num_finger is 3, (x2,y2) is (0,0). Yes, only one valid touch is reported. Anyway, userspace (libinput) is now confused by these (0,0) touches, and detect them as palm, and rejects them. Commit 3c0213d17a09 ("Input: elantech - fix semi-mt protocol for v3 HW") was sufficient enough for xf86-input-synaptics and libinput before it has palm rejection. Now we need to actually tell libinput that this device is a semi-mt one and it should not rely on the actual values of the 2 touches.

button bits commit 195562194aad3a0a3915941077f283bcc6347b9b upstream. commit 92bac83dd79e ("Input: alps - non interleaved V2 dualpoint has separate stick button bits") assumes that all alps v2 non-interleaved dual point setups have the separate stick button bits. Later we limited this to Dell laptops only because of reports that this broke things on non Dell laptops. Now it turns out that this breaks things on the Dell Latitude D600 too. So it seems that only the Dell Latitude D420/430/620/630, which all share the same touchpad / stick combo, have these separate bits. This patch limits the checking of the separate bits to only these models fixing regressions with other models.

2015-06-05Input: alps - do not reduce trackpoint speed by halfHans de Goede1-3/+2
On some v7 devices (e.g. Lenovo-E550) the deltas reported are typically only in the 0-1 range dividing this by 2 results in a range of 0-0. And even for v7 devices where this does not lead to making the trackstick entirely unusable, it makes it twice as slow as before we added v7 support and were using the ps/2 mouse emulation of the dual point setup. If some kind of generic slowdown is actually necessary for some devices, then that belongs in userspace, not in the kernel.

This commit detects this and treats these touches as non touching.

2015-05-13Input: elantech - fix semi-mt protocol for v3 HWBenjamin Tissoires1-1/+1
When the v3 hardware sees more than one finger, it uses the semi-mt protocol to report the touches. However, it currently works when num_fingers is 0, 1 or 2, but when it is 3 and above, it sends only 1 finger as if num_fingers was 1. This confuses userspace which knows how to deal with extra fingers when all the slots are used, but not when some are missing.

2015-04-15Input: add vmmouse driverThomas Hellstrom6-0/+569
VMMouse enables low-latency mouse-cursor-movements for VMWare and QEMU guests. By removing the guest cursor and using the host as a guest cursor the cursor movement appears instant although in reality there is some lag. To be able to do this, the host's view of the cursor position must exactly match the guest's view and an absolute pointer device is needed. Enter the VMMouse. While the VMMouse driver has historically been an Xorg user-space driver, implementing it as a kernel imput driver enables rootless Xorg and new compositing display servers for VMware guests.

2015-04-13Input: alps - non interleaved V2 dualpoint has separate stick button bitsHans de Goede1-0/+8
Non interleaved V2 dualpoint touchpad / stick combos have separate stick button bits in the touchpad packets, if we do not check these then the trackpoint buttons will not work when using the touchpad, and when pressed when the user starts using the touchpad will report a release event even though the button is still pressed. This commit fixes this by checking the separate bits, note that we simply combine the buttons, since the hardware does the same when using the touchpad buttons with the trackpoint, so we do not have enough information to properly separate them.

2015-04-13Input: alps - fix touchpad buttons getting stuck when used with trackpointHans de Goede1-2/+3
When the left touchpad button gets pressed, and then the trackpoint is moved, and then the button is released, the following happens: 1) touchpad packet is received, touchpad evdev node reports BTN_LEFT 1 2) pointing stick packet is received, the hw will report a BTN_LEFT 1 in this packet because when the trackstick is active it communicates the combined touchpad + pointing stick buttons in the trackstick packet, since alps_report_bare_ps2_packet passes NULL (*) for the dev2 parameter to alps_report_buttons the combining is not detected and the pointing stick evdev node will also report BTN_LEFT 1 3) on release of the button a pointing stick packet with BTN_LEFT 0 is received and the pointing stick evdev node will report BTN_LEFT 0 Note how because of the passing as NULL for dev2 the touchpad evdev node will never send BTN_LEFT 0 in this scenario leading to a stuck mouse button. This is a regression in 4.0 introduced by commit 04aae283ba6a8 ("Input: ALPS - do not mix trackstick and external PS/2 mouse data") This commit fixes this by passing in the touchpad evdev as dev2 parameter when calling alps_report_buttons for the pointingstick on alps v2 devices, so that alps_report_buttons correctly detect that we're already reporting the button as pressed via the touchpad evdev node, and will also send the release event there.

2015-03-09Input: synaptics - remove X250 from the topbuttonpad listBenjamin Tissoires1-1/+0
Lenovo X250 has a PnpID of LEN0046, but it does not have the top software button requirement. For the record, Lenovo T450s and W541 have a PnpID of LEN200f and LEN004a, so they are not on the top software button list.

2015-03-09Input: synaptics - remove X1 Carbon 3rd gen from the topbuttonpad listBenjamin Tissoires1-1/+0
Lenovo decided to switch back to physical buttons for the trackstick on their latest series. The PNPId list was provided before they reverted back to physical buttons, so it contains the new models too. We can know from the touchpad capabilities that the touchpad has physical buttons, so removing the ids from the list is not mandatory. It is still nicer to remove the wrong ids, so start by removing the X1 Carbon 3rd gen, with the PNPId of LEN0048.

2015-03-09Input: synaptics - re-route tracksticks buttons on the Lenovo 2015 seriesBenjamin Tissoires2-11/+41
The 2015 series of the Lenovo thinkpads added back the hardware buttons on top of the touchpad for the trackstick. Unfortunately, they are wired to the touchpad, and not the trackstick. Thus, they are seen as extra buttons from the kernel point of view. This leads to a problem in user space because extra buttons on synaptics devices used to be used as scroll up/down buttons. So in the end, the experience for the user is scroll events for buttons left and right when using the trackstick. Yay! Fortunately, the firmware advertises such behavior in the extended capability $10, and so we can re-route the buttons through the pass-through interface.

2015-03-09Input: synaptics - remove TOPBUTTONPAD property for Lenovos 2015Benjamin Tissoires1-1/+2
The 2015 series of the Lenovo thinkpads added back the hardware buttons on top of the touchpad for the trackstick. Unfortunately, Lenovo used the PNPIDs that are supposed to be "5 buttons" touchpads, so the new laptops also have the INPUT_PROP_TOPBUTTONPAD. Yay! Instead of manually removing each of the new ones, or hoping that we know all the current ones, we can consider that the PNPIDs list that were given contains touchpads that have the trackstick buttons, either physically wired to them, or emulated with the top software button property. Thanks to the extra buttons capability in query $10, we can reliably detect the physical buttons from the software ones, and so we can remove the TOPBUTTONPAD property even if it was declared as such.

On the X1 Carbon 3rd gen (with a 2015 broadwell cpu), the physical middle button of the trackstick (attached to the touchpad serio device, of course) seems to get lost. Actually, the touchpads reports 3 extra buttons, which falls in the switch below to the '2' case. Let's handle the case of odd numbers also, so that the middle button finds its way back.
