2017-08-30Input: ALPS - fix two-finger scroll breakage in right side on ALPS touchpadMasaki Ota
commit 4a646580f793d19717f7e034c8d473b509c27d49 upstream. Fixed the issue that two finger scroll does not work correctly on V8 protocol. The cause is that V8 protocol X-coordinate decode is wrong at SS4 PLUS device. I added SS4 PLUS X decode definition. Mote notes: the problem manifests itself by the commit e7348396c6d5 ("Input: ALPS - fix V8+ protocol handling (73 03 28)"), where a fix for the V8+ protocol was applied. Although the culprit must have been present beforehand, the two-finger scroll worked casually even with the wrongly reported values by some reason. It got broken by the commit above just because it changed x_max value, and this made libinput correctly figuring the MT events. Since the X coord is reported as falsely doubled, the events on the right-half side go outside the boundary, thus they are no longer handled. This resulted as a broken two-finger scroll. One finger event is decoded differently, and it didn't suffer from this problem. The problem was only about MT events. --tiwai Fixes: e7348396c6d5 ("Input: ALPS - fix V8+ protocol handling (73 03 28)") Signed-off-by: Masaki Ota <masaki.ota@jp.alps.com> Tested-by: Takashi Iwai <tiwai@suse.de> Tested-by: Paul Donohue <linux-kernel@PaulSD.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit 864db9295b06837d11a260e5dacf99a3fdf6bce2 upstream. The current Alps SS5 (SS4 v2) code generates bogus TouchPad events when TrackStick packets are processed. This causes the xorg synaptics driver to print "unable to find touch point 0" and "BUG: triggered 'if (priv->num_active_touches > priv->num_slots)'" messages. It also causes unexpected TouchPad button release and re-click event sequences if the TrackStick is moved while holding a TouchPad button. This commit corrects the problem by adjusting alps_process_packet_ss4_v2() so that it only sends TrackStick reports when processing TrackStick packets.

2016-11-17Input: psmouse - disable automatic probing of BYD touchpadsDmitry Torokhov
BYD automatic protocol detection is extremely unreliable and is often triggers false positives on regular mice, Sentelic touchpads, and other devices. BYD has several documents that have recommended detection sequence, but they conflict with each other and, as far as I can see, still would not produce unique enough output to reliably differentiate BYD from other PS/2 devices. OEMs sourcing BYD devices also do not do us any favors by not supplying any reasonable DMI data and instead leaving turds like "To Be Filled By O.E.M." in place of vendor data, or "System Serial Number" as serial number. On top of that BYD is not truly modern multitouch controller, but rather a single-touch transitional device that only reports absolute coordinates at the beginning of finger contact and then reverts to reporting displacements, and thus not very precise; the only benefit from using BYD mode vs the legacy PS/2 mode is possibility of edge scrolling. Given the above, and the fact that BYD devices are somewhat uncommon, let's disable automatic detection of BYD devices. Users who know they have BYD trackpads or want to experiment can attempt to activate BYD protocol via sysfs: echo -n "byd" > /sys/bus/serio/devices/serio1/drvctl Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=151691 Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=175421 Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=120781 Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=121281 Fixes: 98ee37714493 ("Input: byd - add BYD PS/2 touchpad driver") Cc: stable@vger.kernel.org # 4.6+ Reviewed-by: Pali Rohár <pali.rohar@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2016-06-24Input: vmmouse - remove port reservationSinclair Yeh
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.

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.

2016-01-07Input: ALPS - report v3 pinnacle trackstick device only if is presentPali Rohár
This patch moves v3 pinnacle code for trackstick detection from alps_hw_init_v3() to alps_set_protocol() so ALPS_DUALPOINT flag can be cleared before registering trackstick input device in kernel.

2016-01-07Input: ALPS - detect trackstick presence for v7 protocolPali Rohár
This patch adds detection of trackstick for v7 protocol devices. Code in this patch is used in official Dell touchpad linux drivers for Dell models: Dell Latitude E5250/5250, E5450/5450, E5550/5550 Detection code and base reg for alps v3 rushmore and v7 devices is exacly same. Also user in bug https://bugzilla.kernel.org/show_bug.cgi?id=94801 reported that Toshiba Sattellite Z30-A-1DG has only alps v7 touchpad device without trackstick and kernel reports to userspace also redundant trackstick device.

2015-12-17Merge branch 'psmouse-passthrough' into nextDmitry Torokhov
Bring in changes to limit number of protocols we try on pass-though PS/2 ports so that probe ocmpletes faster.

This makes Logitech PS2++ protocol implementation consistent with the naming in other protocols. Also mark the stub as "static inline" Reviewed-by: Hans de Goede <hdegoede@redhat.com> Tested-by: Marcin Sochacki <msochacki+kernel@gmail.com> Tested-by: Till <till2.schaefer@uni-dortmund.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-12-17Input: psmouse - limit protocols that we try on passthrough portsDmitry Torokhov
PS/2 protocol is slow, and using it with pass-through port (where we encapsulate PS/2 into PS/2) is slower yet so it takes quite a bit of time to do full protocol discovery for device attached to a pass-through port. However, so far we have not see anything but trackpoints or basic PS/2 mice on pass-through ports, so let's limit protocols that we probe there to Trackpoint, IntelliMouse Explorer, IntelliMouse, and bare PS/2 protocol, and avoid other extended protocols, such as Synaptics, ALPS, etc. Reviewed-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Pali Rohár <pali.rohar@gmail.com> Tested-by: Marcin Sochacki <msochacki+kernel@gmail.com> Tested-by: Till <till2.schaefer@uni-dortmund.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
