2016-02-25Input: i8042 - add Fujitsu Lifebook U745 to the nomux listAurélien Francillon1-0/+7
commit dd0d0d4de582a6a61c032332c91f4f4cb2bab569 upstream. Without i8042.nomux=1 the Elantech touch pad is not working at all on a Fujitsu Lifebook U745. This patch does not seem necessary for all U745 (maybe because of different BIOS versions?). However, it was verified that the patch does not break those (see opensuse bug 883192: https://bugzilla.opensuse.org/show_bug.cgi?id=883192).

2016-02-25Input: elantech - mark protocols v2 and v3 as semi-mtBenjamin Tissoires1-1/+1
commit 6544a1df11c48c8413071aac3316792e4678fbfb upstream. 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.

commit 66bc2f51ef7deabc8b8f3baa98ae64b65e5e973a upstream.

2015-09-30Input: evdev - do not report errors form flush()Takashi Iwai1-9/+4
commit eb38f3a4f6e86f8bb10a3217ebd85ecc5d763aae upstream. We've got bug reports showing the old systemd-logind (at least system-210) aborting unexpectedly, and this turned out to be because of an invalid error code from close() call to evdev devices. close() is supposed to return only either EINTR or EBADFD, while the device returned ENODEV. logind was overreacting to it and decided to kill itself when an unexpected error code was received. What a tragedy. The bad error code comes from flush fops, and actually evdev_flush() returns ENODEV when device is disconnected or client's access to it is revoked. But in these cases the fact that flush did not actually happen is not an error, but rather normal behavior. For non-disconnected devices result of flush is also not that interesting as there is no potential of data loss and even if it fails application has no way of handling the error. Because of that we are better off always returning success from evdev_flush(). Also returning EINTR from flush()/close() is discouraged (as it is not clear how application should handle this error), so let's stop taking evdev->mutex interruptibly.

2015-08-19Input: usbtouchscreen - avoid unresponsive TSC-30 touch screenBernhard Bender1-0/+3
commit 968491709e5b1aaf429428814fff3d932fa90b60 upstream. This patch fixes a problem in the usbtouchscreen driver for DMC TSC-30 touch screen. Due to a missing delay between the RESET and SET_RATE commands, the touch screen may become unresponsive during system startup or driver loading. According to the DMC documentation, a delay is needed after the RESET command to allow the chip to complete its internal initialization. As this delay is not guaranteed, we had a system where the touch screen occasionally did not send any touch data. There was no other indication of the problem. The patch fixes the problem by adding a 150ms delay between the RESET and SET_RATE commands.

commit 3c0213d17a09601e0c6c0ae0e27caf70d988290f upstream. 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.

commit 1a48ff81b3912be5fadae3fafde6c2f632246a4c upstream. Xbox One controllers require an initialization message to start sending data, so xpad_init_output becomes a required function. The Xbox One controller does not have LEDs like the Xbox 360 controller, so that functionality is not implemented. The format of messages controlling rumble is currently undocumented, so rumble support is not yet implemented. Note that Xbox One controller advertises three interfaces with the same interface class, subclass and protocol, so we have to also match against interface number.

2014-12-06Input: synaptics - change min/max quirk table to pnp-id matchingHans de Goede1-113/+36
commit 0f68f39c393bc06ac5ccc8794f0e2ed841e41c3e upstream. Most of the affected models share pnp-ids for the touchpad. So switching to pnp-ids give us 2 advantages: 1) It shrinks the quirk list 2) It will lower the new quirk addition frequency, ie the recently added W540 quirk would not have been necessary since it uses the same LEN0034 pnp ids as other models already added before it As an added bonus it actually puts the quirk on the actual psmouse, rather then on the machine, which is technically more correct.

2014-12-06Input: serio - add firmware_id sysfs attributeHans de Goede1-0/+13
commit 0456c66f4e905e1ca839318219c770988b47975c upstream. serio devices exposed via platform firmware interfaces such as ACPI may provide additional identifying information of use to userspace. We don't associate the serio devices with the firmware device (we don't set it as parent), so there's no way for userspace to make use of this information. We cannot change the parent for serio devices instantiated though a firmware interface as that would break suspend / resume ordering. Therefore this patch adds a new firmware_id sysfs attribute so that userspace can get a string from there with any additional identifying information the firmware interface may provide.

2014-11-19Input: alps - ignore bad data on Dell Latitudes E6440 and E7440Pali Rohár1-0/+15
commit a7ef82aee91f26da79b981b9f5bca43b8817d3e4 upstream. Sometimes on Dell Latitude laptops psmouse/alps driver receive invalid ALPS protocol V3 packets with bit7 set in last byte. More often it can be reproduced on Dell Latitude E6440 or E7440 with closed lid and pushing cover above touchpad. If bit7 in last packet byte is set then it is not valid ALPS packet. I was told that ALPS devices never send these packets. It is not know yet who send those packets, it could be Dell EC, bug in BIOS and also bug in touchpad firmware... With this patch alps driver does not process those invalid packets, but instead of reporting PSMOUSE_BAD_DATA, getting into out of sync state, getting back in sync with the next byte and spam dmesg we return PSMOUSE_FULL_PACKET. If driver is truly out of sync we'll fail the checks on the next byte and report PSMOUSE_BAD_DATA then.

2014-11-19Input: alps - allow up to 2 invalid packets without resetting devicePali Rohár1-0/+3
commit 9d720b34c0a432639252f63012e18b0507f5b432 upstream. On some Dell Latitude laptops ALPS device or Dell EC send one invalid byte in 6 bytes ALPS packet. In this case psmouse driver enter out of sync state. It looks like that all other bytes in packets are valid and also device working properly. So there is no need to do full device reset, just need to wait for byte which match condition for first byte (start of packet). Because ALPS packets are bigger (6 or 8 bytes) default limit is small. This patch increase number of invalid bytes to size of 2 ALPS packets which psmouse driver can drop before do full reset. Resetting ALPS devices take some time and when doing reset on some Dell laptops touchpad, trackstick and also keyboard do not respond. So it is better to do it only if really necessary.

2014-11-19Input: alps - ignore potential bare packets when device is out of syncPali Rohár1-1/+7
commit 4ab8f7f320f91f279c3f06a9795cfea5c972888a upstream. 5th and 6th byte of ALPS trackstick V3 protocol match condition for first byte of PS/2 3 bytes packet. When driver enters out of sync state and ALPS trackstick is sending data then driver match 5th, 6th and next 1st bytes as PS/2. It basically means if user is using trackstick when driver is in out of sync state driver will never resync. Processing these bytes as 3 bytes PS/2 data cause total mess (random cursor movements, random clicks) and make trackstick unusable until psmouse driver decide to do full device reset. Lot of users reported problems with ALPS devices on Dell Latitude E6440, E6540 and E7440 laptops. ALPS device or Dell EC for unknown reason send some invalid ALPS PS/2 bytes which cause driver out of sync. It looks like that i8042 and psmouse/alps driver always receive group of 6 bytes packets so there are no missing bytes and no bytes were inserted between valid ones. This patch does not fix root of problem with ALPS devices found in Dell Latitude laptops but it does not allow to process some (invalid) subsequence of 6 bytes ALPS packets as 3 bytes PS/2 when driver is out of sync. So with this patch trackstick input device does not report bogus data when also driver is out of sync, so trackstick should be usable on those machines.
