2014-11-21Input: alps - ignore bad data on Dell Latitudes E6440 and E7440Pali Rohár
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.

2014-11-21Input: alps - allow up to 2 invalid packets without resetting devicePali Rohár
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.

2014-11-21Input: alps - ignore potential bare packets when device is out of syncPali Rohár
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.

ForcePads are found on HP EliteBook 1040 laptops. They lack any kind of physical buttons, instead they generate primary button click when user presses somewhat hard on the surface of the touchpad. Unfortunately they also report primary button click whenever there are 2 or more contacts on the pad, messing up all multi-finger gestures (2-finger scrolling, multi-finger tapping, etc). To cope with this behavior we introduce a delay (currently 50 msecs) in reporting primary press in case more contacts appear.

Some elantech v3 touchpad equipped laptops also have a trackpoint, before this commit, these give sync errors. With this patch, the trackpoint is provided as another input device: 'Elantech PS/2 TrackPoint' The patch will also output messages that do not follow the expected pattern. In the mean time I've seen 2 unknown packets occasionally: 0x04 , 0x00 , 0x00 , 0x00 , 0x00 , 0x00 0x00 , 0x00 , 0x00 , 0x02 , 0x00 , 0x00 I don't know what those are for, but they can be safely ignored. Currently all packets that are not known to v3 touchpad and where packet[3] (the fourth byte) lowest nibble is 6 are now recognized as PACKET_TRACKPOINT and processed by the new elantech_report_trackpoint. This has been verified to work on a laptop Lenovo L530 where the touchpad/trackpoint combined identify themselves as: psmouse serio1: elantech: assuming hardware version 3 (with firmware version 0x350f02) psmouse serio1: elantech: Synaptics capabilities query result 0xb9, 0x15, 0x0c.

2014-08-08Input: synaptics - use firmware data for Cr-48Henrik Rydberg
The profile sensor clickpad in a Cr-48 Chromebook does a reasonable job of tracking individual fingers. This tracking isn't perfect, but, experiments show that it works better than just passing "semi-mt" data to userspace, and making userspace try to deduce where the fingers are given a bounding box. This patch tries to report correct two-finger positions instead of the {(min_x, min_y), (max_x, max_y)} for profile sensor clickpads on Cr-48 chromebooks. Note that this device's firmware always reports the higher (smaller y) finger in the "sgm" packet, and the lower (larger y) finger in the "agm" packet. Thus, when a new finger arrives on the pad, the kernel driver uses input core's contact tracking facilities to match contacts with slots.

2014-08-07Input: synaptics - properly initialize slots for semi-MTDmitry Torokhov
Semi-MT devices are pointers too, so let's tell that to input_mt_init_slots(), as well as let it set up the devices as semi-MT, instead of us doing it manually.

2014-08-07Input: MT - make slot cleanup callable outside mt_sync_frame()Henrik Rydberg
Some semi-mt drivers use the slots in a manual way, but may still want to call parts of the frame synchronization logic. This patch makes input_mt_drop_unused callable from those drivers.
