Synaptics image sensor touchpads track up to 5 fingers, but only report 2.

2011-08-23Input: add BTN_TOOL_QUINTTAP for reporting 5 fingers on touchpadDaniel Kurtz1-0/+1
"4-finger scroll" is a gesture supported by some applications and operating systems. "Resting thumb" is when a clickpad user rests a finger (e.g., a thumb), in a "click zone" (typically the bottom of the touchpad) in anticipation of click+move=select gestures. Thus, "4-finger scroll + resting thumb" is a 5-finger gesture. To allow userspace to detect this gesture, we send BTN_TOOL_QUINTTAP.

2011-08-23Input: synaptics - process finger (<=3) transitionsDaniel Kurtz2-16/+278
Synaptics image sensor touchpads track 5 fingers, but only report 2. This patch attempts to deal with some idiosyncrasies of these touchpads: * When there are 3 or more fingers, only two are reported. * The touchpad tracks the 5 fingers in slot[0] through slot[4]. * It always reports the lowest and highest valid slots in SGM and AGM packets, respectively. * The number of fingers is only reported in the SGM packet. However, the number of fingers can change either before or after an AGM packet. * Thus, if an SGM reports a different number of fingers than the last SGM, it is impossible to tell whether the intervening AGM corresponds to the old number of fingers or the new number of fingers. * For example, when going from 2->3 fingers, it is not possible to tell whether tell AGM contains slot[1] (old 2nd finger) or slot[2] (new 3rd finger). * When fingers are added one at at time, from 1->2->3, it is possible to track which slots are contained in the SGM and AGM packets: 1 finger: SGM = slot[0], no AGM 2 fingers: SGM = slot[0], AGM = slot[1] 3 fingers: SGM = slot[0], AGM = slot[2] * It is also possible to track which slot is contained in the SGM when 1 of 2 fingers is removed. This is because the touchpad sends a special (0,0,0) AGM packet whenever all fingers are removed except slot[0]: Last AGM == (0,0,0): SGM contains slot[1] Else: SGM contains slot[0] * However, once there are 3 fingers, if exactly 1 finger is removed, it is impossible to tell which 2 slots are contained in SGM and AGM. The (SGM,AGM) could be (0,1), (0,2), or (1,2). There is no way to know. * Similarly, if two fingers are simultaneously removed (3->1), then it is only possible to know if SGM still contains slot[0]. * Since it is not possible to reliably track which slot is being reported, we invalidate the tracking_id every time the number of fingers changes until this ambiguity is resolved when: a) All fingers are removed. b) 4 or 5 fingers are touched, generates an AGM-CONTACT packet. c) All fingers are removed except slot[0]. In this special case, the ambiguity is resolved since by the (0,0,0) AGM packet. Behavior of the driver: When 2 or more fingers are present on the touchpad, the kernel reports up to two MT-B slots containing the position data for two of the fingers reported by the touchpad. If the identity of a finger cannot be tracked when the number-of-fingers changes, the corresponding MT-B slot will be invalidated (track_id set to -1), and a new track_id will be assigned in a subsequent input event report. The driver always reports the total number of fingers using one of the EV_KEY/BTN_TOOL_*TAP events. This could differ from the number of valid MT-B slots for two reasons: a) There are more than 2 fingers on the pad. b) During ambiguous number-of-fingers transitions, the correct track_id for one or both of the slots cannot be determined, so the slots are invalidated. Thus, this is a hybrid singletouch/MT-B scheme. Userspace can detect this behavior by noting that the driver supports more EV_KEY/BTN_TOOL_*TAP events than its maximum EV_ABS/ABS_MT_SLOT.

2011-08-23Input: synaptics - decode AGM packet typesDaniel Kurtz2-7/+43
A Synaptics image sensor tracks 5 fingers, but can only report 2. The algorithm for choosing which 2 fingers to report and in which packet: Touchpad maintains 5 slots, numbered 0 to 4 Initially all slots are empty As new fingers are detected, assign them to the lowest available slots The touchpad always reports: SGM: lowest numbered non-empty slot AGM: highest numbered non-empty slot, if there is one In addition, these touchpads have a special AGM packet type which reports the number of fingers currently being tracked, and which finger is in each of the two slots. Unfortunately, these "TYPE=2" packets are only used when more than 3 fingers are being tracked. When less than 4 fingers are present, the 'w' value must be used to track how many fingers are present, and knowing which fingers are being reported is much more difficult, if not impossible.

2011-08-23Input: synaptics - add image sensor supportDaniel Kurtz2-17/+110
Synaptics makes (at least) two kinds of touchpad sensors: * Older pads use a profile sensor that could only infer the location of individual fingers based on the projection of their profiles onto row and column sensors. * Newer pads use an image sensor that can track true finger position using a two-dimensional sensor grid. Both sensor types support an "Advanced Gesture Mode": When multiple fingers are detected, the touchpad sends alternating "Advanced Gesture Mode" (AGM) and "Simple Gesture Mode" (SGM) packets. The AGM packets have w=2, and contain reduced resolution finger data The SGM packets have w={0,1} and contain full resolution finger data Profile sensors try to report the "upper" (larger y value) finger in the SGM packet, and the lower (smaller y value) in the AGM packet. However, due to the nature of the profile sensor, they easily get confused when fingers cross, and can start reporting the x-coordinate of one with the y-coordinate of the other. Thus, for profile sensors, "semi-mt" was created, which reports a "bounding box" created by pairing min and max coordinates of the two pairs of reported fingers. Image sensors can report the actual coordinates of two of the fingers present. This patch detects if the touchpad is an image sensor and reports finger data using the MT-B protocol. NOTE: This patch only adds partial support for 2-finger gestures. The proper interpretation of the slot contents when more than two fingers are present is left to later patches. Also, handling of 'number of fingers' transitions is incomplete.
