commit 20e2f66c4b38429853ef98689d359451be087de3 (HEAD, master) Author: Rui Paulo Date: Sun Apr 5 20:51:35 2015 Improve Synaptics support for newer touchpads. Enable two finger scrolling by default and disable the edge scrolling if the touchpad has no physical zone for it. Disable directional scrolling by default to avoid using extended buttons as scroll buttons. Add support for ClickPad. On Lenovo laptops, this is the button reported when one presses the touchpad. While there, fix a problem where the extended button where not reporting the button release event correctly: we need to save the state of the buttons and report it to sysmouse until we receive a packet from the touchpad indicating the button has been released. This makes it possible to use an extended button to resize a window. On Lenovo laptops, the major buttons are actually reported as extended buttons. Tested on a Lenovo X1 (3rd gen). diff --git a/sys/dev/atkbdc/psm.c b/sys/dev/atkbdc/psm.c index 5703daf..3c3a27c 100644 --- a/sys/dev/atkbdc/psm.c +++ b/sys/dev/atkbdc/psm.c @@ -198,6 +198,7 @@ typedef struct synapticsinfo { struct sysctl_ctx_list sysctl_ctx; struct sysctl_oid *sysctl_tree; int directional_scrolls; + int two_finger_scroll; int min_pressure; int max_pressure; int max_width; @@ -336,6 +337,7 @@ struct psm_softc { /* Driver status information */ int lasterr; int cmdcount; struct sigio *async; /* Processes waiting for SIGIO */ + int extended_buttons; }; static devclass_t psm_devclass; @@ -2752,7 +2754,15 @@ proc_synaptics(struct psm_softc *sc, packetbuf_t *pb, mousestatus_t *ms, if (pb->ipacket[5] & 0x02) touchpad_buttons |= MOUSE_BUTTON7DOWN; } else { - touchpad_buttons |= MOUSE_BUTTON2DOWN; + if (pb->ipacket[4] & 0x01) + touchpad_buttons |= MOUSE_BUTTON1DOWN; + if (pb->ipacket[5] & 0x01) + touchpad_buttons |= MOUSE_BUTTON3DOWN; + if (pb->ipacket[4] & 0x02) + touchpad_buttons |= MOUSE_BUTTON2DOWN; + if (pb->ipacket[5] & 0x02) + touchpad_buttons |= MOUSE_BUTTON4DOWN; + sc->extended_buttons = touchpad_buttons; } /* @@ -2774,13 +2784,25 @@ proc_synaptics(struct psm_softc *sc, packetbuf_t *pb, mousestatus_t *ms, mask = (1 << maskedbits) - 1; pb->ipacket[4] &= ~(mask); pb->ipacket[5] &= ~(mask); + } else if (!sc->syninfo.directional_scrolls) { + /* + * Keep reporting MOUSE DOWN until we get a new packet + * indicating otherwise. + */ + touchpad_buttons |= sc->extended_buttons; } } + /* Handle ClickPad. */ + if (sc->synhw.capClickPad && + ((pb->ipacket[0] ^ pb->ipacket[3]) & 0x01)) + touchpad_buttons |= MOUSE_BUTTON1DOWN; ms->button = touchpad_buttons | guest_buttons; - /* Check pressure to detect a real wanted action on the - * touchpad. */ + /* + * Check pressure to detect a real wanted action on the + * touchpad. + */ if (*z >= sc->syninfo.min_pressure) { synapticsaction_t *synaction; int cursor, peer, window; @@ -2793,7 +2815,7 @@ proc_synaptics(struct psm_softc *sc, packetbuf_t *pb, mousestatus_t *ms, int weight_current, weight_previous, weight_len_squared; int div_min, div_max, div_len; int vscroll_hor_area, vscroll_ver_area; - + int two_finger_scroll; int len, weight_prev_x, weight_prev_y; int div_max_x, div_max_y, div_x, div_y; @@ -2820,6 +2842,7 @@ proc_synaptics(struct psm_softc *sc, packetbuf_t *pb, mousestatus_t *ms, div_len = sc->syninfo.div_len; vscroll_hor_area = sc->syninfo.vscroll_hor_area; vscroll_ver_area = sc->syninfo.vscroll_ver_area; + two_finger_scroll = sc->syninfo.two_finger_scroll; /* Palm detection. */ if (!( @@ -2980,23 +3003,35 @@ proc_synaptics(struct psm_softc *sc, packetbuf_t *pb, mousestatus_t *ms, dxp >= sc->syninfo.vscroll_min_delta || dyp >= sc->syninfo.vscroll_min_delta) { /* Check for horizontal scrolling. */ - if ((vscroll_hor_area > 0 && + if (!two_finger_scroll && + ((vscroll_hor_area > 0 && synaction->start_y <= vscroll_hor_area) || (vscroll_hor_area < 0 && synaction->start_y >= - 6143 + vscroll_hor_area)) + 6143 + vscroll_hor_area))) synaction->in_vscroll += 2; /* Check for vertical scrolling. */ - if ((vscroll_ver_area > 0 && + if (!two_finger_scroll && + ((vscroll_ver_area > 0 && synaction->start_x <= vscroll_ver_area) || (vscroll_ver_area < 0 && synaction->start_x >= - 6143 + vscroll_ver_area)) + 6143 + vscroll_ver_area))) synaction->in_vscroll += 1; + /* + * Handle two finger scrolling. + */ + if (w == 0 && two_finger_scroll) { + if (dyp) + synaction->in_vscroll += 2; + if (dxp) + synaction->in_vscroll += 1; + } + /* Avoid conflicts if area overlaps. */ - if (synaction->in_vscroll == 3) + if (synaction->in_vscroll >= 3) synaction->in_vscroll = (dxp > dyp) ? 2 : 1; } @@ -3247,6 +3282,7 @@ SYNAPTICS_END: * That's why the horizontal wheel is disabled by * default for now. */ + if (ms->button & MOUSE_BUTTON4DOWN) { *z = -1; ms->button &= ~MOUSE_BUTTON4DOWN; @@ -3460,7 +3496,7 @@ psmsoftintr(void *arg) c = ((x < 0) ?
