2013-02-08dix: support the transformation matrix for relative devices.Peter Hutterer1-2/+25
The transformation matrix we previously stored was a scaled matrix based on the axis ranges of the device. For relative movements, the scaling is not required (or desired). Store two separate matrices, one as requested by the client, one as the product of [scale . matrix . inv_scale]. Depending on the type of movement, apply the respective matrix. For relative movements, also drop the translation component since it doesn't really make sense to use that bit.

2013-02-08dix: pre-scale relative events from abs devices to desktop ratio (#31636)Peter Hutterer1-2/+24
Absolute devices may send relative events depending on the mode (synaptics by default, wacom per option). The relative events are added to the previous position, converted into device coordinates and then scaled into desktop coordinates for pointer movement. Because the device range must be mapped into the desktop coordinate range, this results in uneven scaling depending dimensions, e.g. on a setup with width == 2 * height, a relative movement of 10/10 in device coordinates results in a cursor movement of 20/10 (+ acceleration) Other commonly user-visible results: * the touchpad changing acceleration once an external monitor as added. * drawing a circle on a wacom tablet in relative mode gives an ellipsis in the same ratio as the desktop dimensions. Solution: pre-scale the incoming relative x/y coordinates by width/height ratio of the total desktop size. Then add them to the previous coordinates and scale back with the previous mapping, which will undo the pre-scaling and give us the right movement.

In WarpPointer calls, we get input in screen coordinates. They must be scaled to device coordinates, and then back to screen coordinates for screen crossing and root coordinates in events. The rounding errors introduced (and clipping in core/XI 1.x events) can lead to the actual position being different to the requested input coordinates. e.g. 200 scales to 199.9999, truncated to 199 in the event. Avoid this by simply overwriting the scaled screen coordinates with the input coordinates for the POINTER_SCREEN case.

2012-03-22dix: add dtrace probes to input APIPeter Hutterer1-0/+42
For driver debugging, it is helpful to know whether the driver has actually submitted an event to the server. dtrace hooks can help here. Note that GetPointerEvents and friends may also be triggered by the server for other emulated devices, some care must be taken when analysing the results. Additional difficulty: proximity events have a run-time assigned type, so this may make automatic detection a tad harder. If in doubt, go for any event > 64 since the only two that can have that value are ProximityIn and ProximityOut. An example systemtap script is below: # Compile+run with # stap -g xorg.stp /usr/bin/Xorg # function print_valuators:string(nvaluators:long, mask_in:long, valuators_in:long) %{ int i; unsigned char *mask = (unsigned char*)THIS->mask_in; double *valuators = (double*)THIS->valuators_in; char str[128] = {0}; char *s = str; #define BitIsSet(ptr, bit) (((unsigned char*)(ptr))[(bit)>>3] & (1 << ((bit) & 7))) s += sprintf(s, "nval: %d ::", (int)THIS->nvaluators); for (i = 0; i < THIS->nvaluators; i++) { s += sprintf(s, " %d: ", i); if (BitIsSet(mask, i)) s += sprintf(s, "%d", (int)valuators[i]); } sprintf(THIS->__retvalue, "%s", str); %} probe process(@1).mark("input__event") { deviceid = $arg1 type = $arg2 detail = $arg3 flags = $arg4 nvaluators = $arg5 str = print_valuators(nvaluators, $arg6, $arg7) printf("Event: device %d type %d detail %d flags %#x %s\n", deviceid, type, detail, flags, str); } Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Acked-by: Jeremy Huddleston <jeremyhu@apple.com>
