| * hid: egalax: Convert to MT slotsHenrik Rydberg2010-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | The firmware in the joojoo reports touches sequentially, one per report, which confuses the current driver. A further complication is the absense of any indication of a touch frame. This patch converts the driver to the MT slots protocol, and outputs one full touch frame per report. This way, proper handling for both firmwares is ensured.

| * input: mt: Add hovering distance axisHenrik Rydberg2010-12-16
| | | | | | | | | | | | | | | | | | | | Touch devices capable of hovering, i.e., fingers detected a distance from the surface, are not supported by the current input MT protocol. This patch adds ABS_MT_DISTANCE, which may be used to indicate the distance between the contact and the surface. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
| * input: mt: Move tracking and pointer emulation to input-mtHenrik Rydberg2010-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The drivers using the type B protocol all report tracking information the same way. The contact id is semantically equivalent to ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates the driver. The situation can be improved upon by providing a common pointer emulation code, thereby removing the need for the tracking id in the driver. This patch moves all tracking event handling over to the input core, simplifying both the existing drivers and the ones currently in preparation.

* | Input: serio HIL MLC - don't deref null, don't leak and return proper errorJesper Juhl2010-11-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While reviewing various users of kernel memory allocation functions I came across drivers/input/serio/hil_mlc.c::hil_mlc_register() and noticed that: - it calls kzalloc() but fails to check for a NULL return before use. - it makes several allocations and if one fails it doesn't free the previous ones. - It doesn't return -ENOMEM in the failed memory allocation case (it just crashes). This patch corrects all of the above and also reworks the only caller of this function that I could find (drivers/input/serio/hp_sdc_mlc.c::hp_sdc_mlc_out()) so that it now checks the return value of hil_mlc_register() and properly propagates it on failure and I also restructured the code to remove some labels and goto's to make it, IMHO nicer to read.

| | | | | | | | | | | | | | | | | | | | | | | | | | As pointed out by Oliver Neukum: xpad->irq_in is currently submitted before xpad->bulk_out is allocated. That however is a race, because the callback for irq_in can call xpad360w_process_packet(), which will in turn submit the bulk URB. This patch moves initialization for xpad->bulk_out earlier, so we can ensure xpad->bulk_out is initialized before submitting urb.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old implementation of spew detection simply tracked the overall position delta of the cursor over every 100 packets. We found that this causes occasional false positives in spew detection, and also that the conditions of the spewy packets are perhaps more fixed than we once thought. Rework the spew detection to look for packets of specific small delta, and only recalibrating if the overall movement delta stays within expected bounds. Also discard duplicate packets in the advanced mode, which appear to be very common. If we don't, the spew detection kicks in far too early. If we get a large spew of duplicates, request a recalibration straight up. Based on earlier work by Paul Fox.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a "hgpk_mode" sysfs attribute that allows selection between 3 options: Mouse (the existing option), GlideSensor and PenTablet. GlideSensor is an enhanced protocol for the regular touchpad mode that additionally reports pressure and uses absolute coordinates. We suspect that it may be more reliable than mouse mode in some environments. PenTablet mode puts the touchpad into resistive mode, you must then use a stylus as an input. We suspect this is the most reliable way to drive the touchpad. The GlideSensor and PenTablet devices expose themselves with the intention of being combined with the synaptics X11 input driver.

(Models known to be like this include 6110344, 6110668, 1390876, 1386887, and possibly others.) When the connector is rewired or adapter to an AT-DIN or PS/2 connector, they can be connected to a standard PC, with three caveats: a) They can only use scancode set 3; requests to use anything else are quietly ignored. b) The AT Command to request Make, Break and Repeat codes is not properly interpreted. c) The top function keys on a 122 key keyboard, and the arrow/edit keys in the middle of the board send non-standard scancodes. C) is easily taken care of in userspace, by use of setkeycodes B) can be taken care of by a userspace hack (that makes the kernel complain in dmesg) A) is fixable in theory, but on the keyboard i tested on (6110668), it seems to be detected unoverridably as Set 2, causing userspace oddities that make it harder to fix C). Enclosed is a small patch to the kernel that fixes A) and B) in the kernel, making it much easier to fix C) in userspace. It adds a single kernel command line parameter that overrides the detection that sets these boards as set 2, and instead of sending the Make-break-repeat command to the keyboard, it sends the make-break command, which is properly recognized by these keyboards. Software level key repeating seems to make up for the lack of hardware repeat codes perfectly. Without manually setting the command line parameter (tentatively named atkbd.terminal), this code has no effect, and the driver works exactly as before.
