2011-11-15Input: synaptics - update OLPC XO exclusionDaniel Drake1-8/+5
We have determined that the jumpiness previously seen when using the synaptics kernel mouse driver on OLPC XO was due to not using the synaptics X11 userspace driver - the xf86-input-evdev driver was interpreting 'finger near pad' signals as movements. Newer versions of xf86-input-evdev fix this issue. Additionally, the synaptics kernel driver is now usable on this platform, but only when run in relative mode. Update the comment and refine the check to allow the synaptics driver to run on OLPC XO in relative mode. We will continue investigating the EC issue as time becomes available.

2011-11-10Input: synaptics - add support for Relative modeDaniel Drake4-48/+152
Currently, the synaptics driver puts the device into Absolute mode. As explained in the synaptics documentation section 3.2, in this mode, the device sends a continuous stream of packets at the maximum rate to the host when the user's fingers are near or on the pad or pressing buttons, and continues streaming for 1 second afterwards. These packets are even sent when there is no new information to report, even when they are duplicates of the previous packet. For embedded systems this is a bit much - it results in a huge and uninterrupted stream of interrupts at high rate. This patch adds support for Relative mode, which can be selected as a new psmouse protocol. In this mode, the device does not send duplicate packets and acts like a standard PS/2 mouse. However, synaptics-specific functionality is still available, such as the ability to set the packet rate, and rather than disabling gestures and taps at the hardware level unconditionally, a 'synaptics_disable_gesture' sysfs attribute has been added to allow control of this functionality. This solves a long standing OLPC issue: synaptics hardware enables tap to click by default (even in the default relative mode), but we have found this to be inappropriate for young children and first time computer users. Enabling the synaptics driver disables tap-to-click, but we have previously been unable to use this because it also enables Absolute mode, which is too "spammy" for our desires and actually overloads our EC with its continuous stream of packets. Now we can enable the synaptics driver, disabling tap to click while retaining the less noisy Relative mode. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2011-11-08Input: wacom - ignore unwanted bamboo packetsChris Bagwell1-0/+9
Bamboo's Pen and Touch packets always start with a value of 0x02 in first byte. In 3rd gen Bamboo's, the hw is now periodically sending some additional packets with unrelated data and uses a value other than 0x02 to inform driver this. Ignore those packets now. This was reported by users as bad behavior in Gimp. The invalid packets being processed made the stylus report out of proximity for the 1 packet and this triggered some secondary bug which caused Gimp to stop drawing until user really took pen out of proximity of tablet.

The ADP5585 family keypad decoder and IO expander is similar to the ADP5589, however it features less IO pins, and lacks hardware assisted key-lock functionality.

2011-10-13Input: force feedback - potential integer wrap in input_ff_create()Dan Carpenter1-3/+8
The problem here is that max_effects can wrap on 32 bits systems. We'd allocate a smaller amount of data than sizeof(struct ff_device). The call to kcalloc() on the next line would fail but it would write the NULL return outside of the memory we just allocated causing data corruption. The call path is that uinput_setup_device() get ->ff_effects_max from the user and sets the value in the ->private_data struct. From there it is: -> uinput_ioctl_handler() -> uinput_create_device() -> input_ff_create(dev, udev->ff_effects_max); I've also changed ff_effects_max so it's an unsigned int instead of a signed int as a cleanup.
