2013-07-07Input: elantech - fix for newer hardware versions (v7)Matteo Delfino1-8/+9
* Fix version recognition in elantech_set_properties The new hardware reports itself as v7 but the packets' structure is unaltered. * Fix packet type recognition in elantech_packet_check_v4 The bitmask used for v6 is too wide, only the last three bits of the third byte in a packet (packet[3] & 0x03) are actually used to distinguish between packet types. Starting from v7, additional information (to be interpreted) is stored in the remaining bits (packets[3] & 0x1c). In addition, the value stored in (packet[0] & 0x0c) is no longer a constant but contains additional information yet to be deciphered. This change should be backwards compatible with v6 hardware.

In TSG4, register map is 512bytes long and to access all of it, one bit from address byte is used (which bit to use differs for I2C and SPI); Since common code used for TSG3 and TSG4 for I2C, this parameter wrongly used as u8. TSG3 does not access beyond 255 bytes but TSG4 may.

2013-07-01Input: add OLPC AP-SP driverDaniel Drake4-0/+311
The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT keyboard, yet they do not have a hardware PS/2 controller. Instead, a firmware runs on a dedicated core ("Security Processor", part of the SoC) that acts as a PS/2 controller through bit-banging. Communication between the main cpu (Application Processor) and the Security Processor happens via a standard command mechanism implemented by the SoC. Add a driver for this interface to enable keyboard/mouse input on this platform.

This is effectively already in force through input_mt_init_slots, and uinput too ignores the actual minimum.

2013-06-10Input: evdev - flush queues during EVIOCGKEY-like ioctlsDavid Herrmann1-4/+129
If userspace requests current KEY-state, they very likely assume that no such events are pending in the output queue of the evdev device. Otherwise, they will parse events which they already handled via EVIOCGKEY(). For XKB applications this can cause irreversible keyboard states if a modifier is locked multiple times because a CTRL-DOWN event is handled once via EVIOCGKEY() and once from the queue via read(), even though it should handle it only once. Therefore, lets do the only logical thing and flush the evdev queue atomically during this ioctl. We only flush events that are affected by the given ioctl. This only affects boolean events like KEY, SND, SW and LED. ABS, REL and others are not affected as duplicate events can be handled gracefully by user-space. Note: This actually breaks semantics of the evdev ABI. However, investigations showed that userspace already expects the new semantics and we end up fixing at least all XKB applications. All applications that are aware of this race-condition mirror the KEY state for each open-file and detect/drop duplicate events. Hence, they do not care whether duplicates are posted or not and work fine with this fix. Also note that we need proper locking to guarantee atomicity and avoid dead-locks. event_lock must be locked before queue_lock (see input-core). However, we can safely release event_lock while flushing the queue. This allows the input-core to proceed with pending events and only stop if it needs our queue_lock to post new events. This should guarantee that we don't block event-dispatching for too long while flushing a single event queue.
