* Keep logical buttons separate from the hardware onesHenrik Rydberg2010-04-151-4/+8
| | | | | | | | | The button extraction currently modifies the MTState buttons, upsetting the semantics in a bad way. This patch adds the logical button state to the Memory structure, and uses it to compute the logical button change. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
* Only extract movement from identical finger configurationsHenrik Rydberg2010-04-151-16/+21
| | | | | | | | | The current code would extract movement from a rapid change from one finger to the next, resulting in unwanted jumps. This patch first checks that the finger configuration is the same before attempting to extract movement. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
* Reorganize gesture codeHenrik Rydberg2010-04-151-18/+32
| | | | | | | Break out extraction of movement, buttons and type. Only code traversal, no logical changes. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>
* Introduce the MTStateHenrik Rydberg2010-04-151-11/+12
| | | | | | | | | | | | | | | The HWState keeps, for good reason, both touching fingers and fingers going away. However, this implies that additional logic is needed to keep track of the number of actual touching fingers. In particular the test for touching fingers is somewhat misplaced in hwstate.c. Moreover, HWState should only exist in one instance, since it contains data which does not need to be referred to during gesture extraction. This patch introduces the MTState structure, which keeps more digested data for gesture extraction. In particular, it only keeps the actual touches.

* Rename State to HWStateHenrik Rydberg2010-04-151-11/+11
| | | | | | | Rename the hardware state struct State to HWState, to make room for additional state structures. Signed-off-by: Henrik Rydberg <rydberg@euromail.se>

* janitor: stick to kernel-style formattingalpha-1Henrik Rydberg2010-02-011-1/+2
| | | | | | With this commit, the whole code base complies with the kernel format style, and patches can be checked against the kernel-provided ./scripts/checkpatch.pl
