Use a macro for `nlongs` so it can be used in constant expression

2020-01-26T14:00:32+00:00

This way, it can be used to specify the `absbits` array size (in `mtdev_configure`) without making it a VLA. VLAs are an optional feature in C11, and in this case we can determine the array size statically. This also matches the macros used in libevdev and libinput.

caps.c: declare mtdev_set_slots() static

2017-11-29T21:15:52+00:00

mtdev_set_slots() is only used internally, so it should be static. Signed-off-by: Martin Kepplinger

Replace hardcoded 11 with a define

2013-07-31T00:05:49+00:00

The 11 comes from the legacy API that we need to be binary compatible with. Make this clear with a define and a comment. Signed-off-by: Peter Hutterer

Add support for kernel MT slot state retrieval

2012-02-16T15:33:53+00:00

From kernel 3.4, extraction of the MT slot state is supported via the EVIOGMTSLOTS ioctl. This patch initializes the slots using that information. Signed-off-by: Henrik Rydberg

Introduce a stable ABI

2010-12-22T17:29:00+00:00

The current mtdev is not ABI stable, and the upcoming additions to the kernel api will break ABI. This patch starts the process of keeping binary compatibility with old programs, by moving the abi-specific parts under a special flag, MTDEV_NO_LEGACY_API, and makes sure the internal parts compiles with MTDEV_NO_LEGACY_API set. This way, older programs will still work, old programs will still compile, and new programs will be able to use the additions. Signed-off-by: Henrik Rydberg

Fall back to single-touch position and pressure dimensions

2010-09-07T14:08:44+00:00

In case mtdev is driving a non-MT device, basic dimensions are not set properly. Fall back on ABS_X/Y and ABS_PRESSURE, such that basic pointer operations can be supported through mtdev. Signed-off-by: Henrik Rydberg

Apply new package title to all files

2010-06-22T09:55:04+00:00

This patch changes the package description title in all relevant files, and touches up the README. All systems go. Signed-off-by: Henrik Rydberg

Unused slot is denoted by MT_TRACKING_ID == -1

2010-06-21T22:44:40+00:00

The current MT slot protocol allows any tracking id outside the range specified by the device to denote an unused slot. This is difficult to handle in userspace, since the valid range is unknown. This patch tightens the definition of a valid tracking id to always lie in the range [0, MT_ID_MAX], and uses the value -1 to denote an unused slot.
