I've added some inline comments about Linux device names, IDs and properties.
Here is a patch that I'm using on top of this series right now:
| sys/dev/atkbdc/psm.c | ||
|---|---|---|
| 923 ↗ | (On Diff #26996) | This is now also used for the Evdev device names. Maybe it would be better to expose the same devices names as Linux does in a seperate function and use that for Evdev devices? Then, scripts that use those names would be compatible. |
| 1663 ↗ | (On Diff #26996) | This should probably be 0x0007 to match the value defined in psmouse.h from Linux. |
| 1724 ↗ | (On Diff #26996) | For a TrackPoint, "INPUT_PROP_POINTING_STICK" should also be set. |
| 1813 ↗ | (On Diff #26996) | This duplicates the MOUSE_MODEL_TRACKPOINT name from above. |

Giant-locked version of the patch.
After some discussion with bde@ (on arch@ and private) it is turned out that nothing but Giant can be used to serialize access to I8042 ports currently.
This version obsoletes part1 and part2 and can be applied to unmodified CURRENT (and 11STABLE as well).
