Hi, Well, I am posting this as an RFC for 2 reasons: - I could not end up in a complete documentation on how the in-kernel tracking was working (patches 1/6 to 5/6) - I introduce a new input-mt API symbol, so I am pretty sure there will be some changes requested. (path 6/6) Anyway, this is the second part of the jumping cursors issue reported few months ago: https://bugs.freedesktop.org/show_bug.cgi?id=76722 Henrik if you have any pointers on how mathematically the reduced cost matrix and the adjust dual function works, I think that should be enough to document the code. I gave up trying to understand by hand (or with breakpoints), and all I know is that it works. Thanks for your feedback, Cheers, Benjamin Benjamin Tissoires (6): Input: mt: make input_mt_assign_slots() a little bit more readable Input: mt: Document input_mt_set_slots() Input: mt: document input_mt_set_matrix() Input: mt: document find_reduced_matrix() Input: mt: document adjust_dual() Input: mt: introduce dmax in in-kernel tracking drivers/input/input-mt.c | 184 +++++++++++++++++++++++++++++++++------- drivers/input/mouse/synaptics.c | 3 +- include/linux/input/mt.h | 4 + 3 files changed, 161 insertions(+), 30 deletions(-) -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
