[PATCH] Preliminary support for Razer Blade multitouch touchpads

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hey guys,

Attached is a patch for synaptics-usb made against commit
8177a9d79c0e942dcac3312f15585d0344d505a5 of Linus's git tree (the one
commit *right after* 3.10-rc6). It's *extremely* preliminary and there
are still a few glitches -- namely, the touchpad sends input samples
*a lot* and X and Y are never the same value twice, even when the
finger for that packet hasn't moved. I'm also not entirely sure that
the field I'm calling "pressure" is actually pressure -- it might
actually be orientation or something similar, because the values I
manage to get out of it don't seem to be related at all to the
pressure applied to the touchpad. I'm not exactly sure how to tease
that out.

Really, the purpose of sending this incomplete patch in is to request
comments and feedback about how to proceed. I could probably set a
threshold for position changes, but that doesn't seem to be the right
course of action at this level. (Further fixes would be nice, too!)

Please let me know what you think. Thank you!

Thanks,

Zach
