This reminds us that packaged kernel can be some distance away from our current kernel in git, I guess it only makes sense to explore current git kernel behaviours for touchscreen. |> Actual position averaging is pretty solved by the "median" patch stuff, |> there's some question about whether it's acceptable upstream I guess we |> are going to have to find out about. |> |> http://git.openmoko.org/?p=kernel.git;a=commitdiff;h=e007095586274313f7d469040ddd1c469a20165c | | I don't understand, is this usable in the moko or not? When you say | upstream you mean a merging with the standard linux upstream code or | with the openmoko stable? I didn't put it on stable branch yet because of a thread where folks were saying that upstream did not believe in any processing of touchscreen data in the driver. But, the driver is in a unique position to reduce the amount of and increase the quality of information passed to the input subsystem. Since it's really effective and I naturally like it since I did it, I would like to use it on our normal kernel, but it can conflict with this ~ get the kernel upstream meme. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkj9N74ACgkQOjLpvpq7dMqRoQCfQ64GSERyU2kCml6OdKJsf56n OpYAn21O5Z+UiXdF4T2YK5/eXy40sqfZ =rwnK -----END PGP SIGNATURE----- _______________________________________________ devel mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/devel
