Date: Sun, 10 Oct 2010 09:49:45 +0200 From: Henrik Rydberg <rydberg@...omail.se> To: Takashi Iwai <tiwai@...e.de>, Chase Douglas <chase.douglas@...onical.com> CC: linux-input@...r.kernel.org, Dmitry Torokhov <dmitry.torokhov@...il.com>, linux-kernel@...r.kernel.org Subject: Re: [PATCH 0/3] Input: synaptics - multitouch and multifinger support Takashi, Chase, talk about Heinz effect. :-) Rather than taking any of the patches, I was wondering if we could get a single patch including all the later findings and considerations on what devices should have the multitouch mode. Also, unless there is a really really good reason for it, without kernel parameters. After all, these patches should only add new functionality without regressions. Regarding the clickpad functionality, it is similar to the macbook pads with integrated buttons, which has been implemented in userspace. Regarding the tracking aspect of pointer emulation, Chase is completely right, and this is a generic problem for several drivers. Tracking a single point by picking the closest contact is a linear problem and could easily be performed in interrupt context. I suggest we add it directly to the synaptics driver and then revisit the question of adding generic tracking support to the kernel. Dmitry, how does that sound to you?
