keep it going…

Given that GSoC ’08 is getting close to the end, strategy number 2 showed more feasible to proceed my work. Strategy #3 would be a lot of fun but would imply a hell massive codification as well (also a little out of our scope). Unfortunately no-no for now.

Google Summer of Code 2008

April 29, 2008

I’m very happy to say that I was selected again to work on Google Summer of Code with X.Org Foundation. Daniel will be my mentor again. Thanks Google. Thanks X.Org!

In the last year we did a nice work separating the input event generation code of the X server into a different thread. We saw some performance improvement there specially because the implementation is not using signals anymore to wake up the server when some device emits an event. The reason why is that when a process is in the uninterruptible sleep (D state) signals are delayed and the mouse cursor lags.

The idea now is to continue the work and put the event processing stage in the separate thread as well. This will result in a lot of structures locks and will be very challenger. I’ll be posting all my advances here.
