Hi all,
I assume that I found a possible source of the bad usbtablet update rate.
I did some git bisectioning but I didn't get a usable result due to too
many merges (or maybe my little knowledge to git), so I proceeded with some
manual bisectioning by manually selecting commits and tested them.
The problem was that the usbtablet update-rate in qemu-kvm-1.0 was really
bad compared to qemu-kvm-0.15.0.
The first commit where the cursor worked but the update rate was bad is
7cb78eec5cdf6e4131613c64cc1a29476f327242
Before this commit the usbtablet didn't work (no grabbing was possible).
But in 0.15.0 it worked. So I continued searching for interesting points
between these versions.
One point was the SDL commit done 2011-08-05 by Jan Kiszka.
There I found changes that affected the -full-screen option.
So I took the version from the commit above and just started with the
-full-screen option.
And everything was fine (qemu-kvm-1.0 as well)! The update rate is very
good with this option.
But I was not able to find the real change that caused the bad update rate.
Jan - is it possible to track down with this information the cause of the
bad update rate? It seems to be related to SDL - the VNC option is working
fine without -full-screen.
I would like to work without the -full-screen option.
Thanks.
Best regards,
Erik
