Hi,
We are experiencing poor performance with QT5.1 + elgfs plugin built with Yocto build system compared to the same application running with QT4.8. There is also a difference between Yocto and Arago distributions. The CPU load is also significantly higher with QT5 than QT4.8. Could it be that we have some issues with the build system?Is it possible to use the hard fp gcc compilers with Yocto?
Also is there any support for 3.8 and newer drivers for GPU parts?
