AM6548: Improving the performance of "Qpainter lines" and "Qpainter circles" using Qt5 linuxfb

Hello,

My customer would like to improve the performance of "Qpainter lines" and "Qpainter circles" measured by qtperf-qt5.

Their application uses Qt to draw simple lines and rectangles repeatedly, but in that case they think that Wayland's structure is the bottleneck without drawing out the performance of the GPU.

Therefore, they expected that the performance would be improved by using linuxfb, but the result was the same even if I operated and measured while looking at the following.

https://software-dl.ti.com/processor-sdk-linux/esd/AM65X/07_01_00_17/exports/docs/linux/Foundational_Components/Graphics/QT_Graphics_Framework.html

Do you have any advice to get better performance on "Qpainter lines" or "Qpainter circles" with linuxfb in Qt5?

Regards,
