Advice on Qt Framework qualification for cutom hardware

[uvijay]

Hi Everyone,

I am trying to evaluate Qt6.5 Framework for a specific custom hardware using GPU to qualify.
Anyone have any idea on what are all the components i need to verify with respect to HW.
my main target is to check the UI responsiveness, Memory utilizations, leaks, CPU utilization etc.,

Your question is so broad that it is impossible to give any kind of answer.

Qt uses an event-driven architecture to respond to hardware and GUI inputs. If you write an application in such a way that Qt can never service its event loop (for example, a compute-intensive application that never gives execution control back to Qt), then the GUI will be frozen and the event loop cannot respond to inputs that generate events (like input ready to read on a serial port or mouse clicks).

There are no particular problems using a GPU in a Qt application as long as you return control from the GPU side frequently enough to keep the GUI "alive". Alternatively, you could run the GPU code from a non-GUI thread and use inter-thread signals and slots to feed data back to the GUI for display.

To evaluate Qt6.5 on your custom hardware, focus on testing UI responsiveness using Qt's QTest and profiler tools, and monitor memory utilization and leaks with tools like Valgrind or AddressSanitizer. Assess CPU and GPU utilization through Qt Quick Profiler, and consider using OpenGL or Vulkan profiling for GPU performance.
