Hi,
I experience rendering issues using ARM closed user space libraries distributed with ZynqMP for Mali400 (libMali.so.9.0) and Qt Data Visualisation library running under both Wayland or EGLFS on Linux kernel 5.10.0-xilinx-v2021.2. The rendered image looks like this:
while when I switch to mesa 21.2.4 and the open source LIMA driver the scene is rendered as intended (the axes are rendered properly):
Unfortunately, the performance of the open source driver in this scene is 5 times worse (~50fps vs ~14fps) thus unacceptable.
The ARM user-space library for this device is quite old. Does the newer version of the library for this device exist? Would you have any suggestions on how to address this problem?
Thank you for your reply Peter Harris and sorry for the delay (vacation period)
I have asked Xilinx before (link), but no reply so far.What do you mean by API behaviour? As I use Qt Data Visualisation library I am already quite high from direct OpenGL calls... With QT debug flags, I don't need anything specific. Is it possible to debug ARM user-space library?
