PowerVR Insider

Currently, we are using GPU PowerVR GE8300.
Is there any way to verify its using system DMA or Internal DMA?
for GPU operation or for transferring FB data to display will it use system DMA?

Hi,
Thanks for update.
As suggested above, we registered and downloaded "PVRTuneComplete_2019_R1.tgz"package from PowerVR Insider Support.
Within the package “PVRPerfServer”, i am able to find x86, arm and QNX, but we are working on riscv platform, ad i am not able to find the out platform executable.

From “Downloads - Imagination Developers” we downloaded “PVRTune” from the download section.
After installing the downloaed on my x86 sustem, iw as able to find executable “PVRPerfServerDeveloper” for riscv paltform in the following path
“Imagination Technologies/PowerVR_Graphics/PowerVR_Tools/PVRTuneDeveloper/PVRPerfServer/Linux_riscv_64”.

As mentioned in the “PVRTune User Manual” PVRPerfServer should be run on target device.
when we try to run the executable “PVRPerfServerDeveloper”, we found the below error.

root@SOC:~# ./PVRPerfServerDeveloper
./PVRPerfServerDeveloper: error while loading shared libraries: libssp.so.0: cannot open shared object file: No such file or directory

when i try to run “PVRTuneDeveloperGUI” on my client x86 i am facing the below error

manoj@Manoj:~/Imagination Technologies/PowerVR_Graphics/PowerVR_Tools/PVRTuneDeveloper/GUI/Linux_x86_64$ ./PVRTuneDeveloperGUI
qt.qpa.plugin: Could not load the Qt platform plugin “xcb” in “” even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: wayland, xcb.

How can i resolve above error?
