PROCESSOR-SDK-J721E: PVRTune can't get GPU data in ProcessorSDK 8.0

Taekmin Lee

Hi,

I want to measure GPU data with ProcessorSDK 8.0's vision apps.
I made custom apps using OpenGL.(Capture → LDC → OpenGL → Display)

After running VisionApp(Custom App using OpenGL) for GPU measurement, PVRPerfServerDeveloper is run.

1. PVRPerfServerDeveloper v14.151: Segmentation fault (core dumped)

- It worked well in Processor SDK 7.0, 7.3.
- However, in Processor SDK 8.0, Segmentation fault occurs at the same time as the custom app run.

- It's the same if run PVRPerfServerDeveloper again.

2. PVRPerfServerDeveloper v14.143: GPU data unavailable!
- It's the PVRPerfServerDeveloper included in the Processor SDK. (rootfs/opt/img-powervr-sdk/PVRHub/PVRPerfServer)
- This version can't get GPU data.
- Also PVRPerfServer doesn't catch vision app is running. show this log.

3. PVRPerfServerDeveloper v14.151: It works on wayland
- I tested glmakr2-wayland on linux side (not installed RTOS), it works.

So, I think there is a conflict between PVRTune and VisionApps.
How can I measure GPU data in Processor SDK 8.0's vision apps?

Lee.
