Linux/TDA2PXEVM: [OpenGL] How to check the memory usage of OpenGL(GPU)

Part Number: TDA2PXEVM

Tool/software: Linux

Hello:

we're working on the VisionSDK3.0.4,

which memory region does OpenGL (GPU) allocated?
For Linux, how we can check the memory usage above?
Does the OpenGL(GPU) memory belong to application which is under /proc/$(pidof app)/status ?
How we can check the GPU cpu usage?
how to check the usage of SR1_FRAME_BUFFER_SIZE?

Thanks.

Hi,

SGX memory allocation is done from standard Linux kernel memory. You can use standard Linux kernel memory tracking tools to check memory status.

The memory allocated is split into two parts:
1. Application render surfaces - belong to app
2. Standard Graphics memory - belongs to kernel

GPU usage can be observed by using PVRTune. Please refer to:
processors.wiki.ti.com/index.php

Question #5 is not related to Graphics and is more for VisionSDK. Please log a separate ticket for that.

Regards,
Anand

The link in the wiki is unavailable for get the graphic sdk, and can you share the direct link that can access the PVRTune tool for visionSDK, thanks.

Hi Anand:

It works, the attachment is our target report, just wounder it's possible to distinguish how much memory that allocated by GPU, not application.

Hi,

As mentioned earlier, application allocated buffers are easy to compute. This is usually deterministic from application and dependent on number of layers, number of VBOs, number of textures, pixel format.

You can use meminfo to look at system allocated memory which includes GPU driver memory as well.

Anand
