TDA4VM: CPU performance degradation caused by GPU application

Zongsheng Chen
Prodigy 100 points

Part Number: TDA4VM

Hi,

    One processes A has a CPU utilization rate of 38.5%. When I run a GPU application,  for example vx_app_arm_opengl_mosaic，the CPU utilization rate of processes A will increase to 65.6%. The CPU utilization of many service processes in the system will also increase.

    SDK version: ti-processor-sdk-linux-j7-evm-07_02_00_07.

    What causes this problem and how to solve it?

Thanks,

Chen Zongsheng
