Hi amit
when the system is running out of memory bandwidth one can start
experimenting problems with the display which gives the warning message
imx-ipuv3 imx-ipuv3.0: IPU Warning - IPU_INT_STAT_10 = 0x00100000.
This means a synchronous display error interrupt, as a result of an error during
access to a synchronous display. one solution to this issue is
reducing the display resolution, framerate, frame buffer bits
per pixel or any other measure that helps to reduce the memory bandwidth utilization.
