Hello,

  PRE/PRG feature can help to avoid a potential IPU display under-run in high
loading applications. This feature is "visible" under very heavy loaded system.

Please use IPU driver description in Linux documentation how to configure

the PRE/PRG. In particular look at section 6.3.2 [Image Processing Unit (IPU)]

of "i.MX_Reference_Manual.pdf" in L4.14.78.

Have a great day,
Yuri
