How to run Orin display in One-Shot mode?

Orin’s TRM says that Orin supports One-Shot and Continuous display modes,
How can I enable One-Shot mode? (I am using DRM)
Thank you


Which part of document are you referring to?

Section “Display Controller” in “TECHNICAL REFERENCE MANUAL NVIDIA Orin Series System-on-Chip” has subsection “1.4 Features” which says “One-Shot and Continuous display modes”
Elsewhere it says: “In OneShot mode, frames are only generated one at a time as dictated by software.”


This is not enabled. TRM document is for hardware spec. But the driver does not enable everything list on it.

Is it possible to enable it directly using registers?
