Collaboration diagram for u_pc_display_timing_config:

Data Fields
int64_t	present_to_display_offset_ns
	How long after "present" is the image actually displayed. More...

int64_t	margin_ns
	Extra margin that is added to compositor time, between end of draw and present. More...

Frame-Relative Values
All these values are in "percentage points of the nominal frame period" so they can work across devices of varying refresh rate/display interval.
uint32_t	comp_time_fraction
	The initial estimate of how much time the compositor needs. More...

uint32_t	comp_time_max_fraction
	The maximum time we allow to the compositor. More...

uint32_t	adjust_missed_fraction
	When missing a frame, back off in these increments. More...

uint32_t	adjust_non_miss_fraction
	When not missing frames but adjusting app time at these increments. More...
