Dear Google
Our preliminary analysis onComposerHalVsync did not complete the VSP-setPeriod setting At this time, the upper layer calls setDesiredDisplayModeSpecs Finally, at this time, the condition satisfies VSP-period==VSR-setPeriod, the code goes to endPeriodTransition and sets mPeriodConfirmationInProgress to false Because the VSP-setPeriod is not set, the deviation of addVsyncTimestamp is always large, and the vsync model has been unable to complete the calibration
