1. A method for configuring an image data transfer time for sending image data from a processor to a display panel along a display path, the method comprising:
receiving, by the processor from the display panel, a display panel refresh interval indication indicating a display panel refresh interval of the display panel, the display panel refresh interval of the display panel corresponding to a time duration of a display period of the display panel, the display panel being configured to refresh each display period;
computing the image data transfer time based on the display panel refresh interval; and
configuring one or more components of the display path to support the computed image data transfer time,
wherein receiving the display panel refresh interval indication comprises receiving one or more display panel refresh interval indications indicating a plurality of display panel refresh intervals of the display panel corresponding to a plurality of display periods of the display panel, and wherein computing the image data transfer time comprises:
applying a temporal filter to the plurality of display panel refresh intervals to generate a filtered display panel refresh interval; and
computing the image data transfer time based on the filtered display panel refresh interval.
