48 # Set the phase offset of the system's vsync event relative to the hardware
49 # vsync. The system's vsync event drives Choreographer and SurfaceFlinger's
50 # rendering. This value is the number of nanoseconds after the hardware vsync
51 # that the system vsync event will occur.
53 # This phase offset allows adjustment of the minimum latency from application
54 # wake-up (by Choregographer) time to the time at which the resulting window
55 # image is displayed. This value may be either positive (after the HW vsync)
56 # or negative (before the HW vsync). Setting it to 0 will result in a
57 # minimum latency of two vsync periods because the app and SurfaceFlinger
58 # will run just after the HW vsync. Setting it to a positive number will
59 # result in the minimum latency being:
61 # (2 * VSYNC_PERIOD - (vsyncPhaseOffsetNs % VSYNC_PERIOD))
63 # Note that reducing this latency makes it more likely for the applications
64 # to not have their window content image ready in time. When this happens
65 # the latency will end up being an additional vsync period, and animations
66 # will hiccup. Therefore, this latency should be tuned somewhat
67 # conservatively (or at least with awareness of the trade-off being made).
