# The following two BoardConfig variables define (respectively):
#
#   - The phase offset between hardware vsync and when apps are woken up by the
#     Choreographer callback
#   - The phase offset between hardware vsync and when SurfaceFlinger wakes up
#     to consume input
#
# Their values can be tuned to trade off between display pipeline latency (both
# overall latency and the lengths of the app --> SF and SF --> display phases)
# and frame delivery jitter (which typically manifests as "jank" or "jerkiness"
# while interacting with the device). The default values should produce a
# relatively low amount of jitter at the expense of roughly two frames of
# app --> display latency, and unless significant testing is performed to avoid
# increased display jitter (both manual investigation using systrace [1] and
# automated testing using dumpsys gfxinfo [2] are recommended), they should not
# be modified.
