202 Global sync consists of three signals, VSTARTUP, VUPDATE, and VREADY. These are
203 calculated by the Display Mode Library - DML (drivers/gpu/drm/amd/display/dc/dml)

225 The following picture shows how global sync allows for a mailbox style of
226 updates, i.e. it allows for multiple re-configurations between VUpdate
