amdgpu_dm_crtc_set_static_screen_optimze() maps sso_enable to the Replay and PSR1 vsync events. allow_sr_entry is an entry gate, but the helper currently applies it to both directions. A non-fast update clears allow_sr_entry. During a modeset, a separate hardware-programming event keeps self-refresh blocked while the stream is reprogrammed. If vblank is enabled before the entry delay expires, the ISM calls the helper with sso_enable false. The early return drops the disable request, so the vsync events are not set. After enough fast commits, allow_sr_entry becomes true and the hardware-programming event can be cleared. Since the vblank reference remains held, there is no further zero-to-one vblank transition to restore the missing vsync events. Replay or PSR1 can then become active while vblank is still enabled. Gate only requests that enable static-screen optimization. Always process disable requests so a vblank requestor keeps Replay and PSR1 blocked. On a Phoenix system, repeated SDDM-to-VT handoffs produced stuck flips followed by flip_done and commit-wait timeouts. The timeout was not observed with this change applied.
