This is a single-patch series that increases DCN314 self-refresh (SR) enter/exit latency values by 1μs to fix display underflow on laptops with LPDDR5 memory. The change is simple, low-risk, and targets a specific reported bug. The approach — adding margin to timing parameters — is a common and well-understood fix pattern for display underflow issues in the AMDGPU display stack.
**Concern:** The commit message says "It's unclear why it only occurs on specific desktop contents," which is honest but not fully reassuring. The fix is empirical (add 1μs of margin) rather than root-cause-driven. That said, this is typical for display watermark tuning and the values are conservative bumps.
