Enum PanelSelfRefresh 

#[non_exhaustive]
pub enum PanelSelfRefresh {
    Unknown,
    None,
    Possible,
}

Whether a connected panel might hold its image without a flip.

Telemetry only, and deliberately not authoritative: PSR has no portable KMS property, so the best available signal is the connector type. Nothing gates behavior on this — a frame-economy decision that skipped a commit because it guessed the panel would self-refresh, and guessed wrong, freezes the display.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown

No connected connector, or the set could not be read.

None

Every connected connector is external, so none can self-refresh.

Possible

A connected eDP or DSI panel, which may support it.
