Struct SyncSupport 

pub struct SyncSupport {
    pub export_sync_file: bool,
    pub import_sync_file: bool,
}

Whether GPU completion can be handed to another component as a fence.

Fields

export_sync_file: bool

Can export a sync_file fd from a fence, for use as IN_FENCE_FD on an atomic commit.

import_sync_file: bool

Can import a sync_file fd and wait on it on the GPU timeline.

Implementations

impl SyncSupport

pub const fn supports_explicit_scanout(self) -> bool

Whether the frame loop can stay fully explicit on the DRM path.

When false, the DRM target must wait on the CPU before committing. That is correct but slower, and on Tier-1 hardware it is a driver bug to chase rather than a state to settle into, so callers are expected to log it loudly.
