Member Function Documentation

void mir::graphics::X::DisplayGroup::for_each_display_buffer ( std::function< void(graphics::DisplayBuffer &)> const &  f )

override

void mir::graphics::X::DisplayGroup::post ( )

overridevirtual

Post the content of the DisplayBuffers associated with this DisplaySyncGroup.

The content of all the DisplayBuffers in this DisplaySyncGroup are guaranteed to be onscreen in the near future. On some platforms, this may wait a potentially long time for vsync.

Implements mir::graphics::DisplaySyncGroup.

std::chrono::milliseconds mir::graphics::X::DisplayGroup::recommended_sleep ( ) const

overridevirtual

Returns a recommendation to the compositor as to how long it should wait before sampling the scene for the next frame.

Sampling the scene too early results in up to one whole frame of extra lag if rendering is fast or skipped altogether (bypass/overlays). But sampling too late and we might miss the deadline. If unsure just return zero.

Implements mir::graphics::DisplaySyncGroup.
