Detailed Description

Field Documentation
◆ base
| struct comp_target comp_target_swapchain::base |
Base target.
Referenced by comp_target_swapchain_init_and_set_fnptrs(), comp_target_swapchain_override_extents(), and comp_window_mswin_thread().
◆ compositor_extent
| bool comp_target_swapchain::compositor_extent |
Should we ignore the compositor's preferred extents.
Some targets, like the direct mode ones, requires a particular set of dimensions.
Referenced by comp_target_swapchain_override_extents().
◆ current_frame_id
| int64_t comp_target_swapchain::current_frame_id |
Also works as a frame index.
◆ display
| VkDisplayKHR comp_target_swapchain::display |
The current display used for direct mode, VK_NULL_HANDLE else.
◆ event_thread
| struct os_thread_helper comp_target_swapchain::event_thread |
Thread waiting on vblank_event_fence (first pixel out).
◆ extent
| VkExtent2D comp_target_swapchain::extent |
The extents that a sub-class wants us to use, see ignore_compositor_extent above.
Referenced by comp_target_swapchain_override_extents().
◆ has_logged_info
| bool comp_target_swapchain::has_logged_info |
We print swapchain info as INFO the first time we create a VkSWapchain, this keeps track if we have done it.
◆ has_started
| bool comp_target_swapchain::has_started |
Must only be accessed from main compositor thread.
◆ last_vblank_ns
| uint64_t comp_target_swapchain::last_vblank_ns |
Protected by event_thread lock.
◆ present_mode
| VkPresentModeKHR comp_target_swapchain::present_mode |
Present mode that the system must support.
◆ should_wait
| bool comp_target_swapchain::should_wait |
Protected by event_thread lock.
◆ timing_usage
| enum comp_target_display_timing_usage comp_target_swapchain::timing_usage |
If we should use display timing.
Referenced by comp_target_swapchain_init_and_set_fnptrs().
◆ upc
| struct u_pacing_compositor* comp_target_swapchain::upc |
Compositor frame pacing helper.
