Public Member Functions
struct comp_target *	comp_window_direct_nvidia_create (struct comp_compositor *c)
	Create a direct surface to an HMD on NVIDIA.

Data Fields
struct comp_target_swapchain	base
Display *	dpy
struct comp_window_direct_nvidia_display *	displays
uint16_t	display_count
Data Fields inherited from comp_target_swapchain
struct comp_target	base
	Base target.
struct u_pacing_compositor *	upc
	Compositor frame pacing helper.
enum comp_target_display_timing_usage	timing_usage
	If we should use display timing.
int64_t	current_frame_id
	Also works as a frame index.
struct {
bool   compositor_extent
	Should we ignore the compositor's preferred extents. More...
VkExtent2D   extent
	The extents that a sub-class wants us to use, see ignore_compositor_extent above. More...
}	override
struct {
VkSwapchainKHR   handle
}	swapchain
struct {
VkSurfaceKHR   handle
VkSurfaceFormatKHR   format
}	surface
struct {
VkFormat   color_format
VkColorSpaceKHR   color_space
}	preferred
VkPresentModeKHR	present_mode
	Present mode that the system must support.
VkDisplayKHR	display
	The current display used for direct mode, VK_NULL_HANDLE else.
struct {
bool   thread_running
	Must only be accessed from main compositor thread. More...
bool   should_wait
	Protected by event_thread lock. More...
uint64_t   last_vblank_ns
	Protected by event_thread lock. More...
struct os_thread_helper   event_thread
	Thread waiting on vblank_event_fence (first pixel out). More...
bool   event_active
	Skipping the event on the first vblank avoids a spurious VK_ERROR_OUT_OF_HOST_MEMORY error. More...
}	vblank
bool	has_logged_info
	We print swapchain info as INFO the first time we create a VkSWapchain, this keeps track if we have done it.

Additional Inherited Members
Protected Member Functions inherited from comp_target_swapchain
void	comp_target_swapchain_init_and_set_fnptrs (struct comp_target_swapchain *cts, enum comp_target_display_timing_usage timing_usage)
	Pre Vulkan initialisation, sets function pointers.
void	comp_target_swapchain_override_extents (struct comp_target_swapchain *cts, VkExtent2D extent)
	Set that any size from the compositor should be ignored and that given size must be used for the VkSwapchain the helper code creates.
void	comp_target_swapchain_cleanup (struct comp_target_swapchain *cts)
	Free all managed resources on the given comp_target_swapchain, does not free the struct itself.
