Function Documentation

EGLNativeDisplayType kzsEGLGetNativeDisplay	(	const struct KzsDesktopNative *	desktopNative,
		const struct KzsDisplayNative *	displayNative,
		const struct KzsWindowNative *	windowNative
	)

kzsError kzsDisplayNativePageFlip	(	struct KzsDisplayNative *	displayNative,
		int	fd,
		int	fbId
	)

Schedule a page-flip, swap-buffers should be called prior to this.

This function internally first schedules a page flip with kzsDisplayNativePageFlipInvoke(), then waits for the synchronization using kzsDisplayNativePageFlipWait().

Parameters

displayNative	Handle to display-native.
fd	File handle to drm device or control-device.
fbId	Handle to the framebuffer.

kzsError kzsDisplayNativePageFlipInvoke	(	struct KzsDisplayNative *	displayNative,
		int	fd,
		int	fbId
	)

Queues to page flip to happen on next vblank.

Parameters

displayNative	Handle to display-native.
fd	File handle to drm device or control-device.
fbId	Handle to the framebuffer.

kzsError kzsDisplayNativePageFlipWait	(	struct KzsDisplayNative *	displayNative,
		int	fd
	)

Waits for vblank signal that is sent on page flip.

Must be called from the same thread as kzsDisplayNativePageFlipInvoke().

Parameters

displayNative	Handle to display-native.
fd	File handle to drm device or control-device.

kzsError kzsDisplayNativeModeSet	(	struct KzsDisplayNative *	displayNative,
		int	fd,
		int	fbId
	)

Set the mode for the display.

Parameters

displayNative	Handle to display-native.
fd	File handle to drm device or control-device.
fbId	Handle to the framebuffer.

kzsError kzsDisplayNativeRestoreMode	(	struct KzsDisplayNative *	displayNative,
		int	fd
	)

Restore original mode of the display.

Parameters

displayNative	Handle to display-native.
fd	File handle to drm device or control-device.
fbId	Handle to the framebuffer.

bool kzsDisplayNativeIsConnected ( struct KzsDisplayNative * displayNative )

Check if display is connected.

Parameters

displayNative Handle to display-native.
