Function Documentation

comp_multi_create_system_compositor()

xrt_result_t comp_multi_create_system_compositor	(	struct xrt_compositor_native *	xcn,
		struct u_pacing_app_factory *	upaf,
		const struct xrt_system_compositor_info *	xsci,
		bool	do_warm_start,
		struct xrt_system_compositor **	out_xsysc
	)

Todo:

Make the clients not go from IDLE to READY before we have completed a first frame.

system_compositor_set_state()

static xrt_result_t system_compositor_set_state ( struct xrt_system_compositor *  xsc, struct xrt_compositor *  xc, bool  visible, bool  focused  )

static

Todo:

Locking?

system_compositor_set_z_order()

static xrt_result_t system_compositor_set_z_order ( struct xrt_system_compositor *  xsc, struct xrt_compositor *  xc, int64_t  z_order  )

static

Todo:

Locking?

References multi_compositor::msc, multi_compositor(), and XRT_SUCCESS.

update_session_state_locked()

static void update_session_state_locked ( struct multi_system_compositor *  msc )

static

Todo:

Make this not be hardcoded.
