DRM_CRTC_HELPER_SET_(9)		 DRM Internals	       DRM_CRTC_HELPER_SET_(9)

NAME
       drm_crtc_helper_set_mode - internal helper to set a mode

SYNOPSIS
       bool drm_crtc_helper_set_mode(struct drm_crtc * crtc,
				     struct drm_display_mode * mode, int x,
				     int y, struct drm_framebuffer * old_fb);

ARGUMENTS
       crtc
	   CRTC to program

       mode
	   mode to use

       x
	   horizontal offset into the surface

       y
	   vertical offset into the surface

       old_fb
	   old framebuffer, for cleanup

LOCKING
       Caller must hold mode config lock.

       Try to set mode on crtc. Give crtc and its associated connectors a
       chance to fixup or reject the mode prior to trying to set it. This is
       an internal helper that drivers could e.g. use to update properties
       that require the entire output pipe to be disabled and re-enabled in a
       new configuration. For example for changing whether audio is enabled on
       a hdmi link or for changing panel fitter or dither attributes. It is
       also called by the drm_crtc_helper_set_config helper function to drive
       the mode setting sequence.

RETURNS
       True if the mode was set successfully, or false otherwise.
